MPI 75-300

One Machine for all Molds!

MPI’s jewelry injection equipment sets the standard for the jewelry industry. Utilizing high-pressure metal mold technology, our new rubber and metal mold wax injector has significant advantages over other injection techniques, which dramatically increase both the quality and quantity of your wax patterns. We offer 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 will meet your needs and optimize your throughput.

... The only wax injector designed to run rubber and metal molds.

The MPI 75-300 can be used as a low pressure rubber mold injector, or as a medium pressure metal mold injector.

The vacuum evacuation of the rubber mold is consistent every time.

The entire mold is placed in the evacuation chamber. No need to rely on a perfect nozzle to mold vacuum seal. Now rubber molds can be designed with vacuum vents never before possible with nozzle evacuation systems.

The MPI 75-300 is designed to dramatically increase both the quality and quantity of your wax patterns. Its innovative design and high-performance are the result of advanced technology, developed by MPI incorporated, the leader in wax injection technology for over 30 years.

The MPI 75-300 advanced operating system sets the standard to the jewelry industry. We are confident our new rubber and metal mold wax injector will improve your bottom line.

Mold to nozzle alignment, vertical and horizontal, is quick and accurate.

Vertical mold alignment using height adapter platens, allowing for nozzle height adjustment from .5″ to 1.25″ (12.7 – 31.8mm) in increments of .125″ (3.18mm).
Custom height platens are available.

Molds are aligned horizontally by guide strip on top of the platen.

Efficient run Cycles:

  • Operator selects vacuum or non-vacuum modes.
  • Vacuum mode cycle starts automatically when the chamber door is closed.
  • Non-vacuum cycle is started when chamber door is closed and start button is pressed.
  • Automatic cycle of clamp, inject and unclamp, with or without vacuum.
  • Controls for wax temperature at reservoir and nozzle, injection pressure, wax flow control, cycle time, clamp pressure and selection of a vacuum or non-vacuum cycle are upfront, easy to read and simple to adjust.

Built in removable wax melter means much better patterns and shorter cycle times.

The MPI 75-300 wax reservoir top loading wax melter, eliminates the need for pre-melting wax or waiting to come to operating temperature.

The wax melter is easily removable for wax change over and clean out.

A wax reservoir drain is supplied standard.

Features:

  • Compact self-contained unit
  • User-friendly front control panel
  • Precise control of wax temperature, pressure, flow and time
  • Controls both wax resevoir and nozzle temperatures
  • Quick and accurate mold positioning using adjustable die guide strip
  • Nozzle extends at start of cycle to positively seal with mold
  • Wax injection pressure is adjustable from 0 – 300 PSI (0 – 21 bar)
  • Mold clamp force is adjustable up to 120 lbs (55 kg) of pressure
  • Built in vacuum chamber
