Plastic profile extrusion die is a core part of the extrusion of plastic profile extrusion die technology status is directly related to the stability of extrusion and extrusion products of quality PVC plastic profile extrusion production efficiency and service life of the mold itself. Therefore, plastic profile extrusion die proper use and maintenance is very important. Plastic profile extrusion die after the arrival of the box to check the box to check PVC plastic profile processing, packaging intact: Remove the packing list of technical documents, brochures, etc. use out of the box, according to an inventory of the contents of the packing list for the formation of the whole mold , accessories, special tools. Plastic profile products use more: window frames, stair handrails, trunking, skirting boards, shaped and so on. The main raw material is hard PVC, few are semi-rigid PVC, soft PVC, polyurethane foam and other materials low. PVC melt temperature during processing is a very important process parameters PVC plastic profile manufacturer, if this argument would lead to inappropriate material decomposition problem. PVC is rather poor flow characteristics, the process is very narrow range. Especially high molecular weight PVC material more difficult to process (this material is usually added to improve the flow characteristics of lubricant), it is often used are low molecular weight PVC material. PVC contraction rate is very low, typically 0.2 to 0.6%. Injection molding conditions melting temperature: 185 ~ 205 ℃ mold temperature: 20 ~ 50 ℃ injection pressure: can be as large 1500bar holding pressure: can be as large as 1000bar injection speed: To avoid material degradation, the general use of the injection speed considerably.
