What are the application scope of ultrasonic lace machine? What is it for?

Ultrasonic welding is a high-tech technology for welding thermoplastic products. All kinds of thermoplastic adhesive parts can be welded by ultrasonic welding without adding solvent, adhesive or other auxiliary materials. Its advantages are to increase productivity, reduce cost, improve product quality and safety production.

The principle of the ultrasonic lacing machine is that the ultrasonic generator generates 20kHz (or 15KHz) high-voltage and high-frequency signals, converts the signals into high-frequency mechanical vibration through the energy conversion system, and applies them to the plastic workpiece. The temperature transmitted to the interface is increased by the friction between the surface of the workpiece and the internal molecules. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is rapidly melted, and then the gap between the interfaces is filled. When the vibration stops, The workpiece is cooled and shaped under a certain pressure at the same time to achieve a perfect welding effect.

ABS

Acrylonitrile butadiene

Phenylene copolymer is light in weight, with bremsstrahlung, rigidity and chemical resistance. It is widely used. This material has good thermal conductivity and is especially suitable for ultrasonic welding.

General purpose ps

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

Acrylics

Acrylic, high hardness, strong impact resistance, not affected by acid, high optical clarity, and good coloring. It is commonly used in car tail lights, signboards, medals, faucet handles, etc. When used for ultrasonic welding, attention should be paid to the problem of brightness attenuation.

Impact ps

Impact resistant polystyrene

Acetal

Acetal, high tensile and compressive strength, good wear resistance, and the strongest strength and strength. It is commonly used for splicing, screws, bearings, rollers, kitchen appliances, etc. due to low wear coefficient, ultrasonic welding requires high vibration amplitude and long welding time.

20-30% glass Filled PS

Glass reinforced polystyrene

Celluloeics

Ester acid is a kind of texture material, which is easy to change and change color during ultrasonic vibration. The contact surface is not easy to absorb energy, and it is difficult to weld.

Unmodified PP

Polypropylene, with light specific gravity, good insulation, high strength, heat resistance and chemical attack, can be made into rope and other fabrics after drawing. The products include toys, suitcases, music casings, electrical insulation, food packaging, etc. This material is easy to attenuate acoustic vibration due to its low elastic coefficient and is difficult to weld.

Noryl

Polyphenylene ether is widely used as electronic parts due to its strong properties, good electrical properties and high insulation. Due to the high melting point, the required welding time is long and the amplitude is high.

Filled PP reinforced polypropylene

Nylon

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

PVC

Polyvinyl chloride (PVC) is electrically stable, resistant to weak chemicals, good low temperature resistance, and flame retardant. It is commonly used in various synthetic leather hoses and films. 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 and filters. Because of the high welding point, the welding time is long. As the material is hygroscopic, it should be dried before welding.

Polyester; High welding energy

High Density PE

High density polyethylene, small specific gravity, flexible at low temperature and room temperature, waterproof, corrosion resistant, 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, willful, and long-term heating does not affect its electrical performance. It is commonly used for TV parts, such as the shield and motor parts. High energy welding is required due to high welding point.

Low Density PE

Low density polyethylene

Polypheny lene Qxide(ppO)

Polyoxyxylene is heat-resistant, moisture resistant, chemical resistant, and not afraid of steam. It is commonly used as terminals, rotors, shells, impellers and pipe fittings. It has a high melting point and requires high energy for welding

After the research, design and long-term improvement of our professional ultrasonic lace machine engineers, we finally solved the common problem of the domestic industry that the ultrasonic wave needs to stop blowing when it is hot, which often damages the power tube and can not work normally. The working time of the ultrasonic electric box is extended from 6-8 hours to 24 hours, the working temperature is increased from 28 ° to 75 ° and the machine is started normally.
