We would like to introduce a case where our aluminum technology has been adopted for "high roundness extruded materials." Aluminum extruded materials are used in various components within the electrical, mechanical, and automotive industries due to their advantages such as lightweight, recyclability, and good formability. High roundness extruded materials have made it possible to achieve dimensional tolerances (roundness) within the hollow sections, which were considered difficult for extruded materials, by controlling our long-accumulated mold technology and extrusion conditions, allowing for roundness of 50 to 100 micrometers or less (about 1/6 of JIS special grade). [Case Overview] ■ Challenges - Enhance competitiveness in terms of cost and quality for mechanical components. ■ Effects - Manufacturing with roundness of 50 to 100 micrometers or less (about 1/6 of JIS special grade) is possible. *For more details, please refer to the related links or feel free to contact us.

We would like to introduce our various shapes of "general-purpose materials" that we handle. These general-purpose materials can be used for a variety of applications, including angles, flat bars, square pipes, and round pipes. Since we own the molds for these general-purpose materials, there are no costs for mold production. The colors available are silver (sealed, glossy, matte), stainless steel, dark stainless steel, bronze, black, and white. 【Notes】 ■ The alloy type is only 6063 alloy. ■ All of these shapes are made to order. → While we do own and manage the molds, we do not have stock of the products. ■ There are restrictions on the order quantities. ■ The standard dimensions are L = 3000 to 6000. *For more details, please download the PDF or feel free to contact us.

The "Offset SS Type" is a heat sink that improves heat dissipation by approximately 30%. By offsetting the fin pitch every other row, it significantly enhances performance compared to conventional extruded materials (comb-shaped) heat sinks. With a fin height of (maximum) 1/2, it can achieve performance equivalent to our conventional extruded material heat sinks, allowing for miniaturization and weight reduction of the equipment. The surface treatment can accommodate anodized specifications (colored), and it is capable of precision cutting, precision machining, and drilling processes. 【Features】 ■ Dividing and offsetting the fins disrupts the temperature boundary layer ■ Increases opportunities for air to collide with the fins, improving heat dissipation performance ■ Suitable for equipment that requires forced air cooling and space-saving designs ■ Surface treatment can accommodate anodized specifications (colored) ■ Capable of precision cutting, precision machining, and drilling processes *For more details, please refer to the related links or feel free to contact us.
