Wireless Switchgear for Two-Component Injection Moulding

Wireless, not cabled: according to this principle, wireless switches and sensors fromsteuteguarantee safe, reliable and cable-free signal transmission in a wide range of applications. One interesting area for this solution is plastic injection moulding, especially multi-component processes which often involve machines with rotary plates. These plates enable the main part of the construction element to be moulded first and then—after rotating the plate by 90 or 180—injection of the second part. This prevents distortion and accelerates the production process.

这里的一个挑战在于监控滑动位置，从而最终闭合注塑工具。如果幻灯片不在正确的位置并且工具关闭，这会导致维修，这不仅是金钱，而且 - 几乎更重要的是。

为了防止这种情况发生，虽然同时消除了安装电缆的努力，那么也易于磨损和撕裂，用户可以选择从慢脱的无线位置开关或无线电感传感器。无线开关或传感器将载玻片的结束位置注册并将相应的信号发送到控制柜内的无线接收器单元。在接收器单元将信号“滑动闭合”发送到机器控制系统之前，未启动下一注射成型过程。

因为这种解决方案是最优雅的方式（安装和没有磨损和撕裂），实现从旋转机器元件实现信号传输，它已经通过领先的塑料处理器使用。其中大多数已经选择了来自慢弦范围（例如，ES 13）的位置切换，然后与无线通用发射器（RF 96 ST或RF I / O）组合“无线兼容”。或者，来自RF的无线电感传感器也是可用的。

The cost of installing a wireless switch or sensor (including receiver and integration in the machine control system) is very manageable, whereas the benefits are enormous, due to the fact that this option is a very simple and reliable way to avoid tool damage. Incidentally, similar solutions are also in use for metal processing—for example to monitor the positioning of workpieces in press brakes.
