Variant Alloy Wheels is proud to offer all our wheels using reverse-tilt moulding. Simply put, the reverse-tilt moulding process is the pouring of molten aluminium into a mould by tilting the mould to fill it in a controlled fashion. In traditional gravity casting the mould parting line is perpendicular to the floor during the solidification phase, while in reverse tilting the parting line is parallel to the floor. Turning the parting line allows the casting to be centre-fed similar to the way a casting is produced in the low-pressure process. Using reverse-tilt casting versus traditional gravity cast allows for more consistent pours and yields results that require less material to fill in air pockets normally found by gravity casting.
Here at Variant Alloy Wheels, we utilize a superior rotary forging technology known as, Cold Vertical Forging. This method allows us to use a much denser cast material which results in much lighter and stronger wheels than Low-Pressure Cast (LPC) materials, commonly used by other rotary forge/flow form wheel companies. By administering a steadier spin with consistent metal temperature Variant is able to produce a consistently higher quality wheel than hot horizontal flow form methods.
All Variant Alloy Wheels are constructed using our Cold Vertical Forging process. This technique employs hydraulic rollers with pressure on a pre-heated blank to stretch the barrel of the wheel to the specified diameter. While the wheel spins, the rollers stretch and compress the alloy material, thus enhancing overall structural rigidity and durability of the wheel. This procedure results in a wheel with much higher tensile strength (resistance of the material to breaking under tension) that is noticeably lighter.
