【正文】 y when we suit for injection time too long, it may cause a series of defects suck as flash all sorts of factors should be considered, injection time should be shout if quality suit for ,背壓設定的大小,但有一點, time depends on plastic speed and screw back pressure, but plastic time must shorter than cure :冷卻時間的長短直接影響到成型的周期,冷卻時間越長,成型時間就越長,造成產(chǎn)能就越低,故我們在設定高壓冷卻時間時,只要能保證到產(chǎn)品成型順利,不會直接影響到變形等問題, time: Cure time affects molding cure time, longer molding cycle, lower production it sets cure time short on condition that product molding succed and can’t deformation..,我們的頂出時間一般是與機械手配合為宜,半自動生產(chǎn),如因頂針退回會導致產(chǎn)品掉落或卡緊,而取不下產(chǎn)品, PCE pany, for using manipulator in abundence , knocking out time

Setting按成型步驟:可分為開鎖模,加熱,射出, steps: mold opening/closing, heating injection and knocking :Mold opening parameter:快速段中速度低壓高壓速度HighspeedmidspeedLow pressure high pressure speed鎖模條件設定:Mold closing parameter setting1鎖模一般分:快速→中速→低壓→高壓Mold closing: highspeed →lowspeed →low pressure→high pressure,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/,但卻必須遵循一個這樣的規(guī)則,即由射口筒到In highspeed section, Mold closing speed depends on of two –plate mold it can set quick and evenespecially quick usually, it set speed within 5575%.ForThe proper temperature setting differs depending on fullplate mold it set speed within8090% while using type of resin material, but it must be abide by a rule that especially high speed it set speed within 4555% and temperature setting should diminish in step from pressure within 5075% position distance setting differs nozzle to feeding resin material on the volume of product and usually it can be set 1/3 of mold opening ,則射口筒溫度應降低,如,在快速段結束后即轉換成中速,中速的位(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Nozzle temperature setting should low if product %45% resin material such asIn midspeed section: Mold closing speed changes intoPPS, PA, cool very soon , Nozzle temperature should midspeed after highspeed section start higher more than the second cylinder is where two plates meet(include threeplate mold and twoplate mold)Distance of midspeed is up to,一般出于distance of two plates plate it speed within 3050% and 對機臺油路中的油封保護需要,油溫最好能控制在40度pressure 2045%.60度,以免油封長期高壓而變化,縮短使用壽命,造成成型,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,Pump turning on temperature is different depending on 這個數(shù)字一般是以這點為標準，即于此點則起不了高壓,type of
