Gravity die casting, similar to gravity casting, uses molds and allows for controlled pouring by machines, making it easier to consistently reproduce quality levels. While there are shape constraints compared to gravity casting, maintaining high quality is easier once the conditions are established. 【Features】 ■ Higher dimensional accuracy and surface quality compared to sand casting ■ Integrated support from casting to machining and surface treatment *For more details, please download the PDF or feel free to contact us.

Daiwa Light Alloy Co., Ltd. conducts sand casting at its Motohama factory in Hyogo Prefecture. Sand casting is a casting method that has been used for a long time, with silica sand as the mold material. Thanks to the self-hardening properties of phenolic resin, it can accommodate both small and large castings. While it is not suitable for mass production compared to die casting, it is well-suited for creating complex shapes by combining cores and for producing large products. 【Features】 - Low initial cost, suitable for prototyping and small lot production - Comprehensive support from casting to machining and surface treatment *For more details, please download the PDF or feel free to contact us.
