Quality is the most concerned thing for users to buy Hand panels. The quality of prototype will directly affect the quality, output, cost and the cycle of new products being put into use. In order to solve the problem of the quality of the prototype, it is necessary to strictly control a few aspects. Internal management intensity is very important. An enterprise should have a perfect quality control system, and the experience of the supervisor is very rich. The database is set up, and the optimization is constantly summed up. With the help of the CAE analysis software system, the optimal solution is obtained. Standardizing the production process. The product designer must consider whether the technology and structure of the product accord with the craft and feasibility of the hand plate model making. In the process of making the process, through the analysis of the opponent board, we foresee the defects that the product may produce in the manufacture, thus making a quality manufacturing process plan. The customer needs to meet the quality requirements of the customer's product, and the user also takes into account the cost of material purchase, the design cycle and the strength of the material. As long as these points are well done, it is not a problem to produce high quality prototype.
