The steps involved in producing plastic bottles are as follows.
Raw Material Preparation The most widely used raw material is polyethylene terephthalate (ZWIERZAK DOMOWY) resin, which is in the form of fine particles that must be dried and dehumidified.
Cylinder feeding. The dried PET resin pellets are loaded into the cylinder of the injection moulding machine. The barrel is heated until the PET resin is molten.
Injection Moulding Molten PET resin is injected into a closed mould cavity. The mould is typically made of two pieces, the middle of which is shaped into the shape of the desired product cavity. Following injection, the bottle is cooled and formed.
Remove the finished result. After cooling and curing, the mould is opened, the plastic bottle is removed, and the cycle repeats.
Deburring Burrs on freshly injected plastic bottles may need to be physically or chemically removed.
Other Post-Processes Finally, the bottle’s surface may require decoration such as printing, painting, labeling, and so on in order to be more visually beautiful and practical.
Cały proces jest zautomatyzowany, z możliwością wyprodukowania setek, a nawet tysięcy plastikowych butelek na minutę. Jedną z najpowszechniejszych metod wytwarzania przedmiotów z tworzyw sztucznych jest formowanie wtryskowe.
