The design of plastic extrusion die extrusion thermoplastic elastomer extrusion die includes the design of geometric parameters (such as wall thickness, reinforcement, radius, hollow and hinge), and the effect of them on the processing and performance of the product should be considered. The general guidelines for extrusion design are listed below.
Wall thickness
Uniform or nearly uniform section thickness will be easier to process, reduce costs, better error control, better surface finish and more complex shapes. The minimum wall thickness is 0.5 mm (0.02″), while the maximum wall thickness is 9.5 mm (0.375″). A thinner wall thickness is possible, but santoprene8000 thermoplastic elastic system column is needed. The change of wall thickness should be smooth and smooth, and should be as small as possible, because this will help stamping die balance.
Reinforcement
In the process of wall thickness change, if the thickness change is too intense and too large, problems may occur in the process of balancing the flow field. The thickness of the reinforcement should be 50% of the nominal wall thickness, and the radius should be designed on this basis.
Rad radius
The sharp changes should be replaced by rounded corners. Extrusion parts have a minimum radius mm(0.007″).0.20
Hollow
There may be hollow sections in the cross section. The extrusion die may have the shape of hollow section at the beginning. When cooling, compressed air can be used in the hollow section to keep the shape. Another way is to use vacuum outside the extruder to help the hollow section to keep the shape. More hollow sections make the design of the die more complex and the shape of its contour more difficult to maintain. Except for design requirements, hollow sections should be minimized or even avoided altogether.
