The machine uses a high-precision electronic temperature controller for temperature control, which can be adjusted freely from room temperature to 300 ℃, and can accurately control the shrinkage temperature according to the differences in materials. It adopts imported high-power tubes for stepless speed regulation and automatic voltage stabilization to ensure smooth conveying speed The advantages of one-time and rapid completion of packaging procedures such as film heating, body fitting, air extraction, sealing, and high finished product qualification rate. After packaging with shrink film such as PVC and POF, the product is transparent, aesthetically pleasing, and can achieve dust-proof, moisture-proof, and rust proof effects.
