Balanced 8-Cavity High-Yield Design
One molding cycle produces 8 complete threaded rings, effectively cutting down single-piece production cost and lifting daily output for bulk order demands. Symmetric cavity layout eliminates unbalanced melt flow to guarantee identical appearance and size for all parts.
Full Hot Runner Feeding System
Eliminates cold runner waste to save 15%~22% raw material consumption. Separate temperature adjustment for each gate prevents short shot, weld line and uneven gloss on knurled and threaded surfaces.
Precision Thread & Knurling Forming
Internal thread inserts are precision CNC machined for smooth screw assembly without burrs. External knurling texture is finely etched to deliver comfortable anti-slip grip, consistent texture depth across all molded products.
High-Efficiency Uniform Cooling Circuit
Dense, evenly arranged cooling channels wrap every mold cavity to accelerate cooling and shorten molding cycle time, while stabilizing plastic shrinkage rate to maintain tight tolerance for threaded fit.
Stable & Long-Lasting Mold Structure
Hardened guide pins and precise interlock positioning avoid mold shifting during long-term high-speed cycling. Built-in yellow compression springs support automatic ejection, no manual demolding required to realize unmanned production.
The white knurled threaded rings produced by this mold serve multiple mainstream industries:
Water purifier, filter & water pipe connecting fittings
Cosmetic, skincare bottle lock caps and sealing nuts
Small household appliance plastic connecting fasteners
Medical equipment plastic sealing ring components
Sanitary ware, shower and faucet plastic accessories
