Ultrasonic spot welding equipment described car door car door ultrasonic plastic welding machine point, and may need to be replaced according to the product of the same mold spot welding, welding mold, chain welding mold, mold implants, embedding mold and mold removal. Ultrasonic welding mold by transferring energy to the welding area, vibration caused by friction in the local high temperature, but also because of poor thermal conductivity of plastic parts and can not heat, which results in the rapid melting of the contact surface of plastic parts, plus a manual pressure, to merge into one. Plastic spot welding mainly used in: car door, the car guard, car noise cotton, household appliances, non-woven products, stationery spot welding, mobile phone accessories, electrical parts riveting, automotive vehicle signs, folders and positioning riveting point welding process. Front and rear door Features ☆ spot welder Ultrasonic spot welding machine plastic sheeting for one design, compact and lightweight, retractable simple; ☆ portable ultrasonic plastic welder unique value in the door design, plastic shell, aluminum core, membrane switch panel; ☆ car door plastic welder overload protection device, FET output parts, mold automatic frequency tracking; ☆ car fender ultrasonic plastic welder three digit position DIP switch 0.01-9.99S ??exact time control; front door ☆ ultrasonic welder can be designed according to different products with different specifications of welding mold, respectively, to complete the welding, welding chain, implants, embed, removal processes. Car door ultrasonic welding machine welding method, welding: the ultra-high frequency ultrasonic vibration welding head under moderate pressure, so that two pieces of plastic joints create friction and instant hot melt bonding, welding strength can be comparable with the body, the use of appropriate and reasonable workpiece interface design, watertight and airtight, and eliminates the use of supplements inconvenience to achieve efficient and clean weld. 2, welding: the ultra-high frequency ultrasonic vibration welding head, pressing plastic products Shaotou prominent, it became an instant heat melt rivet shape, so that the material mechanical riveting different materials together. 3, implants: through preaching and proper welding head of the pressure, the moment the metal parts (such as nuts, screws, etc.) into a plastic squeeze reserved hole, fixed at a certain depth, regardless Rally is completed, the torque can be comparable within the traditional mold of strength molding, injection molding can avoid damage and slow injection of shortcomings. 4. Forming: This method is similar to the welding method, the concave shape of the welding head pressing on the outer ring of plastic products, welding hair out after ultrasonic vibration UHF melt molding plastic coated metal objects to secure it, and smooth and beautiful appearance, this method is often used in electronics, speaker of fixed shape, and the lens is fixed, such as cosmetics. 5, spot: the two plastic welding points without pre-designed wire, welding to achieve the purpose; the comparison of large workpieces, the workpiece is not easy to design the bonding wire welding points, and to weld effect, which can spot welding points. 6, cutting the seal: the use of ultrasonic oscillation moment works on synthetic fabric cutting, clean cut without cracking its advantages, not drawing.
