What is 2 shot injection molding 2 shot injection molding is an innovative method of producing a single molded part from 2 totally different materials or colors, some poeple cal this as double injection molding, or 2k injection molding. In this type of moulding two materials with varying properties, colors and hardness are molded together […]
The majority of plastic is manufactured using large injection-molded parts. The trend toward creating large plastic parts using this technique is increasing day by day. It started after the discovery of plastic injection molding machines in the late nineteenth century. The first injection molding machine was simple. So it was used to make plastic buttons, […]
Plastic injection molding tool making is delicate and intricate, so even a single cavity plastic injection mold can cost up to $5000. This manufacturing process involves using sophisticated tools, modern technology, and skilled mold fabricators. Plastic injection molding tools are mainly applied in the mass production of plastic products. This process uses injection mold and […]
What means brass inserts for plastic injection molding Brass inserts for plastic injection molding are small metal components that are used in injection molding process to create a wide variety of parts and products, this process we call insert molding process. These inserts are typically made from brass, a strong and durable metal that is […]
When the requirements for polymer parts go beyond 3D printing and machining, it is recommended that product engineers should turn to injection molding. Conventional injection molding entails identifying the right tooling vendor and then buying the tooling, which may take several months. It may take a long time and is very tiresome, but the cost […]
Mold Making and Plastics is injection molding process which is a simplistic and efficient manufacturing process that involves injecting heated material into a plastic injection mold to shape plastics or rubber. Currently, plastic injection molding is used in several industries such as aerospace, packaging, and injection molding toys. The injection molding and plastics industry is […]
How to Start New Electronic Product Development If you’re wondering how to start new electronic product development, read on for helpful tips and information. Here are some ways you can start your own venture and avoid costly mistakes. Most end-products require enclosures, and plastic project boxes are the easiest way to make one. If you’re […]
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 […]
What is Air Bubbles or Blisters defects Air Bubbles are molding defects that appear when gas is trapped in the melt material and injected into the cavity leaving a cosmetic defects in the plastic molding part, we also call this as gas traps issues or blisters defects. There some some reason to cause this Bubbles […]
What is Black Specks or Streaks Black or brown specks are spots of degraded plastic or dark spots that show on the injection molded part. This Black or brown specks defects will be more visible on white color or clear plastic molded parts, we also call as carbon buildup, sometime we normally think it is […]
MUD U Frame is A cost-effective approach to injection molding This MUD (Master Unit Die) Quick-Change systems was designed to reach the parallel challenges of increasing productivity and decreasing production costs. MUD Quick-Change U frame Systems are more frequently becoming a part of the operational strategies for many companies who employ lean mold manufacturing programs […]
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. […]
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 […]
Soft Mold Low Volume Plastic injection molding In line with the history of the branch, since 1999, completely different companies have been providing innovative soft mold low volume quantity injection moulding solutions to numerous high profile organizations throughout a variety of industries throughout all of the continents. Undoubtedly the addition of low volume injection moulding […]
How to avoid the Air Traps Defects As plastic fills the mold cavity, it compresses the air that is in the cavity. The pressure of the air pocket increases until the required pressure is achieved to push air out of the mold vents. If the areas where the air is trapped do not have a […]
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 […]
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 […]
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. […]
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 […]
