Metal Stamping Services

JNS Industries offers precision metal stamping services for light and medium duty materials that include steel, stainless steel, and brass. Our 2 to 25 ton punch presses use single hit and progressive dies for stampings used in the medical, dental and surgical industries. Our flexible stamping process accommodates low to high volume production, with the capability of rapid prototyping.

The Ontario, CA facility uses a fully equipped in-house tool room to custom fabricate each metal stamping die set. Based on the customer design constraints, JNS Industries provides design analysis and die modifications to improve the functionality of the stampings' end use. We offer a variety of finishing options that include bead blasting, de-burring, plating, heat treating and powder coating.
