Vacuum sintering is the process of forming a single mass from multiple components, typically powder, by heat and/or pressure without melting the base materials to the point of liquefaction. Sintering process is required for many different parts and applications, including powder metallurgy, metal injection molding (MIM) and 3D printing components of various types or beading applications including abrasives. In This application it is very important to have clean atmosphere for stronger bonding. Hence Vacuum Technology in Sintering is the Best Technology which yields better results with Brighter Finish. As the Sintering temperatures are usually higher than other heat treatments its ideal to have a equipment with precise temperature control which Lakshmi Vacuum have pioneered in.
