Key Mold Design & Technical Advantages

1. 1×2 Cavity Balanced Production Structure

The 1×2 cavity design produces two identical laser housings in a single cycle, balancing production efficiency and molding stability. Symmetric runner and cooling layouts ensure uniform melt flow and cooling, eliminating dimensional variation or warpage—critical for the ergonomic shape and internal component fit of medical devices.

2. 738H Steel Construction (HRC35-40)

Balanced Toughness & Wear Resistance: 738H pre-hardened steel offers excellent impact resistance and dimensional stability, ideal for molding complex, curved medical ABS parts.
Consistent Texture Reproduction: The steel’s uniform grain structure supports stable VDI 24 texture transfer across high-volume cycles, avoiding texture degradation that would compromise the housing’s appearance and grip.
Cost-Effective Durability: Pre-hardened to HRC35-40, the mold requires no additional heat treatment, reducing lead times while maintaining long service life for medical-grade production.

3. Large Submarine Gate System

Efficient, Balanced Filling: The large submarine gate ensures fast, uniform melt flow into the mold cavity, preventing short shots, flow marks, or sink marks on the textured VDI 24 surface.
Automatic Gate Break: The hidden gate separates cleanly during ejection, leaving minimal gate residue on the part surface. This eliminates manual trimming, reducing contamination risks in medical-grade components and preserving the housing’s sterile-ready finish.
Low Shear Stress: The gate geometry minimizes shear heat buildup, protecting the medical-grade ABS material from degradation and ensuring consistent part color and biocompatibility.

4. VDI 24 Textured Cavity Finish

The mold cavity is finished to VDI 24 standard, creating a uniform matte, anti-slip texture on the housing’s outer surface. Key benefits include:

Ergonomic Grip: The texture enhances user comfort and control during medical device operation, reducing the risk of slippage.
Defect Hiding: The matte finish hides minor molding imperfections and fingerprints, maintaining a professional, clean appearance suitable for clinical environments.
Consistent Quality: The standardized texture ensures uniform surface quality across all molded parts, supporting brand and regulatory compliance.
