tpr塑料注射成型工艺：

根据材料的特性和进料条件，一般情况下，成型前应对材料的外观和工艺性能进行测试。供应的颗粒通常含有不同程度的水分、助焊剂和其他挥发性低分子，尤其是具有吸湿倾向的TPR的水分含量总是超过加工的允许限度。因此，加工前必须干燥，并测定水分含量。TPR在高温下的含水率低于5%，甚至2%~3%，因此，常用的真空干燥箱在75℃~90℃干燥2小时。干燥后的材料必须妥善密封，以防材料从空气中吸收水分而失去干燥效果，为此，干燥室料斗可以连续为注塑机提供干热材料，有利于简化操作、保持清洁、提高质量和提高注塑率。装料机的装料能力一般是注塑机每小时的2.5倍。SBC基TPE在颜色上优于大多数其他TPR塑料材料。因此，它们只需要少量色母粒就可以达到一定的色彩效果，而且所产生的色彩比其他TPR更纯净。一般来说，色母粒粘度应低于TPR粘度，因为TPR熔融指数高，这将有利于分散过程，使颜色分布更均匀

TPR plastic injection molding process:

According to the characteristics of the material and the feeding conditions, Generally, the appearance and process performance of the material should be tested before forming. Particles supplied often contain varying degrees of moisture, fluxes and other volatile low molecules, Especially, the moisture content of TPR with hygroscopic tendency always exceeds the allowable limit of processing. Therefore, It must be dried before processing, And the water content was determined. TPR moisture content at high temperatures is below 5%, Even 2%~3%, Therefore, the commonly used vacuum drying box at 75℃~90℃ drying for 2 hours. The dried material must be properly sealed, In case the material absorbs moisture from the air and loses its drying effect, For this purpose, the drying chamber hopper can continuously provide dry hot material for injection molding machine, It is beneficial to simplify operation, keep clean, improve quality and increase injection rate. The loading capacity of the drying hopper is generally 2.5 times that of the injection molding machine per hour. The SBC – based TPE is superior in color to most other TPR plastic materials. So, They only need a small amount of color masterbatch to achieve a certain color effect, And the color produced is more pure than other TPR. In general, Color masterbatch viscosity should be lower than TPR viscosity, Because TPR melt index is high, This will facilitate the decentralization process, Make the color distribution more uniform.
