Ultrasonic Welding is the process of joining of thermoplastics through the use of heat generated from high-frequency ultrasonic acoustic vibrations. This produces a strong solid state joint. This process is used for joining dissimilar materials. This process is automated and extremely fast. It is accomplished by converting high-frequency electrical energy into high-frequency mechanical motion. That mechanical motion, along with applied force, creates frictional heat at the plastic components’ mating surfaces (joint area) so the plastic material will melt and form a molecular bond between the parts. Once the melted plastic has solidified, the clamping force is removed and the horn is retracted. The two plastic parts are now joined as if molded together and are removed from the fixture as one part.
Hot Gas Welding will work on most thermoplastics by joining components together, where adhesives or mechanical fasteners would be impractical, impossible or even prohibited. While there is no size limit, this welding process opens up new possibilities for your product development as well as adding versatility for joining same material components into permanent structures. Common materials welded are PVDF, Halar (ECTFE), PVC, PFA, Polypropylene and CPVC.
Fusion welding is also known as hot plate welding. It’s a process used to join two pieces of similar materials by melting them together. Melt squeeze must be allowed for when using this process but our technical expertise can help you in the design stage. This is an excellent welding process for multi-channel manifolds made from thermoplastics such as Polypropylene, Polyethylene, PVC, PVDF, Acrylic, Polycarbonate and other weldable materials.
A socket weld is used when you need a high leakage integrity and great structural strength. With this welding method, a pipe is inserted into a recessed area of a valve, fitting or flange.
Butt welding bonds two same materials which are nearly parallel but don’t overlap. The process involves heating the ends of two pieces of material to just over their melt point and joining them together under pressure to form a strong bond. The bond is about 90% as strong as the material. Butt welding is good for joining two flat sheets together as well as two pieces of pipe. Typical materials are PVDF, Polypropylene, HDPE Polyethylene and ABS.
