Straight components for curved projects<\/h1>\n

Krehle GmbH uses Schr\u00f6der folding machine<\/h2>\n

Krehle GmbH is known for its high-quality round metal profiles for roofs and facades. From Copenhagen to Ashgabat in Turkmenistan, they make the hearts of architects and roofers alike beat faster. As a manufacturer of ready-to-install solutions, Krehle supplies not only the curved profiles but also all necessary straight connecting parts and covers. With the new PowerBend Professional folding machine, these components are manufactured quickly, efficiently, and with precise dimensions. (https:\/\/krehle.de\/)<\/p>\n

This is an area where we can improve even more<\/strong><\/p>\n

Ensuring the high quality standards that Krehle customers have come to expect from round profiles\u2014even for straight profiles\u2014was becoming increasingly difficult with the aging folding machines in the company\u2019s machine park. Rework was often necessary, for example to remove indentations or compensate for dimensional deviations.<\/p>\n

At a trade show, Michele Dal Ponte, a technician at Krehle, became aware of the Schr\u00f6der Group\u2014specifically a swing-bending machine with a rotating clamping beam: \u201cWe looked at various manufacturers, scheduled on-site visits, and compared the machines with identical bending tests. One factor was decisive for us with Schr\u00f6der: repeatability. It is extremely important to us, as we rely on reproducible dimensions. This allows components to be assembled without additional adjustments.\u201d<\/p>\n

When the Krehle employees first got to know the PowerBend Professional at Hans Schr\u00f6der Maschinenbau in Wessobrunn-Forst, some aspects were initially unfamiliar, such as the pneumatic clamping of the folding beam tools. In practice, however, this concept proved itself just as much as the other technical details. Krehle brought its own requirements to the back gauge fingers, for which Schr\u00f6der implemented a suitable custom solution.<\/p>\n

Opportunities identified and seized<\/strong><\/p>\n

Krehle uses the PowerBend Professional model capable of folding steel sheets up to 2.5 mm thick with a working length of 4000 mm. In addition, materials such as aluminum, copper, and zinc with thicknesses ranging from 0.5 to 3 mm are processed.<\/p>\n

The machine produces all straight connecting parts, butt joints, brackets, and special components to complement the round profiles. But that\u2019s not all: increasingly, complete assemblies consisting of round and straight components are being delivered together.<\/p>\n

\u201cOriginally, many customers had the mindset that Krehle manufactures the round profiles, while they produce the straight components themselves,\u201d explains Managing Director Eva Krehle. \u201cHowever, since we can produce very quickly and with high precision on the Schr\u00f6der machine, customers are happy to accept our offer to also source the straight components from us. Thanks to the high efficiency, this can be implemented in an economically attractive way.\u201d<\/p>\n

Customers receive complete, ready-to-install deliveries directly to the construction site and benefit from shorter installation times, less effort, and reduced costs.<\/p>\n

Advantages of a Powerful Control System<\/strong><\/p>\n

Today, Krehle supplies not only round and straight wall copings, facade profiles, and window flashings, but also increasingly complex custom solutions. \u201cWe first had to familiarize ourselves thoroughly with the comprehensive control system of the PowerBend Professional,\u201d reports Krehle skilled worker Michael Muth. \u201cBut the effort is worth it. It\u2019s fun to program components that you wouldn\u2019t have thought were feasible before.\u201d<\/p>\n

The segmented top rail tools are particularly helpful here, for example when setting up different stations. Thanks to the rotating clamping beam, complex profiles can be produced without constantly retooling the machine. Another process improvement is that data from round profile production can be easily transferred, and matching connecting parts can be created directly in the folding machine\u2019s software. The programs remain saved. The time-consuming search for drawings is eliminated.<\/p>\n

\u201cThe accuracy of the PowerBend Professional is a key factor in our ability to consistently meet our high quality standards today, even for straight components,\u201d says Managing Director Eva Krehle. \u201cDimensional accuracy is crucial, especially when combined with our round profiles. Schr\u00f6der\u2019s technology is at the cutting edge. The investment has clearly paid off for us.\u201d<\/p>\n
