When your product design calls for seamless cylindrical or box-shaped components, deep draw metal pressing offers an efficient, cost-effective solution that’s difficult to match with other manufacturing methods. At Cotmor Tool and Presswork, we’ve spent over 70 years perfecting this specialised technique for clients across the West Midlands and beyond.
Deep draw pressing is a metal forming process that transforms flat sheet metal into hollow, three-dimensional shapes without seams or joints. Unlike shallow forming, deep drawing involves pulling metal significantly deeper than its original diameter, creating components where the depth exceeds the diameter of the part.
The process uses a punch and die set within a hydraulic or mechanical press. As the punch descends, it forces the metal blank into the die cavity, gradually forming the desired shape. Multiple drawing stages may be required for particularly deep or complex components, with each stage progressively increasing the depth whilst maintaining material integrity.
Strength and Durability
Because deep drawn components are formed from a single piece of metal, they eliminate weak points associated with welded or multi-piece assemblies. The cold-working process actually work-hardens the material, enhancing its strength characteristics. This makes deep draw pressing ideal for components that must withstand pressure, impact, or demanding operational environments.
Superior Surface Finish
The controlled nature of the deep draw process produces consistently smooth surfaces, both inside and out. This reduces or eliminates the need for secondary finishing operations, saving time and costs whilst delivering aesthetically pleasing results straight from the press.
Cost-Effective Production
Whilst tooling development requires upfront investment, deep draw pressing becomes increasingly economical as production volumes rise. The process is remarkably fast once tooling is finalised, making it perfect for medium to high-volume manufacturing runs. Material waste is minimal compared to machining processes, further improving cost efficiency.
Design Flexibility
Modern deep draw techniques can accommodate various materials including stainless steel, aluminium, brass, copper, and mild steel. Complex shapes with varying wall thicknesses, flanges, and intricate details are all achievable, giving designers considerable freedom whilst maintaining structural integrity.
