Causes of defects in injection mold machine for plastic chair and their treatment methods

Possible defects

In the process of plastic chair processing, it may be due to poor raw material handling, unreasonable product or mold design, operators not mastering the appropriate process and operating conditions. Or due to inappropriate machine, it often result products with unqualified, depression, flashing, and air bubbles, cracks, warpage deformation, dimensional changes and other defects.

There are three main aspects in the evaluation of plastic chairs. The first is the appearance quality, including completeness, color, gloss, etc.; the second is the accuracy between the size and relative position; the third is the mechanical properties, chemical properties, and electrical performance, etc. These quality requirements are based on the different occasions where the plastic chair is used, and the required scales are also different.

Production practice has proved that the defects of plastic chairs mainly lie in the design, manufacturing accuracy and degree of wear of the mold. But in fact, the technicians of plastic processing plants often suffer from the difficult situation of using technological means to compensate for the problems caused by mold defects without great results.

Approach

The adjustment of the process in the production process is a necessary way to improve the quality and output of products. Because the injection cycle itself is very short, if the process conditions are not well mastered, there will be an endless stream of waste products. When adjusting the process, it is best to change only one condition at a time, and observe more opportunities. If the pressure, temperature, and time are all adjusted together, it is easy to cause confusion and misunderstanding. Apart from the problem, it is not known what the cause is.

The measures adopted when adjusting the process are multifaceted. For example, there are more than 10 possible solutions to solve the problem of product dissatisfaction, and the main solution must be selected to deal with the problem. In addition, we should also pay attention to the dialectical relationship in the solution. For example, if the product has a depression, sometimes the material temperature must be increased, sometimes the material temperature must be lowered; sometimes the material quantity must be increased, and sometimes the material quantity must be reduced. It is necessary to recognize the feasibility of reversing measures to solve the problem.
