Usually the triangular part of the connection will gather ultrasonic energy and quickly melt to form a welding surface. From left to right, the butt joint, step type and mortise type are
Suitable material for ultrasonic welding
Suitable material for ultrasonic welding.
1. Ultrasonic welding is suitable for all thermoplastics, amorphous plastics such as ABS,PMMA,PC,PS; Semi-crystalline plastics such as PA,PET,CA,POM,PE and PP.
2. Ultrasonic welding is also suitable for non-textile fabrics, such as thermoplastic fabrics, polymeric materials, coated paper and mixed fabrics.
3. Flexible material: refers to soft material with low elastic modulus.
4. Rigid materials: refers to high elastic modulus and low mechanical vibration damping factor materials, such as polystyrene (PS), polymethyl methacrylate (PMMA), polyamide (PA).
5. All polymer films, molecular synthetic fibers, cloth composed of films and fibers.
Ultrasonic welding fusion interface design.
Ultrasonic plastic weld generally requires the welding interface to be small, the contact surface to be unified. The interface design depends on the material of the weld, the shape of the weldment and the requirements of the weldment.
Usually the triangular part of the connection will gather ultrasonic energy and quickly melt to form a welding surface. From left to right, the butt joint, step type and mortise type are .
The shear type is suitable for sealing plastic or where the plastic rapidly changes from solid to molten within a narrow temperature range.
Characteristics of ultrasonic welding
Ultrasonic has a wide range of applications, energy saving, environmental protection and high precision.
1) Advantages of ultrasonic metal welding:
a, the welding material is not molten, not fragile metal characteristics.
b, good electrical conductivity after welding, very low or almost zero resistance coefficient.
c, low requirements for welding metal surface, oxidation or electroplating can be welded.
D. Short welding time, without any flux, gas, solder.
e, welding without spark, environmental protection and safety.
2) Advantages of ultrasonic plastic welding machine:
A. Fast welding speed, high welding strength, good sealing;
b, replace the traditional welding/bonding process, low cost, clean and pollution-free and will not damage the workpiece;
c. The welding process is stable, and all welding parameters can be tracked and monitored by the software system. Once faults are found, it is easy to eliminate and maintain them
Application of ultrasonic welding equipment
1) Automobile: ultrasonic can be controlled by computer program to implement welding of large and irregular workpiece such as: bumper, front and rear doors, lamps, brake lights, etc.
2) Home appliances: through appropriate adjustment can be used for: portable solar lampshade, steam ironing door, television enclosure, collection, audio machine transparent panel, power rectifier, TV housing screw fixing seat, washing machine sink and other household appliances need to be sealed, firm and beautiful.
3）Packing: Hose seal, special packing belt connection.
4) Toy industry: Because of the use of ultrasonic technology to make products clean, efficient, firm, avoid the use of screws, adhesives, glue or other auxiliary products, reduce production costs, so that the competitiveness of enterprises in the market is greatly enhanced
5) Electrical engineering: plug, wire plug, contact reed, socket, wire reel, spool, contact piece, fluorescent tube box, electric fuse, relay switch, plug injection parts, printed circuit board, fuse box, etc.
6) Other commercial uses: from communication equipment, computer industry, printing equipment to audio-visual products, etc., ultrasonic equipment can be used.
