Injection Molding 

About Injection Molding

Injection molding is a molding method that combines injection and molding. At a certain temperature, plastic materials are completely melted through screw mixing, then injected into the mold cavity under high pressure. After cooling and solidification, the molded product is obtained. This method is suitable for the mass production of complex-shaped parts and is one of the important processing methods.

Advantages of injection molding are fast production speed, high efficiency, precise product dimensions, easy product updates, and the ability to mold complex shapes. Injection molding is suitable for mass production and molding processing of complex-shaped products.

Injection Molding Process

1. Mold preparation (Davin can assist customers with design and production, or customers can provide their own)

2. Raw material pre-processing (such as drying and heating, to ensure optimal flowability and molding performance during the injection molding process)

3. Injection molding (the injection molding machine heats the plastic pellets to a sufficient temperature, making them soft and flowable. Once the appropriate state is reached, pressure is applied to inject the molten plastic into the mold.)

4. Cooling and solidification (cooling time depends on the type of plastic used and the size of the product)

5. Mold opening and part removal (once the plastic has cooled and solidified, the mold opens, and the formed plastic parts are removed)

6. Post-processing (formed parts may require some post-processing steps, such as cleaning, painting, or assembly, to meet the requirements of the final product)
