Progressive Die Stamping of a Steel Bracket Assembly for the Automotive Industry
Perfection Spring & Stamping Corp. was contracted to manufacture a large series of steel bracket assemblies for the automotive industry. This bracket assembly consisted of three mounting legs per component and a cover bracket that was originally die casted. Through prototyping and development testing, our team of engineers established that this expensive die casting process could be replaced with drawn metal stamping operations. This solution provided better product at considerable cost savings!
Offering a more stable metal forming procedure, drawn metal stamping eliminated the need for other secondary operations and fasteners. Moreover, with the ability to maintain tighter tolerances - as well as provide better transfer of heat in extreme temperatures to meet the customer's RFI/EMI requirements - this process yielded a higher quality product. Additionally, the progressive die replaced the need for expensive maintenance costs associated with die cast tooling. When the results were tabulated, this solution generated an annual cost savings equal to $200,000 per year over the five-year program, providing our customer with a total savings of $1,000,000.
