What should I do if the electric toothbrush is warped and deformed during injection molding
? Warpage and deformation often occur during the manufacturing process of injection molds. Similar problems will inevitably occur in the two-color injection molding of electric toothbrushes. So, what is the reason for the deformation and how to solve it? Shanghai Mulan Injection Molding Factory said that there are many reasons for the warping deformation of the electric toothbrush, which may be caused by the uneven wall thickness of the injection molded parts during the injection molding process. Deformation may also be caused by uneven shrinkage distribution caused by mold temperature, pressure, and orientation effects. For these reasons, there are mainly the following four solutions:
1. It is possible to change the structure of the electric toothbrush, add ribs, and change the wall thickness;
2. In terms of mold design, it is recommended to redesign the shrinkage rate according to the characteristics of raw materials for electric toothbrush injection molding; increase the design of cooling water channels for injection molds;
3. In terms of injection molding process, it is possible to increase the holding pressure, prolong the holding time, and prolong the cooling time;
How to deal with the warping and deformation of electric toothbrush during injection molding In general, there are many reasons that affect the warping and deformation of electric toothbrush during injection molding, not only the mold structure, but also the injection molding material and the molding and injection molding process parameters etc. When warping occurs, it is necessary to comprehensively evaluate and gradually eliminate the occurrence of the problem, so that the problem can be solved in time.
