High quality hot runner system of well-balanced melt channel that ensures all preform have consistent weight and dimensional stability
Optimized cooling layout to support fast cycle times and save water
Innovative nozzle design of less pressure loss permits better cavity filling ability
Wear-resistant coating to mold inserts and moving part which grants longer service life
Good interchangeability of mold spare parts that allows lower maintenance cost
Adopted tapered lock design for each cavity and core that reduces eccentricity of preform to minimal level
Apart from air pin-valve gate self-locked mold of no-tail-cutting, we also manufacture molds of long-tail and short tail (self-lock) according to requirement of customer.
