Changshu smoothly da plastic products factory talk about plastic extrusion profiles and the importance of mouth mold materials

Through plastic extrusion mechanism of plastic material, the first use of raw materials for plastic material to cengcengbaguan, then critical process of mould processing, is correctly calculated and export mode cross section shape and the appropriate port. Changshu well below da plastic products factory to talk about plastic extrusion profiles and the importance of mouth mold materials.



first, raw material, if is used for making plastic different profile, need PA66 such insulation plastic different profile were selected as the raw materials for processing.



the assembly size plastic material products has a strict standard of tolerance, cross section shape design complex, wall thickness is also each are not identical. So, need to profile first carries on the preliminary test detection, gradually get profiles design size and various processing parameters.



plastic extrusion mold test to detect the mouth, is directly related to the correctness of the mold design, the mouth of the wrong mold design will affect the shape and size of plastic material products.



when the profile of the thick degree not phase at the same time, the thickness of high part will reduce the resistance in the flow passage, faster, and the thinner part may slow down because larger resistance and velocity, so the consequences of bending is thick, thin, craze, the profile processing is very bad, need raw material for cooling contraction of mould material, to ensure that doesn't make the profile thickness influence the mold production.



by plastic extrusion mold design of plastic material mouth size, shape and the change of flow linear flow, designed to meet the requirements of molding plastic material products.
