- Deep drawing is a metal forming process in which a flat sheet metal blank is transformed into cylindrical, square, or other complex hollow shapes through multiple forming stages.
Compared with other forming methods, deep drawing tends to cause die galling and material adhesion more easily. Therefore, successful mass production depends on the careful selection of tool materials, finishing methods, surface treatments, and forming lubricants.
Kyoshin has extensive experience in deep drawing processes for a variety of materials, including:
・Brass
・Aluminum
・Stainless Steel
- (Product Overview)
This product was previously manufactured by separately forming a pipe component and an outer-profile component, then welding them together into a single assembly.
By redesigning the process and manufacturing the component entirely through press forming, Kyoshin achieved a 30% cost reduction compared to the conventional method. This is a successful example of converting from a multi-process manufacturing approach to an integrated press-forming process.
・Material: Brass (C2680-O)
・Thickness: t = 0.80 mm
- (Product Overview)
This component can be manufactured with both inner and outer diameter tolerances of ±0.01 mm.
Because a mating component slides inside the cylindrical section, maintaining precise inner diameter accuracy is critical to product performance.
・Material: Brass (C2680-O)
・Thickness: t = 0.50 mm
