Surface Finish Ra≤0.2μm (matte/glossy optional); mirror polish (Ra≤0.1μm) available
Mold Material Core/cavity: S136/H13 medical-grade steel; Base plate: P20 steel
Heat Treatment Vacuum quenching + tempering (HRC 52–56); nitriding for wear resistance
Compatibility PP, PE, ABS, PC, PVC, TPE, and medical-grade biocompatible plastics
Automation Integration Robot-friendly design (ejector pin synchronization + part separation)

Key Advantages for Mass Production

  1. Ultra-High Output: Multi-cavity design (max 64 cavities) + high-speed molding reduces unit cost by 20–40% vs. single-cavity molds.

  2. Stable Precision: Uniform cavity cooling channels (3D-printed conformal cooling optional) + hot runner system (DME/Husky) ensure consistent part quality across all cavities.

  3. Fast Cycle Times: Optimized mold opening/closing mechanism + shortened cooling time (via conformal cooling) cut cycle time by 30–50% vs. traditional multi-cavity molds.

  4. Durability for Long Runs: Wear-resistant mold steel + anti-corrosion treatment (chromium plating) support 1–3 million shots without compromising precision.

  5. Automation Ready: Integrated part ejection + separation design enables seamless connection with robots for automatic sorting, inspection, and packaging.

Critical Mold Design & Manufacturing Features

  • Hot Runner System: Balanced flow distribution (pressure drop ≤5%) to ensure uniform plastic filling across all cavities; reduces material waste by 10–15%.

  • Conformal Cooling: 3D-printed cooling channels (for complex parts) follow cavity contours, reducing cooling time by 40% and minimizing warpage.

  • Precision Alignment: Guide pins with ±0.002 mm tolerance + wear-resistant bushings ensure cavity alignment during high-speed cycles.

  • Quick Mold Change (QMC): Standardized clamping system enables mold change in 30 minutes or less, improving production flexibility.

Application Scenarios

  • Disposable Medical Supplies: Syringe barrels, infusion set components, respiratory mask parts (ISO 13485/FDA compliant).

  • Consumer Electronics: Phone cases, charger housings, earbud shells (high-volume, consistent quality).

  • Automotive Parts: Interior trim clips, sensor housings, connector components (fast production for assembly lines).

  • Household Goods: Plastic utensils, container lids, small appliance parts (cost-effective mass production).

Quality Assurance for Mass Production

  1. Cavity Uniformity Test: 100% dimensional inspection of parts from each cavity (CMM/optical measuring instrument) to ensure consistency.

  2. Process Validation: FMEA analysis + mold flow simulation (Moldflow) to optimize filling, cooling, and ejection; stable process capability (CPK ≥1.33).

  3. Traceability: Mold serial number + batch tracking; material lot records linked to production parameters.

Customization Options

  • Cavity number optimization based on part size (minimum part size: ≥5×5×1 mm).

  • Conformal cooling design for complex geometries.

  • Medical-grade customization (ISO 13485 compliance, biocompatible materials).
