Low Pressure heat treated process
Aluminum ingot is melted into aluminum water through the melted furnace with high temperature. Aluminum water will then be low pressure injected into the mould to create a low pressure cast wheels. The resulting casting is all x-ray inspected to ensure no junctions, porosity or cavities. After heat treatment, casting wheels are subject to series testing including run-out testing, balance testing and air tightness testing until they are proved qualified for the final finishing process.
Due to the characteristics of low-pressure casting process, different types of defects such as cracks, inclusions, shrinkage, porosity, etc. cannot be avoided, and the resulting defective products account for more than 90% of the whole unqualified products, so the existence of these defects affects the qualification of the wheel, and the use of detection means to detect the qualification of the wheel has become an indispensable part of the wheel casting industry. JWHEEL uses nondestructive detection methods, usually X-Ray inspection is the first process after the low pressure casting wheel is formed, and it is used to detect the above internal casting defects to prevent the defective products from continuing the subsequent process and wasting resources. The X-Ray inspection is used to detect these internal casting defects as the first process after the low-pressure casting wheel, so as to avoid the waste of resources in the subsequent process.
JWHEEL Low Pressure Casting Wheel Pouring.
The aluminum water, which is about 700℃ or above and well mixed, is transported to the machine with special equipment and safely poured into the low-pressure casting equipment. The transportation process needs to pay attention to the safety of personnel and the operation of the machine to make sure it is 100% safe before operation.
JWHEEL has 17 gravity casting machines. The gravity casting wheels are processed and shaped, the surface inspection is OK, and the sprues need to be knocked off and put into the tooling for transportation to the CNC machine for product processing.
Visual inspection is the first inspection item, which can avoid serious quality problems from flowing out continuously and adjust the process in time, such as serious deformation, air holes, pin holes, missing material, etc., which seriously affect the product quality.
The product needs to be fully inspected and production recorded to be able to track the product production process.
Gravity casting wheels, need to pay attention to the temperature of the aluminum water, the volume of input, the processing process pay attention to the safety of personnel, the first inspection process after the mold is a visual inspection, need to detect whether the mold has pinholes, air holes, etc., the shape is complete.
The wheels produced by JWHEEL pay great attention to the mixing ratio of aluminum alloy, which needs to be purified before and after mixing to ensure the temperature of aluminum alloy and the mixing ratio.
A356.2 is used for the production of cast wheels. A356.2 alloy is a typical ternary alloy of Al-Si-Mg system, which is a casting aluminum alloy with excellent overall performance. It not only has good casting properties (good fluidity, small linear shrinkage, no thermal cracking tendency) and can cast thin-walled and complex-shaped castings, but also can achieve the ideal combination of high strength, good plasticity and high impact toughness through heat treatment, so it has become the material of choice for automotive cast aluminum wheels.
Forged wheels are custom built to order. Forged wheels are strong, dense, yet very light wheel that high performance car enthusiasts use for their cars almost exclusively. The term “forged” refers to making an alloy wheel by forcing a raw block of metal into a shape with extreme pressure. Forging is an expensive, multi-stepped process and typically take around 4-6 weeks to deliver.

Gravity casting is a method of manufacturing a cast wheel of an specific metal alloy, typically aluminum, although Magnesium is also used, which involves supplying molten metal to a mould cavity via a feeder through a running system where the molten metal entry point is located above the top of the mould cavity. In this manufacturing process all the metal entering the mould is subject to turbulence. This turbulence can cause severe defects such as oxide inclusions and entrapped gas porosity and in some cases mould erosion and hotspots.
There are significant advantages to forged wheels such as forged wheels being 3x stronger and 25% lighter which is everything you want in a dedicated race car. The down side is that it costs 3x as much than a cast wheel.
