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.
