4 Cavity Jar Preform Mold | High Precision PET Jar Preform Injection Mold
Overview
Our 4-cavity jar preform mold is a high-efficiency, high-precision injection molding solution specially developed for PET/PP wide-mouth jar preform production. Designed for food cans, cosmetic jars, storage containers, and daily chemical packaging jars, this 4-cavity mold achieves balanced multi-cavity molding, stable operation, and excellent finished preform consistency. Adopting premium mold steel and advanced hot runner cooling system, it supports long-term 24-hour continuous production, effectively reducing production costs and improving molding efficiency for plastic packaging manufacturers.
Core Advantages
Stable 4-Cavity Balanced Molding: Professional cavity layout design ensures consistent material flow and pressure in each cavity. The molding tolerance is controlled within ±0.005mm, with uniform wall thickness of jar preforms, no flash, no deformation, and 100% qualified rate of finished blanks.
High-Efficiency Cooling & Fast Cycle: Optimized circulating cooling channel structure shortens the molding cycle effectively. The standard cycle time is 25–33 seconds, realizing synchronous molding of 4 preforms in one cycle, greatly improving daily production output and bringing higher economic benefits.
Durable Premium Mold Material: The mold core and cavity adopt high-quality customized mold steel, with high hardness, strong wear resistance and high temperature resistance. After precise heat treatment, the service life is long, meeting the needs of long-term mass industrial production.
Advanced Hot Runner System: Equipped with a balanced hot runner system to avoid material waste and residual material. The gate cooling effect is excellent, low crystallinity of the injection port, smooth preform surface without scratches, ensuring high transparency and beautiful appearance of jar preforms.
Easy Maintenance & Strong Compatibility: All cavity parts are interchangeable for easy disassembly, cleaning and maintenance. It is compatible with mainstream 300–350 ton injection molding machines, supporting customized preform specifications such as different calibers, weights and heights.
