Tooling Design and Manufacture for CRE Machines

连续旋转挤压机(CRE)用于挤压以铜、铝及其合金为主的有色金属的高质量连续型材。电力行业是使用CRE制造的产品的主要用户，例如母线型材、高压电缆的电导体、避雷针、铝包钢线、电机和变压器部件。工具磨损率是一个关键因素(也是挤压过程的成本组成部分)，尤其是对铜型材的挤压。全球唯一一家全套CRE生产线(包括零部件和工装)的全集成供应商Meltech CRE Ltd发现了新CRE机床设计和制造工艺的市场缺口，以便在全球范围内竞争。

Continuous Rotary Extrusion (CRE) machines are used to extrude high quality continuous profiles in non-ferrous metals, predominantly copper, aluminium and their alloys. The electrical industry is a major user of products made using CRE, e.g. busbar profiles, electrical conductor for high voltage cables, lightning conductors, aluminium-clad steel wires, motorand transformer components. Tool wear rate is a critical factor (and cost component of the extrusion process), particularly for the extrusion of copper profiles. Meltech CRE Ltd, the world’s only fully integrated supplier of complete CRE production lines (including spares and tooling), has identified a gap in the market for a new CRE machine tool design and manufacturing process to compete globally.
