  Metal Injection Molding (MIM)  has revolutionized the manufacturing industry by enabling the production of complex metallurgy products. One of the crucial steps in the metal injection moulding process is pressureless sintering, which enhances the density and strength of the final product. This blog post will delve into pressureless metal sintering, exploring its history, definition, operation steps, advantages, and applications. By the end, you'll understand why pressureless sintering is a game-changer in metallurgy products and why Neway is your ideal partner. Pressureless Sintering Overview  Pressureless sintering is vital in MIM casting, transforming compacted metal powder into a solid, fully dense product. Unlike other  hot pressing sintering  methods, pressureless sintering does not rely on external pressure but instead relies on carefully controlled temperature profiles. This improves material properties, such as higher density, enhanced mechanical strength, and dimensional

  What is hot pressing sintering? Hot pressing sintering is a manufacturing process that uses heat and pressure to create strong, durable parts. The process involves heating a powder material to a high temperature, typically between 1000 and 2000 degrees Celsius, and then applying pressure to the material. The heat causes the powder particles to sinter, or fuse together, and the pressure forces the particles to pack more tightly together, resulting in a denser, stronger part. Hot pressing sintering can produce various parts, including bearings, gears, seals, and other components used in various industries. The process is particularly well-suited for materials that are difficult to sinter using traditional methods, such as ceramics, metal powders, polymer powders, and composites. Compared with  pressureless sintering , hot pressing sintering can produce a higher density of composite materials or metal powders. How does it work? Hot pressing sintering is a versatile and efficient manufac
