Frequently Asked Questions
JMS is your reliable source for deep-drawn stampings. We focus on process conversions, design for manufacturability, VAVE, and cost-out. We’ve converted machined parts, cast parts, and cold-headed parts to low-cost, feature-rich stampings. Our product engineers, toolmakers, and sales support team are ready for your next project.
What is deep-draw stamping?
Deep-draw stamping is a high-speed, high-value shape transformation process in which sheet metal is drawn into a forming die to produce round, square or irregularly shaped parts.
What features can I get “for free” when they are included in the stamping die?
Side-holes, beads, splines, serrations, lances, tabs, tapped or rolled threads and flanges to name a few.
What are commonly used secondary services for our stampings?
Heat treatment, specialty cleaning, surface treatments, polishing and deburring among others.
What other value-add processes can JMS provide?
We are experienced with multi-piece assemblies and routinely perform welding and other joining processes to our stampings. We’re prepared to consider any value-add process you may require.
What raw material thicknesses can be used in the stamping process?
We have worked on projects with material as thin as 0.25mm and as thick as 7.0mm. Most of our parts are made from material in the 0.5mm to 2.5mm thick range.
What materials can be stamped?
Cold rolled steel in multiple grades, pre-plated and coated steels, stainless steel, aluminum, copper and brass. Ask us if you have an exotic material you would like us to consider.
How long does it take to tool-up a new stamping?
Off-tool samples will be ready in about 14 to 16 weeks. Full production supply can be ready within weeks of your final approval.
Does JMS have experience with take-over (re-source) work?
Yes! JMS has years of experience supporting customers re-source projects. If you find yourself in a jam with an existing supplier, we can help. We can typically run progressive die tools as-is and transfer press jobs with some rework to the tooling.
Our in-house tool department and experienced toolmakers put us in a unique position to quickly assist with any tool modifications that may be required to deliver the same part (or better!) than you were purchasing from the other supplier.
For any other questions, don’t hesitate to contact us.
