Core Product Advantages
1. Professional Pin-point Sprue Runner Design
Equipped with precision pin-point sprue runner, which realizes automatic gate separation during ejection. It leaves no gate mark on the transparent PC lens surface, effectively avoiding light refraction defects. The tiny spot feeding ensures uniform plastic filling, reduces internal stress, and protects the optical integrity of lens shells.
2. High Hardness 1.2344 Mold Steel (HRC48-52)
The mold adopts genuine 1.2344 mold steel with high hardness and excellent temperature resistance. It effectively resists high-temperature impact and wear during long-term PC transparent material molding. Stable hardness prevents mold deformation, ensures long-term high-precision production, and greatly extends mold service life.
3. Full Polished Core & Cavity for Optical Grade Surface
Both core and cavity undergo fine mirror polishing. The ultra-smooth mold surface delivers crystal-clear PC lens shells with zero scratches, zero orange peel, and zero flow lines. Perfectly meet high-standard optical appearance and light transmission requirements for lens components.
4. Special Optimization for PC Transparent Material
The mold cooling system and flow channel are professionally optimized for PC material characteristics. It effectively eliminates common defects such as air bubbles, shrinkage marks, and silver streaks on transparent products. The molded lens shells feature uniform light transmission and stable optical performance.
5. Stable 1×2 Cavity Mass Production
Reasonable 1×2 cavity symmetrical structure ensures balanced filling and consistent product weight, size and appearance of each cavity. It improves production efficiency while maintaining ultra-high precision, ideal for large-volume manufacturing of optical lens shells.
Application Range
Widely used for producing optical spot lens shells, LED lamp lens housings, lighting transparent accessories, optical instrument transparent parts, and other high-precision transparent PC optical components.
