Are you looking for reliable used plastic
injection molding machines to use in the
production of plastic products in your business?
If you have been in the machine industry for
quite some time, you know that plastic injection
molding is just as relevant and important as any
other machining process. There are many things to
take into consideration when buying plastic
injection molding equipment, like shot size, tie
bar spacing, ejector stroke, platen size, and
tonnage. Shot size is the maximum amount of
plastic that the injection molding machinery is
can inject into the molding cavity during one
molding cycle. The amount is rated in ounces of
general purpose polystyrene (GPPS) for U.S.
machines, and cm3 for European and Asian
machines.

When searching for a machine to use in your
business, it is a good idea to look for one that
is capable of producing 30 to 40 greater shot
sizes than what your parts require. Clamp
tonnage or clamping pressure of an used injection
molding machine could be considered the same
concept as when you are examining press brakes.
With press brakes, tonnage capabilities are
measured by the number of tons of down force the
machine can direct towards a work piece. However,
with plastic injection molding machines, tonnage
is measured by the number of tons with which the
machine is capable of pressing together the
platens, which hold the mold cavity and form the
plastic that is injected into said cavity to
produce the desired part.

The platen is the table or tool that holds the
mold cavity. Spaced apart, the mold is inserted
and then clamped securely to the platens. After
the two platens come together and are held under
the pressure of tonnage, the plastic is heated,
injected under pressure, and then it cools
through a molding cooling cycle. Here, the
plastic takes on its hardened, final shape while
continuing to be kept in place with many tons of
pressure to retain the desired shape. For more
