Spin welding is a plastic welder frequently applied to plastic parts with a circular axis joint. This plastic welder produces Herculean bond strength. The friction welding of thermoplastic is based on the same principle as welding metals. During the spin welding process, one part remains stationary while the other part rotates against it at speeds up to 16,000 rpm. When the parts are pressed together, frictional heat causes the plastic to melt, and a bond is created upon cooling.

spin welderThe advantages of using a spin welder include the simplicity and reproducibility of the process. Plastic Assembly Systems produces the highest quality spin welding systems in the industry. PAS Models SW 750, SW850 and SW 950 are the results of new servo control technology. These three models offer the highest level of machine control available to date. They also make up PAS advanced line of spin welding equipment, showcasing dual servo control in the spin axis as well as the Z-axis. This allows precise control during the welding process. These state-of-the-art spin welding systems can be applied to run small, medium and large parts, offering maximum flexibility and opportunity. Spin welding is a quick process that works with large or small parts. Strong airtight seals are achievable in thermoplastic parts with a circular axis with spin welding.

Another advantage is that Plastic Assembly Systems’ spin welding systems can be used alone, or combined with other automation technologies to meet your criteria. Spin welding requires little maintenance and low power consumption. It’s also compatible with most thermoplastics.

Easily automated, spin welding confines heat to the interface of the joint areas. This is essential when trying to create a smooth-as-glass surface. Spin welding is just one of several friction welding devices. For information on spin welding and other forms of friction welding, visit our plastic welding resources section.
