Application of ultrasonic welding in plastics industry

 Ultrasonic plastic welding machine is mainly used for the secondary connection of thermoplastics, compared with other traditional processes (such as adhesive, electric pressing or screw fastening, etc.), with high consumption efficiency, good welding quality, environmental protection and energy saving and other significant advantages. Ultrasonic plastic welding equipment is widely used in medical equipment, packaging, auto parts, fishing gear and other industries, such as automobiles, clothing, plastic toy zipper bag, plastic wine bottle cap, dishwasher water wheel, plastic false bait, charger shell and mobile phone sling welding, a lighter shell welding and so on.

Ultrasonic welding principle:

By ultrasonic vibration, the electronic energy is converted into mechanical energy, and then the energy is transmitted to the contact surface of the plastic bow and arrow by the welding head (HORN), which causes intense friction between molecules and heat generation principle, and promotes the product to condenze and separate into one, and the processing speed is fast, clean, beautiful and economic.

Welding scope: toy industry, stationery industry, home appliance industry, electronics industry, food industry, communication industry, transportation industry, etc.

Ultrasonic welding examples:

Daily necessities industry: powder case, makeup mirror, hair comb, lock ring, thermos cup, sealed container, seasoning bottle, water pipe joint, lift, bottle cap, food container... Let's wait.

Toy industry: all kinds of ball toys, stationery, water guns, plastic gifts, music toys, and all kinds of plastic toys... Let's wait.

Electrical industry: electronic clock, steam iron, vacuum cleaner, telephone, computer keyboard, electric fan, battery... Let's wait.

Automotive manufacturing: direction lights, rear mirrors, all kinds of plastic waste... Let's wait.

Rotating welding principle:

The system is designed for the thermal plasticity of plastic circular products, through the heat generated by the friction of the plastic workpiece, the contact surface of the plastic workpiece is melted, and then by the external pressure, the upper and lower parts are driven to solidify as a whole, becoming a permanent separation.

Rotational melting examples: RO filter core, frozen cup, thermos cup, vase, carburetor, showerhead, hot water bottle gas bladder, where and street number.

Hot plate welding principle:

The application template is heated to the required temperature, and then placed in the middle of the separation surface of the plastic workpiece and the workpiece, so that the heat is concentrated in the two separation surfaces, when the heat is generated by melting, after exiting the hot template, the external pressure is applied, resulting in the workpiece being one and becoming the function of consolidating durability. It can handle the welding material, its own hardness is high, complex shape, and large products can be met and solved.
