Optalex are pleased to introduce the latest version of the eX-box Closed-Loop Isothermal Extrusion System, using a Pyrometer to constantly measure the outlet temperature of the die
Optalex are pleased to introduce the latest version of the eX-box Closed-Loop Isothermal Extrusion System To compete in the competitive global market extruders need to get as much as they can out of their presses which ideally should be running at maximum speed at maximum temperature possible without affecting the quality of the extruded profile

Because the billet being extruded heats up due to friction in the container as it is pushed through the press, the speed of the push has to be slowed down and this is typically reliant on skilled operators responding to temperature measurements at the exit of the die.
The Optalex eX-box uses a highly accurate Pyrometer to constantly measure the exit temperature and feed this signal automatically back to the press speed control allowing maximum speed throughout the push and maximum constant temperature at all times.
The advantages of this are numerous: Consistent and optimised quality from the start to the finish of each billet, 10-30 percent more throughput, reduced scrap, full data collection and reporting on every billet extruded, parameter recall each time a previously used die is loaded which reduces run-in time for the die, offline remote monitoring of process via Ethernet protocol.
The system can be installed on a press in around 3-5 days without interrupting production and for extruders working with alloys such as 6061/6063 pays for itself within a few months.
