MANUFACTURING PROCESSES

We draft and implement all manufacturing processes for the production of top-quality components. This includes highly sophisticated engineering methods, pre-emptive maintenance as well as high-grade examination and testing strategies. Pipe forming, pipe connecting and joining using welding, soldering and other connection techniques are continuously being developed further and today constitute one of our core competencies for the implementation of sophisticated customer applications.

Manufacturing processes

BENDING

Pipe forming constitutes one of our core competencies. Using modern CNC pipe bending centres we ensure that our products live up to the most demanding quality requirements. Our production processes are fully automated and linked to optical 3D measuring of the formed pipes so that our customers benefit from all available efficiency and quality advantages.

END PROCESSING

The required shape, surface and material properties of a pipe end always depend on the respective product application. Here, smart selection of the correct forming method is tantamount so that not only all requirements are met but also cost targets are reached. In our facility we offer both conventional axial and rolling pipe forming. Using rolling pipe forming plants, we are capable of producing sealing elements with sharp edged contours and exceptional surface properties. Apart from technological advantages, this method also harnesses enormous cost saving potential because rolled pipe ends render cost-intensive rotating parts obsolete.

HYDROFORMING

Due to the dynamic stress during use, media-conveying pipes frequently require what is referred to as de-coupling elements. These elements can be implemented using hoses or wave packets. For thin-walled pipes wave packets are advantageous. In addition to significantly enhanced temperature resilience compared to hoses, wave packets provide another crucial advantage: The shape is created directly in the pipe so that no further joining sites and corresponding assembly steps are required.

SOLDERING AND WELDING

The welding methods used are state of the art (MIG; MAG; WIG, CMT) and serve to fix the components to be joined for subsequent soldering. In order to live up to our customers’ specifications, our components have to fulfil high resilience and tightness requirements. The method for thermally joining the parts is selected and adjusted depending on the functionality of the component, the materials used and so as to ensure a stable manufacturing process. The solder joints are created in a conveyor oven under protective atmospheric conditions and using a stable copper soldering procedure.

FINE BLANKING

We use fine blanking as our manufacturing method for chip-less separation and simultaneous forming of parts made from metal tape with high precision, small tolerances and almost burr-free cutting edges. With this technology, we can manufacture highly precise mounting parts in-house, using Finetool devices with 200 – 630 t pressing force. This fine cutting technology is suitable for almost all types of metal, as a general rule we use special steels and high-alloy stainless steels. The high degree of precision of our tools and our in-depth knowledge of the deformation properties of the materials used are major influencing factors for our successful use of this technology.

ASSEMBLY

Only when assembled, individual components turn into bespoke construction parts or assembly units. Apart from a high degree of automation, reliable procedures are of particular significance in our assembly processes. By integrating sensors and measuring technology into our assembly stations, we are able to both satisfy our customers’ quality requirements and also our own expectations regarding reliable production processes. Moreover, all our parts are subjected to a 100 % functionality check at the leak test units.
