Key Mold Design & Structural Advantages
1. Reliable LKM2344HH Steel Base (HRC37-43)
The entire mold core and cavity adopt authentic LKM2344HH pre-hardened steel with standardized hardness controlled at HRC 37-43. This steel grade features outstanding mechanical strength, strong pressure resistance and excellent wear resistance. It effectively avoids mold deformation, cavity scratching and flash problems during long-term PA6 injection molding. Compared with ordinary cheap mold steel, LKM2344HH greatly extends mold service life and ensures stable mass production without frequent mold maintenance.
2. 1×1 Single Cavity Independent Production Design
Designed with 1×1 single cavity structure, the mold focuses on single product precision and stability. It avoids cavity interference and unbalanced filling problems existing in multi-cavity molds. Every molded back cover part maintains uniform wall thickness, consistent size and stable structural performance. This design is perfectly suitable for medium and large batch production with strict quality requirements.
3. Large Gate Submarine Runner System
Equipped with submarine runner + large gate structure, specially optimized for PA6 nylon material with good fluidity demand. The large gate design greatly improves melt filling speed, effectively solves short shot, shrinkage and incomplete filling issues for thick back cover structures. Meanwhile, the submarine hidden gate realizes automatic gate breaking and invisible gate trace after injection, saving manual trimming cost and improving production continuity.
4. General Fine Polishing for Excellent Surface Quality
The mold cavity adopts general fine polishing technology, which provides smooth mold surface texture. The molded PA6 back cover comes with smooth surface, no mold marks, no rough texture and no obvious flow lines. It meets the conventional appearance requirements of industrial shells and electronic back covers, balancing beautiful appearance and production practicability.
Production Performance & Application Benefits
PA6 nylon material is widely used for structural parts due to its high toughness, abrasion resistance and impact resistance. This professional PA6 back cover mold is structurally optimized targeting PA6 molding characteristics. The matched large gate runner ensures sufficient melt flow and pressure holding, effectively reduces product shrinkage, warpage and deformation. With stable HRC37-43 steel hardness, the mold supports long-cycle continuous injection production with low failure rate, low maintenance cost and high yield rate.
This mold is widely applicable for equipment back covers, electronic product rear shells, household appliance back panels, and industrial plastic structural covers.
