Deep draw is a metalforming technique that is used to make seamless, one piece enclosures from metal with a closed end or bottom. Other descriptions for what we make are cans, cases, housings, headers, shells and covers.
What differentiates our enclosures from fabricated enclosures is that ours are one piece – no welded corners or bottoms, no leak issues, and very stable dimensional repeatability.
In many cases, deep drawn enclosures are a lower cost solution to fabricated enclosures when welding costs and leak testing are considered. Additionally, deep drawn round enclosures are an excellent alternative to welded tubing, particularly where roundness and seamless construction are required.
The deep drawn solution eliminates issues associated with another method of enclosure manufacturing known as impact extrusion. The shortfall with impact extruded enclosures is that there is no draft angle along the sidewalls. This creates a challenge when assembling internal components or when using the enclosure as a mold.
