Powder metallurgy production process

(1) Production of powder. Sintering differs from metal melting in that at least one element remains in the solid state during sintering. During the sintering process, a series of physical and chemical processes, such as diffusion, recrystallization, fusion welding, compounding and dissolution, become metallurgical products with certain porosity.

(2) Press molding. The powder is pressed into a desired shape under a pressure of 500 to 600 MPa. [1]
(3) Sintering. In general, sintered parts can be used directly. However, for some sizes, parts requiring high precision and high hardness and wear resistance are subjected to post-sintering treatment. Post-treatment includes coining, rolling, extrusion, quenching, surface hardening, oil immersion, and infiltration. It is carried out in a high temperature furnace or a vacuum furnace which protects the atmosphere. The production process of the powder includes the steps of preparing the powder, mixing the powder, and the like.
(4) Post-processing. Plasticizers such as gasoline, rubber or paraffin are usually added to improve the moldability and plasticity of the powder.

EVA Deck Pad

EVA Deck Pad for kiteboard deck pad and SUP deck pad comes in two ways normally. One is full sheet for DIY, the other one is die cutting based on customized design.

The full sheet deck pad can be in 230cm x 90cm or 90cm x 90cm size.
