Two Plate Injection Mold

What is two plate injection mold?

Two plate injection mold (2 plate injection mold), 3 plate injection mold and all of other type of plastic injection molds are type of molds used in plastic injection molding, in 2 plate mold where two separate mold plates are used to form the mold cavity, one plate we called “A” plate or A pocket plate, which contains the cavity and it is fixing half, and normally we called this cavity side, the other plate is “B” plate (or core side/movable side), which contains core inserts which is moving half, the ejector systmes is also staying at the core side.

The plastic is injected into the mold cavity through the sprue, and then the B plate is closed against the A plate to form the part. Once the plastic has cooled and solidified, the B plate is opened and the part is ejected. This type of mold is generally used for smaller, simpler parts with minimal undercuts or complex geometries.

Advantages of the Two-Plate Mold

two plate injection mold

The beauty of the two-plate design lies in its simplicity. This translates into several advantages:

Cost-effective: With fewer parts and a straightforward design, two-plate molds are the most economical option. It makes the two plate injection mold recommended for high-volume production of parts that are less intricate.
Easy maintenance: Due to their basic design, two-plate molds are easier to maintain and repair.
Fast cycle times: The simple opening and closing mechanism allows for quicker production cycles compared to more complex molds.
Suitable for a variety of materials: They can handle a wide range of thermoplastics, making them versatile for various applications.

Disadvantages of two plate injection moulding

While two-plate molds offer numerous benefits, they also have limitations:

Gate mark aesthetics: The point where the molten plastic enters the cavity (the gate) can leave a visible mark on the final product.
Part complexity: They struggle with parts that have undercuts, deep cores, or threads. These features require additional mechanisms that increase complexity and cost.
Runner waste: The runner system attached to the molded part needs to be removed, generating plastic waste.

The Molding Process in Action

The injection molding two plate mold undergoes a precise cycle to produce plastic parts. Here’s a simplified breakdown:

Clamping: This is when the B-side and the A-side are closed securely together to apply high pressure that guarantees a perfect seal.
Injection: The molten plastic will be injected at high pressure through the designated part or the sprue into the mold cavity.
Packing and Holding: After filling the cavity, pressure will be retained to even out the shrinkage of the plastic while it cools.
Cooling: The mold is cooled with water channels to solidify the plastic part.
Mold Opening: The B-side retracts, creating a parting line where the two mold halves separate.
Ejection: Pins or other mechanisms push the finished plastic part out of the cavity.
Runner Removal: The leftover plastic from the sprue and channels (called the runner) might need to be manually removed from the part.

Difference between two plate and three plate mould

A two plate mold and a three plate mold are different types of molds used in plastic injection molding, with the main difference being the number of plates used to form the mold cavity.

Two plate molds:

Imagine a clamshell. This is the fundamental concept of a 2 plate injection mold. This is made up of two key components. First is the fixed plate or also referred to as the “A-side” and second is the moving plate or the “B-side”.

The magic happens within these two halves. The A-side houses a cavity that replicates the desired shape of the final plastic part. The B-side might have a core that forms internal features or simply acts as a counter to the cavity. These two sides come together to create a sealed enclosure where molten plastic is injected.

have two separate mold plates, the “A” plate and the “B” plate.
The A plate contains the cavity and core, and the B plate contains the ejector mechanism.
The plastic is injected into the mold cavity through the sprue, and then the B plate is closed against the A plate to form the part.
Once the plastic has cooled and solidified, the B plate is opened and the part is ejected.
This type of mold is generally used for smaller, simpler parts with minimal undercuts or complex geometries.

Three plate molds:

have three separate mold plates, the “A” plate, “B” plate and the “C” plate (or runner plate).
The A plate contains the cavity, the B plate contains the core, and the C plate contains the runner the runner pusher with ejector at cavity side (this ejector only ejecting the runner which we call runner pusher as well).
The plastic is injected into the mold cavity through the C plate (runner plate), and then the B plate is closed against the A plate to form the part.
Once the plastic has cooled and solidified, The C plate is opening to pull the runner stick with C plate and then use pusher to ejector the runner off the runner plate, then B plate is opened, and the part is ejected.
This type of mold is generally used for larger, more complex parts with undercuts or other features that cannot be formed with a two plate injection mold.

3 plate mold vs 2 plate mold

In summary, the main difference between two plate and three plate moulds is that two plate mold has the runner which is located on the A or B plate which is on the parting line layer, and ejected out by the ejector systems with part together, the three plate moulds which the runner will stick with C plate ( runner plate), and later one will be ejected by the pusher, and will be more complex and expensive than two plate mold.

Plastic Cup Mold

Behind the Scenes of Plastic Cups with Plastic Cup Mold

If you are someone who ends up throwing the plastic away as the last resort you ought to read this. If it is any consolation to you, you may not be the only person who does this though this could be true at one point.

I find it sad that people do not grasp the massive importance of these plastic cups in this contemporary society. Their contribution can be seen in the very morning coffee takeaway and the crispy iced tea while you spend good time out there.

But do you think how simple containers are produced on a large scale? The answer lies in a hidden champion: Here is the: Mold, pp plastic cup

plastic cup mold

The Molding Process: Alchemy of Plastic

That is why plastic cup molds are the real players that remain unseen. These are highly delicate pieces of metal work that create the shape of molten plastic into forms of items seen and used daily. The two most common techniques commonly used in molding of plastic cups are thermoforming and injection molding.

Thermoforming is more appropriate when it comes to disposable cups. Plastics are heated until they obtain softness and can be easily molded. The mold that is usually made of aluminum then presses it do in order to have the shape of the plastic. Another clay is then applied on it before another vacuum or compressed air is used to knock off excess material to form a perfect Cup form. This process is relatively cheaper and efficient when it comes to the manufacturing of disposable cups perhaps in large quantities.

On the other hand, the use of plastic cup injection mold provides more the requirement of solid and reusable cups. In the process, the material, usually plastic in this case is forced under pressure into a hollow mold. The plastic will then crystallize and contract to the shape of the mold that is on the produced item. This process allows for the thickening of the walls of the plastic and formation of new minute designs. This is wonderful for those cups that should technically last several washes and wears.

The Anatomy of a Plastic Cup Mold

A plastic cup mold is much more than just a hollow form. It’s a complex engineering marvel with several key components:

Cooling Channels

Channels circulating a coolant, which is often water, are embedded within the plastic cup mold. The rapid cooling allows speedy solidification of the plastic to enable faster production cycles.

Core and Cavity

These are the heart of the mold. The core shapes the inside of the cup, while the cavity forms the outside.

Ejection System

Once cooled, the cup needs to be ejected from the mold. Pins or plates push the formed cup out, making way for the next cycle.

Gating System

This intricate network of channels delivers the molten plastic into the cavity. A well-designed gating system ensures proper flow and minimizes waste.

Venting System

As the plastic cools, it traps air. Vents allow this air to escape, preventing imperfections in the final cup.

Beyond the Basics: Innovation in Molds

The world of plastic cup molds is constantly evolving. Here are a few exciting advancements:

In-Mold Labeling

Designs and logos can be directly integrated into the mold, eliminating the need for separate labels.

Multi-cavity Molds

These molds create multiple cups simultaneously, increasing production efficiency.

Stackable Cup Molds

Plastic cup molds produce cups that can be stacked easily together to save space during transport and storage.

How Many Cavities Should a Plastic Cup Mold Have?

The number of cavities in a plastic cup mold will depend on the specific application and the production volume required. In general, the more cavities a mold has, the more cups can be produced in a single cycle. A single cavity mold will produce one cup at a time, while a multi-cavity mold can produce multiple cups at once.

For high volume production, it is common to use a multi-cavity mold with 8, 16, or even 32 cavities. This allows for a high production rate and can help to keep unit costs low. For lower volume production, a single cavity mold may be sufficient.

It is important to note that a multi-cavity mold can be more complex and expensive to produce and maintain. It may also require a higher level of precision and accuracy in the injection molding process.

How to Save on Plastic Cup Unit Price Using a Plastic Cup Mold

There are several ways to save on plastic cup unit price using a plastic cup mold. One way is to choose a more efficient mold design. For example, a hot runner mold can help to reduce plastic waste and lower production costs. Another option is to use a multi-cavity mold, as this can increase production efficiency and lower unit costs.

Another way to save on unit price is to use a multiple cavities of plastic cup mold. This can help to reduce the cost of production. Additionally, it is important to keep the mold well-maintained and to monitor the injection molding process closely to ensure that it is running efficiently and producing high quality cups, check to know plastic crate mould.

Clear plastic injection molding

Creating clear plastic injection molding parts involves complex tasks that differ from those involved in injection molding with non-transparent materials. Selection of materials affects their properties, production process, and final product. Working with non-transparent materials can cover some defects to a certain extent, but for transparent injection molding, the precision of the design and manufacturing processes must be impeccable.

However, it is important to note that planning and preparation are crucial in the clear plastic injection molding process before going into the details of the materials used. This entails proper preparation of raw materials, special injection molding machine, proper calibration of equipment, proper clear plastic injection mold, and proper molding procedures, which are crucial in the production of clear plastic injection molded parts.

When practicing clear injection molding, the first criterion is the ability to see the particles. Unlike opaque plastics, clear plastics do not conceal potential molding defects. Hence, it is crucial to keep every area of the production cycle as clean as possible to achieve the best quality of the final clear plastic product. Proper storage of materials is crucial to prevent contamination and ensure high-quality raw materials.

After the production of clear plastic injection-molded products, packing plays a crucial role in protecting the clear parts from scratches or surface fogging.

Material Selection For Clear Plastic Injection Molding Process

When it comes to selecting materials for translucent and clear injection molding, several options offer distinct advantages:

Acrylic (PMMA)

This versatile material allows for the injection molding of both clear and colored products. Outdoor equipment, lighting fixtures, and decorative items widely use acrylic due to its nontoxicity, scratch resistance, and UV resistance. However, the rigidity of acrylic and its brittle nature require proper drying to avoid moisture, which affects the molding process and the final product. Go to the Acrylic Injection Molding page to learn more about PMMA molding.

High-density Polyethylene (HDPE)

An advantage of HDPE is its UV resistance and its ability to mold into translucent parts. It is more resistant to breakage than acrylic and is relatively cheaper; hence, it is suitable for use in containers, bottles, and pipes, among others. However, due to its relatively low impact strength, we do not recommend HDPE for high-pressure applications.

Polycarbonate (PC)

Polycarbonate is clear, resistant to UV light, and more resistant to impact than acrylic. Safety clothing, windows, containers, and other applications demanding high-impact strength and transparency extensively utilize polycarbonate (PC). Similar to acrylic, PC also requires drying prior to injection molding for optimal performance. Learn more about polycarbonate injection molding.

Polyetherimide (PEI)

PEI is a high-performance material that exhibits excellent resistance to UV, heat, and chemical environments. High-performance applications, such as medical instruments, automotive parts, and aerospace components, widely use it, desiring its high mechanical performance and thermal characteristics. However, due to its high cost and the requirement for specialized manufacturing processes, such as the use of steel molds, PEI is most appropriate for applications that require high performance.

Polypropylene (PP)

PP is a very useful material that is characterized by flexibility, electrical conductivity, and chemical stability. Numerous industries use it for applications such as fabrics, packaging, electronics, and chemical uses. Because of its hinge-like characteristic, PP excels in applications that demand flexibility and resilience, without the expectation of bearing any load.

Liquid Silicone Rubber (LSR)

LSR is a biocompatible material with excellent thermal, chemical, and electrical stability. Medical equipment, electrical parts, and automobile manufacturing industries widely apply it where strength and efficiency are crucial. Due to its flexibility and enhanced characteristics, LSR is well suited for applications where high-accuracy molding and high performance are required.

Optical silicone rubber (OLSR)

This is an advanced material that is used for improving the light transmission and clarity of optical parts. OLSR exhibits superior non-yielding characteristics, making it a suitable choice for outdoor fixtures and other applications subjected to extreme weather conditions. Due to its good optical transmittance stability over time, OLSR is suitable for clear optical parts where light transmission is important.

All these materials have their own benefits and challenges when it comes to clear injection molding, and they are suitable for use in different applications across various industries. To produce clear molded parts of high quality, performance, and appearance, we carefully consider and implement the choice of materials, design, and manufacturing techniques.

Polyethylene (PE)

Petroleum undergoes heat and pressure exposure to create HDPE, a type of thermoplastic. While acrylic has its advantages, HDPE has UV resistance, is incredibly versatile, and is simple to mold. Large-scale production of products like bottles, pipes, and containers commonly uses HDPE due to its advantages and relatively lower manufacturing costs.

Elastomeric Resins

TPR, an elastomeric resin, is a blend of plastic and rubber, easily processed through injection molding. TPR has uses in products such as fluid dispensers, flexible hoses, catheters, and equipment that need to have resistance to liquids such as acids. Due to its flexibility and ability to withstand tough conditions, these applications prefer TPR.

Thermoplastic Polyurethane (TPU)

Thermoplastic polyurethane (TPU) is characterized by high tensile and tear strength, softness, and elasticity. This makes TPU suitable for use in the development of products that need to have a firm handle while at the same time being comfortable to hold. Despite its higher cost compared to other resins, manufacturers widely use TPU to create parts with rubber-like attributes.

Common Issue With clear injection Injection molds

Some of the common defects that are evident in clear plastic injection molding parts and the possible solutions include the following:

Plastic parts that are transparent are vulnerable to different kinds of defects during the molding process. It is important to understand these defects and how to avoid them in order to manufacture high-quality transparent products. Here are some of the most common defects and their respective solutions:

1. Air Traps

Air pockets frequently lock into the resin during molding, a phenomenon that will be visible in the final product. This is usually a result of poor venting or low pressure during injection of the material.

Solution: By enhancing the mold design to incorporate the correct venting channels and increasing the injection pressure, we can reduce the air traps and increase the product transparency.

2. Flow Lines

Flow lines, also known as streaks, form on the surface of clear plastic parts due to variations in material flow during the injection molding process. These lines can mar the beauty of the product.

Solution: To minimize flow lines and improve the overall surface finish of the clear plastic injection molding part, adjust the injection speed, pressure, and gate design.

3. Sink Marks

Sink marks, which are tiny indentations on the plastic part’s surface, typically result from variations in the cooling rate or incorrect resin filling during the solidification process.

Solution: Reducing cooling time, controlling packing pressure, and applying proper mold temperature control measures can go a long way in reducing sink marks and enhancing the quality of the part.

4. Surface Scratches

Surface defects like scratches or marks from handling or ejecting molded parts affect the transparency and surface finish of clear injection-molded products.

Solution: Proper handling and ejection procedures, mold release agents, or surface treatments can help avoid surface scratches and ensure product clarity.

5. Haze or cloudiness.

Several factors, such as inadequate drying of the raw material, contamination, or high moisture content during the molding process, can cause misting or clouding of clear plastic injection molding components.

Solution: To avoid hazing and obtain clear, transparent parts, it is necessary to pay attention to the correct handling and storage of materials, the use of dry resins, and the correct processing conditions.

Manufacturers can produce clear plastic parts with excellent clarity and aesthetic value if they correct these defects and apply the right solution.

Surface Finishing Selection and Design Tips For Clear Injection Molds

In as much as the clarity of the plastic parts is concerned, choosing the right surface finish is very important. Manual sanding and polishing are useful for rougher designs that do not have fine details, but they are not efficient for creating clear products. If the production run is low or the prototype or project is a one-off, the SPI-A2 finish may be sufficient, particularly if surface finish is not taken into account when evaluating a prototype. We also observed that deferring the concept of surface finish to the production level could result in significant time and cost savings.

For flat or nearly flat transparent parts such as windows or lenses, the best surface finish is the resin coating. Be aware that release agents damage the part’s surface and should not be used. It is important to note that lead times and costs of surface finishing may differ depending on the project.

Several aspects should be considered when designing clear or translucent plastic injection molded parts. Maintaining constant wall thicknesses throughout the part is crucial to maintain consistency in clarity. Other considerations include designing gate runners that are wide enough and placing gates in such a way that they will accommodate the contraction process. The lack of sharp corners, especially for PC products, helps to avoid gaps and make the transitions clearer.

Furthermore, maintaining a smooth surface of the mold and proper cooling will reduce the surface defects and the decline in the clarity of the plastic in clear plastic injection molding. We suggest reading more about transparent injection molding to obtain more specific design recommendations.
