The function of this Turla machine is to decrease the profile temperature through water spray or air or a limited combination of both on the aluminium profile being extrudedADVANTAGES
Through a PLC and frequency inverter you modulate the overall air flow from 0 to 100% and store this in a recipe connected to the die numer or profile code. This will be recalled once the same product is about to be produced.
The Quench mod. QA-H consists of two main parts:
High performance air-cooling of the profiles In the quench structure there are 3 upper air ducts powered by a single large air blowing station that feeds the three air nozzles located at the top, right and left of the profile. Through a PLC and frequency inverters it is possible to regulate the overall air flow from 0 to 100%, so that air delivery can be varied according to the shape, mass and symmetricity of the profile. Settings are created for each profile to optimize cooling and maximize extrusion speed. Built-in flaps will adjust the air flow from each of the three top air ducts (top, right and left). A dedicated air blowing station will provide the air inlet to the bottom part only. High performance water spray cooling Water spray nozzles are installed in rows all around the profile. Each side (top, bottom, right and left) is individually controllable through the PLC so that homogeneous spray patterns over the cross section of the profile can be obtained. The fixed lower part of the quench will take the water coming from the spray nozzles and will recycle it in the circuit system. A dedicated water network with a pump will independently feed the quench. Through this high-pressure pump and the selected type of nozzle, a water spray effect will be produced. Water spray nozzles can be changed to other angles and configurations.
