■The main technological process introduced

| ◆Low Pressure Casting Technology |
Low Pressure Casting is sealed in the crucible (or sealed cans), pass into the dry compressed air, liquid aluminum in pressure of gas, liquid or along the pipe through the gate into the cavity, to keep the pressure within the crucible under Solidification to shape, as a result of low pressure casting with a smooth filling and solidification pressure, and gravity casting and squeeze casting, compared with no internal porosity, less slag, high-density, high mechanical properties and dimensional accuracy. In the production, the casting is a very critical process.

Cast performance of a direct determines the rate of qualified products. The key lies in the low-pressure casting furnace pressure control accuracy and reliability of the equipment itself. Arays used by low-pressure casting machine are introduced from abroad. Equipment more rigid, have the opening and closing of the power module. Die-wide use of gas-cooled without Xiecha side of the cylinder mode technology. Hub is a leading low-voltage technology on behalf of those who.
CNC Machining: CNC machining of the wheels of the entire production process is the most important one of the links.

In order to meet the high quality of Arays awareness of the requirements and improve processing efficiency and the quality of processing. Arays to break the tradition of Canada (outside the lines to remove riser - rough outer position after the first car drilling) of the processing mode. Using high-precision dual-axis CNC vertical machining unit. In the industry for the first time Japan OKUMA CNC lathes and machining centers KIWA hub for processing. Turning to reach 3000r/min speed machining accuracy can be controlled in less than 0.001mm, product quality and safety performance has fully met the international advanced level.
Painting Process: Painting aluminum alloy wheel production is the last process.

which aims to improve the aluminum alloy wheel corrosion resistance and beauty! In order to achieve Arays "zero-defect quality consciousness". Shanghai Arays WANGER Germany to introduce automatic spraying to control the production line. The thickness of the coating to strictly control the precision of 10μm handling capacity of the surface up to international advanced level.

■Quality control process introduced
Quality Control is the root of living. Shanghai Arays always insist to regard ‘keep improving’ as the quality awareness and attitude to using on QC process. During the 12 years’ stride, Shanghai Arays has built a set of scientific quality control standard and inspection system. The carrying out of 3 steps inspection system, the control of 15 control points during the 7 links such as die-casting, machining, painting and so on, the overall control during the whole production process, all these make every product reach the requirement of ‘keep improving’.
The performance test is to test the performance index of aluminum alloy wheels by automatic testing instruments to analysis many kinds of normal and peak value and anomalous loading conditions.

This ensures the quality of products could pass even surpass the international JWL/VIA aluminum alloy wheel testing standard.
| ◆Mechanical properties test |
Mechanical Test: Mechanical test is to test the modulus of elasticity, strength, plasticity and such kinds of mechanical property of the aluminum materials after T6 heat treatment. The demands of Arays test items could respectively reach the highest level in the wheel industry to meet Arays’ high quality requirements. Tensile strength σb≥214Mpa, Yield Strength σ0.2≥114Mpa, Extensibilityδ≥7%, Hardness HB≥70
Salt spray test (with map):Salt spray test for testing the products quality of the appearance of anti-salt corrosion of the key, Many of Australia, American customers found that the seaside city in the wheel or rear-wheel wet road surface areas prone to oxidation, Mostly due to the wheel manufacturer does not carry out the experiment caused by salt spray.

In order to process the phenomenon, Shanghai Arays at internal for the first time will be used to support domestic OEM market that the salt spray test for the after-market products tested. Product lines engraved on the surface film of paint at the end of the extent of corrosion to be in control Wb ≤ 2.5mm and the film should not appear on the surface corrosion, foaming phenomenon. Arays this reform, a fundamental solution to the wheel surface oxidation corrosion. Become the hub model for wheels enterprises.
X-ray detection (with map): X-ray detection tests on the product quality to enhance the play can not be ignored.

Arays using German import testing equipment to detect. X-ray tube for the import of 160kVA metal tube that can penetrate more than 60mm of aluminum alloy pieces, clearly observed in-house products to state Shrinkage, pinhole defects, such as strict control in less than 50mm * 50mm. To ensure product quality and improve product safety performance, in full compliance with the requirements of awareness Arays.
Detection of dynamic balance (with map): a moving car, if not up to standard wheel balancing, or will have a swing beat, especially when the speed higher than 80km / h, swinging and jumping that will significantly increase.

The wheels are not stable, not only reduce the comfort and handling stability, the increase in fuel consumption, increased tire wear has a direct impact on the performance of the vehicles, damaged vehicles and other components. The existence of strict security. In order to improve the balance of aluminum alloy wheels, Arays of balancing the requirements of the test has been more than fully developed by industry standards.
Air tightness testing (with map): air tightness testing in the production of aluminum alloy wheel in the process of testing is very important. However, many factories had not paid much attention. Some manufacturers of products do not even try, or just missed by a certain percentage of sampling test for leakage. The only products not up to standard for simple fill gaps and will do. This is a very common home but very serious.

Arays Shanghai from its inception to always adhere to the "residue-free holes, no leakage, no complaints," called for strict implementation of products 100% of the entire gas-tight prosecution. Provides products in the 30s seconds wheel bubble phenomenon may not occur. To ensure that each product can reach Arays developed by quality.
