Together with Carlo Salvi, Hatebur is one of the world’s leading manufacturers of machines for horizontal cold and hot forming and will present the groundbreaking cold former COLDmatic CM 725 and the impressively fast Carlo Salvi CS 001 on its booth at this year’s wire® Düsseldorf.

Hatebur’s COLDmatic CM 725 is a seven station former designed for the forming of the highest precision parts with a length of 8mm to 125mm and a wire diameter of up to 22mm. With these specifications, the COLDmatic CM 725 is ideal for suppliers of the automotive industry.

“Our engineering team implemented several innovations to make our clients more efficient and productive. With a production capacity of up to 180 parts per minute, the CM 725 is much faster than previous machine generations,” reports Reinhard Buehrer, head of marketing and sales at Hatebur.

Hatebur has also minimised the changeover times considerably for the CM 725. Plus, at the wire infeed, a linear servo motor ensures that the grippers push the wire forward with the highest precision. In addition, the volume variation of the cut-off parts is below 0.35%. Together with the high-quality of the sheared surface, which is typical for the COLDmatic, this results in a cut-off quality that allows forming from the first station.

The centerpiece of the COLDmatic is the newly designed transfer system on which the grippers for the part transfer are mounted. All grippers are individually driven by servo motors and can be individually opened, and closed, as well as programmed. “This programmability brings enormous advantages when it comes to changeover times. Instead of changing all the parameters manually, all previously saved settings can be applied in just a few seconds,” explains Reinhard Buehrer. Because of the servo motors, the COLDmatic CM 725 uses much less mechanical parts than previous machines, reducing the overall cost by almost 20%. The innovative fast changing system allows operators to lift out all seven punches and dies at once and exchange them with prepared units. All tools can be exchanged in only ten to fifteen minutes.

As well as the COLDmatic CM 725, the Hatebur and Carlo Salvi booth will also highlight the Carlo Salvi CS 001, which will be in operation. The CS 001 is designed for very thin wires from 0.6mm to 3mm. With one die and two punches, it can form an impressive 660 parts per minute. The CS 001 also offers minimised set-up time and is easy to changeover and to operate – making it ideal for the production of screw blanks and solid parts. Even small quantities as low as 5,000 parts are profitable due to the minimised set-up time.
