Production

  1. Stage 1 : DESIGN

    > receive customer demands,
    assess development feasibility,
    and plan for efficient production processes

    · 2D,3D design / CAE simulation / Manufacturing process design

  2. Stage 2 : DIE SINKKING

    > process materials swiftly and accurately according to the designed blueprints




  3. Stage 3 : MATERIAL

    > prepare the customer-specified steel grade (alloy steel, carbon steel, stainless steel, etc.).

    · Chemical composition analyzing, Dimension check

  4. Stage 4 : CUTTING

    > cut the material into specifications suitable for forging operations

    · Band Saw / Billet Shear
    · Dimension check

  5. Stage 5 : HEATING

    > To facilitate efficient forging operations, the cut material is placed in a heating furnace and heated for a specific duration.

    · Induction heating / Batch furnace

  6. Stage 6 : FORGING

    > shape the material according to the created mold

    · Rolling / Free forging
    · Hammer / Press forging

  7. Stage 7 : HEAT TREATMENT

    > heat the product to a specific temperature and cool it at a rate that enhances the desired properties or metal structure according to the customer's requirements

    · Quenching & Tempering
    · Heat time, Temperature,
      Cooling procedure check
    · Hardness inspection

  8. Stage 8 : FINISHING TREATMENT

    > correct any deformations occurring during the forging process and ensure the cleanliness of the surface

    · Shot blast / Straightening
    · Dimension check
    · Surface defect check



  9. Stage 9 : INSPECTION

    > inspect using various methods to ensure compliance with customer requirements.


    · Surface Defect
    · Dimension
    · Mechanical test
    · Microstructure Test
    · Magnetic test
    · Ultrasonic Test

  10. Stage 10 : MACHINING

    > If the customer desires, we provide a one-stop service that includes processing.

    · Centering / Drilling / Facing / Antirust / Painting / Assembly

  11. Stage 11 : PACKING & DELIVERY

    > prepare to ensure the safe arrival of the product to the customer
