Key Technology:

  • Sleeving: This method of rim end joining uses an extruded aluminium insert matching the inner profile shape of the rim rather than pins. The sleeving method is usually used on rims that are lighter and considered to be of higher quality than pinned rims. The sleeve is typically about three inches in length. After cutting the sleeve blank off the extrusion, it is formed in a die to give it a radius to match the rim. The ends are also tapered to facilitate insertion in the rim voids.
  • Welding: The welding method is used on all levels of rims from OEM high volume rims to high quality after market rims. The method typically used is called a “flash-butt process”. The process is done in a large welder that grips the ends of the rim in clamps to hold and guide the rim during welding. The rim blank is rolled and cut with extra length circumferentially. The rim is clamped in the welder dies with the ends of the rim protruding about ¼" from the die on each side. The welder then starts the “flash” part of the weld cycle. It passes very high amperage current through the clamp dies while slowly moving one die to bring the ends of the rim together. The current creates an arc between the ends of the rim, burning off the extra metal allowed in the cutting of the rim blank while heating the ends of the rim. After a precisely controlled flash time, the current is turned off and the “butt” part of the weld cycle is initiated. This consists of rapidly forcing the heated ends of the rim together with great force to complete the joint. There is weld flash left around the weld that is removed to smooth the joint and blend it in to the extrusion shape.
