【正文】 mperature is different depending on type of injection molding machine. To protect oil seal of machine it set oil temperature within , If oil seal work on condition that high pressure and damaged It’s work time will be shorter, it can cause molding stable.第三節(jié)注射及熔膠(加料)工藝條件設(shè)定 ,則射口筒溫度應(yīng)降低,. 加熱工藝條件設(shè)定 ,低速設(shè)定一般是在模板接觸的一瞬間,具體位置就設(shè)在機(jī)臺(tái)顯示屏顯示的一瞬間的數(shù)字為準(zhǔn),這個(gè)數(shù)字一般是以這點(diǎn)為標(biāo)準(zhǔn),即于此點(diǎn)則起不了高壓,高于此點(diǎn)則大,%25%,視乎不同機(jī)種而定,壓力一般設(shè)定于12%,有些機(jī)則可設(shè)于515%,也是視乎不同機(jī)種不同. ,如果是平面二板模具,快速鎖模段可用較快速度,甚至于用到特快,當(dāng)用到一般快速時(shí),速度設(shè)到5575%,完全平面?？稍O(shè)定到8090%,如果用到特快就只能設(shè)定在4555%,壓力則可設(shè)定于5075%,位置段視產(chǎn)品的深淺(或長短)不同,一般是開模寬度的1/3. Mold closing: highspeed →lowspeed →low pressure→high pressure Mold closing parameter setting Low pressure high pressure speed 低壓高壓速度 Mold opening parameter: Molding steps: mold opening/closing, heating injection and knocking out. Section 2 Molding parameter Setting 成型工藝參數(shù)的設(shè)定須根據(jù)產(chǎn)品的不同設(shè)置. . (2)合模參數(shù) (1).注塑參數(shù) 第一節(jié) 成型工藝成型工藝流程及條件介紹(注塑技術(shù)英語大全)成型工藝流程及條件介紹 In midspeed section: Mold closing speed changes into midspeed after highspeed section finish. Midspeed start position is where two plates meet (include threeplate mold and twoplate mold ) Distance of midspeed is up to distance of two plates plate it speed within 3050% and pressure 2045%. Highpressure section: To normal injection molding machine, highpressure position had been set before they were sent to customer. It can not be modified. For example highpressure position of CHENHSONG machine is speed of highpressure section is about 3035% and higher than that of lowpressure. The pressure is up to mold, it can set within 5585% For fullplate mold, it’s eject air well, it can set pressure 55% .If mold has a lot of slides and flash rate high in production, pressure can set 90%. The proper temperature setting differs depending on type of resin material, but it must be abide by a rule that temperature setting should diminish in step from nozzle to feeding resin material position. ,一般出于對(duì)機(jī)臺(tái)油路中的油封保護(hù)需要,油溫最好能控制在40度60度,以免油封長期高壓而變化,縮短使用壽命,造成成型不穩(wěn)定. Injection Name熔點(diǎn)℃ Mold Temperature(‘c)干燥溫度℃ ,當(dāng)然也可以依據(jù)公式來計(jì)算,如公式: Si:注射行程。 Ds:螺桿直徑。 0. 785: value ofΩ/4. Step 2 inject 2/3 of product. It can lower 2/3 of product according to requirement of p
