Plastic Bottle Mould in the heat treatment occurred during the deformation of the prevention

Under the premise of ensuring the hardness of the Plastic Bottle Mould , as far as possible the use of pre-cooling, graded cooling quenching or warm quenching process.
2, Chang Ping heat treatment recommendations. For precision and complicated molds, if the conditions permit, nitriding heat treatment plant recommends the use of vacuum quenching and quenching after cryogenic treatment.
3, for some sophisticated molds can be pre-heat treatment, aging heat treatment, tempering nitriding heat treatment to control the accuracy of the mold.
4, nitriding heat treatment plant in the repair of mold trachoma, porosity, wear and other defects, the choice of cold welding and other thermal effects of small repair equipment to avoid the process of repairing the deformation.
5, die structure design to be reasonable, not too thin thickness, the shape should be symmetrical, the experts said that deformation of larger molds to master the deformation laws, allowance for processing allowances, for large, complex and complex molds can be combined structure.
6, Precise and complex PET Mould should be pre-nitrocarburized to eliminate the residual stress generated in the machining process.
