I will provide a detailed explanation of the overview of molds, molding, and sintering!
The molds are made of hard metals (such as carbide, SKD, etc.). They are primarily composed of a die, upper and lower punches, and a core. For multi-stage or complex shapes, additional molds may be required, and devices that perform auxiliary operations connected to the molding press will be necessary. The raw powder is filled into the mold set in the molding press, and pressure is applied from above and below to compact it, after which it is removed from the mold. The sintering time is generally around 7 hours. *For more details, please refer to the PDF document or feel free to contact us.*

basic information
**Features (Excerpt)** <Shaping> ■ When pressure is applied, elastic and plastic deformation of powder particles occurs within the mold. ■ Some particles deform and break into smaller particles, which fill the gaps between particles, increasing contact between them, resulting in high density and forming a compacted powder. ■ The strength is still low at this stage. <Sintering> ■ By heating at a temperature lower than the melting point of the main component, the bonded areas of the compacted powder are diffused, providing strength to the sintered parts. ■ The sintering phenomenon occurs due to viscous flow, surface diffusion, internal diffusion, and evaporative diffusion. ■ As a characteristic, countless voids (porosity) are present. *For more details, please refer to the PDF document or feel free to contact us.* *For those who want to know more about iron powder, please contact our supplier, Heganes Japan Co., Ltd.*
