What are the strict requirements for organic adhesives for metal powder injection molding

By analyzing the rheological behavior and apparent activation energy of viscous flow, the formability of various formulations was effectively evaluated. The technological parameters of temperature have a significant effect on formability. The key in the operation process is the selection of the patch. The requirements are relatively strict.

The function of the organic adhesive is to bond the metal powder particles, so that the mixture is heated in the barrel of the injection machine with rheological and lubricating properties, which is the carrier that drives the powder flow. Therefore, the choice of adhesive is the carrier of the whole powder. Therefore, the selection of adhesion is the key to the whole powder injection molding. Requirements of metal powder injection molding for organic adhesives:

The adhesive can make the mixture have good rheological properties when the dosage is small; No reaction, no chemical reaction with metal powder in the process of removing adhesive; It is easy to remove, and there is no carbon residue in the product.

The metal powder and organic adhesive are uniformly mixed together to make various raw materials become the mixture of injection molding. The uniformity of the mixture directly affects its fluidity, thus affecting the injection molding process parameters, as well as the density and other properties of the final material. The injection molding process principle is the same as the plastic injection molding process, and the equipment conditions are basically the same.

because

The products of metal powder injection molding process can be used to manufacture metal parts with complex economic structure, so it can provide significant cost savings for smart manufacturers, which can reduce part of the cost in many cases. Later, two or more parts can be replaced with a single powder injection molding part assembly, thus eliminating the cost of these assembled parts. powder metallurgy https://www.zw-metalware.com/
