Durable, Reliable and Complex | Fast Production Speed | Flexible Production Process |
| Injection molding is renowned for its versatility as a conventional manufacturing technique, enabling the creation of intricate, long-lasting, and dependable components. | Once the injection mold is created, the speed of producing parts through injection molding is very fast, making it an ideal method for mass production. | Injection molding has a variety of plastics to choose from and is a flexible process that can produce parts for various industries. |
Mold Components | Description | |
| 1 | Mold base | A sturdy base that holds all the other components of the mold together. It provides support and stability to the mold. |
| 2 | Cavity plate | The cavity plate is the part of the mold that forms the shape of the final plastic product. It contains a cavity or multiple cavities that fill with molten plastic to create the desired shape. |
| 3 | Core plate | The core plate is the counterpart to the cavity plate and creates the internal shape of the plastic product. It also contains a core or multiple cores that help form the desired shape. |
| 4 | Sprue bushing | The sprue bushing is the entry point for the molten plastic into the mold. It connects the injection machine to the mold and allows the molten plastic to flow into the mold through a runner system. |
| 5 | Runner system | The runner system is a network of channels that distribute the molten plastic from the sprue bushing to the cavity. It helps control the flow and distribution of the plastic within the mold. |
| 6 | Ejector pins | Ejector pins are used to push the finished plastic product out of the mold once it has cooled and solidified. They are typically located on the core side of the mold. |
| 7 | Cooling system | The cooling system consists of cooling channels or circuits that circulate coolant, such as water, to remove heat from the mold. Proper cooling is crucial to ensure the plastic product solidifies properly and minimize cycle time. |
| 8 | Venting system | The venting system consists of small vents or channels that allow air or gases to escape from the mold during the injection process. This helps prevent air traps, voids, or other defects in the finished product. |
| 9 | Guide pins and bushings | Guide pins and bushings ensure proper alignment and movement of the mold components during the production process. They help maintain precise positioning and assist in opening and closing the mold. |
| 10 | Mold inserts and lifters | Mold inserts are additional components that can be inserted into the mold to create specific features or details in the plastic product. Lifters are used to create undercuts or features that require additional mold movement during the ejection process. |
Mold Types | Description | |
| 1 | Two-plate mold | This is the most basic type of injection mold, consisting of two plates that come together to form the mold cavity and ejector system.
|
| 2 | Three-plate mold |
Similar to the two plate mold, but with an additional plate called the runner plate that separates the mold cavity from the runner system. This allows for easier removal of the molded part and reduces cycle time.
|
| 3 | Hot runner mold |
In this type of mold, the runner system is heated, allowing for direct injection of the molten plastic into the mold cavity. This eliminates the need for a separate runner plate and reduces material waste.
|
| 4 | Cold runner mold |
In contrast to a hot runner mold, a cold runner mold has a runner system that is not heated. This can result in more material waste, as the runner system needs to be removed from the molded part after injection.
|
| 5 | Family mold |
A family mold is designed to produce multiple parts simultaneously, using multiple cavities within the mold. This is useful for high-volume production and can reduce costs.
|
| 6 | Insert mold | An insert mold allows for the insertion of pre formed components, such as metal inserts, into the mold before the injection process. This is commonly used for parts that require additional strength or functionality. |
| 7 | Overmold |
This type of mold is used to combine multiple materials or colors into a single molded part. It typically involves molding one material over another to create a finished product with enhanced aesthetics or functionality.
|
| 8 | Stack mold |
A stack mold consists of multiple mold surfaces stacked on top of each other, allowing for multiple parts to be produced in the mold at the same time. This can significantly increase production efficiency.

FINISHES
| DESCRIPTION |
| 1 | Smooth or glossy finish |
This is achieved by polishing the mold surface before injection. It results in a shiny and reflective appearance.
|
| 2 | Matte finish |
This involves using a textured mold surface or applying a matte coating to create a non-eflective surface. It can help to hide imperfections and provide a more natural appearance.
|
| 3 | Texture finish |
Different textures can be added to the mold surface, such as leather, wood grain, or stippling. These textures enhance the visual appeal and feel of the product.
|
| 4 | Color finish |
Plastic injection molded parts can be colored using various methods such as pigmentation, painting, or coating. This allows for customization and branding options.
|
| 5 | Polished finish |
Specially designed polishes and buffing methods can be used to give the part a smooth and shiny appearance.
|
| 6 | Bead blast finish |
Small glass or ceramic beads are blasted at high pressure onto the molded part's surface. This process creates a uniform, matte finish with a slightly rough texture.
|
| 7 | Laser etching or engraving |
Laser technology can be used to create intricate designs or patterns on the plastic part's surface. This can be useful for branding purposes or adding product-related information.
|
| 8 | Molded-in-texture |
The desired texture or pattern is directly added to the mold itself, resulting in a consistent and durable surface finish.
|
| 1 | High Efficiency | Plastic injection molding is a highly efficient process, allowing for the production of large quantities of parts in a relatively short amount of time. |
| 2 | Versatility |
The process of plastic injection molding can be used to produce a wide range of parts with varying sizes, shapes, and complexities.
|
| 3 | Cost-Effective |
The initial cost of tooling for plastic injection molding can be high, but the cost per part decreases as the quantity produced increases, making it a cost-effective solution for large production runs.
|
| 4 | Consistency |
The use of advanced technology and precise control systems in plastic injection molding ensures that each part produced is consistent in terms of size, shape, and quality.
|
| 5 | Reduced Waste |
The process of plastic injection molding generates minimal waste as the excess material can be recycled and reused.
