Application of plastic welding technology in packaging industry

According to the experimental results, most of the traditional methods of sealing the thermal plastic packaging can be replaced by ultrasonic welding. With its 30 years of experience in the field of ultrasonic welding, the crown is a solution for the customers in the packaging industry including ultrasonic, vibration and friction.

Advantages of ultrasonic wave to packaging industry: - greatly shorten the processing time, the combination of the plastic can be completed within a few milliseconds - Application of ultrasonic processing, the process is clean, stable and reliable, and energy consumption is low - ultrasonic energy is consumed only in the exact region of the need to be welded, efficient and economical. There is no need to warm up and heat preservation in the operation process; using ultrasonic does not produce excess heat - can be carried out through the dirt (such as liquid, grease, powder, etc.) to seal the welding without affecting the welding effect. - control unit that is based on microprocessor technology or customer customization can be set accurately, and can be adjusted through parameter storage and memory function quickly; advanced control and alarm system to ensure the operation and optimization of the output
