high temperature resistance ABS injection molding technology
high temperature resistance ABS injection molding technology
ABS resin | technology 文章 | Daoqin plastics raw materials
本文 will detailed introductionacrylonitrile-butadiene-styrene (ABS) copolymer （ABS）material property can features, application areas and processing process, is material selection and product design provide 参考.
detailed introduction
截止 to currently is 止, field/area about/regarding high temperature resistance ABS plastics many also can 进行完 full 清楚明白 进行 understanding 释, ratio its in more separation injection molding, is its in especially 不太容 easy understanding 释 术语之一. generally 说, this type of more separation injection molding technology 里面包括 good multiple injection molding technology. in high temperature resistance ABS plastics 进行组装 and injection molding process in, can production can and can 进行拆卸 separation understanding 连接. generally 说, in production various toys or ratio toys also small parts 时候就不 can 避免 会 use this can 够拆卸 separation understanding 连接, ratio production type table/sheet 时候就 can utilizing this type of technology.
this type of technology process composite/compounding injection molding technology full different, is positive versus 反, process need use various material can versus and, but also also must need tool has viscous property, meanwhile also need tool has 一定程 degree shrinkage property. generally lower, production tool has very more plastics parts need application injection molding technology. this type of injection molding technology requirements material need has table/sheet 皮层, but also also need has in 心层, use this type of methods can very multiple type type and plastics 进行组 combined, this its in 就包括 can recycling again utilizing high temperature resistance ABS材 material.
utilizing formed injection molding method can 进行夹层 injection molding. this is is types material is from 同样 一 gate 出. is this type of technology especially complex, 三言两语 very difficult understanding 释清楚, therefore in this for this type of technology again more add introduction.
[材 material basic parameters ]
| density | 1.04~1.06 g/cm³ |
| 玻璃化转变 temperature degree | 105°C |
| heat deflection temperature (HDT) | 85~110°C |
| tensile strength | 40~55 MPa |
| flexural modulus | 2000~2600 MPa |
| notched impact strength | 200~400 J/m |
| molding shrinkage | 0.4~0.7% |
| 洛氏 hardness | R100~R120 |
core advantages
- 卓越 comprehensive property can: high strength, high toughness, high rigidity 于一体, is " full can type " engineering plastics
- excellent impact resistant property: butadiene versus its tough property, notched impact strength can 达200-400 J/m
- good surface quality: easy obtain high gloss degree surface, combined appearance requirements high products
- excellent processing properties: flow property good, injection molding easy, products surface light
- easy modified: can through blending, reinforcement, flame retardant and other methods obtain various property can
- property ratio high: price in, property can excellent, is most use engineering plastics 之一
application areas
electrical machine outer housing/shell, 空调面 sheet/plate, machine parts, device housing/shell
table/sheet sheet/plate, 格栅, inner trim parts, rear housing/shell 体, direction
electrical outer housing/shell, printing machine parts, electrical machine, electrical appliances housing/shell
high 积木, various toys housing/shell 体, type parts
行李箱, tool 箱, safety anti 护箱
injection molding processing process
- drying 处理: 80~85°C drying 2-4 small 时, moisture content ≤0.1%
- material temperature degree: 200~240°C
- mold temperature degree: 40~80°C
- injection pressure: 60~100 MPa
- injection speed degree: in and other to fast speed
- precautions: ABS products easy generate internal stress, molding rear can 进行退火处理消 remove force
