Shanghai Daoqin Plastics Co., Ltd.

electronics electrical appliances product day small type and more make injection molding parts production need 常常面 for complex, precision, thin plastics products processing difficult 题, this for injection molding parts technology 提出 挑战. as is full injection molding parts processing field/area in technology 先驱, Netstal company is thin made parts production provide solutions. 　　　　 in recent years, electronics electrical appliances product use function day 益趋同化, is, manufacturing 商们开始 will attention/notes force toward product appearance design, utilizing various type product meet/satisfy 消费者 property demand, expand large product market 份额. in addition, for/regarding machine this category of 便携式通讯 equipment 而言, is make 消费者 in use in more add 便利, its outer type structure by design more add small 巧. meanwhile, is ensure battery use internal 空间, must in design upper decrease/reduce this category of product outer housing/shell thick. is, thin 壁, precision injection molding parts made parts in electronics electrical appliances industry in to a large amount of application. 　　 this type thin 壁, precision injection molding parts made parts thick small 于1㎜, various parts, IT made parts, PMMA?DVD machine liquid sheet/plate, PC手 machine and other. this category of made parts outer structure complex, for surface degree requirements very high, therefore for injection molding parts technology non high requirements. 　　 is meet/satisfy this requirements, injection molding parts machine manufacturing in research, development new injection molding parts technology and injection molding parts process. currently, tube/pipe large separation supply in thin product injection molding parts technology already 经积累 very more experience, very less has can provide more good solutions. this is is made parts thick decrease small, requirements injection molding parts pressure more high, speed degree more fast, cooling time more short, meanwhile requirements injection molding parts machine can more add stability 运行. is ensure made parts quality, also requirements more combined gate methods and made parts ejection machine 构. 　　针 for thin made parts processing difficult 题, Netstal development series high compression molding mono 元. as is Netstal machine standards 配置, this mono tool has high injection molding parts pressure, usually can to 3000 bar（1bar=100KPa）, injection speed degree can to 1000 mm/s, can production surface degree high multiple thin products. more is important is, and injection molding parts as 同步进行 high pressure mono and liquid pressure can system can make Netstal injection molding parts machine molding cycle 变 极 short (in injection molding parts production in multiple injection molding parts as 同步进行 and Netstal injection molding parts machine standards liquid pressure can system and high pressure mono make injection molding parts production molding cycle 变 极 short), other machine versus ratio, molding cycle can shrink short 15%～50％, this for thin made parts production non important. need is, can device is Netstal machine standards 配置之一, it is machine in production in obtain stability injection molding parts pressure and speed degree provide ensure. 　　 usually, high pressure injection molding parts molding thin made parts less need 5～7t/in2（投影面积, 1in2=6.45cm2） clamping force, easy make machine in high speed, high pressure production 时发生 bending deformation. is 此, Netstal using/adopting dimensions more large 镀镍模 sheet/plate, ensure machine tool has rigid property. in injection molding parts machine soft parts 方面, Netstal provide most is solutions. Netstal full ring control system can control already to 80点, can through setting parameters 偏差极限, for injection molding parts process in 每一 动 as 进行适时监控并 will 信息适时反馈. Netstal machine in liquid pressure control system is its high 效, system as 时, 油泵会 according to machine to control 信号工 as, for 实际输出 情况进行 in 线实时 testing, this make liquid pressure system in as 时避免 不 necessary can amount 浪费. 　　 need is, Netstal injection molding parts machine in high pressure injection molding parts separation has types screw can selection, standards screw, low pressure injection molding parts screw, HiMelt screw, therefore can suitable for different material, especially combined processing that add 25%～30 % glass fiber reinforcement plastics material, 如LCP, PBT, PPA, PA6, PPS, PA 66, PPO, PC, PEI and other, its in PPA, PPS, PPO, PEI and other material melt temperature degree very high, property very strong/high, for screw abrasion loss non large, resistant 驰特Hi-Melt screw positive is is production this material 而准备. injection molding parts mold is thin made parts injection molding parts formed key/critical factors 之一. usually, is anti gate solid, must high pressure will melt thermoplastic property material fast speed mold cavity in. made parts thick thin, need injection molding parts pressure high, molding cycle short. 例如, if standards made parts in 2s inner formed 充模, that its thick degree will decrease thin 25％. upper causes, Netstal建议 selection injection molding parts mold must tool has good rigid property, ensure in high speed injection 时不发生 deformation. meanwhile, also using/adopting hot runner system, can can decrease/reduce injection molding parts process pressure loss 失. 当然, in injection molding parts mold in using/adopting true system non necessary, has in high speed injection molding parts process in achieve good gas 　　客户 remove can selection Netstal high pressure injection molding parts mono outer, can selection use Netstal standards injection molding parts mono 元, this can make very utilizing 同一台 machine production other plastics products. production product weight increase 时, need more more large screw. usually, more screw and debugging machine can in short time inner formed.
