Crimper first
November 2019

BDC Aluminium has become the first fabricator in the UK to invest in a new 4-head Ever Theta frame crimping machine from Fom, supplied by UK authorized supplier PROMAC GROUP.

The Ever Theta cuts full-cycle times to as little as 2 minutes and 31 seconds – roughly half the time it takes using a traditional single head crimper. It also offers flagging out of tolerance profiles of as little as 0.4mm out in length or 0.9mm on the diagonal for 45° mitre and 90° joints.

David Green, managing director of the Smart System fabricator, said: “As a process crimping is highly reliant on the individual operative. They have to set up, run a test, scrap it if it’s not right, set it up again. On a window you’ve got the frame and sash, so that’s two set ups, two potential errors, and the biggest cost by a mile – time”

The Ever Theta can be used in the manufacture of frames of as little as 320mmx400mm and up to maximum frame dimensions of 2600x1100 mm; 2600x2000mm; 2600x2900mm; 2600x3800mm; and 2600x4700 mm. The maximum crimping height is 160mm. 

Automating the crimping process, it operates across 21 CNC axes and has been designed for use in the manufacture of all types of frames, delivering a highly accurate and repeatable crimp. 

It delivers this through an in-built profile and panel dimension measuring system. This allows it to scan the profile against maximum tolerances. As the infeed conveyor passes the frame along the line everything is again measured, guaranteeing quality of joints and squareness of frames.
