我们是一家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 Jinan injection processing manufacturer. In the injection molding process, we will encounter the situation of 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 of basic information about injection molding. Now 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 disadvantageous factors will high temperature bring to us in the process of injection molding? It mainly includes five aspects.

一、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 molding process is too high, the viscosity of the oil will decrease and the leakage may increase. 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 oil decreases, the oil film of moving parts such as valve core will become thin or cut off. At this time, the friction resistance will also increase, which will increase the wear phenomenon.
二、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: in the process of injection molding, too high temperature will accelerate oil oxidation deterioration, dissolve asphalt material, reduce the service life of hydraulic oil, and analyze the material will block the damping hole and clearance valve port, resulting in the pressure valve stuck. If it does not work, the metal pipe will stretch and bend, even fracture.
三、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、 Deterioration of working quality of injection molded parts: too high temperature in the injection molding process will lead to deterioration of working quality of injection molded parts, and air in the oil will also dissolve and escape, resulting in cavitation, thus reducing the performance of the hydraulic system.
四、是机器的热变形现象:液压元件的热膨胀系数不同的元件,由于学徒期一定减少,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 coefficient of thermal expansion of the hydraulic components, due to the reduction of apprenticeship period, get stuck, cause work failure, seriously affect the transmission accuracy of the hydraulic system, and cause the decline of the quality of injection molded parts.
五、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 make rubber seal deform, accelerate aging failure, reduce the service life of sealing performance and cause leakage.
