Sonic Friction Welder Ultrasonic Plastic Welding Machine

Sonic Friction Welder Ultrasonic Plastic Welding Machine

Sonic Friction Welder Ultrasonic Plastic Welding Machine has ultrasonic frequency:15khz,usually used for semi-crystalline thermoplastic working-pieces assembles in joints bonding, and ultrasonic output is ranged from 2600w to 5200w basing on various welding sizes. Its ultrasonic sonotrode or horn and anvil or fixture to hold the parts in applying pressure, the welding results is essential in selection of material and joining design in connecting interface

Machine Description

Sonic Friction Welder Ultrasonic Plastic Welding Machine

01: Application

Sonic Friction Welder Ultrasonic Plastic Welding Machine adopts ultrasonic bonding technique in parts assembling made of thermoplastic, is a process in which high frequency (ultrasonic) sound waves are applied to two or more work-pieces that are being hold together under pressure to fuse them into a single piece, commonly used to joint plastic parts, especially those made of different types of plastic,Sonic Friction Welder Ultrasonic Plastic Welding Machine permanently bonds the individual components without the need of adhesives or mechanical fasteners

Every Sonic Friction Welder Ultrasonic Plastic Welding Machine exerting bonding operation will vary based on the plastic material being joined, the shape of the work-pieces, and other factors, however, the overall process is generally the same. The parts being ultrasonically welded are fitted together and sandwiched between a metal nest or fixture, which holds them in place, and metal metal sonotrode or horn, the horn is connected to a transducer, which creates extremely high speed vibrations, the horn transfer this vibratory motion to the work-pieces it it pressed against, the vibrations cause the plastic to melt slightly, and pressure applied by the nest fuses them together, creating a joint typically, the interface area where the two parts come together is specially designed to facilitate the melting and bonding processes, after the parts are joined properly, the vibrations stop and the plastic cools very rapidly, creating an incredible strong bond

03: Emphasized Characters of ultrasonic bonding

Eliminate use of consumable material,likely adhesives, mechanical fastens

Because of molecular bonding process, can produce airtight and waterproof seams

Manual and auto production both are available in increasing production time

It is clean, reliable welding technique that may be applied to several manufacturing processes

Environment-friendly, ultrasonic bonding process don’t need consumable material

Usually it is characterized by cycle time that can reach below the second one, which makes it a widespread technique in industrial assemble lines

It guarantees uniform higher quality that lasts longer

Ultrasonic bonding process is achieved within seconds,which requires very low energy

The welding machine’s setup is very simple and once set it is reliable for a long period of time, this type of welding produces very little wear and tear of mechanical parts and no residues whatsoever

Heat-sensitive item can be assembled free of risk of getting damaged since ultrasonic welding produces minimal heating confined to the soldering point

04: Salient Features

Sonic Friction Welder Ultrasonic Plastic Welding Machine has found its relevance in most industries and applications due to its ability to blend with thermoplastic and other welding materials like polypropylene

Ultrasonic plastic welding uses the transmission of high-frequency ultrasonic acoustic vibration to heat, weld, solidify and last bond, all these processes occur very fast and allow you to weld more products within seconds, you will experience a high throughput and short turnaround times when you use ultrasonic welding

Ultrasonic plastic welding is safe to weld using the ultrasonic vibration frictional bonding, the procedure uses highly targeted energy, and this reduces injuries to the welders, the heat produced during welding is localized, minimal and quickly dissipated to the required welding joints and materials, this process does not cause any damage to the weds and the surrounding environment

Ultrasonic plastic welding machine is known to be durable, once they are assembled and tested, you an do mass welding with minimal breakdowns and faults, depending on your welding object, you may automate the process to reduce human intervention, this will reduce the operation costs and increase the quality of welds

Ultrasonic plastic welding machine can weld different materials, whether you intent to weld thermoplastic or metals, you can use the method without fear of uneven joints, the technique is widely preferred for welding dissimilar materials

Since ultrasonic welding is speedy, it takes less time, money and resources to complete a welding project, the welding process does not require connective bolts, solders and adhesive or other consuming material, as such, you realize a lot of savings in material cost, with high precision, ultrasonic welding gives you a smooth finish with minimal waste

The precision in ultrasonic welding guarantees high-quality joints, these joints will exhibit no plastic flashes, deformations, or faults, the result is clean and almost invisible seam that need zero retouches


Sonic Friction Welder Ultrasonic Plastic Welding Machine of 15khz has enlarged ultrasonic vibration energy to exert melting, particularly for semi-crystalline polymer, in addition, an energy director design is used with almost all ultrasonic welding plastic part design, except when the materials are semi-crystalline, as these have narrow glass transition temperature range they tend to move quickly into a liquid state rather than the gummy-ness typical of amorphous plastic, semi-crystalline material in bonding especially necessitates building in energy director with sharped apex to quick melting and solidifying at low energy consumption

Sonic Friction Welder Ultrasonic Plastic Welding Machine has 15khz and 20khz, but, for 20khz, its maximum power is 3200w, semi-crystalline material need strong ultrasonic energy in its bonding,15khz welder has maximum power 5200w, So, 15khz is usually proposed for big size of semi-crystalline material, keepleader has versatile models for option,such as table-top type, free-standing type, auto rotation indexing and horizontal, vertical type, in addition, we also can built integration of robotic arm for automatic loading and unloading, mount sound-proof cabin to reduce the ultrasonic sound in establishing cosy,clear and safe working environment

Machine Uses

Sonic Friction Welder Ultrasonic Plastic Welding Machine

Sonic Friction Welder Ultrasonic Plastic Welding Machine has capability in welding thermoplastic, all of amorphous likely PS, ABS, Acrylic,PC and PVC, and semi-crystalline likely HDPE,PP, Polyester and Nylon, particularly, semi-crystalline polymers are characterized by regions of ordered molecular structure, a high amount of heat is required to disrupt its ordered arrangement, the melting point is sharp, and re-solidification occurs rapidly, when in the solid state, semi-crystalline molecules are spring-like and absorb a large part of the ultrasonic vibrations instead of transmitting them to joint interface, so large amplitude is necessary to generate sufficient heat for welding, keepleaders technical team accumulate rich experience in selecting material and jointing design of connection interface and setup, believe that we can fabricate a reliable machine for your individual production
