Fully automatic Medium Pressure Injection Moulding Machine, model GC-MPIM-3-MA, equipped with pick-up device. |
GOCERAM
Medium Pressure Injection Moulding (MPIM) machines are designed
for moulding of ceramic, metal and intermetallic (tungsten
carbide) feedstocks, primarily using wax-based binders. These table top
units are compact, flexible and service-friendly and are
constructed for durable large scale, fully automatic production,
as well as for short series in semi-automatic or manual mode.
There are two injection directions, either horizontal or vertical,
of which the latter is suitable for the manufacture of prototypes,
preceding large volume output in horizontal mode. The GC-MPIM-3-MA
is an essential component of a complete, cost-effective, production
line for complex, net-shaped components. |

CIModule® |
 |
|
The GC-MPIM-3-MA is equipped with a unique Compact Injection
moulding Module - CIModule - in which the feedstock
is kept, see photo. It consists of the pressure chamber,
the injection piston and the hopper - all made of stainless
steel. The module is designed to be easy to clean and
rapidly interchangeable (requires about 5 min). The
versatile CIModule can, in addition- to the wax system,
be used for other binder concepts, for instance gel-casting
or freeze forming. |

Modes of operation - pneumatic or with a servo-motor
In
the standard version of the MPIM Machines, GC-MPIM-3-MA, the feedstock
is injected into the mould by a pneumatic piston - a
simple, reliable and robust system.
As an option, the
machines can be equipped with an electrical servo-motor
with digital, high precision motion control unit including
a supervising PC or a durable terminal - model designation GC-MPIM-3-MA-X. In this case injections with different
rate profiles can be programmed in order to perfectly adapt
the injection cycle to a certain mould and/or feedstock. See an example of a profile below.
Tooling
Because of the moderate
injection pressure, the tooling cost is low. The moulds
can be produced of not only steel but also of more easy-to-machine
metals such as aluminium and brass. In addition even
plastics, preferably with heat conductive additives,
can be used.
