Vacuum Heat-Treatment Furnaces

Guidelines for Selecting Vacuum Furnaces

Vacuum Furnaces For Creation of New Values

Some remarkable new materials have been developed and manufactured in recent years, for which the heat treatment process has gained considerable attention, specifically the high added-value and reliability offered by vacuum furnaces. The leading manufacturer of vacuum furnaces, Shimadzu Mectem utilizes experience gained from delivering over 1000 vacuum furnace systems to provide a variety of models suited for a wide range of applications.
