Tooling Design and Manufacture for CRE Machines

连续旋转挤压机（CRE）用于挤压有色金属的高质量连续型材，主要是铜、铝及其合金。电气工业是使用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、避雷导体、铝包钢丝、电动机和变压器元件。刀具磨损率是一个关键因素（也是挤压过程的成本组成部分），特别是对铜型材的挤压。Meltech CRE有限公司是世界上唯一一家完整的CRE生产线（包括备件和工具）的完全集成供应商，已经确定了新的CRE机床设计和制造过程的市场空白，以参与全球竞争。

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.
