,則射口筒溫度應降低,. ,但卻必須遵循一個這樣的規(guī)則,. 加熱工藝條件設定 ,按一般機臺而言,高壓位置機臺在出廠時都已作了設定,相對來講,是不可以隨便更改的,大約在3035%左右,而壓力則視乎模具而定,可在5585%中取,比如完全平面之新模,模具排氣良好,甚至于設在55%即可,如果是滑塊較多,原來生產(chǎn)時毛邊也較多,甚至于可設在90%還略顯不足. ,低速設定一般是在模板接觸的一瞬間,具體位置就設在機臺顯示屏顯示的一瞬間的數(shù)字為準,這個數(shù)字一般是以這點為標準,即于此點則起不了高壓,高于此點則大,%25%,視乎不同機種而定,壓力一般設定于12%,有些機則可設于515%,也是視乎不同機種不同. ,在快速段結(jié)束后即轉(zhuǎn)換成中速,中速的位置一般是到模板(包括三板模,二板模)合在一塊為止,具體長度應視模板板間隔,速度一般設置在30%50%間,壓力則是20%45%間. ,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,當用到一般快速時,速度設到5575%,完全平面??稍O定到8090%,如果用到特快就只能設定在4555%,壓力則可設定于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 1鎖模一般分:快速→中速→低壓→高壓 Mold closing parameter setting 鎖模條件設定: Low pressure high pressure speed Highspeedmidspeed 低壓高壓速度 快速段中速度 Mold opening parameter: 開鎖模條件: Molding steps: mold opening/closing, heating injection and knocking out. 按成型步驟:可分為開鎖模,加熱,射出,頂出四個過程. Section 2 Molding parameter Setting Molding technique parameter setting differs depending on type of product 第二節(jié)成型條件設定 成型工藝參數(shù)的設定須根據(jù)產(chǎn)品的不同設置.

Section 1 molding technique. 第一節(jié) 成型工藝 Molding technique procedure and parameter introduction成型工藝流程及條件介紹(注塑技術英語大全)成型工藝流程及條件介紹 In highspeed section, Mold closing speed depends on type of mold. For two –plate mold it can set quick and even especially quick usually, it set speed within 5575%. For fullplate mold it set speed within8090% while using especially high speed it set speed within 4555% and pressure within 5075% position
