Extrusion method of 6063 aluminium sheet

Extrusion method of 6063 aluminium sheet

By automatically adjusting the extrusion speed to keep the temperature of the deformation zone of 6063 aluminium sheet within a certain constant range, it can achieve rapid extrusion without cracking, and with the extrusion, there is no isothermal extrusion control system, high-speed extrusion will make the actual temperature of extrusion grow substantially, that is to say, there is no isothermal extrusion and isothermal extrusion control system, the speed of the products out of the material is not consistent, the surface of the extruded products will The surface of the extruded products will appear ripples or even cracks in the extrusion defects, so as not to achieve rapid extrusion.

Next we talk about the requirements of 6063 aluminium sheet on the discharge method. Products from the die out of the mouth, in order to ensure that it can be extruded along the centre line of the longitudinal balance and fast forward, there must be traction machine traction, preferably double traction. Without traction machine traction, the rapid outflow of the product surface may appear similar to the water ripple defects, or will make the product local bending, or even blocked discharge.

What other new processes are available for rapid extrusion of 6063 aluminium sheet? Fast extrusion extrusion speed can generally be increased to the general extrusion speed of 2-4 times, experts through the efforts of more than a year, there are now a few die extrusion speed has reached 60m / min above, to achieve rapid extrusion. Compared with general extrusion, the process requirements of rapid extrusion are more stringent.
