SHL-Alubin is the biggest light metal extruder in Israel, with a monthly output of about 1,000 tonnes. Currently, the company primarily uses soft alloys in their production. The main thrust of an ongoing recent research and development project within the organisation is to upgrade one of their three presses to optimise the extrusion of hard alloys such as the 7000, 5000 and 2000 series.

Companies extruding hard alloys typically have a problem with temperature during the extrusion process, due to the necessarily slow ram speed. The objective of this R&D project is to introduce a special production system that will satisfactorily resolve this problem, and also improve extrusion speed, dimensional stability of the profile, and surface finish.

Castool Tooling Systems, based inUxbridge Ontario, is well-known as a leading global supplier of extrusion tooling. It has worked closely with SHL-AIubin on a number of smaller R&D projects over the past.15 years. In this venture, a significant purpose of the research is to accurately quantify the effect of Castool tooling components working together as a system in the production of close-tolerance hard-alloy profiles. The system will include single-cell die ovens, container, dummy block, clean out block, stem, boron nitride lubrication, visual optimiser, and cooling quench.

This joint R&D project by Castool and SHL-Alubin will be funded in part by the Canada-Israel Industrial Research and Development Foundation.
