Forged alloy wheels, with their advantages of high strength and lightweight design, have become the core choice for car modifications and premium vehicle models. Their exceptional performance stems from a precise manufacturing process. From raw aluminum ingots to qualified finished products, every step hides the mysteries of craftsmanship. Below is a concise analysis of the key stages:

Raw material preparation is the cornerstone of quality. T6061-T6 aerospace-grade aluminum alloy ingots specifically for forged wheels are selected. These ingots are melted at 700°C, with alloy components adjusted, then cast into solid aluminum billets which undergo homogenization treatment to eliminate internal stresses, ensuring uniform material properties. This step provides a stable and reliable base material for subsequent forging, serving as the core guarantee for wheel strength.

 

Forging is the critical process. After cutting, the aluminum billet is heated to 400-500°C, first pressed into a disc shape by a upsetting machine, then pre-shaped with a pre-forging die, and finally forged into its final form under a multi-ton hydraulic press. During the final forging, metal grains form dense flow lines, making the wheel strength far exceed that of cast products. The durability of factory-direct custom forged wheels originates from this process.

The heat treatment stage further enhances performance. The wheel blank undergoes solution treatment at 520°C, water quenching cooling, followed by artificial aging treatment at 120°C for 8-12 hours, significantly increasing hardness and tensile strength to meet the complex stress requirements of vehicle operation.

 

CNC machining ensures precise fit. Through CNC equipment, the rim is turned, spokes are milled, and bolt holes are processed, with dimensional tolerances controlled within ±0.05mm to guarantee dynamic balance and installation compatibility. Subsequent surface treatment combines aesthetics and protection: after sandblasting and phosphating pretreatment, processes such as powder coating, electrophoresis, or vacuum electroplating are used to create a variety of colors and textures.

Finally comes the rigorous testing phase. Finished products must pass X-ray flaw detection, dynamic balance testing, bending fatigue testing, and other inspections. Only 18-inch lightweight forged wheels that pass all tests, with specifications marked, can be shipped out.

 

Although the manufacturing process of forged wheels has been streamlined, it always adheres to the core standards of 'precision and toughness'. The strict control at every step from raw materials to finished products not only achieves their excellent performance but also makes it easier for car owners to understand the key to quality when making a choice.

 

 

In the field of personalized car modification, the color of forged wheels is not only an expression of visual aesthetics, but also the finishing touch of vehicle temperament. From classic versatility to distinctive personality, the surface color selection of forged wheels is rich and diverse, and different tones can give vehicles a completely different style. Below is a detailed analysis of the mainstream forged wheel colors and their characteristics, accompanied by real-life photos for intuitive presentation.

 

Classic and versatile color schemes: timeless choices 

1.Matte Black, as the "evergreen tree" of modification circles, matte black wheels are known for their low-key and steady texture. Its frosted surface can effectively hide small scratches and dust, making daily maintenance extremely convenient. Whether it is a family car or a performance sports car, it can be perfectly adapted. When paired with a white or dark body, the visual impact is particularly prominent. 

2.Glossy black: The gloss black wheels interpret a luxurious and sporty feel with a mirror like highlight effect. The smooth surface reflects light like a black gemstone, adding a strong sense of fashion to the vehicle. Suitable for car owners who pursue delicacy, especially when paired with black and white body, it can form a classic visual combination of "Black Warrior" or "Panda Eye". 

3.Silver is the most regular and classic color for original wheel rims and also the most versatile "universal color" for compatibility. The silver wheels with metallic texture can highlight the delicate patterns of forging technology. Whether the body is bright colors or stable neutral colors, they can blend harmoniously, balancing practicality and low-key texture, especially suitable for business vehicles or car owners who value value value.

 

Personalized advanced color scheme: showcasing unique taste 

4.Gun gray (gunmetal-wheel) is between black and silver, with a cool color tone that comes with "combat attributes" that gives the wheels a sense of power. Its dark gray background has a subtle metallic luster, neither too dull as black nor more sporty than silver, making it a popular choice for performance car modification. When paired with red, blue and other body colors, it can create a strong track atmosphere. 

5. Golden wheels are synonymous with high-end and luxury, commonly seen in supercars or limited edition models. The warm metallic luster can instantly enhance the vehicle's attractiveness, like "golden armor" embedded in the wheels, but it requires higher color requirements for the body, and is more suitable for matching with solid color bodies such as black and white to avoid excessive color clutter.

 

Trendy bright color scheme: unleashing ultimate personality

6.Blue wheels break tradition with a fresh and vibrant visual effect, with light blue like the sea breeze brushing against the face and deep blue like the night sky, suitable for car owners who pursue youthfulness and personalization. When paired with a white or light gray body, it can create a sharp contrast and inject a lively atmosphere into the vehicle, but attention should be paid to avoiding excessive overlapping with the same color body, which can cause visual fatigue. 

7.Red wheels are a symbol of passion and speed, with bright colors like flames on the racetrack that can instantly ignite the vehicle's sporty genes. Suitable for pairing with neutral colors such as black and white as the finishing touch of the car body, but requires more frequent cleaning in daily use to maintain a bright appearance, suitable for trendy players who love modification culture.

 

In car after market, the core of selecting forged wheel is to "adapt to the car model+meet the needs". For sedans,  SUV,  new energy vehicles,  the differences in the characteristics determine vastly different standards for wheel hub selection. So how should different car models choose forged wheels? 

Base on the core requirements, combined with parameters and scenarios, we provide below suggestion for customers to choose suitable Aluminum forged wheels.

 

Sedans are mainly used for daily commuting, and the selection should take into account "lightweight+comfort". On the basis of basic parameters, it is recommended to have a diameter of 16-19 inches, as excessive diameter may reduce the shock absorption effect. Family sedans can choose 17 inch forged wheels, with lightweight design to reduce fuel consumption, suitable for most compact and medium-sized cars; Sports sedans can try 18 inch 5-hole sports forged wheels, with ET35-45 offset to improve handling stability, and classic black and silver color matching for a more dynamic look. We recommend styles with moderate hollow out ratios for the spokes, which balance heat dissipation and aesthetics, and are suitable for daily use scenarios.

 

SUV need to cope with both urban and off-road road conditions, with the core being "high intensity+passability". The recommended size is 18-20 inches, with a width of 8.5-9.5J and wide tires to enhance grip. T6061-T6 high-strength aluminum alloy forged wheels are preferred as the material, with outstanding tensile strength and impact resistance, capable of handling off-road bumps. Hardcore off-road SUVs can choose ET 0-15 negative offset wheels to widen the wheelbase for greater stability; Urban SUVs are suitable for zero offset or small positive offset without affecting steering. Choose thick and sturdy spokes to reduce damage from sand and gravel impact, and choose dirt resistant black or gun gray colors.

 

 

The core demand for new energy vehicles is "low rolling resistance+lightweight" to extend the range. It is recommended to follow the original factory specifications of 17-19 inches to avoid affecting power tuning; Factory supplied low wind resistance forged wheels adopt aerodynamic design to reduce energy consumption and noise, which is the preferred choice. Choose ET40-50 for offset to ensure compatibility with the suspension, choose a style with strong closure for the spokes to reduce wind resistance and protect the brake system, and match the technology oriented positioning with light or contrasting color designs.

 

 

For forged wheel selecting, three key points should be noted: first, confirm that the parameters such as hole spacing (PCD) and center hole (CB) are consistent with the original vehicle to avoid installation hazards; The second is to select materials according to the scene, with emphasis on off-road strength and commuting weight; Thirdly, we should not blindly pursue larger sizes and prioritize ensuring stability. At the same time, it is necessary to choose products from reputable manufacturers and check the testing reports to ensure safety. 

 

Choosing forged wheels for different car models is essentially about "precise matching of needs". Sedans prioritize comfort, SUV prioritize strength, supercar prioritize performance, and new energy vehicles prioritize endurance. Only by clearly defining core requirements and parameters, and then selecting styles based on aesthetic considerations, can the wheels enhance both aesthetics and practicality.

1. Heat transfer printing head

The Heat transfer printing head is mainly composed of a surface film protective layer, a bottom film protective layer and a heating element. The heating element is a conductive silk screen. With the help of the heat generated by the voltage pulse, the coarse particles of the ink layer in the graphic part are raised and melted to complete the ink transfer by thermal diffusion.

The printing speed of heat transfer depends on the time required for each line of graphics. Therefore, the transfer head and the transfer paper should have good heat transfer properties, so that the heat generated by the heating element can quickly pass through the protective layer, the transfer paper substrate and the gap and finally transfer to the surface of the substrate to ensure that the ink has sufficient transfer time.

2. Ink

The composition of heat transfer ink is generally three parts: pigment (pigment or dye), wax and oil. Among them, wax is the main component of heat transfer ink.

During printing, the viscosity of different inks has a direct relationship with the heating temperature, and the heating temperature and the viscosity of the ink should be strictly controlled. Practice has proved that when the heating temperature is 60-100 ℃, when the ink is melted, the viscosity value of the ink is stable at about 0.6pa·s, which is the most ideal. Generally speaking, the closer the ink is to this state, the better the transfer performance.

3. Transfer medium

Chemical properties: Making the ink adhere well and evenly is two important performances of the chemical properties of the transfer paper substrate. The chemical properties of transfer paper in production directly affect the quality of printing.

Good thermal performance: Since the transfer process is achieved by means of high temperature, the material of the transfer paper must be able to withstand the influence of the transfer temperature and keep the properties unchanged.

4. Substrates

Experience has shown that substrates with a slightly rough surface produce better quality prints, which is a characteristic of heat transfer printing. Because the rough surface of the substrate indicates that the substrate has a large surface energy, the ink on the transfer paper can be transferred to the substrate well, and the ideal level and tone can be obtained, but too rough will affect the normal operation of the ink. Transfer is not conducive to the realization of the printing process.

guide rail, the printing plate and the working platform plays important role.

The adjustment of the parallelism between the three layers of the guide rail, the printing plate and the working platform: generally the guide rail or the platform is used as the reference for the adjustment. 1The platform and the guide rail should be parallel, and the squeegee plate moves along the guide rail. If the two are not parallel, the squeegee will not always touch the platform with a certain pressure, and even the gap will occur. This adjustment has been adjusted before the machine leaves the factory. 

 

 

 The screen printing plate and the platform should be parallel, otherwise the mesh distance (distance from the bottom surface of the screen printing plate to the printing surface) is inconsistent, causing the printing pressure and the screen printing plate to be inconsistent. Therefore, the flatness of the frame itself should be guaranteed. 

 

 

Adjustment to the plate: refers to the adjustment of the printing precision between the screen printing plate and the printed object on the screen printing machine.

 

Squeegee adjustment: 1 Adjusting the parallelism of the screen by the squeegee, adjusting the left and right screw to adjust the height of the ink plate; the left and right sides of the middle shaft can be adjusted with the top wire to adjust the left and right top wires, and the height is adjusted to the right and left of the ink plate respectively. 2 The adjustment amount of the blade inclination angle is generally in the range of 65 to 85 , and can be selected as needed. 3 The adjustment of the printing pressure is actually the adjustment of the position of the squeegee. 4 The length of the squeegee can not be adjusted, generally supplied as a kit, each set has several different lengths to choose from. Stroke adjustment: including adjustment of stroke size and stroke position. Through the adjustment of the crank and the radius R of the swing rod, the stroke adjustment is realized, and the R increase stroke is increased, and the stroke length generally exceeds the pattern of 20 to 50 mm. Network (table) distance adjustment: the net (table) distance adjustment can be realized by reducing the screen printing plate or raising the platform, generally adopting the method of raising the platform. The screen plate four-corner net table spacing should be consistent, the error is 0.5mm. The distance between the nets is generally 2 to 5 mm, and the net is allowed to be smaller from the front and the rear only 

The screen printing of the equipment shell panel is also a kind of screen printing. It is mainly used on equipment and machines. With the continuous progress and completeness of modern technology, this kind of panel screen printing is becoming more and more widespread. For example, the panel printing and decoration processing of electrical equipment.

The silk screen panel is an operation panel printed through the silk screen printing process, which is widely used in various industrial products, electrical appliances and other panel decorations that require identification and marking. It is widely used in equipment housing, electronic processing industry, printed circuit board silk screen logo, instrument housing panel logo, solder paste printing during circuit board processing, etc. There are also large-scale carton boxes that are printed using silk screen printing. Mainly include text screen printing, LOGO screen printing, various color screen printing and so on.
