High dimensional stability: Resists deformation under PC’s high-temperature molding conditions
Uniform surface quality: Consistent hardness across the cavity ensures even texture finish
Low maintenance requirements: Pre-hardened steel eliminates the need for post-machining heat treatment, reducing risk of warpage
Consistent color and texture: Optimized surface treatment ensures no uneven gloss or color variation
Premium appearance: Matte finish hides minor molding defects while providing a sleek, professional look
Scratch resistance: Textured surface improves resistance to light scratches during assembly and use
Flow path optimization: Ensures uniform melt distribution in the thin-wall upper cover design
Shrinkage control: Precisely compensated shrinkage rates eliminate warpage and dimensional deviation
Stress reduction: Optimized cooling channels minimize internal stress, preventing post-molding deformation
Focused precision: Dedicated tooling ensures the highest possible dimensional accuracy for the upper cover
Flexible process control: Parameters can be fine-tuned without affecting other cavities, ensuring perfect surface quality
Cost-effective for medium volumes: Avoids over-engineering while maintaining quality standards
Excellent polishability: Can achieve consistent matte or semi-gloss finishes required for exterior parts
Uniform hardness: Pre-hardened to HRC35-40 throughout the block, ensuring consistent performance
Good wear resistance: Withstands repeated PC molding cycles without significant surface degradation
Low risk of defects: Pre-hardened steel reduces the chance of post-treatment warpage or cracking
Color consistency: Optimized flow paths prevent color streaking in the deep navy resin
Surface durability: Matte texture reduces the visibility of fingerprints and minor scratches
Assembly compatibility: Dimensional stability ensures a perfect fit with mating components
Consumer electronic devices (routers, modems, smart home hubs)
Small home appliances (kitchen gadgets, personal care devices)
Communication equipment
Industrial control panels
Surface finish adjustment: Modify texture depth for different matte/satin/gloss levels
Runner system upgrade: Convert to hot runner for reduced material waste and faster cycles
Steel grade upgrade: Switch to higher-hardness steels (e.g., 1.2344) for extended mold life
Dimensional adjustments: Fine-tune cavity dimensions for precise assembly tolerances
CMM dimensional verification: Confirms cavity dimensions are within ±0.03mm tolerance
Surface texture inspection: Optical checks ensure uniform matte finish across the entire cavity
Trial molding with PC resin: Verifies melt flow, shrinkage control, and color consistency
Hardness testing: Confirms uniform HRC35-40 hardness across critical mold surfaces
