The plastics utilized
everyday has the different shapes and sizes. There are two types of plastics
used for producing plastics, they are thermoplast and thermal setting plastics.
The raw plastics appear as a product to the market is with the help of plastic
injection machine. The major parts of the plastic injection machines are
injection cylinder and plastic closure mould.
The products made of plastic which are larger is dimensions are made from these
closure molds. Our molds are made from alloys of steels that are resistant to
corrosion. The closure molds have a single cavity or the multiple cavity based
on demand or requirement of the manufacturers. Our molds are designed for
thermoplast as it is well suited for the injection process. The raw materials
needed for production are reduced to granules and fed to the machine. The feeding
system can be either manual or automatic by an auto loader. But we introduce
auto loader in all upcoming machines. These granules are compressed by the
reciprocating screw and passed towards the nozzle of the injector.
During compression of
the raw material, the plastic is melted to high temperature and made to form as
semi liquid. The stationary mold and the movable mold are close together to for
the molding process. As the plastic closure mold is ready to mold plastics, the
molten plastic is injected into the mold through the nozzle. The reciprocating
screw is used for the injection process as the hydraulic pressure is applied to
it. As the injection process is completed, the mold is cooled by circulating
water around the cavities in the mold. This cooling system uses water and it is
arranged to cool the plastic. The cooling process should be moderate and
controlled to avoid blistering of molds. The ejecting pins are used to eject
the plastic products. We assure our customers that the product from our mold
are well finished and have good
structure.
