35KHZ 900W PZT8 High Frequency Ultrasonic Welding Vibrators For Plastic Welding Machine

Ultrasonic welding transducer It is usually used for plastic welding. It completely replaces the traditional industry of bonding with glue. In the ultrasonic welding process, there are no bolts, nails, snaps, welding materials or adhesives combined. It is faster than traditional adhesives or glues, and the drying time is very fast. The welding process can be easily automated and can be easily customized to suit all types of specific specifications.

The ultrasonic welding transducer converts the electron energy into mechanical energy, and then transmits the energy to the plastic bow and arrow only contact surface by the welding head (HORN), which causes the intense friction and heat generation between the molecules and the molecules, prompting the product to melt and combine instantly. Processing speed is fast, clean, beautiful and economical.

Welding range: toy industry, stationery industry, home appliance industry, electronics industry, food industry, communications industry, transportation industry, aerospace industry, etc.

Transducer type and maximum power: The manufacturer of the complete machine may have different regulations for the nominal power of the machine for different purposes and purposes. In other words, the nominal power of the same transducer used on different machines may be different. To avoid ambiguity, customers should specify the structure of the transducer, such as column type, inverted horn type, etc., as well as the diameter and number of piezoelectric ceramic wafers.

Installation and matching dimensions: mainly include the material of the horn, the surface treatment method, and the shape. The connecting thread of the transducer and the horn, the connecting thread of the horn and the mold, the diameter, thickness, number and position of notches or screw holes at the flange of the horn.

main feature:
High efficiency: high mechanical quality factor, working at the resonance frequency point can obtain extremely high electro-acoustic conversion efficiency.
Large amplitude: The structure optimized by computer has high vibration speed ratio and large amplitude of the front cover.
High power: Under the action of the prestressed screw, the energy of the piezoelectric ceramics can be maximized.
Good heat resistance: low resonance impedance, low heat generation, and wide operating temperature range. High reliability and long life.

The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.

Transducer requirements will depend on the application. Many requirements will conflict with one another and will be given different priorities. Hence, no single set of guidelines can encompass all requirements — i.e., there are many different ways to achieve the same objectives.

The applications of ultrasonic welding are extensive and are found in many industries including electrical and computer,automotive and aerospace, medical and packaging. Whether two items can be ultrasonically welded is determined by their thickness. If they are too thick ,this process will not join them. This is the main obstacle in the welding of metals. However, wires,microcircuit connections,sheet metal,foils,ribbons and meshes are often joined using ultrasonic welding. Ultrasonic welding is a very popular technique for bonding thermoplastics. It is fast and easily automated with weld times often below one second and there is no ventilation system required to remove heat or exhaust.
