Plastic extrusion product material selection
Not all thermoplastics can be processed by extrusion molding. Common base materials include hard materials and elastic materials. Hard materials: PVC, PC, PETG, ABS, PP, HIPS, PMMA, LDPE, HDPE, POM, ASA, PA, AS, EVA, PC+ABS, etc. Elastic materials: PVC, TPU, TPE, POE, TPR, TPV, TPEE, etc..
Uniform thickness of plastic extrusions
As with the design of injection molded parts, aluminum extruded parts, etc., uniform wall thickness is critical. If the wall thickness of a plastic extrusion is not uniform, with some parts thick and some parts thin, this allows the plastic to flow unevenly as it is extruded in the mold, resulting in different cooling rates and ultimately distortion of the part. If distortion needs to be controlled, additional cooling processes are required, making the line less efficient and more expensive to produce
Design of rounded corners
Sharp corners on extrusions can turn the sharp corners into a weak point in the extrusion due to stress concentration, which is prone to cracking or failure, and can reduce the impact resistance of the extrusion. In extrusions, sharp corners should be avoided as much as possible, and rounded corners should be added at the sharp corners with a radius equal to the wall thickness of the product, which helps the material flow more smoothly during the extrusion process and reduces the stress at the corner of the profile.
Plastic co-extruded products
Co-extrusion is the simultaneous extrusion of two or more materials combined in the same extrusion between the cooling of the extrusions. It is possible to combine two different colors in the same extrusion, or to produce a two-color extrusion with a primary color and a second color stripe. It is also possible to combine a hard material and a material with flexibility in the same extrusion, which allows a rigid extrusion to have a flexible lip or flange, or allows two rigid extrusions to be joined by a flexible hinge.
