Our company contributes to society through the thixotropic molding of magnesium, the precision manufacturing of magnesium and aluminum die-cast components, and the production of injection molding molds for resin and magnesium. Magnesium alloys are particularly lightweight among practical metals and are suitable materials for reducing the weight of various products (components). However, their thermal conductivity is about half that of aluminum (ADC12), which has led to the decision not to use them in heat sinks designed to dissipate heat. In response, we developed the "SHC alloy," which achieves both thermal conductivity equivalent to aluminum and lightweight characteristics. 【Characteristics】 ■ Improved thermal conductivity (AZ91D 54, SHC 99, ADC12 96) in units of W/m·k ■ Enhanced heat dissipation *For more details, please refer to the PDF document or feel free to contact us.

Our company contributes to society through the thixotropic molding of magnesium, the precision manufacturing of magnesium and aluminum die-cast parts, and the production of injection molding molds for resin and magnesium. Magnesium alloys are particularly lightweight among practical metals and are suitable as materials for reducing the weight of various products (parts). The "UH alloy" achieves high toughness and high strength by adding a small amount of carbon to conventional materials. Additionally, the addition of carbon has been confirmed to reduce internal defects (pores). 【Characteristics (compared to AZ91D)】 ■ Improved elongation (2% ⇒ 3%) ■ Increased 0.2% yield strength (160 MPa ⇒ 180 MPa) ■ Reduction of internal defects (pores) ■ Improved fluidity *For more details, please refer to the PDF materials or feel free to contact us.

Our company uses magnesium alloy chips as raw materials and employs the "thixomolding method" to mold magnesium through injection molding. Compared to die casting, this method allows for improved surface quality and precise molding of thin-walled products, enhancing dimensional accuracy and mechanical properties. Additionally, the manufacturing process is conducted without exposure to the atmosphere, making it a highly safe and clean molding method. Molding is possible in sizes ranging from palm-sized to A4 size. 【Achievements】 - Digital camera and DSLR camera parts - Mobile phone casings - Leisure goods *For more details, please feel free to contact us.

Molds are not the products that the end customer holds, but rather tools for creating those products. However, we believe that it is essential for the users of these tools, i.e., molds, to have them last long in good condition. To achieve this, we incorporate know-how and technology from the design stage, and through precise processing and assembly techniques, we strive not only for the beauty of freshly made molds but also for durability over long periods of use, maintaining the quality of the products. We continue our daily efforts toward this goal. *For more details, please refer to the related links page or feel free to contact us.

The equipment for manufacturing molds is evolving rapidly, allowing even inexperienced individuals to process them at least in form. While such technology is necessary for improving efficiency, it alone cannot produce high-quality molds. There is always a realm of craftsmanship where human intuition makes accurate judgments and creates excellent products, which cannot be replaced by machines. We will automate where possible to enhance efficiency, while in areas where human intuition is crucial, we will utilize craftsmanship, pass on skills to the new generation, and train mold craftsmen to achieve high levels of quality, cost, and delivery time, continuing to produce molds that are MADE IN JAPAN. *For more details, please refer to the related links page or feel free to contact us.*
