Gate blush Troubleshooting

gate blush defects

What is gate blush?

Gate blush is a molding defects commonly caused at the gate location of injection molded part, It shows as rings or ripples in the mold cavity surrounding the gate area. This defect occurs when plastics material flow across the mold cavity rather than forming a fountain flow and freezing to the mold cavity. As more material enters the mold cavity, it erodes the material off of the mold surface, causing the blushed appearance, gate blush sometimes we call gate shear defects.

gate blush defects

Cause

Injection pressure and speed is too high.

Gate blush defects caused by high pressures and speed going through a mold gate at the 1st stage injection, the melt plastics pass through the gate too quickly so that create excessive shear.

Mold temperature too high.

The mold temperature too low or too high that could cause the gate blush problems, so it can be important to understand the correct mold temperature for different plastics materials. Gate blush is a strange phenomenon that can be magnified by the steel temperature and both too low and too high steel temperatures may lead to a poor formation of the initial plastic through the gate.

Some of materials like ABS, PC, PA66, increase the mold temperature will improve the mold surface, so the gate blush will be improved as well.

Mold gate size is too small

Gate size will mostly cause this gate blush issue as well, small size that requires the high injection pressure and speed.

Solution

There are some solutions can be applied to solve gate blush. The first is to reduce the injection speed so that the plastic resin do not extend as much as with higher speeds. This will lay down a clean skin of material and improve the gate blush issue. Reduce the injection speed can also be used, at the beginning of injection to start with a slow injection speed, switch to a higher injection speed once the cavity is filled.

Increase the mold temperature to improve this gate blush issue, low temperature will occur the material hard to fill and this will require the high injection speed and pressure as well.

Increase the gate size and add a cold slug well, big gate size will reduce the gate shear force, add a cold slug well is to receive the first slug of plastics material from the first step of nozzle and keep same material temperature with the flow path of the hotter material behind. Lack of a cold slug well can force this colder material into the gate and into the part showing up as gate blush. It is very important to add big cold slug well at each end of runner.

Injection molded parts ribs design tips

Injection Molding Electronics

Why need design ribs on the injection molded parts

Injection molding technology is the most common manufacturing technology for producing high volume of plastics parts in the world. The purpose of these parts can range from a picture frame that is never touched to a gear that is used in a moving assembly every day. Many times, the stiffness of a part must increase due to the load applied to the plastic part design. When designing strength into an injection molded part, considerations must be made to accommodate for the manufacturing process. This is where ribs and supports come into the design.

Ribs are thin wall protrusions that extend perpendicularly from a wall or plane. supports are triangular shaped ribs that support a main wall. Ribs and gussets add strength and rigidity to primary walls without the dangers and high costs caused by excessive wall thickness.

DFM Design for Manufacturing

DFM Design for Manufacturing

 

If the mean wall is too thick, sink marks and distortion may occur on the molded part, resulting in a rejected part design. Ribs solve this problem by providing additional support for thin walls, and are in fact, more effective structurally than just a thick wall. Along with being stronger, ribs also require less material than thick mean walls making them the economical choice as well.

 

Ribs increase the durability and quality of your part while reducing material cost, but if used incorrectly, can have negative effects on the aesthetics of your molded part. The area where the rib intersects with the main wall will experience a thicker plastic section. If the rib is too thick it will cause a sink mark in the main wall due to inconsistent cooling rates. To avoid this there are several rules to follow when using ribs in your design:

Please send us your part design, we will review your part design and send you a completely DFM report for your project, this will save you a lots of cost and time.

Mold Texturing Surface Finish

Mold texturing

Are you looking for different mold texturing surface finishs on a plastic part cavity side? Plastic parts not only benefit from designs that are pleasing to the eye, but they also benefit from the way a product feels when handled. Depending on the application, you may want your plastic mold part to be as smooth as glass or possess a rough feel to indicate strength and durability. One way to injection mold a molded part with a unique look with different grain on the part surface, which we call mold texture surface finish.

Mold texturing

What is Mold Texturing surface finish?

Mold Texturing surface is a process used to apply patterns to the mold cavity surface. This process allows flexibility in creating the final appearance of your parts. Mould Texturing finish is an integral piece in overall product development and should be considered during the design process to achieve the desired results. Mold Texture can be a functional component of design as well.  Some surface issue on molding part can be covered by the right texture. Is the part designed for frequent handling? Texture finish can be used to hide finger prints and improve the grip for the end user. Surface Texture can also be used to reduce part wear from friction.

Some important considerations to keep in mind when you plan to add texture surface finish on your plastic molded part

  • Which surface do you need to add texture finish? normally texture finish will go to the outside surface
  • what plastics will use for your plastic molding part? Thermosets, Ryanite, Glass Filled Nylon, Glass Filled Polypropylene, ABS, Polycarbonate, etc. different plastics material will usually require different draft for same texture finish.
  • What grade /type of texture finish do you need? on the market the most use of surfaces are VDI 3400 texture, leather texture, wood texture, etc., each type of texture has different grade of texture finish as well, for example VDI 3400 texture finished that has grade texture finish from VDI 12 to VDI 45, different grade of VDI texture requires different of draft angle.

In order to facilitate the removal of the finished product, there must be an appropriate draft angle in the ejection direction of the finished product; for finished products that do not bite, it is recommended to have at least 1°, and of course the larger the better.
For finished products with bite marks, depending on the type and depth of the bite marks, the angle should be at least 3~5° if possible.
VDI 3400 is Electric Discharge Pattern (EDM)
For VDI 3400, please refer to the table below: (Generally, it is better to add 1° to the angle)

Below is VDI3400 plastic surface finish chart

Part Thickness Design

injection molding thick wall

How to save injection molding cost by Part thickness design reduction

By do the DFM (Design For Manufacturing) report and mold flow analysis to keep part thickness down to the minimum but having the same strength, we have reduced cooling times by as much as 31 seconds!  As you can see by the table below example to show you how much you could save your injection molding cost,  it doesn’t take a big annual volume for the savings to add up.

AttributeValue
Volume of Plastic Reduced.06  Lbs.
Cost / Pound of Plastic$ 5.34
Material Savings / part$ .32
Cycle Time Reduction15 seconds
Machine Cost / Hour$60
Production cost saved / part$.25
Annual Part Volume10,000
Total Annual Savings$5,700

Theory

It has been shown that cooling time averages about 50% of the molding cycle for a typical plastic molded part. The additional 50% of the time consists of the filling, packing, and part ejection phases, which do not vary significantly from mold to mold. The cooling phase is the only phase that has any degree of variability.  This is because the cooling of a molded part is determined by the rate of mold heat removal.  Heat removal is impacted by many factors. Factors include the melt temperature, cooling channels design,  part thickness, and the material and mold steel’s thermal capabilities.

Part Thickness design

Out of all the factors, the part wall thickness is the easiest to impact. In short, the thinner the part, the faster the cycle time, the more molded parts per hour get made. Since the relationship of part thickness to cooling time is exponential, a small thickness reduction yields big cooling time reductions and big savings.

As stated on the Injection Pressure page, part thickness reductions increase the injection pressure. The fundamental limit of how thin you can make the part is the machines pressure capability assuming that the part will still meet design intent with a thinner wall.

Without the use of mold flow analysis the part thickness is usually designed so that it errors on the thick “safe” side to avoid fill problems.  However, with mold flow analysis, the thickness of the part can be iteratively reduced until the pressure reaches safe level (typically 17,000 psi). The process is usually complimented by performing a stress analysis to verify that the thinner walled part still meets the products design intent.  The FEA process usually adds ribs and gussets  to preserve the strength while using thinner walls.

If We have any plastic project that is ready to start make the plastic mold and massive production, you are welcome to send us, we will check the part design issues for you and send you a price for your reference.

Plastic Part Design Analysis

Product Design Service

Plastic Part Design Analysis Theory

The plastic part molding process is heavily affected by factors of the plastic part design. If the critical parameters of a part design are not set correctly, the part will have quality issues during the molding process. The most critical of these parameters is as follows:

  • Plastic Part wall thickness
  • Part flow length
  • Thickness transitions
  • plastic Part material
  • Location of gates
  • Number of gates
  • Location of mold vents
  • Mold temperature
  • Melt temperature

A quick, cost effective mold flow analysis on a part design with the chosen material and gate locations can give an accurate prediction of how a part will mold before the tool is built. Verifying  that a part design will work with the given set of critical parameters is key. If the part does have quality issues, our analysis report will recommend ways to adjust the required parameters so that the problem is eliminated.

Plastic toys

Plastic part design without the use of mold flow analysis forces the designer to use rules of thumb, guess at, or not consider these critical parameters.  This results in a high degree of risk that the part will not mold with acceptable quality levels.  Some times pushing processing conditions to the extreme limit will yield an “acceptable” part. 

However, this will cause high levels of molded in stress, degrade the material, increase scrap rates and/or increase cooling times.  Unfortunately, molds designed without the use of mold flow analysis have to resort to these tactics of “trouble shooting”.

Other critical data that is obtained by running a part design analysis includes:

  • Location of weld lines
  • Clamp tonnage requirements
  • Injection pressures
  • Location of high shear rates
  • Location of high shear stresses

Sink Marks defects

How to prevent Sink Marks defects in advance

Sink marks defects are localized depressions in the surface of injection molded parts caused by a non uniform shrinking of the plastic during the cooling process. In cosmetically critical parts, they can be a serious problem. Sink marks are dependent on part geometry and material shrink rates. Sink marks often come as a surprise when the mold is complete.

If the sink marks defects are objectionable to the customer, the plastic mold manufacturer is often tasked with “eliminating them”. Since the mold is complete, the mold manufacturer does not have the luxury of changing the part geometry. At that point, changing the material to one with a lower shrink factor is usually not an option due to sizing issues with other parts.  At this stage of the game, the only option left to the mold company is to adjust the processing conditions to try to eliminate the sink. This usually means running the molding machine at the extremes of the process window, which can lengthen cycle times and increase the amount of molded in stresses.

sink marks defects

sink marks defects

Mostly, the best solution to solve the sink marks issue is reducing the wall thickness, since mold is made by the mold company, so will be high cost to solve this issue, to avoid this sink marks issue in advance will be the idea to prevent this issue, so mold flow analysis and DFM report (design for manufacturability) is the most important role to avoid this sink marks defects.

The part below was suffering sink marks defects beyond what was allowed by the part designer’s requirements. If the tool was built to this geometry, they would have had a serious problem. Looking at the graduated scale we can see a maximum of .004″ of sink.  It doesn’t sound like much, but .005″ is the limit on the print. To fix the issue, the two thick ribs on the underside of the part were reduced in thickness.

Mold fill time

Mold Fill time is another name for melt front advancement. Our fill time animations provide the visualization of the part cavity filling before your very eyes!  As you can see from the animation, phenomena such as race tracking, weld lines formation and air trap formation are easy to visualize. Race tracking is when the plastic flow fills the thicker section of the parts prior to filling the thinner sections.  Race tracking moves the plastic in non intuitive ways which will trap air in the tool in places that are hard to vent.  The use of the melt front advancement tool solves these problems before the tool is built avoiding the quality problems in the part.

Melt front advancement is especially useful in our Gate Optimization Analysis. When trying several gate locations, the melt front advancement helps you visualize how the changes in gate position will change the way the cavity fills.  This allows you to position weld lines so that they are either in low stress or low visibility areas of the part.  Notice  that the weld lines (red lines in image below) are formed on the bolt side of the ports where the flow meets together as it comes around the port.  This was done to place them in a less visible location on the part.

Melt front advancement is also imperative when performing a Runner Balance analysis.  The critical requirement of a runner balance is to have all of the different sized cavities complete filling at the same time.  This creates a condition were all cavities receive the same packing pressure.  This prevents a short shot in the harder to fill cavities or over packing or sticking in the easy to fill cavities.

How Can We Find A Reliable Mold Maker In China

Custom Insert Molding

Plastic Injection mold is what people call the process of filling liquid plastic into a mold and waiting for it to take shape. An injection mold maker is the machine that makes the mold for injection molding. An injection mold maker creates molds from metals, usually steel or aluminum. The process calls for precision because a mistake means a repeat of the process or the part made will not be ale to function well enough and may be substandard.

The process of plastic injection molding relies solely on the accuracy of the injection mold. If the mold maker makes a mistake in making the necessary molds needed to produce plastic product, the over all effect will be defective. The mold maker must have the precise measurements of the mold it will make in order to fully meet the standards of the manufacturer and client.

Materials Used in the Process of Plastic Injection Molding:

The usual materials used by plastic injection molding are plastic materials like polystyrene, acrylonitrile butadiene styrene, nylon, polypropylene, polyethylene and PVC. These are the liquid plastics that are usually used by injection molds to produce the plastics that they will then sell. The polystyrene material is lower in cost and in material grade. ABS is a plastic that is hardier than the previous one but not flexible. Nylon can resist mot chemical and is more flexible the previous two. Polypropylene is the plastic usually used to manufacture containers because they are tough and flexible. Plastic Injection molding is also utilized for metal works.

A Plastic injection mold maker will have to make more molds if the molds are used for metal molding. Metal molding wears out the molds more than plastic molding because the melting temperature of metals is higher than plastics. Despite this additional cost, manufacturers still utilize injection molds for metal molding because the prices of metals that are molded this way are still profitable.

Uses of Plastic Injection Mold:

Plastic Injection molding is a manufacturing technique that is used for making parts from thermoplastic materials in production. After a product is designed by an industrial designer or engineer, the models are then made by a mold maker or toolmaker from metal, usually steel or aluminum.

Plastic Injection Mold is a method of molding in which the molding material is first placed in an open, heated mold cavity. The mold is then closed with a strong top force or plug member, and pressure is put on to force the material into contact with all of the mold areas, and then proper heat and pressure are maintained until the molding material has completely cured.

If you or your company needs plastic products with specific types and dimensions, then you should turn to custom injection molding companies. These mold manufacturers have the ability to make plastic parts for specific applications – they can customize virtually all plastic components per your requirements. They can stamp your logo or messages, produce unique colours and designs and package them specifically based on what you want and need.

Choosing Mold maker in China

Most of the mold maker in China that can produce any plastic product you specify, but not all of them go the extra mile to take care of ‘finishing services’ such as decorating, assembly, labelling and packaging. Some even have a design group that can assist clients with the plastic part and mould design. From rapid prototyping and plastic mold to injection molding, ultrasonic and plastic welding and stamping, these companies can assist you every step of the way. Go for China mold manufacturers that offer these added perks – you will end up saving time, money and effort comparing others nomral mold makers .

Note that some Mold Makers in China that do not do these extras in-house – they hire sub-assemblers and finishers, but are still able to produce products at par with your standards.

Also, examine the manufacturing company’s logistics and scheduling system. They should be able to handle your delivery needs no matter how demanding they may be. You should also go for Chinese plastic injection mold companies that implement strict controls to monitor the whole custom injection molding process. They should have the latest inspection equipment at hand to allow them to match the closest tolerance and thus provide quality consistently.

Mold manufacturers in China that plant climate is also very important. They should have facilities that ensure mold cooling system control. You may contact any plastic injection mold companies in the internet directory for your custom injection molding needs.

A successful injection moulding project begins with the plan of an item, and afterward is the manufacturing of plastic injection mold. With the requirement for more limited lead time and better quality, when you work on the plastic injection molding business, every day you will face those points.

In any business, you need to speck your I’s and cross your T’s, and you can’t sum up and call a whole nation unscrupulous. As impossible as it might sound everything boils down to correspondence, all the more decisively the breakdown of correspondence.

Right off the bat, you should comprehend that top quality mold maker in China over last 20 years. Be that as it may, you need to keep a couple  standard procedures to ensure you get top quality at the right injection mold cost.

How Can We Find A Reliable Plastic Mold Maker In China

You should clearly indicate your prerequisites and just work with a plastic mold maker in China that you’ve verified appropriately.

The drawings of your mold configuration should be on point and drawn up by an expert mold designer, and there can be no any sharp corner in the mold design, because that will surely effect the mold life time once in the massive production.

For a plastic mold factory to cite half not exactly that of its closest rival for the same plastic injection mould, they need to reduce their expenses to beneath half of their rivals. This is ordinarily reflected in material choice, surface completions, material hardness, absence of accuracy crushing of mating surfaces, manufacturing process, mold design skill, and absence of close resistances in divider thickness on slight divider items.

These issues can be kept away from by the unmistakable assertion of details at the RFQ stage. The issue with getting cites from mold makers in China is that when thorough particulars are required, the value differential between quality form creators gets insignificant. The complete expense of proprietorship while reevaluating plastic injection molds ought to mirror the entirety of the expenses related with testing and eventually tolerating a mold created in an outside country, and the extra precautionary measures needed to guarantee that no specialized blunders are made as a result of language boundaries.

Despite the fact that it’s moderately simple to track down a trusted, notable mould maker in Germany, UK, Japan or the US, discovering a plastic mold maker in China deserving at least some respect isn’t just about as troublesome as you may might suspect.

Injection Molding Short

Guarantee That You Own the Mold and Any Rights for That Mold

In case you’re transporting the mold abroad, you will claim the form, yet at the same time there are regions you should be sure about with your Chinese mold makers, as complete possession, IP, and so forth Notwithstanding, in case you’re delivering with a production line in China it is basic you ensure that the plastic mold manufacturer comprehend that YOU have the mold ownership,

Initially – you need to make it clear to the mold maker/industrial facility in China can just utilize the molds for delivering your items and that they can’t create any items for an outsider utilizing your mold and plastic parts

Sign an NDA document in number one thing before start the project.

Some of Chinese mold makers have a solid impetus to keep your molds and keep unfamiliar purchasers from moving to another area or production line. In a ton of cases, the form epitomizes most or the entirety of the IP in the item.

For certain items, the inside component depends altogether on open source equipment. The outside walled in area around the system is, subsequently, the essential protectable IP for the item. The protected innovation lies completely in the molds used to fabricate the item case. The outside appearance of the nook then, at that point turns into the ID of the item, and if that appearance isn’t ensured, you will claim NOTHING at all in the IP of the item. Without that IP in the mould ensured, some of Chinese companies can duplicate the item as they see fit.

Then again, in certain items, the structure encapsulates in the mold holds the whole worth of the item.

In the event that NOBODY possesses any of the IP in the molds, they are adequately named an open source, which implies no one claims any of the IP in the molds or for the item, which is a frightening spot to be. Also, the Chinese plants have sorted this out which can make ensuring your molds very hard.

You or a believed outsider should lead a form test.

When the molds have been made they must be tried PROPERLY, reports recorded, input is given on the result, and generally significant of every one of any deficiencies or boundary flops should be amended.

To do this, the form is mounted onto satisfactorily estimated injection shaping machines, set up for an advanced injection cycle, and dispatched for a restricted creation run with every one of the boundaries of a full creation aim activity.

This permits you to investigate the apparatuses under genuine execution circumstances, calibrate its settings, and create a total report of discoveries including the focuses that need change or improvement and instrument alterations for a difficulty free activity that bears the cost of the mold a greatest life expectancy.

The last strides in testing the form can improve things significantly where the distinction in progress and disappointment is estimated in miniature millimeters, and there’s not a viable replacement for experience in such manner.

We are professional mold maker in China, we will never sell your molds and molding parts to any other third parties, we have many of the custom and build the trust to our customers, so once we work together, You will 100% trust us, we will keep your project from any other companies away so that no one have chance to cope your project, contact us to discuss about your project.
