Technology

FSW imag

Friction Stirring Welding

It is a solid-phase bonding method that utilizes frictional heat with the material while rotating the tool at high speed.

It is a method of bonding without melting the mother body, heating and softening as an individual, and further giving plastic deformation

Welding image

Airtight Welding

We perform high-precision airtight welding for skilled engineers and correction of flatness using our own press machine.

Stainless steel water-cooled jackets and chambers are used in high vacuum levels, requiring high-precision airtight welding with Tig welding

Machining image

Machinery Processing

We can manufacture a wide range of products from plates to box chambers

By linking our own machining center with Horizontal boring machine, we can handle a wide range of products.
The main work materials are austenitic stainless steel and copper.
Other materials to be discussed ,if required

Example

case_01

Backing Plate

It is the core component of sputtering equipment, which is one of the semiconductor and FPD (flat panel display) manufacturing equipment.

case_02

Round Stainless Cold Plate

It is one of the important components of cooling systems used in high temperature environments, such as electronic components and medical devices.

case_03

Vacuum Chamber

It is a sealed reaction vessel to cause scientific and physical reactions internally.
