Key Features & Technical Specifications
- Heavy-Duty Construction: Mold components are made from premium tool steel (e.g., H13, P20, 718) with heat treatment to withstand high injection pressures and repeated cycles, minimizing downtime and maintenance.
- Precision Cavity & Core Design: CNC-machined and EDM-finished cavities ensure tight tolerances (±0.01mm) for consistent cap dimensions and thread sealing performance.
- Optimized Cooling System: Conformal cooling channels reduce cycle time by up to 30%, increasing productivity while maintaining part quality.
- Customizable Runner System: Available in cold runner (standard) or hot runner (optional) to suit your material and production volume requirements.
- Multi-Cavity Options: From 1 to 8 cavities per mold, enabling high-volume output without sacrificing precision.
- Compatibility: Designed for use with standard injection molding machines (100–500 ton clamping force, depending on cavity count).
- Durable Surface Finish: Cavity surfaces are polished to Ra 0.2–0.4 μm for easy release and smooth cap appearance.
