We offer precision sheet metal bending and folding for quality part production

Penbro Kelnick is highly experienced in the sheet metal bending industry for many years. For swift and repetitive precision sheet metal bending, we have invested in three press-brake machines. The Amada NC controlled 3-axis press brake, the RG35S and the RG135 with a sheet metal bending range of 1250mm and 3000mm respectively.

Our flagship press-brake is the Trumpf 320 ton NC controlled 5-axis, which has a bending range of 4000mm, and is capable of complex and multi-angle bending.

All enclosures for our various products including our battery cabinets, control panels, inverters, power supplies, load banks, etc are manufactured by Penbro Kelnick.

What is Sheet Metal Bending?

Bending is a metal manufacturing process that bend sheet metals into V-shapes, U-shapes or channel shapes. Equipment used for Metal Bending includes box and pan brakes, brake presses and specialised machine presses.

There are three types of metal bending when using brake presses. Air-Bending, Bottoming and Coining. Each of these types of Metal Bending is defined by their relationship between the end tool position and the thickness of the material.

Air Bending is a method that forms material by pressing a punch into a material, forcing it into a bottom V-die. The V-die is mounted on the press. A disadvantage of Air-Bending, however, is that it is not as precise as other methods. Yet Air-Bending uses fewer tools, higher productivity and lower costs! In some newer bottom tools, it can also be adjusted.

During the process of Bottoming, metal sheets are forced against the V opening. Bottoming produces precise metal bending and fewer spring-backs. For each bending angle, however, a different tool is needed.

Coining is a method that forces material into the bottom die with five to thirty times more force, than with Air Bending. Coining results in a permanent deformed metal sheet. Although Coining ensured high precision, it is accompanied with high costs.
