Precision Stamping

Interplex’s heritage in precision metal stamping dates back to the company’s origins in 1958. A premier precision metal stamping professional in the industry, we specialize in the stamping of tight-tolerance, close-pitch, high-precision and light-gauge metal components as well as thicker gauge, larger metal components and assemblies.

In order to consistently provide excellent quality precision stampings, our robust internal tooling capabilities ensure all of our progressive stamping tools exceed customer requirements. For progressive tooling design, we employ top-of-the-line CAD packages such as AutoCAD and CADKEY, as well as 3D packages such as Pro E and SolidWorks. Each facility has in-house surface grinding, programmable CNC centers, sinker EDM and wire-cut EDM technologies to support precision metal stamping operations.

Precision Metal Stamping

Interplex’s global facilities are equipped with over 600 metal stamping presses with tonnage ratings ranging from 5 – 800 tons and speeds of up to 1,500 strokes per minute. We utilize leading precision metal stamping equipment (manual, progressive or robotic lines) from brands shown below.

Our comprehensive range of equipment ranges from precision high-speed equipment to normal and long stroke presses. This enables us to produce a variety of miniature parts, heavy-duty metal components, and anything in between, with products’ thickness ranging from 0.002″ – 0.180″.

We also leverage on state-of-the-art precision metal stamping technology including precision cold forged progressive stamping and multi-slide stamping, to continually exceed the limits of conventional metal stamping processes. We also have skiving equipment to contour metal thickness and configuration as required.

Our full suite of metal stamping capabilities is complemented by value-added processes such as in-process inspection with CPK analysis, press-mounted vision systems, aqueous cleaning systems, atmosphere-controlled ovens for heat treatment of Beryllium Copper, tapping, welding, staking and mechanical assembly.

We have also integrated a number of complementary precision metal forming and metal joining processes such as in-die welding and in-die tapping and riveting into the stamping operations to reduce costs in certain applications.

Our Stamping Capabilities

Tooling
Our in-house tooling capabilities include engineering solid model designs, CAM packages for linkage to CAD, modern CNC machining on various equipment, grinding and wire-cut EDM techniques to produce carbide, steel or ceramic tooling designed to meet exacting specifications.

Prototype Tooling
Our prototype tooling capabilities include design and production of prototype tooling for tight-tolerance precision metal stamped components, larger components such as enclosures and assemblies, as well as short run volumes. This is especially appropriate for the production of both prototypes and low volume overmolded or molded and assembled plastic/metal components.

Precision Metal Stamping
Our full suite of precision metal stamping capabilities includes:

  • High-speed stamping
  • Horizontal cold forming
  • In-house manufacture of carrier tape pockets with manual and automated equipment to place stamped parts into carrier tape
  • Multi-slide stamping
  • Micro metal stamping
  • Precision cold forged progressive stamping
  • Progressive stamping
  • Precision deep drawn stamping
  • Robotic transfer
  • Reel-to-reel stamping
  • Single-stage stamping
  • Sheet metal fabrication
  • Tape and reel packaging

Selective Tipping
We provide in-house reel-to-reel selective coating of epoxy.

In-Die Assembly
In-die assembly (within a progressive stamping tool) of metal components within a progressive die is possible, such as rivet-type contact insertion, staking and mixed metal assembly for spring and terminal assemblies, as well as circuit and terminal assemblies.

In-Die Tapping
Mostly suited for high-volume applications, in-die thread tapping of stamped components produces more consistent products, while reducing tool cost and piece price.

In-Die Welding
We can fully automate the precision high-speed welding of round or flat wire, shaped tape and precious metal contacts.
