ASCON – The new generation
In the field of Continuous Rotary Extrusion (CRE) technology, ASMAG comprises a team of experienced engineering designers and process specialists with skills in all aspects of design, manufacture and installation of metal processing equipment. A dedicated engineering team is responsible for all aspects of the ASCON range of continuous rotary extruders. The team provides a significant collective experience in the industry, comprising an international breadth of knowledge and technology development in the metals, tube and bar markets. 
"Advanced process technology to meet current and future market needs."
The most common applications for continuous rotary extrusion are in the aluminium and copper industries. However, the range of materials that can be processed continues to expand through research and development projects, many of which are being led by ASMAG.
In general, the advantage of the ASCON technology is that it is designed for manufacturing products of continuous lengths, varying in complexity and application.
- Flat busbars and busbars with shaped profiles for power distribution in switchgears and switchboards
- Trapezoidal busbars as commutator profiles for electrical motors and generators
- Trolley or contact wire for overhead electric railway systems
- Round tubes, oval tubes and multiport tubes for condensers, evaporators and heater cores
- Sheating of soft cable cores for use in community antenna television cables, fibre optic ground wire cables and trace heating elements
- Cladding of high voltage electrical power cables, aluminium coating to high tensile steel wire
Efficiency
at its best
The continuous rotary extrusion process was developed in the early 1970s and was subsequently commercialised in the metal processing industry in the production of aluminium and copper products. It is an innovative process which makes use of rod or particulate feedstock instead of cast metal billets, as used in a conventional extrusion press.
In the radial extrusion process the feedstock is channeled into the continuous rotary extrusion machine which houses a rotating grooved wheel. Frictional pressure is constantly applied to the feedstock as it is processed by means of a coining roll. The groove in the rotating wheel is subsequently closed by tooling plates and the feedstock path is blocked by means of an abutment.
As a result of the continuous feed of the material, the abutment area experiences pressure by volume and high temperature due to shear forces, and the feedstock becomes plastic. The extrusion die acts as a pressure relief conduit, driving the plasticised feedstock through the die. The application of various extrusion dies with quick changeover capability allows production flexibility and the ability to produce a selection of different outputs, i.e. solids, profiles and tubes.
