First, to see the feasibility of the scheme, the scheme of a stove is just like a child's inherent constitution. The merits and demerits of the scheme determine the performance of the stove. At present, the proposed scheme is that the half-bridge scheme is still acceptable, but the whole bridge must be used to solve the stability problem. The author has discussed the stability of the large stove with many commercial electromagnetic stove manufacturers. As a result, manufacturers using the half-bridge scheme have indicated that they are still at a loss to control the quality stability.

Second, whether the product inspection process is in place. Many manufacturers of electromagnetic ovens have assembled the machines from beginning to end, and then ready to deliver them in 10 minutes. This is very imprecise. Every oven will have some controllable problems more or less. Therefore, the detection of each process becomes indispensable. It must not be a simple 10-minute power-on to ship, which is bound to happen. It will bring customers a lot of after-sales use, according to the usual, every commercial electric furnace at least have problems found in the factory.

Third, look at the regularization of production. Regularized production is mainly reflected in the comprehensive quality of workers, for example, responsible workers, take great care to do every detail, because they know that if there is a place not to grasp, it will become a future after-sales problem, and as a manufacturer, after-sales cost has become an additional cost that can not be ignored, as well as for customers. The stability of product quality also directly affects the efficiency of work.
