China plastic molding can be widely categorized into two main types which include thermosets and thermoplastics. The main difference between the two types of plastic molding is regarding the formed polymers and another one is that thermoplastics are moldable while the other one is not. The most significant difference is that the thermoplastics follow one dimensional chain while the other one follows three dimensional chains of polymers. The polymers of thermoplastics can be easily reshaped after melting but the polymers of the thermostats retain the similar shape. A series of molding processes are followed in both the cases where some are similar for both while others are highly specific to any one of the type.
The extrusion process is the first step of the plastic molding process in China where the raw plastic beads or pellets are kept into a revolving chamber by means of hopper for the melting process. The same principle is also followed by the injection process of the molding procedure. The melted product from the revolving chamber is then transferred into a die for providing final shape to the finished products.
The method of blow molding is usually used for the effective and quick cooling of the liquefied plastic for the conversion of the liquefied material into a solid form. The compression method is useful for both the types of plastic molding in China. It basically contributes in the reshaping of the molding plastic to a new form. Thermoforming process is the most efficient method of providing desirable shapes and sizes to the final molded products.
