適當提高機筒溫度,使氣體容易逸出,但PC/ABS塑料的溫度不宜超過270℃,以防高溫分解,影響PC/ABS塑料的性能。
Properly raise the barrel temperature to make the gas easy to escape, but the temperature of pc/abs plastic should not exceed 270 ℃ to prevent high-temperature decomposition and affect the performance of pc/abs plastic.
在注射成型過程中,應(yīng)適當降低注射壓力和注射速度,使氣體有足夠的時間排出。需要注意的是,注射壓力和注射速度是相互關(guān)聯(lián)的,在調(diào)整的時候不能同時改變兩者,因為無法確定產(chǎn)生氣紋的原因是注射壓力過大還是過大。
During the injection molding process, the injection pressure and injection speed shall be properly reduced to allow sufficient time for the gas to be discharged. It should be noted that the injection pressure and the injection speed are interrelated, and the two cannot be changed at the same time during adjustment, because it is impossible to determine whether the cause of gas wrinkles is too high injection pressure or too high injection pressure.
調(diào)整期間的注射速度。正確的方法是先選擇其中一個參數(shù)進行調(diào)整,然后看看它產(chǎn)生的效果,再決定下一步。
Injection speed during adjustment. The correct method is to select one of the parameters to adjust, and then look at its effect before deciding on the next step.
通過增加背壓和提高熔體速度,可以將包裹在原料中的空氣和原料揮發(fā)相產(chǎn)生的氣體從機筒后段充分排出。
By increasing the back pressure and the melt speed, the air wrapped in the raw material and the gas generated by the volatile phase of the raw material can be fully discharged from the rear section of the barrel.
改善模具的排氣。確保在注塑過程中材料充入模具時產(chǎn)生的各種氣體能順利排出模具。
Improve mold exhaust. Ensure that all kinds of gas generated when the material is filled into the mold during the injection process can be discharged smoothly from the mold.
原料應(yīng)充分干燥。建議在70℃~80℃下干燥時間不少于4小時,并采取防潮措施(尤其是雨天),防止水汽的影響。
The raw materials shall be fully dried. It is recommended to dry at 70 ℃ ~ 80 ℃ for at least 4 hours, and take moisture-proof measures (especially in rainy days) to prevent the influence of water vapor.
濟南注塑加工廠家認為要想提高注塑加工的產(chǎn)品的質(zhì)量可以這樣做,比如:制定一套完整的注塑加工塑料模具生產(chǎn)管理系統(tǒng),實現(xiàn)模具在生產(chǎn)管理流程的產(chǎn)品數(shù)據(jù)的管理、工藝數(shù)據(jù)管理、計劃管理、進度管理的計算機信息化管理系統(tǒng),包括模具生產(chǎn)計劃的制定、模具設(shè)計、工藝制定、車間任務(wù)分派和產(chǎn)品檢驗,庫房管理等,使塑料模具在制造及相關(guān)輔助信息從計劃制定到完工交付能夠?qū)崿F(xiàn)跟蹤管理。
Jinan injection molding manufacturers believe that they can do this to improve the quality of injection molding products. For example, they can develop a complete set of injection molding plastic mold production management system to realize the computer information management system of product data management, process data management, plan management and progress management of the mold in the production management process, including the formulation of mold production plan, mold design, process formulation Workshop task assignment, product inspection, warehouse management, etc. enable all-round tracking management of plastic mold manufacturing and related auxiliary information from plan formulation to completion and delivery.
將計劃、設(shè)計、加工工藝、車間生產(chǎn)情況、人力資源等的信息有機地組織、整合在一起進行統(tǒng)籌,從而有效協(xié)調(diào)計劃和生產(chǎn),能夠有效保證塑料模具質(zhì)量并如期交貨。
Organically organize and integrate the information of planning, design, processing technology, workshop production, human resources, etc., so as to effectively coordinate planning and production, effectively ensure the quality of plastic molds and deliver them on time.
