Four Processing Methods Of Plastic Bottles

Plastic bottles are widely loved by distributors and consumers because of their light weight, convenient to carry, no fear of falling, acid and alkali resistance. Plastic bottles have become an important part of life. Beverages, food, pickles and honey have been covered by the plastic bottle industry, even agricultural, veterinary and medical packaging has gradually been monopolized by plastic bottles. But do you know how plastic bottles are made?

Now let's learn about the four processing methods of plastic bottles:

1. Compression moulding is also called moulding moulding in industry. It is the first step of plastic bottle processing technology to moulding thermosetting plastics such as phenolic resin and unsaturated polyester resin.

2. Extrusion moulding, also known as extrusion moulding, is a method by which heated resin is continuously passed through the moulds by the extruder to extrude products of the desired shape. It has the advantages of extruding products of various shapes, high production efficiency, automation and continuous production. The disadvantage is that thermosetting plastics can not be widely processed by this method. And the size of products is prone to deviation.

3. Injection moulding can also be called injection moulding. Injection moulding is a method of using an injection moulding machine to inject thermoplastic melt into the mould under high pressure and then to obtain the product by cooling and curing. The advantages of injection moulding are high production speed, high efficiency, automatic operation, and the ability to shape complex parts, especially suitable for mass production. The disadvantage is that the cost of equipment and mould is high and the injection machine is not easy to clean.

4. Blow moulding is also called hollow blow moulding. It is mainly a method to blow the hot resin blank closed in the mould into hollow products by means of the pressure of compressed air. Blowing includes two methods: blown film and blown hollow products. Blow moulding is mainly used to produce film products, various bottles, barrels, pots and so on.
