compared with the double-head electric heating tube, the single-head electric heating tube is discharged from one end. The single-head heating tube can be either a lead wire or a terminal, and the customer can wire it himself. The single-head electric heating tube is generally used for air-drying or heating the liquid, and the heating liquid can be screwed at the top of the heating tube to prevent movement. Air dry burning mainly refers to the heating of the single-head electric heating tube of the mold, which can be directly inserted into the drilling hole of the mold. It can be a single straight rod, or it can be fixed at the outlet end with a limit piece. According to the customer's demand, choose a reasonable stainless steel electric heating tube design. .
