How does linear vibration friction work?
Characteristics and Advantages
(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;
(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.
(3) Anti-clamping function: automatically reverse when meeting barriers;
(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)
(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;
(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;
(7) Bi-doors inter-locking: one of the door leaves always remains closing;
(8)Safety sensor terminal: sensor stops working when door closed;
(9)Unique coating technology: never rusty;
(10)Easy and convenient to install;
(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:
(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;
(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;
(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.
(4)Feet sensor switch applied to avoid contagion;

The principle of ultrasonic welding is to convert a 50/60 Hz current into 15, 20, 30 or 40 kHz by means of an ultrasonic generator. The converted high frequency electrical energy is again converted by the transducer into a mechanical motion of the same frequency, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator devices that can change the amplitude. The horn transfers the received vibrational energy to the joint of the workpiece to be welded, in which the vibrational energy is converted into thermal energy by friction to melt the plastic. Ultrasound can be used not only to weld hard thermoplastics, but also to fabrics and films.
The main components of a set of ultrasonic welding systems include ultrasonic generators, transducers / amplitude modulators / welding heads, molds and frames
Linear vibration friction welding uses the frictional heat generated by the contact surfaces of two workpieces to be welded to melt the plastic. Thermal energy comes from a certain pressure, a workpiece reciprocating movement on the other surface with a certain displacement or amplitude. Once the desired degree of welding is reached, the vibration is stopped and a certain amount of pressure is applied to both workpieces, allowing the just welded portion to cool and solidify, resulting in a tight bond.
How does orbital vibrational friction work?
Orbital vibration friction welding is a method of welding by frictional heat. In the case of orbital vibration friction welding, the upper workpiece is orbitally moved at a fixed speed - a circular motion in all directions. The movement produces heat that causes the welded portion of the two plastic parts to reach the melting point. Once the plastic begins to melt, the motion stops and the welded parts of the two workpieces solidify and are firmly joined together. Small clamping forces can result in minimal distortion of the workpiece, and workpieces up to 10 inches in diameter can be welded using applied orbital vibration friction.
