MPI 35 Series 4 Post

4 Post Wax Injector

MPI offers the most sophisticated wax injection systems in the industry, generating higher casting yields, more patterns per hour and increased productivity and throughput.  Our Smart Process Control provides real time monitoring and control of all injection parameters and feature an intuitive Windows based touch screen. Our wax conditioning technology maintains a constant wax viscosity which produces consistent wax patterns and our quick change technology allows you to change dies in just 60 seconds – minimizing transition times and maximizing throughput. All MPI systems come with our world class technical support and training.

  • The MPI 35 is an open 4-Post designed to accommodate all die designs and sizes. Operator controls are ergonomically located for efficient operation. The MPI 35 is available in three sizes with clamping forces of 100, 200, and 300 tons (91, 181, and 272 tons metric).
  • The unit is fitted with an impressive list of standard features and a wide range of options are available. Our engineering support staff is prepared to help determine the configuration that meets your needs and will optimize your throughput.

Tee Slots (optional)

Tee slots on each platen provide full coverage die clamping and eliminate stripped threads.

Hydraulic Pattern Ejection (optional)

Controlled pattern removal from the lower stationary platen.

Two Shuttle Tables (optional)

Increase machine utilization by injecting one die while performing die disassembly and pattern removal on a second die.

Jib Crane (optional)

The unique combination of Jib Crane and Hydraulic Shuttle Table allow quick, safe pattern removal and die changeovers by a single operator.

Paste Wax

Accurately conditions wax to any viscosity from liquid to paste, providing consistency from pattern to pattern regardless of the input wax temperature.


Three Axis Nozzle Positioning

Total alignment

Motor driven x-y-z nozzle positioning allows for die designs with the most direct wax flow path.
