CNC Machining Polishing Injection Mold Ejector Pins Plastic Mold Tool
Precision-engineered mold core pins for plastic injection molding applications, specifically designed for medical industry fluid sampling pipettes. These components create internal surfaces in molded products with exceptional accuracy and durability.
Mold Core Pin Description
Mold Core Pins are extended male components that form internal surfaces in plastic injection molds. Manufactured from high-quality tool steels, these pins are engineered to withstand misalignment during molding processes while maintaining structural integrity.
Critical manufacturing considerations include:
- Pinch grinding to prevent deflection during grinding cycles
- Near-perfect Total Indicator Runout (TIR)
- Temperature-controlled grinding to preserve metal characteristics and prevent warping
