Furnace Muffle: Determine the True Costs

Do you ever wonder what the true cost is for your traditional furnace muffle? Is saving some money upfront really saving you overall?

Check out our comparison below and see for yourself.

A traditional straight-walled rectangular muffle for a sintering furnace made of 330 Alloy would have a service life of about 12-14 months operating at 1120⁰C (2048°F).

However, an Alloy Engineering muffle made out of 330 Alloy using deep corrugations and welded with inert gas shield arc would have a service life of 24 months under the same conditions.

Using the assumption that it takes one week to replace a furnace muffle, you have 4 furnaces with one muffle per furnace and the furnace normally operates at $400 (USD) profit, see the below comparisons of the 4 muffles over a 24 month period:
