Types of plastic injection molding
There are several types of plastic injection molding processes that are used in the manufacturing industry. These include:
1. Conventional injection molding: This is the most common type of plastic injection molding process. It involves melting plastic resin pellets and injecting them into a mold cavity under high pressure. The plastic quickly cools and hardens, taking the shape of the mold cavity.
2. Insert molding: In this process, inserts such as metal components or other pre-formed parts are placed into the mold cavity before the plastic is injected. The plastic then surrounds the inserts, creating a finished part with integrated components.
3. Overmolding: Overmolding involves molding one material over another, creating a multi-material part. This process is often used to add a soft touch or provide additional functionality to a part.
4. Insert overmolding: This process combines insert molding and overmolding, allowing for the insertion of pre-formed components into the mold cavity and then molding a second material over the inserts.
5. Two-shot molding: Also known as dual-shot molding, this process involves injecting two different materials into the same mold cavity in two separate shots. This allows for the creation of multi-color or multi-material parts.
6. Gas-assisted injection molding: In this process, nitrogen gas is injected into the mold cavity through the nozzle to push the molten plastic to the extremities of the mold. This helps reduce warping, sink marks, and internal stresses in the finished part.
While there are several types of plastic injection molding processes, each has its own advantages and is suitable for specific applications. Manufacturers often choose the most appropriate process based on factors such as part design, material requirements, and production volume.

The Work Process and how to use plastic injection molding
Plastic injection molding is a manufacturing process that involves injecting molten plastic into a mold cavity. The molten plastic is then cooled and solidified to create a specific shape or part. Here is an overview of how the plastic injection molding process works:
1. Design: The first step in the plastic injection molding process is designing the mold. This involves creating a 3D model of the part that needs to be produced and designing a mold that will be able to create that part.
2. Mold fabrication: Once the mold design is finalized, it is fabricated using materials such as steel or aluminum. The mold is made with two halves, a cavity side and a core side, that will come together to form the final shape of the part.
3. Injection: The mold is mounted onto the injection molding machine, and plastic resin pellets are fed into the machine’s hopper. The pellets are heated and melted in a barrel, and then injected into the mold cavity through a nozzle. The plastic fills the mold cavity and takes on the shape of the mold.
4. Cooling and solidification: After the plastic has been injected into the mold cavity, it is cooled and allowed to solidify. The cooling process can be accelerated using cooling channels within the mold.
5. Ejection: Once the plastic has solidified, the mold is opened, and the part is ejected from the mold cavity. The part may require additional finishing processes, such as trimming or polishing, before it is ready for use.
By following these steps, manufacturers can produce high-quality plastic parts efficiently and cost-effectively using the plastic injection molding process.
