Blow molding is a common method for manufacturing hollow blow molded products. The main products are cylindrical films and hollow containers. PET Blowing Machine can plasticize pre-formed products by heating and then enter the mold for blow molding. This method is mainly used for high-speed and high-volume production of PET bottles and BOPP bottles, that is, the two-step process; blow molding can also be used with The injection molding process is combined into an injection, stretch, and blower, which is also a common method for producing containers in PET; the blow molding process can also be combined with the extrusion process, and the adaptation of extrusion blow molding equipment is wider, and the products that can be produced are also More abundant, the products include multilayer composite films and various polyolefin hollow containers, which are widely used in food, medicine and cosmetics industries.
According to the method of making parisons, blow molding can be divided into extrusion blow molding and injection blow molding. Newly developed multilayer blow molding and stretch blow molding.
The energy saving of the blow molding machine can be divided into two parts: one is the power part, and the other is the heating part.
Energy saving in the power part: Most inverters are used. The energy-saving method is to save the residual energy consumption of the motor. For example, the actual power of the motor is 50Hz, but you only need 30Hz in production. Wasted, the frequency converter is to change the power output of the motor to achieve the effect of energy saving.
