The Current Situation of Alloy Wheels' Technology and Equipment
The production equipment of forging alloy wheels is the same as the equipment of forging magnesium wheels. The difference of both is that it is to be protected the melting and pouring of magnesium forging wheels, while the casting and forging process of alloy wheels and magnesium forging wheels are the same.
The most advanced "Continuous Casting and forging" equipment of aluminum alloy wheels is born out of the "extrusion die forging machine" (or “liquid forging (forging melt) die casting machine”, “die forging machine”). And According to the characteristics of the alloy wheels, the equipment is made to the special machine.
This special machine which called alloy wheels, “Continuous Casting and forging”, the name can also be called “forging of the three low-pressure liquid forging the casting (melt forged) wheels machine.”
The installation of three large tonnage forging cylinder (one forging cylinder installed in series), in the rough alloy wheel casting filling pressure after the end of the forging force directly, respectively, the alloy wheels of the “hub”, “spokes” and the “rim “Independent forging, forging the alloy wheel to state organizations rough grain. The mechanical strength increased by 20% or more (ZL203 up to 390MPa), the elongation increased by 50% -100% or more (ZL203 up to 19.5%), shock increased 200% -500% (ZL203 up to 30), the surface's roughness of alloy wheel can reach to the highest —— 7-8 (roughness 1.6 – 0.8), which is comparable to machined out of the mirror reflection effect.
