Induction Hardening
Induction hardening uses electromagnetic induction to heat specific surface areas of a part — with heating times measured in seconds — followed by immediate water or polymer quenching. The rapid...

Isothermal Forging
Isothermal forging keeps both die and workpiece at the same temperature throughout the forming cycle — eliminating die chilling and enabling complex, near-net shape components in aluminum alloys...

Hot Forging
Hot forging is a metal shaping process that uses heat — typically 1,000°C to 1,200°C for steel — to reduce flow stress and enable complex deformation in a single press stroke. At these...

Deep Drawing
Deep draw stamping is a metal forming process that transforms flat sheet metal or tubular blanks into seamless, hollow components where the depth typically exceeds the diameter. The process uses a...

CNC Turning
CNC turning produces cylindrical components with ±0.02mm accuracy — from Φ2mm pins to Φ500mm shafts, up to 1000mm in length. We machine stainless steel, carbon steel, alloy steel, aluminum, and...

Spheroidizing Annealing
Spheroidizing annealing transforms the lamellar carbide structure in steel into a spheroidal (globular) form through controlled heating and slow cooling. This reduces hardness, improves...

Carburizing
Carburizing is a thermochemical process that diffuses carbon atoms into the surface layer of low-carbon steels, increasing surface carbon content to approximately 0.8%. After quenching, this...

Tempering
Tempering is a mandatory post-quenching heat treatment. Fresh martensite is hard but brittle, with high residual stress. Without tempering, a quenched part is prone to cracking or fracture in...

Surface Lubrication
Surface lubrication applies solid or dry-film lubricant coatings to metal surfaces to reduce friction, prevent galling, and extend die life in cold forming operations . The lubricant layer is...

Shot Blasting
Shot blasting is a mechanical surface preparation process that propels spherical metal shot at high velocity (65–110 m/s) using a centrifugal wheel . The impact of the shot removes mill scale,...
