PET Plastic Injection Molding

24 Cavity Plastic Injection Pet Preform Molding

The 24-cavity PET preform injection molds adopt high-precision pin valve self locked hot runner system, suitable for mass production of mineral water, carbonated beverages, edible oil, and daily chemical packaging bottles. The mold cavities are made of high-quality S136 stainless steel and vacuum-hardened to ensure a service life of over 3 million cycles. We offer custom bottle neck sizes, such as 24/410 and 28/410, and strictly adhere to FDA food-grade standards. For low-weight products, we achieve rapid molding cycles of 8-12 seconds and focus on providing cost-effective preform mold solutions for global customers.

 

Accurate size
PET Plastic Injection Molding adopts a self-locking multi-cavity structure and high-precision guide column positioning, which significantly reduces the mold cavity offset and deformation, ensures that the preform size error is controlled within ±0.05mm, and improves the consistency and stability of the injection molded products.

 

Uniform flow
Through advanced hot runner design and a precise temperature control system, PET Plastic Injection Molding can achieve uniform flow of molten PET material, prevent material degradation and cold material accumulation, and the product yield can be stabilized at more than 98%.

 

 

Corrosion resistance
PET Plastic Injection Molding uses high-quality S136 steel, which can effectively resist the erosion of acid and other chemical components in PET materials, avoid oxidation and corrosion of the mold surface, and after 3 million consecutive injections, the corrosion damage rate is less than 1%.

 

Efficient cooling
The multi-channel cooling system reduces the temperature of the PET Plastic Injection Molding mold evenly, shortening the cooling time by 15%-20%, greatly improving production efficiency while avoiding product deformation.

• Lubricate key parts of the mold regularly, such as between the template and the tie rod, between the slider and the push plate, etc.
• During lubrication, maintenance personnel need to keep the operating environment safe and hygienic.
• Use lubricating oil and apply it evenly to the lubrication area according to the step-by-step operation of the injection molding machine.
• Clean up excess lubricating oil in time after lubrication to prevent contamination of other parts of the mold and affect the mold accuracy.
• After lubrication, the injection molding machine can control the mold to repeat the action 3 to 5 times to optimize the lubrication effect.
• According to the structure, material, and frequency of use of the mold, adjust the lubrication frequency and follow the instructions.
