YIXUN mold
8480419090
Mold Base: 4Cr13 Stainless Steel – Corrosion-resistant, rigid, and supports 1,000,000+ injection cycles; withstands the abrasive nature of PP (even glass fiber-reinforced PP) during long production runs.
Cavity & Core: ASSAB S136 ESR Steel – Vacuum heat-treated to HRC 52-55, offering exceptional wear resistance and dimensional stability; polished to Ra 0.015μm for smooth vent cap surfaces (avoids PP residue buildup and ensures easy ejection).
Hot Runner Components: High-precision copper heaters + beryllium copper nozzles – Ensures uniform temperature control (190-210℃, optimized for PP) and prevents material solidification in flow channels, reducing waste by 20% compared to cold runner molds.
PP Material Optimization: Molded with widened flow channels and rounded corners – Addresses PP’s low viscosity and fast cooling characteristics, ensuring full filling of micro-vent structures without short shots or flow marks.
| Cavity Configuration | Daily Output (8-Hour Shift) | Unit Cost Reduction | Key Benefit |
| 1×8 Cavity (Hot Runner) | 30,000-35,000 vent caps | 30-40% vs. 1-cavity molds | Ultra-high efficiency for mass production; lower per-unit tooling cost. |
Vent Structure Precision: Micro-machined channels (0.2-0.8mm diameter) or slotted vents with tolerance ±0.02mm – Ensures consistent air flow (tested to 5-15 L/min airflow rate) while blocking particles ≥50μm.
Hot Runner System: Valve-gate hot runner (8 independent nozzles) – Enables synchronized filling of all 8 cavities, eliminating pressure imbalances and ensuring uniform wall thickness (1.0-1.5mm) across all parts.
Cooling System: 360° spiral cooling channels + dedicated cooling for vent structures – Reduces cycle time to 18-22 seconds per 8-piece batch and prevents PP shrinkage/warping (dimensional accuracy ±0.03mm).
Sealing & Fit: Precision-machined outer diameter and snap-fit grooves – Ensures tight, leak-proof installation with host products (compatible with automotive housings, packaging containers, and industrial enclosures).
Ejection System: Synchronized soft-eject pins with Teflon coating – Prevents scratches on PP surfaces and enables seamless robotic part removal (compatible with automated production lines).
Material Safety & Standards: Mold compatible with food-grade PP (FDA 21 CFR Part 177) and industrial-grade PP (ISO 10993); meets automotive (IATF 16949) and industrial packaging (ASTM D4101) standards.
Strict QC Protocols:
72-hour continuous cycle testing with PP materials to verify hot runner stability and part consistency.
100% dimensional inspection via CMM (focus on vent hole diameter, outer diameter, and snap-fit dimensions).
Airflow and particle-blocking testing for sample vent caps (test reports provided upon request).
Durability Testing: Molded PP vent caps pass 5,000+ insertion/removal cycles and 1000-hour environmental testing (temperature: -40~80℃; humidity: 0-95%) without structural failure.
