Medium Pressure Injection Moulding Machines

injection molding machine

Fully automatic Medium Pressure Injection Moulding Machine, model GC-MPIM-3-MA, 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. The GC-MPIM-3-MA is an essential component of a complete, cost-effective, production line for complex, net-shaped components.
 
Large Moulding Machines for Large Injection Volumes

Medium Pressure Injection Moulding Machine for injection volumes up to 300 cm³. This particular machine, model GC-MPIM-3-M-AQ, is designed for aqueous consolidation systems.



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.
