MRI
Vent Plugs are hard ceramic products used to plug vent holes molded
onto complex wax pattern assemblies which assists in the de-waxing of
the mold.
MRI
Vent Plugs are designed with tapered sides to prevent pushing through
the vent hole into the de-waxed mold. All vent plugs have radius edges
to avoid emitting ceramic inclusions to the pour.
MRI
offers three standard sizes of vent plugs available without a tooling
charge. Standard tolerances of +/- 1 1/2% apply.
MATERIAL
MRI
vent plugs are molded of a high grade mullite refractory composition
tested and proven in use in investment casting applications for over
30 years.
TRACE
ELEMENT CONTROL
MRI
uses only the highest quality raw materials to control trace element
levels within industry standards. Testing and reporting of trace element
parts-per-million levels is performed by an independent laboratory.
CUSTOM
DESIGN AND MANUFACTURE
If
a standard MRI vent plug size does not fit your specific requirement,
MRI will assist in the design and manufacture of a custom vent plug
to meet your needs.
TRIAL
PACK
So
that you may inspect and test the MRI vent plug product, a free trial
pack is made available. Simply select which vent plug size(s) most closely
fits your needs and notify MRI. A trial pack will be shipped for testing
and approval.
