Mechanical Parts Coating


Powder metallurgy product parts

The advantages of powder metallurgy technology are it can process special materials, has a high utilization rate of metal materials. Therefore, the technical characteristics are particularly suitable for applications requiring extremely high dimensional accuracy and on complex shapes that are difficult to process. For example, various parts on automobiles, aerospace, and pumps (turbines, gears, pulleys, bearings, etc.).

The disadvantage of powder metallurgy products is that their strength and were resistance are not as tough as the forgings or castings. Therefore, DAHYOUNG has developed a special coating for powder metallurgy to improve the mechanical properties and optimize the hardness, heat resistance, corrosion resistance and wear resistance, without affecting the product tolerance or accuracy requirements.

Powder metallurgy mold forming

There are many types of powder metallurgy mold forming dies, including: the molding method, extrusion method, bonding method, casting method,etc. Research and statistics of powder metallurgy show that mold wear is prone to  die collapsing, die breaking, die cracking, die wear and die explosions most commonly on punch, mandrel and middle molds. In order to prolong the service life of the mold, DAHYOUNG's powder metallurgy mold coating can improve the mechanical properties of various parts and enhance the performance of hardness and wear resistance.
