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.

IT’S 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

NOTe: No female die change was necessary for any of the above forming examples. However, bends of this type may cut and otherwise reduce the life of the Acroform™ pad.

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.

NOTe: Bends will generally have little or no springback and you may find that standard over-bend punches can be replaced with accurate male punches.

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.

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

SPeCIAl NOTe: 2" Acroform™ forms all 90° and 30° bends normally requiring smaller die openings. For short flanges and smaller press brakes, particularly in gauge stock, 1" is adequate. Because applications of Acroform™ vary, it is not possible for us to predict precise results covering all cases.

Acroform™ Inserts: It’s as simple & economical as it sounds!

ACROFORM™

fIGurE: ANORMAl APPlICATIONS

fIGurE: BFor long dies or

severe applications

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.

Acro-Hyde™ for Press Brake FormingAcro-Hyde™, a urethane film, prevents die marks on a wide range of materials including stainless, aluminum and other polished stocks. Manufacturing costs will be reduced signifi-cantly because the film eliminates secondary polishing or having to scrap expensive blanks. Simply cut Acro-Hyde™ to length, lay it on top of the bottom die and secure one side with *Double-faced Clamping Tape.

For a quick and effective way to avoid die marks on stainless steel, pre-painted 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.

This product is stocked in K•950A. It is available in softer grades.
