Plastic profile extrusion molding planning considerations. In the planning of extrusion molding of plastic profile, special attention should be paid to the uniformity of wall thickness, fillet and stiffener. If there is any omission, it will lead to irreparable defects. Li, chief engineer of the plastic molding Research Institute of Tsinghua University, also pointed out that the planning of plastic products is very different with different cooling and setting methods. Let's take a look at the th

The coextrusion of PVC profiles and multicolored surface layers is one of the most popular coloration methods for PVC profiles in China. From 2002 to now, the development trend of producing colorful profiles by CO extrusion is rapid, accounting for about 40% of the sales market of colorful profiles, and it is estimated to reach 80% in 2020. By using coextrusion technology, the milky white PVC profile can be colored, and the aging resistance, temperature resistance and impact resistance of the PV
