While going for the process
of injection molding, it is important that the machine should be chosen carefully
because unless and until the machine works properly, you won’t be able to get the
right shapes of the plastics. The obvious thing is that you can always talk to
the supplier of the machine regarding it, but nevertheless, there are certain
guidelines that can help you in knowing the selection criterion of the Plastic
Injection Molding machine. Primarily,
there are three diverse aspects that should be focused upon and these are:
·
The mold
·
The clamping
unit
·
The injection
unit
The Mold
It is very important
to ensure that the mold fits in nicely and perfectly to the clamping area. Height
as well as depth of this mold should be accommodated nicely with clamp stroke. There
are certain other specifications that should be kept in mind before you analyze
the mold.
The Clamping Unit
It is very important
that during the phase of injection, the clamping unit should be firm enough to
keep the mold shut tightly. You can know the exact dimensions of the clamping unit
from your supplier, who will also tell you about certain other things that should
be observed about the clamping unit.
The Injection Unit
The role of this component
is to provide shot weight. The shot weight in all should never be more than 90%
of total injection capability of the machine.
These are the three
main components of Plastic Injection
Molding machine that should be checked primarily, though other components
should also be checked.
