Materials may scatter, causing waste of raw materials. Secondly, some devices are unable to make materials more compact through vibration, affecting product strength. The lack of vibration may lead to bubbles inside the finished product. The material cannot be further mixed through vibration, which may lead to uneven performance of the finished product. The lack of automated vibration may require manual operation, reducing production efficiency. Finally, the upper and lower molds of some devices may not be accurately aligned, affecting the accuracy of the finished product. The lack of guidance may lead to uneven pressure distribution, affecting the quality of the finished product. The lack of an automated molding mechanism may increase operational risks.
