Ready to take the plunge into transfer work? MetalForming talked to Pat Cullen, sales manager for HMS Products Co, (www.hmsproducts.com), Troy MI, a producer of mechanical, servo-mechanical and all-servo transfer equipment. Here's his take on how stampers can choose the right transfer system. Mechanical and servomecfaanical-Today's purchasers of mechanical and servomechanical part-transfer equipment fall into these groups: Manufacturer of a specific product-This metalformer, with contracts to produce a specific part such as valve cover or lawnmower gas tank in high volumes, is a perfect candidate for all-mechanical transfer systems. Contract stamper that produces a series of parts with common sizes and geometries-If the volume is sufficient on two or three parts that are extremely similar in size, shape and required forming steps, this stamper can buy a mechanical transfer system and just change the tooling from part to part to part. If transfer timing does not need to change from part to part, the stamper can run the same transfer-system cams and only change the tooling elements.
