injection molding processing 时 raw materials how to Color Matching color can using/adopting color powder add resin method and color masterbatch method.  
　　 color powder and plastics resin mixed combined rear, lower products molding process, short, cost low, as ring 境差, color force 差, color uniform property and quality stability property 差.  
　　 color masterbatch method is color agent and resin, dispersant, other additives made formed concentrated degree color agent material, products molding according to color requirements, add 入一定 amount color masterbatch, make products has requirements color agent amount, to color requirements.  
　　 color masterbatch can color resin classification, 如ABS color masterbatch, PC color masterbatch, PP color masterbatch and other; can color resin processing classification, has injection molding, film, extrusion grade large type masterbatch. color masterbatch due to for material 先进行预处理, has relatively high color force, use amount can reduce quality stability, 运输, 贮存, use 方便, ring 境污染 large is reduce.  
　　 dispersant through for material lubricating wet, troubleshooting surface gas, will poly 体, poly dispersion formed fine micro, stability and uniform pellets, in processing process in again poly, commonly used dispersant is low molecular weight polyethylene wax, for/regarding relatively difficult dispersion has machine material and using/adopting EVA wax or oxidized polyethylene wax, combined formed low molecular weight polyethylene wax and polyethylene (PE) understanding method made low molecular weight polyethylene wax has very large 差别. other additives has coupling agent, antioxidant, light stabilizer, anti-static agent, filler and other, requirements and product types add amount, is more functional masterbatch, again add light agent, has 利于模塑 products demolding and improve/increase products surface light degree.  
　　 color masterbatch property can indicators has Color Difference, degree, degree, yellowing degree, heat stabilized property, oxygen index (LOI), melt flow rate and other, 当然颜 material fine degree, property, chemical resistance, property and color masterbatch property can has 关, has indicators in applications in separation important, fiber grade masterbatch pressure value （DF value ） fine degree.  

electrical Color Matching:  
　　 utilizing machine 进行调 color formulation and its tube/pipe already formed used for plastics Color Matching color.  
　　 electrical Color Matching tool has lower function:  
　　　　(1) Color Matching according to requirements commonly used 颜（染） material data 库（ made 备基础 color sheet/plate 并输入）. rear in soft parts mono lower material color sheet/plate electrical 脑, in in 点出数 候选颜 material, 立刻计算出一 series formulation, separation Color Difference and price 排序列出, Color Matching selection;  
　　　　(2) formulation positive positive electrical 脑列出 formulation, other formulation, Color Difference combined utilizing device 显示 不一致 反射曲线直接 through increase decrease material amount, 直至两 strip/profile basic heavy combined, positive rear formulation;  
　　　　(3) color amount and Color Difference control amount color agent color strong/high degree, product degree, product color degree, color Color Difference. due to electrical can amount table/sheet color property can indicators, has di 方 信息沟通 and 传递;  
　　　　(4) color tube/pipe day as in color 样, formulation, process conditions, production day and use and other 信息均 can 存入计算 machine, 便于检索, and as is 修改时 参考, 方便, fast 捷, improve/increase as efficiency, 且便于保密.
