Frequently Asked Questions
Deep draw metal stamping is primarily a forming process of a flat workpiece into a finished part through a series of punch and die operations calculated to reduce the diameter of the workpiece in each station. A deep draw part is any part in which the depth of the part exceeds its diameter.
Many metals can be deep drawn. In most cases they are designated by the industry standard DDQ or deep draw quality. The designation signifies the high ductility of the metal being formed through shaping and pulling through the deformation process without catastrophic failure. Grades of steel, stainless steel, aluminum and the red metals group are designated as DDQ.
A type of metal-working press known as the transfer press. The transfer press has the capability to transfer the workpiece from one punch and die operation or “station” to the next operation until the part is complete.
Yes. We have converted turned components, small castings, and tube components to deep draw. Conversions require engineering collaboration for dimensional changes to deep draw and we are successful at the process.
The advantages of deep draw conversion include: Material savings realized through a reduction in raw material scrap and w.i.p. scrap and less expense of the original raw material into strip form. Higher production rates as well as elimination of secondary processes are additional advantages.
PMP typically requires a minimum order of 10,000 pieces for any new quotation.
The Engineering and Tooling Charge on the PMP quotation encompasses the tool design for the part, the sequence of operations required, any outside costs we incur for the tooling, the toolroom time to make all the tools and set them into the press, and the development process in the press to create the part.
The Engineering and Tooling Charge is a one-time charge for the life of the part. A second Engineering and Tooling Charge would only occur if a print revision requires tooling modifications.
The customer has ownership of the tools while PMP retains all the intellectual property required to create the tools.
From time to time PMP performs 5S on the tool crib and identifies tooling we deem obsolete based on production records. We then work closely with those customers to arrive at a final disposition for them.
Yes, all the time, through chat room help, video conferences, and teleconferences. Our goal is to help our customers in defining their critical features, dimensions, and tolerances and then aligning these criteria to our deep draw forming process and capabilities.
No, we have nothing “off the shelf.” All components are proprietary to our customers.
Factors that determine the price of a component include the cost of the raw material, volume, and the rate of production. Generally, we are a business of pennies, nickels, and dimes per part.
We do not build prototypes through the use of “soft” or perishable tooling. Once the tooling is complete we engage in prototype runs, engineering trials, and full-scale production.
Yes. We have a supply chain that specializes in plating, heat treatment, mechanical secondaries, and specialty cleaning to the micron level.
