Pet Bottle Preform Should Be Well Maintained

Posted by preform nicole on June 4th, 2019

 Blow-molded Pet products factories need to use some Pet Bottle Mould when making products. The quality of these PET bottle moulds has a great impact on the quality of PET. Therefore, we should do a good job of mold maintenance in normal times, so that the products produced will be better.
 One is appearance maintenance: paint shall be applied to the outside of the die blank to prevent rusting. When the die is lowered, the fixed die and the movable die shall be coated with antirust oil, and the die shall be closed tightly to prevent dust from entering the cavity.  There is also daily maintenance: all kinds of moving parts such as thimble, row position, guide pillar, guide sleeve oiling, mold surface cleaning, water transportation drain, etc.  And the last one is regular maintenance, including cleaning the exhaust slot in addition to routine maintenance, adding exhaust to the trapped gas burning black position, correcting the damaged and worn parts, etc.
 The maintenance of  Pet Bottle Preform mold is very important for products. It can be said that mold maintenance is more important than mold maintenance. The more times the mold is repaired, the shorter its service life is.
