サトキン Company Profile

Robot parts can be made through casting! The beautiful cast surface is a must-see! We boldly take a step into the unknown to create products that benefit society.

At Satokin, we are building a unique casting plan to achieve high-precision and high-quality sand casting for both small and large items. We specialize in aluminum and copper alloys, developing our original know-how in sand casting technology, including mold design and sand core design tailored to shapes and specifications, while also working daily on the development of new methods to further improve quality. We have a strong reputation for reliable quality, even for products that require high confidentiality and strict standards against casting defects. By using fine-grained sand molds, we achieve surface roughness comparable to that of metal molds and realize a wall thickness of 1.25 mm through our unique casting methods. 【Main Equipment】 Organic self-hardening sand regeneration treatment machine (alkali phenol) Continuous mixers: 3 units Molding lines: 2 lines (for large items, for small items) Melting furnaces: 5 units (copper alloy: 300kg, 680kg x 2; aluminum alloy: 200kg, 650kg x 2) Luminescent analysis device: 1 unit Three-dimensional measuring machine: 1 unit Fine cutter: 1 unit Vacuum pump: 1 unit Shot blast machines: 2 units (drum type, table type) Cranes: 4 units of 2.8t, 2 units of 1t (jib type)
