1. Clothing industry : the processes before stitching underwear briefs, welding ribbon, elastic rope ,etc; Also can be used for adorn article on some drill. 

2. Label industry : woven label, printed label, etc. 

3. Automobile industry : the soundproof cotton of car door,the base of windscreen wiper ,engine cover,radiator cover,auto dashboard,bumper,car door panel and so on. 

4. Plastic electronics industry : the small pieces of plastic riveting. 

5. Household applications industry : for fiber cotton spot welding, etc.

BANRY Ultrasonic Mini Spot Welder BR-28DH/BR-20DH is composed of ultrasonic transducer (converter), cover, horn (sonotrode) and generator.

Our company can supply you a variety of special or general ultrasonic spot welder according to your requirements.

♦ Principle  of Ultrasonic Plastic Woven Fabric Cutting

When ultrasonic wave contact on the surface of the thermoplastic plastic, which will produce high frequency vibration tens of thousands of times per second, we called high frequency vibration. Through ultrasonic mold (sonotrode, horn) transfer ultrasonic energy to the ultrasonic welding material surface, so the material can produce high temperature to make the plastic contact surface rapidly melting, coupled with pressure, make its be in harmony are an organic whole and solidification molding, thus achieve the goal of ultrasonic welding.

Ultrasonic welding :

ultrasonic vibration with ultrasonic welding mold (sonotrode, horn), ultrasonic energy conduction to the surface of plastic welding surface, thus produce local high temperature to make the melt plastic surface. Under the pressure of ultrasonic handheld, the plastic welding material can be welded well, beautiful and strong effect.

Ultrasonic preparetions :

When placing plastic nut screw or other metal work pieces., ultrasonic welder would transmit the ultrasonic energy to metal, and after high speed vibration to produce heat , the metal will  directly embedded in the plastic.

Ultrasonic riveted :  

Whe you need joint metal and plastic or two pieces of properties of different plastic, please use ultrasonic riveted method, which makes the weld material difficult to embrittlement, beautiful and strong. 

Ultrasonic spot welding : 

Use of ultrasonic small welding head (sonotrode, horn),  let two pieces of plastic products to be divided into multipoint welding point, or a whole row of teeth sonotrode weld pressure on the two plastic parts directly, so as to achieve the effect of ultrasonic spot welding. 

♦ Advantage

1. Portable type, convenient operation .

2. Gun type, straight type, feel comfortable, fast welding speed .

3. Fine welding effect .

4. Fine economy: need not glue, save materials and artificial, reduce the cost . 

5. Optimize the hot welding defects, such as yellow, burning and too thick .
