Metal Manufacturing Services
Custom metal manufacturing from prototyping and tooling to high-volume production.
Techsun provides integrated metal manufacturing services for OEM and industrial customers, covering precision metal stamping, sheet metal fabrication, welding and assembly, and surface finishing. From prototype development to high-volume production, we manufacture custom parts and enclosures according to your drawings and specifications.
Our professional technical team designs and manufactures high-precision progressive dies and tooling, and performs DFM analysis to ensure maximum efficiency and minimal material waste.
Our stamping process provides consistent, high-precision parts for everything from small-scale prototyping to mass production of millions of units.
We offer a complete range of post-stamping services, including deburring, tapping, welding, powder coating, sandblasting, electrophoresis, painting, allodin, passivation, polishing, heat treatment, blackening, electroplating (tin, nickel, gold, zinc) and anodizing, to deliver ready-to-use parts.
