(1) Drying and preheating of PET Plastic Shampoo Bottle raw materials: drying temperature is about 170 °C, drying time is 4h~5h, otherwise it will affect mechanical properties and transparency.
(2) Injection molding of preform (barrel temperature, injection pressure): The temperature of the barrel is about 280 °C, and it is not easy to exceed 285 °C. Otherwise, acetaldehyde is easily generated, and the pressure is kept at 0.4-0.5 MPa. The preform cooling should be fast, otherwise it will affect the transparency.
(3) Preform temperature adjustment: the temperature requirement is 95 ° C, the orientation temperature is too low, the bottle stress is white, and the temperature is too high, the bottle appears crystalline mist.
(4) Stretch blow molding: a suitable mold, control the draw ratio, control the amount of blow, hold time, and exhaust before opening the mold.
