MPI 97 Series

Soluble Wax Melter

An Industry First!

MPI’s new soluble wax-melter is unique to the industry. It is the first melter specifically designed to melt and deliver soluble wax into a reservoir. Because of the unique properties of soluble wax, until now, there has not been an efficient way to prepare soluble wax in a traditional melter.

MPI has devised a way to melt and deliver soluble wax into the reservoir using a precision melting methodology. On-injector melting of soluble wax has been a challenge for the industry for many years. MPI listened and has developed an effective
affordable solution.


  • Specifically designed to melt soluble wax effectively and efficiently, whether flake or a slab
  • Precision melting technology allows for full melting and delivery without overheating, burning, or degrading the material

97-50 and 97-200 Wax Melters

MPI wax systems will optimize the control of your wax process from melting to pattern injection. Consistent wax patterns can only be achieved if there is a consistent supply of conditioned wax with a viscosity that is appropriate for the pattern. MPI believes that separating wax melting from wax conditioning is essential to maximizing control. That’s why MPI wax melters control two important variables – the wax melt temperature and the wax melt rate. MPI’s Wax Level Control accomplishes this by automatically and continuously replenishing the wax conditioning reservoir with small amounts of source wax. The MPI 5-zone Temperature Control System monitors wax temperature at specific locations, providing the most accurate temperature control with the highest throughput in the industry. By maintaining a set temperature through all zones, we are able to achieve extraordinary pattern-to-pattern repeatability.

The Model 97 Series Wax Melters are designed for direct melting to the wax reservoir on any injection machine. It can be supplied as a standalone unit or as an integral part of the injection machine.
