48 Cavity Preform Mold

This is a 48 cavity preform mold. The bottle is designed by computer simulation Tensile test to improve the yield of blowing bottle. The thread mouth is manufactured according to International standards, and the material is imported nitriding steel, which has high hardness and Long service life. Mould materials and accessories are all high-quality raw materials with high hardness And high temperature resistance. The mould production speed is fast and the mould life is long. Each mould can produce 10 million times. It can use for a long time.

1. Replace consumable parts regularly.

No matter how thoroughly you perform daily maintenance, some parts will ultimately wear out. Therefore, locate the replacement part and ensure that your PET preform molds are always in good operating order.

Such as:

a. Verify the mold cooling system (the mold cooling channels cannot hold cooling water). To increase the cooling channel's lifespan, it needs to be cleaned to stop the mold from rusting and obstructing the canal.

b. Check hot runner valve;

c. Check the wear plate, guide pin, and guide bush;

d. Check the grounding of the hot runner heating tube.

e. Check hot runner thermocouple (to prevent abnormalities and heating);

2. Do the right lubrication maintenance.

Regularly lubricate moving parts, such as the guiding pin and bush, the cavity, core, and lip cone surface, as well as all ejection components, while the mold is still in operation.
