本文 will detailed introductionengineering plasticsmaterial property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
engineering use plastics large 家都知道, 也许你 can can it has several types type, has what property can, is do you know it by application in what field/area 吗? small 编 看一 lower 吧.
use engineering plastics more field/area - automotive manufacturing field/area. 现代人 for can 源越 越知道节约. in 出行方面, use more automotive is consumption can relatively high 东西. that is improve/increase automotive safety property and decrease/reduce automotive can consumption amount, 人们就不遗余 force development more add 专业 材 material, to this 目. through outer large type company R&D, automotive field/area is engineering plastics. has engineering use plastics tool has good machine can force and hot can force, therefore in comparison important has application, has tool has very good flame retardant property can, therefore by use in automotive inner product upper 面. 当然随 automotive industrial development, also has more 专业 材 material and use in 里面. that can has metal engineering use plastics 出现, can let automotive more add light 盈, safety, but also can 源.
use engineering use plastics more field/area - electrical appliances manufacturing. large 家都知道, use electrical appliances very more is plastics manufacturing. plastics in electrical appliances as has method ratio advantages. is 我们既 need use to material insulation can force, also need use to versus mechanical properties, has also need use to it resistant hot can force. generally metal material is conductive, use non 常 危险, 而木质 has good property. therefore has use engineering plastics. can 说, has electrical appliances, tube/pipe is use, also is small type also is large type, has engineering use plastics 身影!
core advantages
- excellent force property can: strong/high degree, rigid property and tough property excellent general purpose plastics
- high temperature resistance property: heat deflection temperature (HDT) usually ultra- 100°C, separation can 达300°C above
- good chemical resistance: for multiple chemical product, type and solvent agent has excellent 良 抵 resistant can force
- good dimensional stability: water absorption low, thermal expansion coefficient small
- can substitute/replace metal: in automotive, electronics and other field/area achieve light amount
- design degree high: can through injection molding manufacturing complex parts
application areas
发动 machine parts, system, electrical system, inner trim parts
connectors, 开关, outer housing/shell, insulation parts
gears, bearings, 泵体, 阀门, seals
手术 device 械, diagnosis equipment, device tool
structural parts, inner trim parts, machine parts
injection molding processing process
- according to specific material selection combined drying temperature degree and time
- material temperature degree according to material melting point and heat stabilized property 确定
- mold temperature degree effect/influence crystallization degree and products property can
- injection pressure and speed degree need according to products structure adjustment
- attention/notes material wet property and heat stabilized property
- molding rear necessary rear 处理（退火, wet and other ）
