Shanghai Daoqin Plastics Co., Ltd.

plastics products in production active in already can separation, this type of supply and demand 关系也推动 injection molding parts 业 迅猛 development. future dilute has property, control cost is 商家必争课题. due to injection molding parts products by industry using/adopting, for parts density requirements formed inner difficult 题. nitrogen gas injection shot as is high new technology, in also to 广泛认知. lower heavy introduction lower nitrogen gas injection shot excellent property. injection shot is will solvent melt plastics through machine can high pressure injection to mold cavity inner molding.但 in injection, holding pressure, cooling, shrinkage process in generate force, and parts thick shrinkage 不一, make parts deformation 曲翘, therefore effect/influence parts degree. nitrogen gas injection shot nitrogen gas holding pressure, it is will nitrogen gas high pressure shrink (high most can 达350bar)引入 mold cavity (塑 parts) internal, 接替传统 injection shot holding pressure.明确点说就 is injection molding parts machine need formed injection mold cavity 需75%-95% 计 amount,余 lower holding pressure nitrogen gas formed. due to nitrogen gas in parts internal formed in nitrogen gas high pressure bubbles,并 through gas features uniform will pressure toward outer expand 张, therefore it force is 不变.记住 bubbles 永远都 会 in in 部, meanwhile according to parts 形状自动充满壁 thick relatively thick 位置.经 cooling rear in mold opening front gas pressure, this 样 结果, holding pressure force 平均(没 has injection force), shrinkage force 平均.由此 to parts stability high degree dimensions. upper 述 动 as meanwhile can to more more 帮助:1. in large degree reduce force lower,塑 parts dimensions to ensure 障;2. due to need injection 75-95% 计 amount, therefore,塑 parts weight decrease light, according to parts outer 形而定, can to 节省35% or above raw materials;3. 我们说, in parts internal formed in 空, through function,塑 parts structure to add strong/high;4. due to it is high pressure formed 形, appearance upper sink marks 痕迹也 obvious 不见;5.肉 thick in 空, cooling time decrease/reduce 约35%, formed cycle 也随之改变;6,因 is gas 体形状 随意 property, product design made decrease/reduce,不 again 期望抽芯 or molding processing;7 nitrogen gas is in parts internal formed pressure. therefore pressure reduce. need injection molding parts mold dimensions 允许,您 can in relatively small machine upper production,由此 reduce equipment loss consumption. above technology by widely used in automotive,音响, electrical 视, electrical 脑, printing machine, furniture,餐 tool,保健 device 材,箱包 and other industry,国际国 inner injection molding parts processing already using/adopting 并获认 can,知名 如SONY, Chi Mei, light electrical,京瓷,三星;海尔,奂鑫,华博,荣 formed and other. has is degree, has is material,都 has for advantages!
