How Precision Injection Molding Works
While the core process of injection molding remains consistent, precision injection molding involves stricter controls and enhanced machinery to meet tight tolerances.
Step-by-Step Process:
- Product Design & Prototyping
- 3D CAD software is used to create highly detailed product designs.
- Rapid prototyping (using 3D printing or soft molds) helps validate the design.
- Mold Creation
- High-grade steel or aluminum molds are crafted using CNC machining or EDM for maximum precision.
- Material Selection
- Engineering-grade plastics like PEEK, ABS, LCP, and medical-grade resins are chosen based on performance needs.
- Injection Molding Process (Using Daoben Machines)
- Plastic pellets are heated until molten.
- The molten plastic is injected into the mold under precise temperature and pressure controls.
- Daoben’s advanced control systems ensure uniform filling and avoid common defects like warping or voids.
- Cooling & Ejection
- Even cooling is critical for maintaining shape and accuracy.
- The cooled part is ejected and inspected for quality.
- Quality Control & Inspection
- Dimensional checks, stress tests, and even X-ray or CT scanning ensure the part meets strict tolerances.
