 Product Overview

This 16-cavity high-efficiency injection mould is purpose-built for the mass production of precision PC (Polycarbonate) annular parts featuring integrated lateral snap-fit locating structures. Designed to overcome the common challenges of multi-cavity imbalance, cosmetic surface finishing, and undercut release, this mould solution delivers exceptional part consistency, cycle efficiency, and operational longevity for demanding automotive, electronics, and consumer goods applications.


 Key Technical Features

Feature Specification / Benefit
Multi-Cavity Architecture 16 cavities with a naturally balanced H-type runner system. Ensures identical melt flow paths and pressure distribution across all cavities, minimizing warpage and dimensional deviations (tolerance within ±0.02mm).
Partial Polishing Strategy Zone-specific surface finishing: High-gloss SPI A1 (Ra 12-25nm) on cosmetic appearance areas for premium optical clarity, while maintaining a controlled Ra 0.4~0.8µm on selected flow-critical surfaces to optimize PC melt mobility and reduce injection pressure.
Lateral Snap-Fit Locating System Robust slider (side-core-pulling) mechanism driven by precision angle pins. Reliably releases internal/external undercuts of the snap-fit features with zero drag marks, ensuring secure and consistent part assembly in downstream operations.
Advanced Cooling Network Conformal cooling channels independently routed for each cavity cluster, achieving uniform temperature distribution (ΔT ≤ 3°C) . Reduces cycle time by 15–20% while eliminating sink marks and internal stresses.
High-Performance Tool Steel Manufactured from premium imported S136 / H13 steel with a PVD/DLC anti-wear coating. Offers exceptional corrosion resistance, wear resistance, and a service life exceeding 2 million shots for PC materials.

What Makes This Mould Unique?

  1. Designed for PC’s Special Rheology
    PC is known for its high viscosity and sensitivity to shear rate. Our mould incorporates computer-aided engineering (CAE) flow simulation to optimize gate locations (pin-point or edge gates) and runner diameters, preventing flow hesitation, burn marks, and jetting defects common in thin-walled annular geometries.

  2. Defect-Free Undercut Release
    The lateral snap-fit areas are often the weakest point during demolding. Our patented slider design features an angled ejection assist, which ensures a smooth, frictionless release sequence—protecting the fine locating ribs from fracture or deformation even after hundreds of thousands of cycles.

  3. Localized Polish for Functional & Aesthetic Excellence
    Instead of applying uniform mirror finishing (which can actually hinder PC flow), our dual-polish strategy improves both moldability and aesthetics. The result: a high-gloss outer ring with crystal-clear transparency, combined with a matte-functional finish at the snap-fit contact points for improved grip and wear resistance.

  4. Smart Maintenance & Interchangeability
    All core pins and cavity inserts are modular and interchangeable, allowing for quick repair or replacement without dismantling the entire mould base—reducing downtime and maintenance costs significantly.
