Key Features & Advantages
- 4-Cavity Hot Runner Design – Boosts production output by molding four parts per cycle, reducing cycle time and per-part cost. The hot runner system eliminates runner waste, saving material and improving overall efficiency.
- Premium S136 Hardened Tool Steel – This corrosion-resistant, high-polish steel ensures excellent dimensional stability and long mold life. After heat treatment, the mold achieves hardness of 50–54 HRC, capable of producing millions of high-quality cosmetic compacts.
- High-Gloss Surface Finish – Achieve a mirror-like finish on your cosmetic compacts, enhancing the visual appeal and tactile quality of the final product. The S136 steel allows for ultra-high polishing, meeting SPI A-1 standards.
- Precision Cooling System – Optimized cooling channels minimize warpage and sink marks, ensuring uniform shrinkage and faster cycle times. This contributes to consistent part quality and reduced scrap rates.
- IATF 16949 Certified Manufacturing – Our mold-making processes adhere to the stringent automotive quality management standard, guaranteeing traceability, process control, and continuous improvement. This certification reflects our commitment to delivering reliable, defect-free molds.
- Full Customization (OEM) – We tailor every aspect of the mold to your specific product design: cavity layout, gating location, ejection system, and cooling layout. Our engineers collaborate with you from concept through final sampling.
These features translate into direct benefits for your business: higher production throughput, lower scrap rates, reduced maintenance downtime, and a premium final product that strengthens your brand in the competitive cosmetic market.
