In daily life, we come into contact with countless styles of plastic bottles. How are the different types, specifications, and shapes produced? Maybe you have been as confused as me! ! After the editor’s understanding, I would like to share with you now that a newbie in the plastic products industry has taken a step forward
The earliest use of blow molded products was glass products, which were extruded or injection molded plastics that were in a viscoelastic state. The embryo is placed in the blow mold, and the parison is inflated by compressed air to make it close to the cavity wall. After cooling and shaping, the mold is demoulded to obtain a plastic hollow product consistent with the shape of the cavity. This is the hollow blow molding process.
Blow molding plastic products are the most widely used by everyone. Its advantages are that the mold materials are rich and the product types are rich, and large-scale, complex-shaped hollow products can be produced with high production efficiency and automation, low cost, and fast molding. Disadvantages include certain restrictions on product shape, difficulty in controlling wall thickness, and low dimensional accuracy.
In extrusion blow molding, the molten material is extruded from the extrusion device. After extruding the parison, it is placed in the blow mold for blowing. After cooling and shaping, the product is demoulded and the product is taken out. Injection blow molding, the first injection The bottomed parison is then transferred to the blow mold for blowing. After cooling and shaping, the product is demoulded and the product is taken out. Stretch blow molding uses extrusion or injection to produce the parison, which is then placed in the blow mold and axially oriented using a stretch rod. Stretching, blowing and transverse stretching, cooling and shaping, and finally demoulding to take out the product.
