Sintering process may be conducted in different atmospheres: air, inert atmosphere, Powder metallurgy,reducing atmosphere (containing Hydrogen or carbon monoxide) or in vacuum. Decrease of the porosity, caused by the sintering process, is determined by the level of the initial porosity of the "green" compact, sintering temperature and time.
Vacuum heat treatment technologies and equipment Modern, precise, energy efficient and ecological vacuum heat treatment equipment with guaranteed technology. SECO/WARWICK's experience in developing these solutions dates back to the 70s of the twentieth century, when vacuum-based heat treatment technologies emerged in the aerospace, automotive

Vacuum sintering furnace is mainly used for degreasing and sintering of powder metallurgy products, metal injection moulding products, stainless steel, cemented carbide, superalloy, high specific gravity alloy, ceramics, magnetic materials, etc. Dewaxing, pre-burning and sintering process can complete rapid cooling in the same furnace at one time.
vacuum furnace high temperature high vacuum / high temperature powder sintering vacuum oven furnace Introduction CY-V series high temperature vacuum furnace is mainly used in sintering cemented carbides, stainless steel line molding, stainless steel fiber, magnetic materials,and ceramic materials,and it also can be used in power metallurgy
Depending on the composition of powders and specifics of the sintering process of powder metallurgy parts, finished parts may have various properties. Besides, they can have similar properties to those which have undergone heat treatment. So there is no need to carry out secondary heat treatment.
PVA vacuum- and Sinter HIP (Hot Isostatic Pressing) Furnaces are generally equipped with debinding apparatus that can be used to remove pressing additives cleanly and uniformly from the carbide parts before the parts are exposed to the high temperatures involved in sintering.

201577The process of sinter hardening is an alternative to conventional post-sintering hardening or case hardening and quenching, which takes place in a separate heat-treatment furnace. Sinter hardening is conducted inside the sintering furnace itself and involves rapid cooling after sintering to transform the microstructure to martensite.
The green component goes through a series of thermal processes during Powder Metallurgy production. The key heat treatment processes are sintering, where parts become solid metal components ready for service, or sinter hardening, where parts become solid metal components and are then hardened in the same process cycle.
