We would like to introduce the "aluminum castings" that we handle. By replacing the gas in the cavity with oxygen and reacting it with aluminum, it is possible to produce raw materials with fewer blowholes. Additionally, by collapsing and removing the core after the aluminum has solidified, it is possible to manufacture hollow-shaped aluminum castings. 【Features】 ■ By replacing the gas in the cavity with oxygen and reacting it with aluminum, it is possible to create raw materials with fewer blowholes. ■ By collapsing and removing the core after the aluminum has solidified, it is possible to manufacture hollow-shaped aluminum castings. ■ During product design and mold design, flow and solidification simulations, known as casting CAE, are conducted. *For more details, please refer to the related links or feel free to contact us.

Die-cast products are manufactured using a casting method that fills molten aluminum into a mold at high speed, high pressure, and in a short time. This pressurized molding method allows for the efficient production of complex shapes and high-strength products. At Toyo Densan Co., Ltd., we produce automotive industry parts, primarily engine and transmission components, as well as parts for other industries using this casting method. In recent years, we have been utilizing die-casting machines equipped with multi-stage injection mechanisms and mold temperature control devices. 【Features】 ○ Stable internal quality ○ PF method allows for heat treatment ○ Efficient production of complex shapes and high-strength products ○ Capable of producing complex gear shapes, thin-walled inclined wing shapes, and thin-walled hollow shapes For more details, please contact us or download the catalog.

Gravity cast products are manufactured using a casting method that involves injecting molten aluminum into a mold and filling it by gravity. By using a collapsible core known as a shell core, it is possible to efficiently produce various complex-shaped products. At Toyo Densan Co., Ltd., we produce automotive industry parts primarily for engine and transmission components, as well as parts for the leisure industry such as motorcycles, buggies, and boats using this casting method. 【Features】 ○ Efficient production of complex-shaped products ○ Balancing lightweight and strength ○ Integrated production from casting to machining to pressing [Main Products] ○ Complex hollow structure hydraulic circuit integrated oil pump cover For more details, please contact us or download the catalog.

We manufacture and prototype products using the optimal methods based on product shape, manufacturing conditions, and other factors.

We would like to introduce our "High-Quality Die Casting." We possess horizontal opening vertical shot layer flow filling die casting equipment and are engaged in mass production of high-quality die castings that can undergo heat treatment (T6). Additionally, with PF (Pore Free) die casting, we can replace the gas in the cavity with oxygen and react it with aluminum to create materials without blow holes. 【Features】 ■ Thick-walled products utilize horizontal opening vertical shot SDC machines (Toshiba DX) ■ Thin-walled products utilize PF die casting method ■ Both can undergo heat treatment (T6 treatment) *For more details, please download the PDF or feel free to contact us.
