适当提高机筒温度,使气体容易逸出,但PC/ABS塑料的温度不宜超过270℃,以防高温分解,影响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.
在注射成型过程中,应适当降低注射压力和注射速度,使气体有足够的时间排出。需要注意的是,注射压力和注射速度是相互关联的,在调整的时候不能同时改变两者,因为无法确定产生气纹的原因是注射压力过大还是过大。
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.
调整期间的注射速度。正确的方法是先选择其中一个参数进行调整,然后看看它产生的效果,再决定下一步。
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.
通过增加背压和提高熔体速度,可以将包裹在原料中的空气和原料挥发相产生的气体从机筒后段充分排出。
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.
改善模具的排气。确保在注塑过程中材料充入模具时产生的各种气体能顺利排出模具。
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.
原料应充分干燥。建议在70℃~80℃下干燥时间不少于4小时,并采取防潮措施(尤其是雨天),防止水汽的影响。
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.
济南注塑加工厂家认为要想提高注塑加工的产品的质量可以这样做,比如:制定一套完整的注塑加工塑料模具生产管理系统,实现模具在生产管理流程的产品数据的管理、工艺数据管理、计划管理、进度管理的计算机信息化管理系统,包括模具生产计划的制定、模具设计、工艺制定、车间任务分派和产品检验,库房管理等,使塑料模具在制造及相关辅助信息从计划制定到完工交付能够实现全方位跟踪管理。
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.
将计划、设计、加工工艺、车间生产情况、人力资源等的信息有机地组织、整合在一起进行统筹,从而有效协调计划和生产,能够有效保证塑料模具质量并如期交货。
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.
