Fast Cooling With Low Deviation Molybdenum Processor Sinter HIP
Furnace
Overview
It's mainly use for Cemented Carbide Sintering process.
Sinter HIP furnaces with fast cooling are designed to integrate the
functions of pressure de-waxing, vacuum de-waxing, vacuum
sintering, pressure sintering, partial pressure sintering, atmosphere sintering, fast cooling and
etc.
