Problems solved by technology

For manual and electric control vacuum injection molding equipment, the detection of the vacuum degree is based on subjective judgment by human visual inspection, which is easy to cause problems such as low production efficiency and misoperation, and the influence of human factors is not conducive to the stable control of product quality.
In short, the existing vacuum injection molding control system is highly dependent on the operator's experience and proficiency, and the production efficiency is low and the production flexibility is poor, which makes it difficult to guarantee the quality of the product
