Causes and solutions of folding in injection molding

When we encounter wrinkles during injection molding, we may feel confused and helpless. However, the causes and solutions of wrinkles are not difficult to understand, as long as we have some basic knowledge, we can easily solve the problem.

Let's take a look at the causes of wrinkles in injection molding. This is usually caused by incorrect process parameters such as material temperature, mold temperature or injection pressure. In addition, poor material quality or poor design can also cause folding problems. So, how to solve the problem of folding in injection molding? In fact, the solution is very simple, just follow the following steps to do it.

The first step is to adjust the process parameters such as material temperature, mold temperature and injection pressure. Specifically, we can improve the fluidity of the material by increasing its temperature to better fill the mold. At the same time, we can also adjust the mold temperature and injection pressure to ensure that the material can fill the mold evenly and avoid wrinkles.

Second, check the quality of the material. If the material quality is not good, then even if the process parameters are adjusted correctly, there will still be folding problems. Therefore, we need to choose high-quality materials and carefully inspect and test them before use.

The third step is to examine the product design. Sometimes, folding problems in injection molding are caused by poor product design. For example, problems such as thin walls and acute angles in product design can easily lead to folds. Therefore, we need to review and optimize the product design to eliminate these issues.

Through the above three steps, we can effectively solve the folding problem in injection molding. Of course, in actual production, we also need to pay attention to some details, such as maintaining the cleanliness of the mold, avoiding overfilling and so on.

The folding problem in injection molding is not terrible, as long as we have the right solution, we can easily solve this problem. At the same time, we also need to accumulate experience in the production process, and constantly improve the production process and quality control system to ensure the quality stability and production efficiency of injection molding.
