• Mold Type: Precision hot runner injection mold (for circular plastic parts)
• Cavity Number: 4 cavities
• Design Life: 1,000,000 cycles
• Mold Steel: Premium tool steel (H13 / 1.2344 / S136 / 718H) selected based on product material and finish requirements, heat-treated to HRC 48–52 for exceptional wear resistance, fatigue strength, and dimensional stability. Hot runner components use corrosion-resistant, high-hardness steels (e.g., S136) to match the mold’s long lifespan.
• Structure Features: Modular hot runner system, precision cooling channels, and reliable ejection mechanism to optimize production efficiency and minimize maintenance.

Why Choose Our Company?

1. Expertise in High-Life Hot Runner Molds: We specialize in designing and manufacturing 1,000,000-cycle hot runner molds, with deep experience in packaging and consumer goods tooling. Our engineering team optimizes every detail—from hot runner layout to cooling design—to ensure stable, long-term production.
2. Premium Material & Precision Manufacturing: We use only certified, high-grade mold steels and hot runner components from reputable suppliers. Our in-house CNC, EDM, and grinding facilities deliver micron-level precision, guaranteeing consistent part quality across all 4 cavities.
3. Optimized for High-Volume Production: The 4-cavity hot runner design balances production efficiency and tooling cost, making it ideal for mass production of circular components. Short cycle times and minimal downtime reduce your per-unit cost significantly.
4. Rigorous Quality Control: Every mold undergoes flow simulation, FMEA analysis, and full trial molding before delivery. We inspect critical dimensions, hot runner performance, and ejection functionality to ensure zero defects and immediate production readiness.
5. Full Lifecycle Support: From mold design to after-sales maintenance and spare parts supply, we provide end-to-end service. Our team ensures quick response to maintenance requests, maximizing your production uptime and extending the mold’s service life.
