BMC brief introduction   （ full 名团状模塑 composite/compounding material ）
BMC(DMC)材 material is Bulk(Dough) molding compound shrink 写, 即团状模 plastics. inner as saturated and polyester 团状模 plastics. its main/primary raw materials 由GF（ short glass fiber ）, UP（不 saturated and resin ）, MD（ filler ）以 and various additives separation mixed combined formed material 团状预浸 material. DMC材 material 于二十世纪60 year in front and UK, 首先 以 application, rear in 70 year and 80 year separation in USA and Japan to relatively large development. 因BMC团状模 plastics tool has excellent electrical properties, mechanical properties, heat resistant property, chemical resistant property, also various molding process, can meet/satisfy various product for property can requirements, therefore 越 越受 to large use 户 喜爱.
一, electrical parts low pressure type: RT series, 隔离开关, gas 开关, electrical 盘, electrical table/sheet outer housing/shell and other;
high pressure type: insulation 子, insulation 罩, 消弧罩, 封闭引线 sheet/plate, ZW, ZN true series.
二, automotive parts 车灯发射 device, Japan 车灯反射 device 几乎都 use DMC made formed;
automotive device, separation and decoration sheet/plate, 喇叭箱 and other;
三, electrical machine parts 空调马达, electrical machine 轴, ring framework, electrical and 汽动部 parts.
四, day use product type micro 波炉餐 tool, electrical outer housing/shell and other.
packaging, 运输, 存放
BMC series plastics in composite/compounding film bag in, 每包25公斤, rear 装入纸箱;
运输途 in anti heavy pressure, hot and packaging loss;
贮存期 in temperature degree low 于25?C避 cationic light drying in, production day 算起三 month, ultra- 保存期经复检 combined still can use.
BMC series plastics molding process
模 pressure molding temperature degree: 150?C±5?C injection molding temperature degree: 125?C±5?C holding pressure time: 60-70s/mm pressure pressure: 10-20Mpa specific process product and mold structure 而定, if products thick degree comparison thick, temperature degree low, generally molding temperature degree is 135?C-145?C, 形状越 complex, molding pressure high.

BMC材 material property can  

main/primary tool has below/following excellent property can: appearance excellent 美亮丽, color property 佳, low shrinkage rate, easy deformation, formed product dimensions non stability, high strength, electrical insulation property excellent, resistant property 极佳, tool resistant property, easy 风化.
