The major systems included are:

• Machine Pneumatic System
• Machine Hydraulic System
• Machine• Wax Seals
• Overall Machine Performance
• Machine Operations Test

A detailed POP checklist is used to identify each
function and component and is available on
request. At the completion of the service, the
customer receives a written report on all work
performed. In addition, MPI provides the customer
with recommendations for process improvements
and future maintenance procedures for their
machine(s).

The Performance Optimization Program
...It's not just replacing parts.

The goal of MPI Performance Optimization
Program (POP) is to increase your casting
throughput by optimizing machine performance
during production runs and reducing machine
downtimes. We accomplish this goal by:

Subscribers to the program confirm the
following benefits:

• Reduced machine down time
• Consistent quality wax pattern production
• Reduced number of scrap patterns
• Decreased cycle time

• Monitoring the set up and operation procedures
used in your Wax Room
• Identify and suggest how to improve procedures
that optimize throughput.
• Test and service systems
• Review machine functions andprocedures with
your operators.

The MPI Process Optimization Program is making
perfect sense for our customers and we believe
that it will make perfect sense for you.

For more information about the
MPI Process Optimization Program call
845-471-7630 or your local MPI Agent.

Here is how the Process
Optimization Program works.

A series of service visits are set up that allow you
to schedule which wax injector and personnel will
be available for a process optimization visit. The
number of wax injectors in service determines the
number of visits per year.

During each scheduled visit our service technician
inspects all MPI machines and performs a full
process optimization service on the scheduled
machine.

The service includes a comprehensive function
test of each system, inspect component wear
andreplace consumables including
filters, seals and O-rings.
