Entire process of our product manufacturing.
-
powder metal
We can use any metal than can be transformed into power.
Our main materials are iron and copper. -
Mixing
Mix iron and powder metal with different composition at designated ratio.
-
Molding
- Molding
- Mixed powder metal is formed in precision mold and being pressed by automatic molding machine.
- Warm pressing
- Powder metal is formed while being kept under a certain level of temperature. Molded parts have higher density and better durability by this molding method.
-
Sintering
- Sintering
- Molded parts are sintered in the fume gas under the temperature below the melting point.
- High temperature sintering
- To densification and improve durability, sinter parts under the temperature of above 1200℃.
-
Post treatment and finishing
- Sizing coining
- After pressing and sintering the parts, place in the mold again and apply pressure to improve the accuracy of dimension and density.
- Machining
- Machinery process incudes drilling and grinding.
- Oil impregnation
- For longer lasting effect of lubricity without exhaustion of lubricant, impregnate lubricant into pores of sintered parts.
- Heat treatment
- Apply heat then cool down to change hardness of the part to designated level.
- Surface treatment
- To improve corrosion and abrasion resistance. We do steam and plating treatment.
