Packaging Industry
Packaging Industry
Application of plastic welding technology in packaging industry:
According to experiments, most traditional methods of sealing thermoplastic packaging can be replaced by ultrasonic welding. With more than 10 years of experience in the field of ultrasonic welding, Hengda provides customers in the packaging industry with solutions including ultrasonic, vibration and friction and other welding methods.
Advantages of ultrasound to the packaging industry:
-Greatly shorten the processing time, the combination of plastics can be completed in a few milliseconds
-Application of ultrasonic for processing, the process is clean, stable and reliable, and low energy consumption
-Ultrasonic energy is only consumed in the precise area where welding is required, which is efficient and economical
-No need to preheat and keep warm during operation; use of ultrasonic will not generate excess heat
-There is no need to use expensive and easily polluted auxiliary products, such as adhesives, buttons or adhesives; the processed packaging is environmentally friendly and renewable
-Seal welding can be carried out through dirt (such as liquid, grease, powder, etc.) without affecting the welding effect
-Ultrasonic equipment and its components are easy to use in automated production environments and are compatible with material conveying systems
-The control unit based on microprocessor technology or customized by the customer can accurately set the equipment, and can be adjusted quickly through parameter storage and memory function; advanced control and alarm system ensure the optimization of operation and output
Note: E = excellent, G = good, F = fair, P = not good, - = means that the process and materials do not match
