济南注塑加工过程中高温带来什么影响?

我们是一家靠谱的济南注塑加工制造商。在注塑过程中,我们会遇到温度过高的情况。面对这种情况我们需要做什么?高温给我们带来什么不便?
We are a reliable injection molding manufacturer in Jinan. In the process of injection molding, we will encounter too high temperature. What do we need to do in the face of this situation? What inconvenience does high temperature bring us?
我们已经介绍了很多关于注塑成型的基本情况。下面我们将直接介绍与温度有关的情况。
We have introduced a lot about injection molding. Below we will introduce the situation related to temperature directly.
注射成型过程中高温会给我们带来哪些不利因素?主要包括五个方面。
What are the disadvantages of high temperature in injection molding? It mainly includes five aspects.
1、温度过高会降低机油的粘度:当注塑工艺过高时,机油的粘度会降低,而且可能会增加泄漏。此时,泵的容积效率和整个系统的效率也会明显降低。如果油的粘度降低,阀芯等运动部件的油膜会变薄或有被割断的现象。此时,摩擦阻力也会增加,这会增加磨损现象。

1. Too high temperature will reduce the viscosity of the oil: when the injection process is too high, the viscosity of the oil will be reduced, and the leakage may be increased. At this time, the volumetric efficiency of the pump and the efficiency of the whole system will also be significantly reduced. If the viscosity of the oil decreases, the oil film of the moving parts such as the valve core will become thin or cut off. At this time, the friction resistance will also increase, which will increase the wear phenomenon.
2、加速油氧化变质:注塑过程中温度过高会加速油氧化变质,溶解沥青物质,降低液压油的使用寿命,分析物质会堵塞阻尼孔和间隙式阀口,导致压力阀卡死如果不工作,金属管就会拉伸弯曲,甚至断裂。
2. Accelerated oil oxidation deterioration: too high temperature during injection molding will accelerate oil oxidation and deterioration, dissolve asphalt materials, reduce the service life of hydraulic oil, analyze materials will block the damping hole and clearance valve port, resulting in the pressure valve stuck. If not working, the metal pipe will stretch and bend, or even break.
3、,注塑件的工作质量恶化:注塑过程温度过高,会导致注塑件的工作质量恶化,油中的空气也会溶解逸出,产生气穴,从而降低了液压系统的性能。
3. The working quality of the injection molding parts deteriorates: if the injection temperature is too high, the working quality of the injection molded parts will deteriorate, and the air in the oil will also dissolve and escape, resulting in cavitation, which will reduce the performance of the hydraulic system.
4、是机器的热变形现象:液压元件的热膨胀系数不同的元件,由于学徒期必须减少,卡死,造成工作故障,严重影响液压系统的传动精度,并造成注塑加工件的质量下降。
4. It is the thermal deformation phenomenon of the machine: the components with different thermal expansion coefficients of hydraulic components have to be reduced in apprenticeship and stuck, resulting in work failure, seriously affecting the transmission accuracy of the hydraulic system, and causing the quality of injection molding parts to decline.
5、是会使橡胶密封变形,加速老化失效,降低密封性能的使用寿命,造成泄漏。
5. It will cause rubber seal deformation, accelerate aging failure, reduce the service life of sealing performance and cause leakage.
以上就是济南注塑加工厂家给大家的分享。
