Equal pressure with every injection for consistent and accurate results. The TCS Automatic Injector with Built-in Furnace is used to melt TCS Unbreakable nylon and inject it into the flask. The furnace is built-in to the injector eliminating the need to move the hot Cylinder with Handle and Molten Resin from the Furnace to the Injector. One of the many benefits of this injector include a design that is intended for easy cleaning and maintenance of the unit, because it is inevitable that some thermoplastic residue will be released into the receptacle at some point throughout the use of the injector. It has 4 screws located on the plaque at the top of the machine, the screws are simply unscrewed to remove the cylinder, then the cylinder can be easily cleaned of residue. Additionally, this unit has a self purging system, eliminating the need for hammering out cylinders.
