Revolutionizing Earplug Manufacturing: Precision Molds for High-Qolume Production

03/12/2026

Key Features of Our Earplug Mold Technology

  1. Premium Materials for Longevity

    • Core: Made from S136 heat-treated tool steel (HRC 48-52) for superior strength and corrosion resistance, ideal for long-term silicone rubber molding.

    • Frame: Constructed with durable P20 steel, ensuring stability and longevity even under high-pressure conditions.

  2. Ultra-Precise Design

    • Cavities are engineered to accommodate 1.5–2.0% material shrinkage, guaranteeing consistent dimensions (±0.03mm tolerance) and flawless surface finish (Ra ≤ 0.4μm).

    • A TiN-coated parting surface minimizes wear and tear, while a 0.01–0.03mm venting system paired with vacuum assistance eliminates 99% of trapped air, preventing surface defects.

  3. Optimized Production Efficiency

    • A balanced cold runner system ensures uniform material distribution across all 16 cavities, reducing pressure variations (ΔP <5%) and cycle times (≤30 seconds).

    • Zone-controlled temperature regulation (±1°C accuracy) maintains optimal thermal balance for flawless part replication.

  4. Seamless Automation Integration

    • Integrated robotic systems automate part removal and tray placement, slashing manual labor costs and boosting throughput.

    • RFID-enabled real-time monitoring tracks production metrics, enabling instant quality control and data-driven optimizations.
