Press brake bending

Proshort provides press brake bending with the technical expertise to understand the ductility of the metal you need to ensure we bend it not break it. The ductility allows your metal to be versatile and therefore formed to intricate shapes and sizes for your rapid prototype or short run needs.

Common press brake bending applications we specialize in are panels, metal containers or housings, frames, brackets, hooks,metal parts, artwork and more.

Bending materials, such as sheet metal, require a large amount of accurate force via our press brake bending machines.

We are experts with coining, bottom bending and air bending to determine which press brake bending application is best for your type of metal being bent, the die, the punch and bending force for stainless steel, alloy steel, tool steel, aluminum, aluminum alloy, brass, bronze, copper, galvanized steel and more.

Understanding the press brake fundamental type of bending along with the bend radius, the amount a material can be bent without damaging it, is essential for quality parts. High carbon steel is less bendable by a press brake than aluminum alloys because of the ductility and strength differences.

There are three main press brake bending types, and several types of applying force methods:

Methods include mechanical, pneumatic, hydraulic, and servo-electric. The three-press brake bending types include:

“Coining” comes from the making of coins which uses a very high tonnage compress with enough force to conform the image inscribed on the die set. This process thins the metal by the impact of the punch and die, as it is compressed between them along the bending surfaces. Sheet metal can be bent to the precise angle of our tooling in order to obtain the exact angle you need.

“Bottom Bending” is when the punch and die are brought together. It differs from “coining” in that the punch and die do not make full contact with the metal and there isn’t enough force used to imprint or thin the metal. With bottom bending there is “springback” after the metal relaxes so tooling must be used.

“Air Bending” has even less contact than “bottom bending” and the material only touches the press brake bending machine at the punch tip and the die shoulders. This method allows a whole range of bend angles from one set of tooling.

We are your one stop shop with all our in-house services: laser cutting, press brake bending, shearing, milling, vibratory finishing, PEM insertion, forming, drilling, TIG welding & MIG welding, and painting. Combined with our our-sourced operations: plating, anodizing, powder coating and passivating services we are your turnkey prototype and short run parts provider.
