Ultrasonic welding and plastic properties

ultrasonic welding, such as strength, plasticity, toughness (brittleness), hardness and so on, is a high-tech technology for welding thermoplastic products. All kinds of thermoplastic rubber parts can be treated by ultrasonic welding without adding solvents, adhesives or other auxiliary products in the deep development stage of industrialization, informatization, urbanization, marketization and internationalization in China. Its advantage is to increase productivity, reduce costs, improve product quality and safety in production

the principle of ultrasonic plastic welding is that the generator generates 20kHz (or 15KHz) high-voltage and high-frequency signals. Through the energy conversion system, the signals are converted into high-frequency mechanical vibration, which is added to the plastic product workpiece. The temperature transmitted to the interface is increased through the friction between the workpiece surface and internal molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface will melt rapidly, and then fill the gap between the interfaces. When the vibration stops, At the same time, the workpiece is cooled and shaped under a certain pressure to achieve a perfect welding effect

abs acrylonitrile butadiene

phenylene copolymers are light, with bremsstrahlung, rigidity and chemical resistance. They are widely used. This material has good thermal conductivity and is especially suitable for ultrasonic welding

General purpose PS general purpose PS has light specific gravity, strong corrosion resistance to water and chemicals, good stability and insulation. It is especially suitable for injection and extrusion molding, and is commonly used in the manufacture of toys, decorations, cup washing equipment, pans, lenses, floating wheels, etc. Due to its high elastic strength coefficient, it is suitable for ultrasonic welding

acrylics acrylic

it has high hardness, is resistant to heavy blows, is not affected by acid, has a high degree of optical clarity, and has good coloring. It is commonly used in car tail lights, cosmetic boards, medals, faucet handles, etc. When used in ultrasonic welding, attention should be paid to the problem of brightness decay

impact PS impact resistant polystyrene

acetal

high tensile and compressive strength, good wear resistance, and the strongest bremsstrahlung and strength. It is commonly used for splicing, screws, bearings, rollers, kitchen utensils, etc. due to its low wear coefficient, high vibration amplitude and long welding time are required when using ultrasonic welding

% glass

filled PS glass reinforced polystyrene

celluloeics ester acid woven dimensional material

when ultrasonic vibration, the material is easy to change color, the contact surface is not easy to absorb energy, the welding is difficult, and the requirements for plastic technology will be more stringent and difficult

unmodified PP polypropylene

has light specific gravity, good insulation, high strength, heat resistance and chemical erosion, and can be made into rope and other fabrics after tapping. Products include toys, suitcases, music casings, electrical insulation, food packaging, etc. Due to its low elastic coefficient, this material is easy to attenuate acoustic vibration and difficult to weld

noryl polyphenyl ether

has brevity, good electrical properties, high insulation, and is commonly used as electronic parts. Due to the high melting point, the required welding time is long and the amplitude is high

filled PP reinforced polypropylene

nylon

material is strong, wear-resistant, extremely low friction coefficient, acid resistant, commonly used as bearings, gears, pipes, kitchen utensils, brushes, etc. When using ultrasonic welding, due to the high melting point and long welding time, it is easier to weld after drying before welding

pvc

electrical property, resistance to weak chemicals, good low temperature performance, and flame retardancy. It is commonly used in all kinds of leather hoses, film, etc. on February 9, 2018. The material is soft, easy to attenuate acoustic vibration, and the welding surface is easy to deteriorate

p.c. polycarbonate

heat resistant, excellent transparency, high tensile and bending strength, commonly used in lenses, such as heat pipes, filters, etc. Due to the high welding point, the welding time is long. As the material is hygroscopic, it should be dried before welding

polyster polyester

large welding energy

high density PE

low specific gravity, flexible at low temperature and room temperature, waterproof, corrosion-resistant, and can be made into various colors. Products with low price are commonly used in dish pan, packaging film, soft water pipe, milk bottle, soft rope, etc. The higher the density, the more suitable for ultrasonic welding

polysulfone

polysulfone is hard, strong, capricious, and does not affect its electrical performance when heated for a long time. It is commonly used as TV parts, motor parts, etc. Due to the high welding joint, higher energy welding is required

low density PE low density polyethylene

polyphenylene Qxide (PPO) polyoxyxylene

heat resistance, moisture resistance, chemical resistance, not afraid of steam, commonly used as terminals, rotors, shells, impellers and pipe fittings, etc., with high melting point, requiring higher energy fusion
