Tool

The efficiency of extrusion depends to a large extent on the performance of the tooling, in particular on its service life. The durability of the extrusion tooling is influenced mainly by the following four factors:

• Tool design
• Material selection and heat treatment
• Tool manufacture
• Working conditions

These are clear criteria for the competence and selection of a partner. The alloy steel specialist TRAMAK is recognised worldwide as a leading supplier to the extrusion industry. TRAMAK has acquired extensive expertise over a number of years through innovation and reliable products that go far beyond the criteria in this branch of industry. Based on many years of cooperation with the extrusion industry, TRAMAK is regarded as a problem solver and partner that can be relied upon for sound advice.

TRAMAK specialist engineers are internationally involved in the development and design of new tools and processes.

The material selection depends primarily on the following factors:

• Material being extruded (aluminium, copper and copper alloys, steel)
• Press temperature (up to 1000°C, partly long contact times)
• Extrusion program/press sequence
• Billet dimensions
• Type of press
• Extrusion speed
• Press power
• Extruded profile
