1. A food heating mat manufacturing process, comprising the following steps:
Step 1: manufacturing silicone layers by cutting the silicon layers into a predetermined size;
Step 2: treating a heating film by cleaning a surface of the heating film, uniformly coating the surface of the heating film with a treating agent, and then baking the heating film coated with the treating agent;
Step 3: combining the silicone layers and the heating film to form a mat body by bonding the heating film in between two silicone layers;
Step 4: placing the mat body into an inner cavity of a die, and molding the mat body at a temperature of at least 110° C. and a pressure of at least 180 KPa;
Step 5: assembling a food heating mat, placing a temperature control probe in the mat, and installing a controller; and then
Step 6: testing the food heating mat.
