#1 What is powder metallurgy?
01
It is used for home appliances, car parts, industrial robots,
and parts of wearable
devices.
"Powder metallurgy" is one of the engineering methods used to manufacture products with a complex shape at high precision. Methods, such as casting, forging, cutting, and pressing are well-known, but powder metallurgy is known only by a limited number of professionals. The method is widely used for familiar home appliances, such as air conditioners and refrigerators, car parts, industrial robots, and the manufacture of parts of cutting-edge products, such as wearable devices including smartwatches.
02
Mixing a variety of metals and ceramics,
this method can mass-produce materials
with unique features.
"Powder metallurgy" is a process where raw material powders, such as metal powder and ceramic powder, are mixed and placed into a mold where they are subjected to high pressure to form a shape and high temperature to increase its strength. What's special about this method is that it can reduce the loss of materials and mass-produce complex products with high precision. It can create materials with unique characteristics by mixing powders of different substances to produce special features, such as wear and heat resistance, increased or decreased weight, and magnetism. If we were to say casting is "chocolate production (melting, cooling, and solidifying)," powder metallurgy would be seen as similar to "cookie production (mixing powder, forming it into a desirable shape, and baking it at an appropriate temperature)."
