Metal Stamping Facility
Interplex's heritage as a precision metal stamping supplier dates back to the company's origins in 1958. The company, considered one of the premier precision metal stamping suppliers, specializes 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 providing precision metal stampings, we maintain a robust internal tooling capability to assure 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 3D packages such as Pro E and SolidWorks. Each facility has surface grinding, programmable CNC centers, sinker EDM and wire cutting EDM technologies, in house to support our precision metal stamping operations.

Precision Metal Stamping

Like the company's other metal forming processes (Cold Forging, Die Casting, Sheet Metal Fabrication and Machining) Interplex's stamping operations utilize leading precision metal stamping presses (manual, progressive or robotic lines) including Bruderer, Kyori, Ingyu, AIDA, SEYI, PATEC, Yamada Dobby and V&O presses and Minster with sizes ranging from 5 tons - 800 tons. Materials used in the precision metal stamping process include Beryllium Copper, Phosphorous Bronze, Stainless Steel & Copper and Cold Rolled Steel with thickness ranging from 0.002" to 0.180". As a result, Interplex has the capability to provide metal stamping services and products for a wide variety of industries. These are complemented with a comprehensive range of secondary processes including tapping, welding, staking and mechanical assembly.

Ultra-Thin Metal Stamping

In addition to metal stamping, we have integrated a number of complimentary 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.

We also leverage on state-of-the-art metal stamping technology including precision cold-forged progressive stamping and multi-slide stamping, to continually exceed the limits of conventional metal stamping manufacturing processes.

Precision Cold Forged Progressive Stamping (or Progressive Cold Forging as it is also known) is an alternative process for stamping precision metal parts. Metal is progressively stamped and formed to close tolerances, allowing 3-D net shaped parts to be produced. Products that require miniaturised components and which retains their rigidity and stability would benefit from this technology.

This cold-form precision stamping process is designed to meet quality, cost and lead-time as it eliminates or reduces the need for secondary processes like machining, sintering, die-casting, MIM and assembly processes. Manufacturing lead-time is significantly reduced which in turn results in significant cost savings.

Our metal stamping capability is currently equipped with over 600 Metal stamping presses, precision high speed as well as normal and long stroke. The parts manufactured vary from tiny parts in material as thin as .05mm to larger frames and heavy duty metal components. Our precision metal stamping presses vary in size from 5 tons to 800 tons, and with speeds up to 1,500 per minute. In addition to presses and auxiliary equipment, our metal stamping capability is equipped for in process inspection with CPK analysis, as well as press mounted vision systems where required. Additionally there are aqueous cleaning systems, and atmosphere controlled ovens for heat treatment of beryllium copper and other requirements. Our stamping services also have skiving equipment to contour metal thickness and configuration as required.
