Advanced Manufacturing Process
Injection Molding Technology
Our injection molding process utilizes state-of-the-art equipment to produce high-precision plastic screws with consistent quality.
- 1. Material Preparation: Raw plastic pellets are dried and prepared to remove moisture, ensuring optimal processing conditions.
- 2. Melting & Injection: Plastic is heated to 200-350°C in the injection barrel, then injected into precision steel molds at pressures up to 2000 bar.
- 3. Cooling & Solidification: Molten plastic cools and solidifies in the mold cavity, taking the exact shape of the screw design.
- 4. Ejection & Finishing: The finished screw is ejected from the mold and undergoes finishing processes to remove any excess material.
