Achieving mold-level surface precision and a thickness of 1.25mm! A case study of Satokin's aluminum alloy casting.
We would like to introduce a case study of aluminum alloy casting by Satokin, an expert in sand casting of aluminum and copper alloys. The "HEAT SINK" achieves mold-like surface precision by using fine-grained sand. Additionally, it has realized a thickness of 1.25mm, which is said to be impossible with the sand mold process. 【Features】 ■ Uses fine-grained sand ■ Industries served: Electrical component manufacturers ■ Lot sizes: 1 to 100 units/month ■ Product size: 250mm × 100mm × 30mm *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Specifications】 ■Product Name: HEAT SINK ■Material: AC4C-F ■Product Weight: 800g *For more details, please refer to the PDF document or feel free to contact us. Casting is explained in "Basic Knowledge You Can Understand Just by Reading" available here: https://note.com/satokin5522/ Here is an excerpt introducing "What is Sand Casting." 【What is Sand Casting】 Suitable for product dimensions ranging from 50mm to about 3000mm, with quantities from one to several hundred pieces per lot. A sand mold is created by mixing sand grains with a binder or additive such as bentonite (a clay mineral), water glass, or resin. It can accommodate complex shapes and allows for quicker and more cost-effective production of castings compared to die casting for small production runs. Thank you for reading. Please feel free to contact us for any minor inquiries. We would appreciate it if you could mention that you saw us on Ipros!

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)
