A volumetric dosing unit ensures that the hot melt material is constantly and correctly extruded. The entire extrusion process is monitored and controlled by easy to use and intuitive software, which manages the thermo-regulated sensors and resistors throughout the system. Precisely managing the temperature of the product and therefore its viscosity is necessary to the performance and quality of this platform.

The thermoplastic spacer applicator Art. TA has been developed based on two key principles: efficiency and productivity. The operator interface includes all of the most widely used work programs with specific options for thermoplastic products. The product is pumped from its drum to the recirculation units, that work in unison to deliver continuous product extrusion. The benefits of this system configuration are particularly clear when the product drum needs replacing. A temperature monitoring system, with multiple thermostatically controlled sensors are positioned throughout the entire extrusion circuit and ensure the quality of the products extrusion.
