Advanced Mold Design & Manufacturing
1. 1*24 Multi-Cavity Layout for Maximum Efficiency
The 1*24 cavity design is engineered to maximize production throughput, molding 24 identical components in a single cycle. The layout is meticulously balanced to ensure uniform melt flow, pressure distribution, and cooling across all cavities, eliminating the risk of imbalance, dimensional variation, or flash common in high-cavity molds. This configuration drastically reduces per-part costs, making it ideal for large-volume OEM production.
2. Premium 1.2344 Mold Steel Construction
Built with high-grade 1.2344 hot work mold steel and heat-treated to HRC 46-48, this tooling offers exceptional resistance to wear, heat, and deformation. The steel’s high toughness prevents cracking under repeated thermal cycling, while its excellent thermal conductivity ensures consistent cooling across all cavities. This results in a long mold service life and stable production performance, even after millions of cycles.
3. Direct Submarine Gate System for Clean Parts
The direct submarine gate system is strategically designed to feed material through hidden channels, leaving no visible marks on the exterior surface of the compact components. The balanced flow path ensures fast, uniform filling of all 24 cavities, minimizing internal stress and preventing warpage or sink marks in the small, thin-walled parts. The gate design also simplifies post-processing, reducing trimming and finishing requirements.
4. VDI 24# Standard Texture Finish
All 24 mold cavities are finished to a consistent VDI 24# texture, delivering a uniform matte appearance across every molded part. This texture hides minor molding imperfections, provides a subtle non-slip surface, and meets common industrial and consumer product aesthetic standards. The uniform finish ensures batch-to-batch consistency, critical for high-volume production runs.
5. Optimized Cooling for Cycle Efficiency
The mold is equipped with a precision-engineered cooling system, with strategically placed channels tailored to the compact geometry of the components. This design ensures rapid, uniform cooling across all 24 cavities, shortening cycle times and preventing uneven shrinkage or warpage. Combined with the high-cavity layout, this cooling system maximizes production efficiency without compromising part quality.
