About Can manufacturing
We have experience in manufacturing various steel materials such as SUS304, 316, 321, Hastelloy, Inconel, titanium, and aluminum, as well as double-wall pipes for hydrogen and other industrial equipment.
We specialize in high-precision can manufacturing of thin products from 0.5 mm to 3 mm thick, and we can also handle machining after welding. (For details on dimensions, etc., please refer to the Equipment List.)
In addition, when welding special materials, we request a specialized institution to conduct cross-sectional observation tests to confirm the amount of welding, cracking of the base material, and metallurgical conditions before welding.
Based on the results, we have established welding methods and technical skill certification system to guarantee reliable quality to our customers.
Precision Welding
We are capable of meeting geometric tolerances with high required accuracy. We have established a stable supply system by establishing working conditions, complying with work procedures, and thoroughly implementing technical skill certification system in order to fabricate products that meet the requirements.
Precision Canning
Precision can manufacturing area divided into booths to prevent contamination with foreign materials
Highly accurate work management system
Canning Process
Heat-resistant alloy cans
Stainless steel canned products
Elaborate care work after welding
Maintenance work
For maintenance work such as periodic inspections, we disassemble the assembly, conduct various inspections (PT, RT, pressure resistance tests), replace parts, weld repair, clean parts, and reassembly.
We also specialize in checking and removing foreign objects inside products using the latest video scopes.
Improved work efficiency
We have introduced industrial robots to improve work efficiency.
We use robots for welding (semi-automatic welding) and plasma cutting separately to improve work efficiency and stabilize quality through automation.
