接部分の強度は、他の部分よりも低いため、溶接部の品
質保証の問題、そしてその溶接部分は他のリム部分と比
べて比重が異なるために、回転バランスが採りにくい
他、成形が多工程に亘るなどの問題があった。Conventionally, wheel rims have been manufactured by cutting a rolled plate of steel or aluminum alloy into a certain size, winding the plate into a ring shape, terminal molding and then flash butt welding, burr cutting, planer and side burr cutting. There has been a method of performing roll forming after finishing treatment. However, not only is the welded portion prone to defects and a 100% air leak check process is required, but the strength of the welded portion is lower than other portions, so the problem of quality assurance of the welded portion, and the welded portion Since the specific gravity of the rim is different from that of other rims, it is difficult to balance the rotation, and there are problems that the molding involves many steps.
また、継目なしリムを実現するためには、押出しパイプ

押出し後に数回の引抜き加工を施す必要があり、パイプ
コストがべらぼうに高いものとなるばかりか、肉厚の均
一性が得られない等の問題があった。Further, in order to realize a seamless rim, there is a method of using an extruded pipe as a material, but since it is difficult to extrude a large-diameter thin-walled pipe corresponding to the rim diameter and the wall thickness,
Since it is necessary to perform drawing several times after extrusion, there are problems that not only the pipe cost becomes expensive but also the wall thickness cannot be uniform.
