PR message
We have grown by building our expertise in pipe bending processing. Our main product, automotive heat exchanger pipes, boasts a monthly production of 900 varieties and 900,000 units. Since heat exchangers are essential components even for electric vehicles, our business operations will remain unaffected even if the era of engine-powered cars comes to an end.
Additionally, medical pipes used in surgical instruments account for 40% of our sales. By not relying on a single industry, we maintain stable and profitable operations.
Business Activities:
Pipe bending & sheet metal processing
Manufacturing of automotive parts (radiator components, air conditioning components)
Manufacturing of medical equipment parts (endoscopic surgical instrument components)
Manufacturing and sales of educational toys [Pipegram]
Development, manufacturing, and sales of pedal-operated bottle stands
Workable Sizes & Materials:
Work Sizes:
Diameter: Min. φ4 – Max. φ65
Thickness: t = 0.2 – 3.0 mm
Materials:
Aluminum, Stainless Steel (SUS), Iron, Copper, Brass, Titanium
Pipe Bending Processed Products
We have a well-equipped laser processing facility, including:
4-axis precision cutting laser machine
3D (2KW) laser cutter
2D (4KW) laser cutter
Since 2008, we have introduced 4-axis precision cutting technology (cutting accuracy of 4/1000mm) for precision processing. If the material thickness is between 0.1mm and 1.0mm, we can ensure this level of cutting accuracy. This allows for the precise and complex cutting of sheets, pipes, and other materials.
Pipe Bending Products
Features of Spiral-Shaped Pipes for Heat Exchangers Like Heat Pipes:
The functional part of the heat exchanger can be reduced to 1/2 to 1/3 the size of conventional serpentine-shaped pipes.
Heat exchange efficiency improves by approximately 30–50% compared to traditional designs.
A multi-layered structure for the heat exchanger's functional parts is possible.
→ With this technology, the pipe does not take on a helical shape. Instead, the height (Z-direction) of the spiral-shaped product matches the pipe's diameter.
→ As a result, spiral-shaped pipes can be easily stacked in layers, allowing for space-saving designs and leading to overall product miniaturization.
This breakthrough technology enables freeform bending of pipes with the required minimum bending radius (R) by continuously moving an eccentrically positioned bending die (mold).
Pipe Bending Processed Products
Equipment Used: 10-ton press machine
By applying our pipe bending expertise, we also perform flaring and deep drawing processes using press techniques.
This product was proposed to our customers as a VA (Value Analysis) solution, transitioning the manufacturing process from cutting to pressing. This advancement is a testament to the dedication of our in-house engineers.
Pipe diameter range: φ8 to φ35
Materials: Aluminum, Stainless Steel (SUS), Iron, Copper, Brass, Titanium
We specialize in manufacturing aluminum pipes for air intake systems and heaters used in trucks, special vehicles, construction machinery, and automobiles.
Our pipe bending process is carefully classified based on equipment, jigs, and processing methods. We provide optimal processing solutions tailored to the customer’s design, shape, and intended application.
Our expertise in thin-walled brass pipe brazing is a skill traditionally associated with experienced craftsmen, but as aging progresses in the industry, we are actively training young talent to ensure sustainable production.
We also provide essential training in aluminum brazing, electric welding, and gas welding as mandatory skills for new employees upon joining the company.
