Injection molding of metal powder - choice of binder

Metal powder injection molding, as a new technology, is a kind of solid powder and organic binder homogenization, heating plasticization at a certain temperature, and then injected into the mold cavity curing molding, after removal by sintering densification. In this process, the first step is to select metal powders and binders that meet the requirements. The following small series will introduce the choice of binders for MIM technology:

1、Binder is the core of the metal powder injection molding technology, the metal powder injection molding in the binder can strengthen liquidity to suitable for injection molding and maintenance of compact type form the two basic functions, in addition the MIM experts also found on the choice of binder and it should be easy removal, no pollution, non-toxic, and reasonable cost etc.

2、The binder is usually composed of low molecular components and high molecular components plus some necessary additives. Low molecular component viscosity, good fluidity, easy to remove; High polymer component viscosity, high strength, maintain the strength of forming blank. Daihong new materials can obtain high powder loading through the appropriate proportion of the two to obtain products with high precision and high uniformity. Commonly used adhesives are: thermoplastic system (paraffin-based, oil-based and thermoplastic polymer base), gel system, thermosetting system and water-soluble system.

The above is the new material by dahong xiaobian for you to briefly introduce the metal powder injection molding binder should be how to choose the relevant knowledge, more about MIM technology and MIM material related content, welcome to consult guangdong dahong new material metal powder injection MIM technology professional team to answer for you!
