SPM-PROCEDURES

SELECTING

Select a type among Steel, Stainless steel, Copper powders according to mechanical properties of the final product.

MIXING

Mix sub-materials with a suggested range of ratios in order to obtain the certain mechanical properties.

COMPACTING

Compact the mixed metal powders with a certain pressure into the mold.

SINTERING

Sinter the compressed/compacted products at lower temperature than melting points so as to produce a product with the mechanical properties by diffusion and combination of metal powder particles.

SIZING

Compact again the output from the SINTERING step so as to increase the dimensional accuracy.

POST PROCESSING

  1. Process
  2. Heat Treatment (Carburizing / Induction hardening / Steam)
  3. Barreling
  4. Sanding
  5. Surface Finish (Black Oxide, Chrome/nickel plating)
  6. Other misc.

INSPECTION

Implement an inspection to confirm whether the final output complies with customer’s requirements. (material, shape, dimension, etc.)
