Low pressure casting uses positive pressure to move the molten aluminum (al si 7 mg) into the mold more quickly and achieves a finished product that is denser than a gravity cast wheel. Low-pressure casting has a slightly higher production cost over gravity casting, but offers superior durability and excellent value. The heat treating process reestablishes the structural integrity and strength of the material, which are compromised in the initial iron and steel work processes. High light technology (hlt) uses rollers to compress and elongate the material along the barrel of a low-pressure cast aluminum wheel to obtain the desired profile. This process, which is directly derived from o.z.'s experience in racing...(choose a part on the right to read more)
