Production process of plastic granules:
1. Plastic crushing:is to crush waste plastic products or raw
materials and convert them into plastic granules that can be
processed by plastic granulators. First, the waste plastic products
or raw materials need to be physically decomposed, including
shearing, crushing, grinding and other operations, so that they
become smaller block or granular materials. These block or granular
materials are sent to the plastic crusher for grinding to further
reduce the particle size of the material. Finally, the plastic
granules that meet the requirements are screened out through the
sieve filtration
2. Plastic melting: Plastic granules after plastic crushing need to
be melted to make them plastic. the plastic granules are sent to
the melting chamber of the plastic granulator, and the melting
chamber is usually equipped with a heating screw, which is used to
heat the plastic granules to a molten state. Under the action of
the heating screw,plastic granules are heated and gradually melted
to form molten plastic,
3. Filtration: After the plastic is melted, the molten plastic
needs to be filtered to remove impurities and insolubles. Plastic
granulators are usually equipped with filtering devices, such as
filter screens or filter plates, which can effectively filter out
impurities, residues and other impurities in the molten
plastic,filtered molten plastic material is purer, which can
further ensure the quality of the product.
4. Extrusion: The filtered molten plastic can enter the extruder
for molding. In the extruder, the molten plastic is compressed,
heated and extruded through the die by the action of the extrusion
screw. The shape of die determines the shape of the molded plastic
product. Through the die,molten plastic material is extruded to
form continuous plastic particles or plastic products, can be cut
into particles of the required length by shearing device.
