Hot Runner Preform Mold

This product is a high-precision hot runner preform mold conforming to the US SPI Class 101 standard, specifically designed for high-volume, high-cycle PET preform injection molding. It completely solves problems such as hot runner leakage, uneven preform wall thickness (eccentricity), and frequent downtime for maintenance in ultra-high-speed production.

Description

Product Introduction

Product Advantages

SPI Class 101 Mold Life Rating

Using Swedish Uddeholm S136 stainless steel (vacuum hardened HRC48-52), significantly extending mold lifespan.

Coaxiality ≤0.05mm

Double taper precision positioning locks the cavity and core, strictly controlling preform wall thickness tolerance and completely eliminating the risk of bottle explosion due to uneven wall thickness.

Conformable Cooling Water Channel

Embedded conformal cooling water channel combined with high thermal conductivity beryllium copper inserts reduces the overall injection cycle to 8-15 seconds, significantly increasing single-machine capacity.

100% Zero Gate Waste

Pneumatic/hydraulic needle valve sequential control ensures simultaneous filling of all cavities with uniform shear heat, eliminating runner solidification and achieving 100% raw material utilization.
