Craftsmanship
Heat Treatment
Either carburizing or nitriding heat treatment is carried out over a long period of time to a sufficient depth, and the surface hardness is checked batch by batch.
Coating
After the original titanium-plated series was well received by customers, it cooperated with MIRDC Taiwan to develop DLC-diamond-like carbon coating series plungers. Recently, a double-coated series with both core and shell coatings has been launched.
Clearance
The production line extensively uses CNC machining equipment and experienced personnel with skilled techniques. The assembly clearance between components can reach 2µm.
Straightness / Roundness
The plunger couplings on the production line are measured one by one by means of an automatic multi-point laser outer diameter and roundness tester, enabling us to produce plungers with straightness and roundness of an extremely high standard.
