The temperature of the PET preform mold is precisely controlled to prevent warping. Deformation is an important factor, therefore the use of a hot runner mold is recommended. The tool temperature should be high, otherwise there will be poor surface gloss and difficulties in demolding. What are the m

PET preform mould requires high precision, the difficulty lies in the thin wall of the test tube, the concentricity of the mold is difficult, the output of the test tube is relatively large, 8 cavities, 16 cavities, 32 cavities are relatively common, so the steel material of the mold should be selec
