TMS has nearly a century of producing preformed blanks with our deep drawing, rolling, stamping & welding capabilities.  Since metals can only be worked so much before requiring a thermal treating of some kind or failing, metal spinning alone is sometimes not the optimal processing method.  Utilizing a combination of welded blanks with aerospace quality welds or seamlessly deep drawn preforms can reduce processing costs of spun only parts and dramatically improve the level of quality by minimizing the straining or thinning of the material.  Minimizing straining of material is especially important in materials that strain harden like stainless steel, nickel, and titanium alloys or materials in general that have low elongation.  Applications requiring good fatigue life or need to minimize risk from cracking normally benefit using a gently produced preform then spinning it to the final shape.  This two step process can avoid issues common with metals that are well worked or highly strained.

Another added benefit using preforms can be the elimination of weld joints and the need to manufacture multiple parts.  Round parts made in two pieces and welded together can sometimes be manufactured in one piece.  Using a deep draw preform and spinning a final shape, the once two piece weldment now is a seamless part.  This typically improves quality and the ability of the part to perform while normally reducing lead time, supply chain complexity, and or cost.  Call us today and we would be happy to see what options you have to do more.
