In this paper,we introduced main factors affecting the temperature control mechanism of mechanical oven including the temperature control accuracy of the liquid expansion thermostat,the position of the temperature probe,the power of the heating pipe,the weight,thickness of the insulation cotton and also the way we wrap the insulation cotton,and the accuracy of the silk-screen.Thus,in order to improve the temperature control accuracy of mechanical ovens,we recommend that the key parameters throughout the process of oven manufacturing production should be controlled prop-erly.
