我們是一家濟南注塑加工制造商。在注塑過程中,我們會遇到溫度過高的情況。面對這種情況我們需要做什么?高溫給我們帶來什么不便?
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?
我們已經介紹了很多關于注塑成型的基本情況。下面我們將直接介紹與溫度有關的情況。
We have introduced a lot of basic information about injection molding. Now we will introduce the situation related to temperature directly.
注射成型過程中高溫會給我們帶來哪些不利因素?主要包括五個方面。
What disadvantageous factors will high temperature bring to us in the process of injection molding? It mainly includes five aspects.

一、溫度過高會降低機油的粘度:當注塑工藝過高時,機油的粘度會降低,而且可能會增加泄漏。此時,泵的容積效率和整個系統的效率也會明顯降低。如果油的粘度降低,閥芯等運動部件的油膜會變薄或有被割斷的現象。此時,摩擦阻力也會增加,這會增加磨損現象。
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、加速油氧化變質:注塑過程中溫度過高會加速油氧化變質,溶解瀝青物質,降低液壓油的使用壽命,分析物質會堵塞阻尼孔和間隙式閥口,導致壓力閥卡死如果不工作,金屬管就會拉伸彎曲,甚至斷裂。
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、注塑件的工作質量惡化:注塑過程溫度過高,會導致注塑件的工作質量惡化,油中的空氣也會溶解逸出,產生氣 穴,從而降低了液壓系統的性能。
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、是機器的熱變形現象:液壓元件的熱膨脹系數不同的元件,由于學徒期一定減少,卡死,造成工作故障,嚴重影響液壓系統的傳動精度,并造成注塑加工件的質量下降。
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、是會使橡膠密封變形,加速老化失效,降低密封性能的使用壽命,造成泄漏。
5、 It will make rubber seal deform, accelerate aging failure, reduce the service life of sealing performance and cause leakage.
