O ring assembly machine
O-ring assembly machine that seats O-rings into the groove inside a lid or cap. Feeding and placement stations set to your lid size. Send a drawing for a quote.
What this machine is for
This machine fits O-rings into grooves on the part and presses each ring to depth. A ring that is cut, twisted or seated at an angle is the most common cause of a leak in the finished assembly, so the groove and the ring are the two things the tooling is built around.
How the line is built
Parts are loaded manually onto two vibration discs, which orient the ring and the part. Eight jigs, cut from die steel on a medium wire EDM, carry the parts through the pushing and rotary cam stations, and the ring is pressed into its groove before the part is released.
Control is a Delta PLC with a Wenview touch screen, and a safety grating plus guards on the moving parts are part of the standard build.
