After finalising the product drawings and 3D effects, product prototypes are produced.The customer will receive a prototype of the same quality as the large shipment and will even be able to install it directly on the car, use it normally, carry out various road tests and need to provide valuable comments in time.

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.

1. The size of the wheel is actually the diameter of the wheel. We often hear people talk about 15" and 16" wheels, where 15" and 16" refers to the size (diameter) of the wheel.2. The width of the wheel, commonly known as the J-value, has a direct impact on the choice of tyre. If tyres of the same size have different J-values, the flatness and width of the chosen tyre will be different.3. PCD and hole position, the professional name for PCD is pitch circle diameter and refers to the diameter between the fixing bolts in the centre of the wheel. The holes in the wheel are generally mostly 5 bolts and 4 bolts, but the distance between the bolts varies. the PCD is one of the most important parameters when choosing a wheel. For safety and stability, it is best to choose the same wheel as the original for the upgrade.4. wheel offset, in English Offset, commonly known as et value, is the distance between the bolt fixing surface of the wheel and the geometric centre line (centre line of the wheel cross section). Generally speaking, it refers to whether the wheel shrinks inwards or protrudes outwards after modification. For normal cars the ET value is positive, but for a few vehicles and some Jeeps it is negative.5. The wheel centre hole, the centre hole is the part used to fix the connection to the vehicle, which is the position of the wheel centre and the concentric circle of the wheel. The diameter size here affects whether we can install the wheel to ensure that the wheel rim geometry centre can match the wheel geometry centre. Although wheel shifters can convert the bore spacing, this modification is risky and should be tried with caution.

JWHEEL now stocks more than 4,000 sets of molds, which are stored on the shelves after use. Before production, the molds are sent to the workshop for comprehensive testing, cleaning, mold repair, pre-heating, painting, etc., and are fully prepared before being put on line for the first trial production to ensure product quality.

The wheels need to be packed according to the customer's requirements, conventionally with kraft paper and color box, non-woven dust bag or dust plastic bag, cap sleeve, protective ring, spacer, polyamide, pearl cotton, etc.The packaging is single or two-pack, according to the customer's demand, if the weight is too large only single pack, and will be tested before setting the packaging scheme.Warehouse storage will be in accordance with the weight of different sizes, placement height has relevant regulations.

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.

Generally, the medium used to detect air leakage in aluminum alloy wheels is water. The inner and outer sides of the aluminum alloy wheels are sealed by external force, and the whole wheel is immersed in water, and then air is injected into the inside of the aluminum alloy wheel. As the aluminum alloy wheel is a closed space, the entry of air will make the pressure inside the space rise, and if there are loopholes in the aluminum alloy wheel, the gas will be squeezed out from the loopholes and form obvious bubbles in the water. This method is generally called the bubble detection method.At room temperature and atmospheric pressure, helium is a colorless, odorless gas and is the substance with the lowest critical temperature ever discovered by man. Helium is a monatomic gas and is chemically inactive. Generally, helium does not produce compounds, but can be excited in low-pressure discharge tubes to form He+2, He plasma and molecules, which are widely used in military, scientific research, petrochemical, refrigeration, medical, semiconductor pipeline inspection, superconductivity experiments, metal fabrication, deep-sea diving, high-precision welding, and production of optoelectronic products. Since helium is an inert gas, it will not corrode the equipment application of helium mass spectrometry detector, can automatically distinguish the testing qualified and unqualified aluminum alloy wheels to different places, so as to reduce the quality risk of tires and prevent the safety hazards caused by tiny air leakage.First, the aluminum alloy wheel to be tested is sent to the specified position through the automatic running track, and the aluminum alloy wheel is centered and positioned, and the wheel is grabbed by the lifting and rotating manipulator onto the testing platform and waits for testing.Then, when the inspection platform detects a workpiece, the seal cover will be automatically closed; when the seal cover is lowered to the bottom, the booster cylinder above the seal cover will get a signal and an angled rubber pad inside the seal cover will be lowered under the action of the booster cylinder to seal the upper and lower part of the wheel. The pressure of the booster cylinder must reach 280kg-300kg to ensure that the gasket can be effectively sealed.Under the pumping force of the vacuum pump, the one-way connection to the vacuum pump will be automatically opened to pump the vacuum inside and outside the cavity. The vacuum value inside and outside the wheel reaches 012 mbar, and then the one-way valve is closed. When the vacuum reaches the set value of the equipment, the equipment will automatically input the test gas to the outer cavity of the wheel hub through the pressure valve within the specified time, in which helium accounts for 10%-12% of the test gas, the test pressure is 2500mbar~3000mbar test gas is kept in the sealed vacuum chamber for about 6s, the one-way valve connected to the mass spectrometry leak picker will open, if the aluminum alloy wheel hub If there is a leaky hole in the aluminum alloy hub, the helium molecules will enter the mass spectrometry leak detection analyzer through the leaky hole in the hub via the one-way valve for analysis, and the one-way valve will be closed after opening for a certain time to prevent the air from entering the mass spectrometry leak detection analyzer and causing damage to the mass spectrometry leak detection analyzer.Finally, according to the comparison between the value of the mass spectrometry leak detection analyzer and the set value of the equipment, the system will determine whether the aluminum alloy wheels meet the basic quality requirements of the application, and automatically distinguish the qualified and unqualified tires, and place them in different turnover lanes and then after the test is completed, the recovery pump will recover the excess detection gas to complete the whole process of testing.JWHEEL is using helium testing technology to improve product quality with efficient testing methods.

The wheels produced by JWHEEL, after CNC machining, need to be inspected by the assembly line and have no obvious surface defects before continuing to the next process.Common defects are, clear bump, serious deformation, scratches, burrs, flying edges, etc., which need to be scrapped or reworked according to the situation.

Automotive aluminum wheel coating production line1. Pre-treatment process of automotive aluminum alloy wheel coating production linePre-treatment process is the process of passivation film treatment for the treated aluminum alloy wheels in the coating process. According to the generation of passivation treatment film, it can maintain the wheel rim from environmental pollution such as soil and waste water in the car driving, prevent the leaching caused by the road environmental pollution touching the aluminum alloy wheel hub for a long time in the driving, and improve the service life of the aluminum alloy wheel hub of the car. When carrying out the processing technology of aluminum alloy wheel preparation treatment, the general self-injection type of machine and equipment is selected. By studying past information and practical applications, the author found that pretreatment of automotive aluminum wheels by spray-type equipment can ensure that aluminum alloy wheels can form a comprehensive passivation film more extensively than other pretreatment equipment.2、Grinding process of automotive aluminum alloy wheel coating production lineAt present, the commonly used automobile aluminum alloy wheel grinding equipment mainly includes angle grinder, surface grinder, air grinder, etc. When grinding automotive wheels, it is necessary to choose the appropriate grinding equipment for grinding according to the actual situation of the wheels. For the irregular shape of aluminum wheels and mechanical equipment with pipe grooves, the plane grinding machine can be used to solve the grinding plan, the corner grinding machine can be used to solve the parts with large pipe grooves, and the pneumatic head can be used as the processing equipment to solve the small pipe grooves. After carrying out sanding treatment, the waste produced is easy to make the operator injured, while the range required for sanding equipment is much wider.Wearing the appropriate protective clothing, there are also companies that need to set up special grinders. Before grinding, the wheels must be thoroughly inspected, the exact location and degree of grinding must be determined, and an appropriate construction plan must be drawn up for grinding. After the grinding is finished, the secondary inspection and processing of the automotive aluminum wheels is needed to ensure the quality of the polished equipment, improve the aesthetic appearance and confirm that there are no grooves and protrusions before the painting process.3、Powder spraying process of automotive aluminum alloy wheel coating lineAfter the pre-treatment and grinding process, it is necessary to carry out powder coating treatment on the automotive wheels. The initial formal process of the aluminum alloy wheel coating process is that, by carrying out powder coating operation on the automotive aluminum alloy wheels, it is possible to produce a flat cover by spraying paint to the finished grinding automotive wheels, and at the same time, the thickness of the spray powder is usually chosen to be 100μm when carrying out powder coating treatment, which can improve the wheel's It can improve the aesthetics and corrosion resistance of the wheels, effectively meet the current requirements of the wheels for driving, improve the life of the wheels, and realize the basic guarantee of the driver's life safety.After the powder coating operation of aluminum alloy wheels, the powder coating can review the defects existing on the surface of the wheels and lay a solid foundation for the next coating technology. At present, auto parts manufacturers have realized the assembly line production of powder spraying technology. The specific production line includes thermal energy system, curing oven, chain conveyor, production waste recycling equipment, powder blasting workshop and powder blasting gun. Through the above automated sandblasting processing, can significantly reduce the investment in human resources when sandblasting operation, improve the safety of sandblasting processing.4、Spraying process of automotive aluminum alloy wheel coating production linePainting technology is the last process of the automotive aluminum wheel coating production line technology. By painting the automotive wheels, it can not only improve the aesthetic appearance of the car, but also further strengthen the anti-corrosion ability and anti-stoning ability of the automotive wheels. There are two kinds of paints and varnishes commonly used to carry out the coating treatment. The operating environment of aluminum wheels is not good, and when the painting process is carried out, three painting rooms are usually reserved in the wheel treatment line so that the automotive wheels can be adequately painted and treated.Meanwhile, in order to improve the painting quality of the automotive aluminum wheels after painting treatment, acrylic painting is usually chosen to treat the automotive wheels. By treating the color paint as well as the varnish with acrylic baking paint, it can effectively eliminate the situation of color difference in the wheel painting. There are two main types of painting technology: manual painting and automatic painting. Manual painting requires a high level of operator skill. For manual painting operation, the operator should have sufficient painting experience to ensure that the surface of the aluminum alloy wheel is evenly painted and has a flat appearance after painting treatment.
