Requirements for Organic Adhesives in Metal Powder Injection Moulding Technology

Metal powder injection moulding technology (MIM) is a new powder metallurgy forming technology formed by introducing modern plastic injection moulding technology into the field of powder metallurgy. Below I give you an introduction to the metal powder injection moulding technology on the specific requirements of organic adhesive.

Metal powder injection moulding (MIM) technology not only has the advantages of conventional powder metallurgy process less process, no cutting or less cutting, high economic efficiency, and overcome the traditional powder metallurgy process products, material is not uniform, low mechanical properties, not easy to form thin-walled, complex structure of the shortcomings of the MIM technology is particularly suitable for the mass production of small, precise and complex parts as well as metal parts with special requirements. The size of the metal powder particles used is generally 0.5-20μm.

Theoretically, the finer the particles, the greater the specific surface area, easy to form and sinter, while the traditional powder metallurgy process uses coarser powder. The role of the organic bonding agent is to bond the metal powder particles, so that the mixture is heated in the barrel of the jet machine with rheological and lubricating properties, that is to say, the carrier that drives the powder flow. Therefore, the choice of adhesive is the carrier of the whole powder, but also the key to the whole powder injection moulding.

Therefore, the requirements of MIM technology for organic bonding agent are as follows:

1. Using less bonding agent can make the mixture produce better rheology.

2. No chemical reaction with the metal powder in the process of removing the bonding agent.

3. The bonding agent should be easy to remove, there should be no carbon residue in the product.

These are the specific requirements of metal powder injection moulding technology for organic bonding agent, we hope this information can help you understand the key points of MIM technology. If there are other questions, please consult our engineers: edith@xy-global.com
