Let's Understand The Popularity Of Blow Moulding
In the literary sense of Blow Moulding, I think the idea of air or this flow will be used in this industrial process. In general, blow molding, also known as blow molding, is a manufacturing process through which hollow plastic parts are formed. Its common technology is to first melt the plastic and shape it into a plastic tubular plastic with a hole at one end. The hot parison is then expanded using pressurized gas (usually air) and pressed against the mold cavity until the plastic cools. Now it's time to open the mold and make the part.
In fact, it is very popular in industrial production. Or to say that blow mould is a multi-billion dollar business. According to statistics, the global annual consumption of this semester in the late 1980s was about 10 billion pounds. With the development of new technologies and applications continue to expand, the demand for blow molds continue to increase. There is no doubt that the word global market is still huge.
It is widely used in a variety of industrial or technical applications such as toy wheels, car seat backs, pipe networks, surfboards, bellows, fuel tanks, flower pots, car bumpers, double walled toolboxes and cabinet panels. In general, there are three main types: extrusion, injection and stretch blow mould. For injection molding, it is commonly used to mass produce insulating glass and plastic objects. It involves injection molding a thermoplastic material into a parison and transferring the mandrel into a blow mold. In fact, the equipment machine is based on the extruder barrel and screw assembly to melt the polymer.
Commercial promotion of containers is common, such as jars and bottles. This is a method of making plastic containers from parisons that stretch in both the hoop and axial directions as the parison blows into the desired shape of the container. It has the advantages of low tooling and die costs, fast production, increased tensile strength, barrier properties and transparency as well as reduced weight stretch blow molding to produce containers from less raw material, as well as improved economy and improved bottle performance.
