The Acroform™ insert is made of a specially formulated urethane and is designed to fit standard female press brake dies. This composition does not compress, but flows to form the shape of the male punch, literally wrapping the material around the punch, providing a scratch-free, accurate bend.
Please take a look at our YouTube Demonstration. This will help explain a few common questions regarding Acroform™ and how is it properly used with various applications. Acroform™ can really save you both time and money when making different and complex bends.
Just simply slip “Acroform” into an existing female die (Fig. A). Acroform™ sizes correspond to the nominal steel die opening – 1″ Acroform™ fits 1″ wide standard die. Use approximately 2″ longer Acroform™ length than length of bend. If long bends are being made, simply butt Acroform™ ends together (Acroform™ is available in up to 4′ lengths) using two-faced tape in the female die to prevent Acroform from separating at the joints (Fig. B). Press or die misalignment is not a problem as it is with hard steel dies.
Remember no-marks on stainless, aluminum, vinyl coated stock and pre-painted stock. Cracking is reduced and in many cases eliminated when forming difficult materials.
The Fastest Way to Short Flange Bending
For Example try forming these flanges in steel dies:
- 5/16″ Leg, 90° Flange, 16 ga. M.S. 1″ wide “V” die
- 1/8″ Leg, 90° Flange, 24 ga. M.S. 1″ wide “V” die
- 1/16″ Leg, 90° Flange, .001″ Brass, 1″ wide “V” die
- 5/8″ Leg, 90° Flange, 10 ga. M.S. 1″ wide “V” die
For guidance of the tonnage required with 1″ Acroform™ and a 90° bend in M.S.:
- 20 ga. – 4 tons/ft. approximate
- 16 ga. – 6 tons/ft. approximate
- 14 ga. – 9 tons/ft. approximate
- 11 ga. – 20 tons/ft. approximate
For maximum life of Acroform™, use the least penetration that will produce the desired bend and generally do not penetrate to a depth of more than 30% of the Acroform™ height. *Clean Acroform™ to avoid abrasion.
The maximum thickness capacity of your female die remains approximately the same when using Acroform™, except that you can now also form thinner materials without changing the female die to a smaller size.

Acroform™ Inserts
For a quick and effective way to avoid die marks on stainless steel, prepainted material, etc. simply position these 1″ or 2″ inserts in corresponding 90°bottom dies! The K•Prene® insert will conform to a variety of punch tips. In addition to eliminating the secondary procedure expense of removing die marks, your die will now act like a universal bottom die. The forming of expanded metal or mesh is simplified, as cracking is reduced and often eliminated.
Acroform™ Inserts with a Hole
Indicated by * in the part numbers below: Our new design will help to reduce tonnage required for bending. This design is ideal for radius bends of up to 1/4″ radius.
This product is stocked in K•950A. It is available in softer grades.
