Jigs, Casting Dies, Die Casting Moulds & Moulding Tools #4956865

Bend Tooling supplies the entire package for rotary-draw tube-bending. Manufactured with Datafacturing , the most advanced machining technology in the industry, our new generation of Shockmate die sets are unsurpassed in fit and finish. Plus, these tools are tough!

A rotary-draw die set has three components: Bend die, clamp die, and pressure die. The key material requirement for these dies is that they are tough. A tough die has hard working surfaces that can absorb a shock without breaking. So a tough die has some give. It is not brittle. For the same reason we do not use glass hammers, we should avoid materials and heat treatments for bending dies that make them brittle instead of tough and so break instead of wear out. Consequently, the tool steels that are sometimes specified for rotary-draw die sets, such as A2, D2, or even a shock-resistant material like S7, are not the best materials in terms of cost-effectiveness. While they can be heat treated to a high level of hardness, they are designed to hold a sharp edge in metal-cutting operations. So the brittleness that comes with this hardness is acceptable for that use. However, tube-bending is, of course, not a metal-cutting process. There is no need for tooling materials that hold a sharp edge.

Bend Tooling's industry-leading inserted wiper die is our most popular product. Over the past twenty years we have perfected the design and manufacture of our inserted wiper line, and no one else comes close to our quality, price, and speed of delivery. We also manufacture traditional "aircraft-quality" square-back solid-body wiper dies plus we have a resharpening service for these tools (including those made by our competitors). Square-back solid-body wiper dies are excellent for high-pressure tube-bending jobs that require the wiper to be set at zero-rake. However, they are relatively costly to purchase and then recondition as they wear. Consequently, Bend Tooling has introduced a new wiper product, our patented High-Pressure Wiper System (U.S. Patent No. 20080202189-A1). This new tool combines the best features of a traditional solid wiper and a modern inserted wiper for cost-efficient high-performance for high-pressure rotary-draw tube-bending. If you are bending stainless steel, titanium, Inconel, or tight-radius tube bends, ask us about this effective alternative to solid square-back wipers.
