IR-1891 Heat Shrink Shuttle Machine

IR-1891 Shuttle Machine

The IR-1891 machine installs Raychem heat shrink tubing products onto small components, such as ring terminals, FASTON terminals, and small connectors. The machine has two workstations and a moveable head.

Each workstation is provided with supports for tooling fixtures that can be specified and ordered separately. These support the work pieces and locate the tubing products. The operator loads the work pieces into the fixtures on a workstation, confirms that the tubing products are correctly positioned and then slides the heat head into position before initiating the heating cycle. The IR-1891 heat shrink shuttle is provided with closed loop temperature control. The heat head is 'locked' into position by use of an electromagnet during the heating cycle. Our versatile portfolio of equipment for heat shrink tubing enables you to process the heat-shrinkable tubing products in an easy, efficient, and cost-effective manner. Developed in close collaboration with customers for general industry use, this equipment provides optimal heating temperatures, performance, and control. For example, it is suitable for use in a wide range of automotive applications – from sealing and protecting electrical splices to providing mechanical protection for fluid management systems in harsh environments.
