Materials and Process Engineering

Turning customer-specified material, surface, and thermal requirements into practical manufacturing control.

Translation

A drawing sets the target. Sanjin turns material, surface, and thermal requirements into the process choices that shape the finished part.

Customer requirement

  • Geometry and tolerance
  • Material and surface condition
  • Thermal or assembly requirement

Tooling edge and forming direction

How the part is cut, formed, and supported during stamping.

Burr and edge control

Where burr risk appears, and how finishing or inspection should focus.

Heat-treatment window

Temperature, hold time, and cooling conditions that affect shape stability.

Plating thickness uniformity

Surface preparation, plating control, and checks for functional areas.

Cleaning and protected surfaces

Handling steps that keep sealing, bonding, or contact areas ready for use.
