From small items to large ones! Information on sand casting, copper alloy, and aluminum casting [Video available].
Supports from 100g to a maximum of 1.5 tons! One of the few large-scale sand casting technologies in Japan!
Sand casting can accommodate everything from ultra-precision castings for small items (50g) to super-large castings (1500kg) used in machine tools and ships. Among these, we have a wealth of experience in sand casting in the 1-ton class, receiving high praise for our work. Additionally, among the many manufacturing methods available in sand casting, we employ self-hardening molds utilizing organic self-hardening sand regeneration treatment machines (alkali phenol). This method offers high self-hardening properties and excellent release, making it suitable for large sand castings. Furthermore, in addition to equipment that enables large sand casting, we have accumulated a wealth of technical know-how in casting technology through our extensive work in large sand castings. We utilize unique casting plans to deliver highly reliable products that meet demanding quality and technical requirements, including tightness and strict standards against casting defects, which are often considered challenging for large products. Notably, we have numerous achievements in high-pressure pumps and compressor components, actively tackling high-level sand castings, from complex external shapes to intricate internal shapes using multiple cores.

Company information
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)
