For many plastic processing defects formation mechanism and cleaning methods to carry on the list, after summarizing, refining and summarizing the occurrence of more than 1000 cases of plastic molding processing defects elements and cleaning process and the method has made the analysis and propositions, supply some targeted strong solution and method, for plastic coaming box engineers see when cleaning the defects, it can greatly shorten the process of cleaning the defects of exploration and find countermeasures of in many of the literature.
As for the plastic coaming box engineer, how to adjust the technical parameters and set the molding conditions reasonably, how to correctly adjust the mold and quickly clean all kinds of molding defects is a practical technology that should be mastered.However, because the components of product defects many, the causes of the mechanism is more complex, generally begged the defect cleaning personnel is necessary to have certain theoretical knowledge and rich practical experience, talent correctly analyze the occurrence of defects, determine the appropriate treatment plan, handy cleaning all kinds of plastic processing defects.
It is worth paying attention to, when cleaning defects, it is necessary to adjust the technical parameters, not to change several production conditions.Together, for example, avoid by all means change the molding temperature, molding pressure, or the cavity structure and so on many technical parameters, and plastic coaming box when the defect should be temporarily stable production conditions, first clean the defects of the main causes, then the change of visual defects, and to adjust the other processes, in turn until the defects shall be completely cleared away.
Also need to be careful is that sometimes the same kind of products occur not the same forming defects, there will be the same elements and cleaning method.In this regard, in order to avoid duplication in the list, this article generally lists out the cause mechanism and countermeasures of defects in the previous presented items, and only gives a brief introduction in the later presented items.Therefore, before determining the cleaning plan for a defect, it is best to look at the occurrence of the defect under other molding conditions and the cleaning method, and then determine the general treatment plan.
