Precise and consistent circular joining solutions across various industries.
We offer the broadest portfolio of joining technologies and provide unsurpassed technical support. Branson spin welding technology joins circular thermoplastic parts by applying pressure with a spinning motion that generates extreme heat to melt and fuse. This process creates durable seals every time for part-to-part interfaces that have a circular axis, such as a sphere, cylinder, disc or ring.?
Spin welding joins thermoplastic parts with a circular joint area by bringing the part interfaces together, under pressure, with a circular motion. Advantages for spin welding include strong, hermetic seals and its feasibility with most thermoplastic materials.
In the spin welding process one part is held stationary while the other is rotated and pressed against the stationary part. The spinning action creates extreme heat all along the circular join path. Extreme pressure is simultaneously applied by pressing the two parts together.? This combination of extreme heat and pressure fuses the plastic together along the path, creating a clean and instantaneous circular joint.
Spin welding is frequently chosen for joining together circular-shaped parts.?The typical RPM is in the range of 1500-2500 and weld force is 100-250lbs. Key applications include filtration, abrasive discs, irrigation, thermal cups, and automotive round lamps.
Branson’s SW-300 is a precision servo-driven spin welding system?capable of joining circular joint interface parts consistently with exceptional accuracy of +/-0.1 degree. It’s designed for fast, easy operation with color touch-screen and user-friendly human machine interface (HMI). Convenient preset and weld data information storage capabilities and linear encoder save set-up time. Our flexible system can be configured for your manufacturing environment, including manual, semiautomated or fully automated options.
Emerson is where technology and engineering come together to create solutions for the benefit of our customers, driven without compromise for a world in action.
