The ASCON range can process starting material up to 26mm in diameter

Innovation in extrusion The engineers at mechanical engineering firm ASMAG have been dealing with the continuous extrusion of copper and aluminium products for almost 30 years.

increased, and the tools’ service life is extended. Fast tool set-up times of less than five minutes from good material to good material offer a high degree of flexibility, which is of particular benefit in small batch production. One ASMAG customer who already oper ates a complete line is enthusiastic about the ASCON products: “We got involved with energy- and resource-efficient production at an early stage. However, our expectations were far exceeded. With the recently acquired second ASCON, we will cover a rapidly growing market.” ASMAG GmbH www.asmag-group.com

“The three main criteria for the new development of the ASCON machine series were to construct a very robust system that enables the flash to be adjusted under load and at the same time enables the shortest possible tool setup times,” said a spokesperson for the ASMAG development team. “This has resulted from close cooperation with our customers.” The design of the ASCON machines enables high forming forces. Very wide and thin strips, which are currently produced by conventional methods, can be produced economically. A special system allows adjustment of the flash under load. As a result, the productivity of the entire system is

Owing to high customer demand for environmentally friendly and flexible product manufacture, a separate range of machines was designed. Standard round wire, as the starting material, is fed to the system via a straightening section. Depending on the size of the system, this can have a diameter of up to 26mm (1"). Using high force in the main machine body, the raw material is brought into any desired final shape, such as flat material, round material or profiles.

New conical crosshead for MV and HV cable production

Maillefer’s new addition to its conical crosshead range – THC 50/90 – is a solution for medium- and high-voltage cable production. It features optimised bi-flow distributors to enable accurate wall thickness, centricity and roundness of the cable. Short residence times, streamlined flow channels and efficient water tempering allow long production lengths and smooth layer surfaces. The centring of all layers can be adjusted independently. Conical flow pieces are made of nitrided steel to ensure continuity in production. The crosshead is suitable for three-layer extrusion for MV and HV insulations up to 132kV. It enables a wide production range, with fast set up, and easy handling with low damage risk. Maillefer Extrusion Oy www.maillefer.net
