Spin Welding

Spin Welding

Spin Welding is the technology of choice when assembling round or cylindrically shaped parts and in particular, parts molded in semi-crystalline materials. During the spin welding process, one plastic component is spun against a mating plastic component that is held stationary in a nest. The friction created by the spinning of one part against its mating part, under applied pressure, generates heat to melt and fuse the two plastic parts together.

LEFT: Manually operated pneumatic spin welder. Operator loads part into a three jaw chuck. The other mating part is nested in a locking fixture so it will not spin with the mating piece. Depressing the green button starts the welder and the two parts are fed together by simply swinging in the handle shown in white.

Recently, Tooltex engineers developed a revolutionary product that can control all aspects of your weld. The new "SCSW-1050" is based around a 5hp servo motor. The drive controls are very simple allowing operators or maintenance to adjust parameters to the perfect weld. The entire head is driven on a set of linear bearing ways attached to a pressure switch feeding information back to the drive. With this switch, you can adjust how much pressure is applied before the start of the weld. The head down actuation is done with simple pneumatics. Your parts are not in a straight down path? Thats okay, this unique head also is designed for pivot in the "YZ and XZ" axis. So how is the part held in the drive tool? We have developed a vaccum system that allows all parts to spin and keep vaccum on your part. It does not require any moving fittings or airlines. Again, keeping it simple.
