Key Features & Technical Specifications
- High Cavity Count (1×16): Maximizes output per cycle, significantly improving production efficiency for bulk orders.
- Hot Runner System: Ensures uniform melt flow, reduces material waste, and shortens cycle times compared to cold runner designs.
- S136 Steel Construction: Offers excellent corrosion resistance, high wear resistance, and superior polishability, ensuring long mold life and consistent cap surface finish.
- Optimized Cooling Design: Custom cooling channels minimize temperature variation, reducing warpage and improving dimensional stability of caps.
- Precision Needle Valve Gate: Provides clean gate vestige and improves part quality, especially for caps requiring aesthetic appearance.
- Easy Maintenance: Modular design allows quick cavity replacement and simple cleaning, reducing downtime.
