Core Advantages
1. 1×6 Multi-Cavity High Production Efficiency
6-cavity symmetrical balanced layout greatly improves output capacity. Each cavity runs synchronously with consistent temperature, pressure and filling speed, ensuring identical thread precision, size and surface quality for every PA screw. Perfect for large-volume fastener mass production.
2. Professional Submarine Hidden Gate Design
Adopts submarine hidden gate structure. The gate breaks automatically during ejection, leaving no gate mark on the screw surface. It realizes one-time finished products without manual trimming, greatly saving post-processing cost and keeping the thread and appearance completely flawless.
3. Large Sprue Runner for PA Material Stability
Large sprue and optimized runner system provide stable and fast melt flow for PA nylon material. It effectively prevents short shots, material shortage and unstable filling, solves common PA molding defects, and ensures full and complete thread forming.
4. 1.2344 HRC48-52 High Hardness Mold Steel
Made of high-quality 1.2344 hot work mold steel with HRC 48-52 high hardness. It features excellent wear resistance, high temperature resistance and deformation resistance. Especially suitable for long-term continuous production of PA nylon and glass-filled PA materials, greatly extending mold life and maintaining stable thread precision.
5. Fully Polished Core & Cavity for Precise Thread
Both core and cavity are finely polished to ensure ultra-smooth mold surface. The precise thread insert processing guarantees standard through thread size, tight tolerance, no burrs, no tooth damage, making the molded PA screws reach industrial assembly standard directly.
6. Stable Through-Screw Molding Performance
The mold is professionally optimized for through-thread screw structure. It solves problems such as thread incomplete, shrinkage, warpage and rough surface, ensuring high-precision, high-strength and high-consistency plastic screw fasteners.
Application Scope
Suitable for mass production of PA nylon through screws, plastic fasteners, plastic bolts, structural screw parts used in electronics, electrical appliances, furniture, automobiles and daily hardware industries.
