Thermoplastic Joining Welder Ultrasonic Welding Machine of 15kHz Plastic Bonding Equipment for PVC_PP_Pet_PC_ABS Sealing WeldersThermoplastic Joining Welder Ultrasonic Welding Machine is the utmost prevalent ultrasonic assembly application, in ultrasound wave vibration bonding, the high frequency vibrating energy from a horn is applied to a work piece along with controlled pressure, which causes the joint area between two parts to heat up due to frictional heat, the plastic material melts and the parts are bonded together when the vibration stop, and the plastic solidifies, the process of ultrasonic welding is used to joint two thermoplastic parts together by applying controlled pressure to the parts and vibrating a titanium or plated aluminum horn vertically to generate frictional heat at the joint interface, the plastic is melted and then allowed to cool, and the clamping force is maintained during the hold time to improve the joint strength and hermetical, once the melted parts has solidified, the clamping force is removed, and the two parts are jointed integrally

Thermoplastic Joining Welder Ultrasonic Welding Machine of 15kHz Plastic Bonding Equipment for PVC_PP_Pet_PC_ABS Sealing WeldersThermoplastic Joining Welder Ultrasonic Welding Machine divides into four major components, composed of ultrasonic generator,viz: power box, transducer,Viz: converter, booster and horn/sonotrode,viz: acoustic tool, the ultrasonic generator converts standard electrical power into electrical energy at the required frequency, the popularity in ultrasound wave frequency definitely covers 15khz, and 20khz, the electric energy is them sent to the transducer, which change it into mechanical vibrations, a press and fixture are also required to complete the ultrasonic assembly system, but are not considered major components, the process is flexible and efficient, producing strong integral bonds which consuming very little energy, the booster is used to increase or decrease the amplitude of the vibration to match the required application, the amount of increase or decrease is expressed as the gain, which is the ratio of the output amplitude to the input amplitude, the vibrations are then transmitted to a horn of the appropriate size and shape to deliver the vibration energy to the work-pieces, the horn many further increase the amplitude of the vibration, and bottom fixture applies supportive holding in alignment and agglomeration, that is coupled with top hone in integration 
 

Buying Guides

 

Thermoplastic Joining Welder Ultrasonic Welding Machine has customized acoustic tools, that must be compatible with individual welds, particularly for joint design in the joining interface, that is critical in achieving optimum assembly results, the design depends on factors such as the type of plastic, the geometry profile and requirements of the weld, there are many different joint design, Each with its own advantages, some of these designs are discussed with the designer of injection mold, but, essentially following criteria, such as uniform contact area, small initial contact area, a approach of alignment and etc

Joint design for ultrasonic plastic welding

Sometimes while developing a new part for ultrasonic welding, the machine is working okay, the horn and fixture also well designed but if joint design for welding is not correct, it will create problem, the joint design must be considered in design stage of the product, If we are not giving any consideration for joint design, then, Patchy welding may occur, hermetic or leak proof sealing is not possible, more power will be required for welding, In ultrasonic welding, there are two basic joint types

Energy director joint: Energy director joint is preferable in amorphous structure material, sometimes in semi-crystalline material also this joint is given, the molten material builds at the contact area of the energy director between the parts to be welded, and the ultrasonic waves are transferred through the part to the energy director

01: tongue and groove joint

The joint consists of a small triangular section molded into the component and typically running the length of joint perimeter, the purpose of energy director is to focus the ultrasonic energy at the apex, resulting in rapid built up heat, this causes the triangular section to melt and flow across joint interface, forming a weld

The type of thermoplastic to be welded determines the form of the triangular energy director, amorphous material require a right- angled triangle with the 90 degree angle at apex, for semi crystalline material, a 60 degree equilateral projection is used, typical heights for energy directors are between 0.2 to 1mm depends on the material

Generally if we consider the wall thickness of part that is the thickness of wall on which energy director is to be formed as basis, and then height of energy director will be 1/8 of the wall thickness, the basic width will be 1/4 of the wall thickness

When the wall thickness enough to produce energy director that maximum size, more than one energy director can be given

This meets all three requirements

A uniform contact area

A small initial contact area

A means of self alignment

Its strength is relatively less than butt joints only a part of the wall in a step joint is welded, but it hides all flash inside, the material form the energy director will typically flow into the clearance gap between the steps

A step joint needs a minimum wall thickness of 2mm. the height and width of the step are each 1/3 of the total thickness, the step height should be marginally greater that the depth 0.1mm, this adds aesthetic to the welded assembly and hides parallelism imperfection in the molded parts
02: Shear joint

The shear joint is used when a strong, leak tight seal is desired especially with semi-crystalline polymers

A positive interference between the mating parts is a shear joint, the interference can only be melted away with ultrasonic energy, a shear joint meets all three basic requirements of good and joint design, a location recess help self alignment of the parts, and the line contact provide uniform contact area, small initial contact area, on application of ultrasonic energy and pressure, the contact surface rub together, generate heat and begin to melt and enlarge, till the designed depth of weld is achieved, as the contact surfaces melts, welding is achieved, the continuous smearing action of meting surface at the welding interface fills all voids, its also limits exposure to air, consequent premature solidification and degradation, this action produces a leak tight weld and strong structural strength, a fixture plays an important role in shear joint welding, and great care needs to be taken in designing it correctly, it should prevent a snap fit due to flexing of the walls during welding, the fixture should rigidly support the wall or fixture parts up to the joint interface, sometimes a spilt design or an ejector is necessary to eject the tightly squeezed in welding assembly from the fixture

Some other consideration

Several aspects need to be considered in deciding which part should make contact with the horn, and which part should be held stationary in the fixture

Ease of assembly, handing the individual components and part geometry are factors to be considered, from the ultrasonic point of view, however the material to be welded is important, losses in transmission of ultrasonic energy through amorphous resins are low and loses through semi-crystalline material are higher, this is because the orderly molecular structure of semi crystalline resins absorbs ultrasonic, where the random molecular arrangement of amorphous resins transmits ultrasonic well
