Car door panel welding machine

Ultrasonic plastic welding machine description:

Ultrasonic plastic welding machine is mainly used for secondary connection of thermoplastics. Compared with other traditional processes (such as adhesive, electric ironing or screw fastening), it has significant advantages such as high production efficiency, good welding quality, environmental protection and energy saving. Ultrasonic plastic welding equipment is widely used in medical equipment, packaging, auto parts, fishing gear and other industries, such as disposable infusion filters and plasma separation cups, ziplock bags, plastic bottle caps, dishwasher water wheels, plastic toys, car lights, Welding of plastic fake fishing lures, charger housings and mobile phone slings, welding of a lighter housing, etc.
The NC series ultrasonic plastic welding machine can be used for butt welding of thermoplastics,such as the plastic door panel part for vehicle. It can also be used to replace the welding head according to customer requirements for riveting and welding. Welding, embedding, cutting and other processing techniques Our company has long been manufacturing body plastic parts, automobile doors, automobile car instruments, car mirrors, sun visors, interior parts, filters, reflective materials, reflective studs, bumpers, Cable, plastic filter for motorcycle, radiator, brake fluid tank, oil cup, water tank, fuel tank, air duct, exhaust gas purifier, tray filter plate; plastic electronics: prepaid water meter, communication equipment, cordless, Mobile phone accessories, mobile phone case, battery case, charger, valve-controlled sealed maintenance lead-acid battery, 3-inch floppy disk, U disk, SD card, CF card, USB connector, Bluetooth; toy stationery: folder, photo album, folding box , PP hollow board, pen holder, ink cartridge, toner cartridge; medical daily: watch, kitchen utensils, oral liquid bottle cap, drip bottle cap, mobile phone accessories, gold soft brush, daily necessities, hygiene products, children's products Air mattress, hanger, handle, gardening supplies, kitchen utensils, shower, gold soft brush, shower head, anti-counterfeit bottle cap, cosmetic bottle cap, coffee maker, washing machine, air dehumidifier, electric iron, electric kettle, vacuum cleaner Ultrasonic welding principle of speaker metal cover and civil grid:
Ultrasonic energy is transmitted to the weld zone by the upper weldment, and localized high temperatures are generated due to the large acoustical resistance at the weld zone, i.e., at the interface of the two welds. Moreover, due to the poor thermal conductivity of the plastic, it can not be dissipated in time and gather in the weld zone, so that the contact faces of the two plastics melt rapidly, and after a certain pressure, they are integrated into one. When the ultrasonic wave stops, let the pressure continue, and some pressure retention time, so that it is solidified, thus forming a strong molecular chain, for welding purposes, the welding strength can be close to the strength of the raw material body.
Ultrasonic welding application method 1. Welding method:
The welding head vibrating at the ultra-high frequency of ultrasonic waves makes the frictional heat of the joint surface of the two plastics melt and join at a moderate pressure. The welding strength can be compared with the body, and the watertight structure can be achieved by using suitable workpieces and reasonable interface design. It is airtight and eliminates the inconvenience caused by the use of auxiliary materials to achieve efficient and clean welding.
Second, the welding method:
The ultrasonic welding head of the ultra-high frequency vibration is pressed against the protruding tip of the plastic product, so that the instant heat is melted into a rivet shape, and the materials of different materials are mechanically riveted together.
Third, implant:
By means of the welding head and proper pressure, metal parts (such as nuts, screws, etc.) are squeezed into the plastic hole and fixed at a certain depth. After completion, the tension and torque can be compared with the traditional mold. The strength can eliminate the shortcomings of the injection mold damage and slow injection.
Fourth, molding:
The method is similar to the rivet welding method, in which the concave welding head is pressed against the outer ring of the plastic product, and the ultrasonic wave is ultrasonically shaped after the ultrasonic wave is ultrasonically welded, and the metal object is coated and fixed, and the appearance is smooth and beautiful. This method is often used in the fixed molding of electronic devices and horns, and the fixing of lenses for cosmetics.
Five, spot welding:
A. Weld the two plastic points without pre-designing the bonding wire to achieve the purpose of welding.
B. For relatively large workpieces, it is not easy to design the workpiece of the welding wire for point welding, and the welding effect can be achieved, and multiple points can be spot welded at the same time.
Sixth, cutting and sealing:
Using the principle of ultrasonic vibration generation, the chemical fiber fabric is cut, and its advantages are smooth and not cracked or drawn.
