Specific requirements for organic adhesives for metal powder injection molding technology

Metal powder injection molding (MIM) is a new type of powder metallurgy forming technology, which introduces modern plastic injection molding technology into the field of powder metallurgy. The following big new material small make up to introduce the specific requirements of metal powder injection molding technology for organic adhesives.

Metal powder injection molding MIM technology has not only the conventional powder metallurgy process, no or less cutting, high economic benefit, but also overcomes the traditional technology of powder metallurgy products, material uneven, low mechanical performance, not easy forming thin-walled, the shortcomings of complex structure, metal powder injection molding manufacturers found metal powder injection molding MIM technology is particularly suitable for mass production of small complex, precision parts and metal parts with special requirements. The size of metal powder particles used is generally 0.5 to 20 microns.

Theoretically, the finer the particle, the larger the specific surface area and the easier it is to shape and sintering, whereas conventional powder metallurgy USES coarser powders. The function of organic adhesive is to bond metal powder particles, making the mixture heated in the jet cylinder rheological and lubricity, that is to say, the carrier that drives the powder flow. Therefore, the choice of adhesive is the carrier of the whole powder and the key of the whole powder injection molding.

Therefore, the requirements of MIM technology for metal powder injection molding on organic adhesives are summarized in the paper.

1. Less adhesive can make the mixture produce better rheological property;

2. No chemical reaction with metal powder during the removal of adhesive;

3. Easy to remove, no carbon residue in the product.

Above is the specific requirements of metal powder injection molding technology for organic adhesives, I hope the introduction of small series of big new materials can help you. If you have other questions, please consult daehom new material technical team!
