The cutting process of fabrics is generally divided into cold cutting and thermal cutting, both of which have certain limitations. Compared to cold cutting, the edges of the cut edge are fused after the thermoplastic material has been cut using ultrasonic fabric cutting; Compared with the thermal cutting process, the use of ultrasonic cutting can make the edge of the fabric being cut very soft and avoid excessive edge thickening due to melt shrinkage. Since the ultrasonic waves are heated from the inside of the fabric, there is no fabric yellowing. Since the ultrasonic waves are heated from the inside of the material, there is no fabric yellowing.
For rubber products, cold cutting is more suitable than thermal cutting. Cold cutting has the advantages of generating less heat, less thermal deformation, less dust generated during the cutting process, and the section will not be aged and cracked due to high temperature. Ultrasonic rubber cutting technology belongs to cold cutting, which uses ultrasonic energy, the rubber to be cut locally heated melting, to achieve the purpose of cutting the material. It can solve low productivity and personal safety in traditional rubber cutting.
