The cleaned fragments enter a continuous carbonization furnace where they're heated in an oxygen-free environment. Through thermal decomposition at controlled temperatures, the paint layers soften and break down into gas and carbon black, separating cleanly from the aluminum base. The furnace's rotating design ensures even heat distribution throughout the process.

After carbonization, the aluminum material goes through cooling and mechanical processing to remove any remaining carbon residues. The final output is pure aluminum ready for smelting. Notably, the combustible gases generated during pyrolysis are captured and reused to power the equipment, creating an energy-efficient closed-loop system.

​Key Advantages of the Process​
The automated continuous operation allows for 24/7 processing with daily capacity reaching tens of tons—significantly outperforming traditional chemical paint removal methods. The system achieves over 98% paint removal efficiency with minimal human intervention.

From an environmental perspective, the process eliminates the need for harsh chemicals, preventing contamination from acid or alkaline wastewater. Emissions are effectively treated through purification systems like activated carbon adsorption, meeting stringent air pollution standards.

The economic benefits are equally impressive. The resulting aluminum boasts higher purity levels, achieving recovery rates exceeding 95% when converted to recycled aluminum ingots. This creates substantial economic value while supporting circular economy goals.

​Market Outlook and Applications​
Growing environmental regulations, including China's Solid Waste Pollution Prevention Law, are driving adoption of cleaner technologies like carbonization. The process's environmentally friendly characteristics facilitate compliance with environmental impact assessment requirements.

The technology also enables complete resource utilization. By-products such as carbon black can be repurposed as rubber fillers or soil conditioners, creating additional value streams while minimizing waste.

This advanced approach to can recycling represents a significant step toward sustainable manufacturing. By transforming waste into high-quality materials, it demonstrates how technological innovation can drive both environmental protection and economic growth.

Imagine an assembly line for cleaning metal. That's essentially what a continuous decoating furnace is. Unlike batch processes, it operates non-stop, feeding metal parts through different zones for heating, processing, and cooling.

This continuous workflow translates to vastly higher throughput. Whether the items have thin or thick paint layers, the furnace parameters—like temperature and processing speed—can be easily adjusted to achieve a perfect, clean strip. This flexibility makes it ideal for handling a wide variety of metal parts efficiently, saving significant time and labor.

​2. A Clear Win for Safety and the Environment​

This is perhaps the most significant advantage. Chemical paint strippers often contain harsh, toxic substances that pose risks to worker health and the environment. Safe handling requires strict protective measures, and the disposal of used chemicals creates hazardous waste.

The decoating furnace eliminates this problem entirely. It uses high temperatures in a controlled, oxygen-free environment to break down paint into gas and a small amount of solid residue. It's a purely physical process—no toxic chemicals are needed. This means no dangerous fumes for workers, no risk of chemical spills, and no toxic wastewater to treat. It’s a much cleaner and safer solution for everyone.

​

3. Simple Operation and Easy Maintenance​

Managing chemical strippers is complex. It requires careful monitoring, storage, and handling procedures to prevent accidents. In contrast, continuous decoating furnaces are designed for simplicity. Modern units are equipped with automated control systems that manage the entire process—temperature, conveyor speed, and atmosphere are all precisely controlled from a panel.

This automation reduces the potential for human error and minimizes the need for specialized operator intervention. Maintenance is also straightforward, typically involving regular inspections and basic servicing to ensure long-term, reliable performance.

​4. Handles Almost Any Metal Part​

Versatility is a major strength. These furnaces can be adapted to process metal parts of various shapes and sizes, from small components to large structural pieces.

Selecting an industrial tire shredder is a major investment that forms the foundation of a profitable recycling operation. The right machine can bring long-term success, while the wrong choice may lead to constant downtime and high maintenance costs. This guide simplifies the decision-making process by breaking it down into seven key factors you should consider.

​1. Processing Capacity (Throughput)​​
Start by evaluating your actual needs. How many tons of tires do you need to process per hour? Be realistic about your current volume and allow for future growth. A small operation might start with a machine handling 2 tons per hour, while larger facilities may require equipment capable of processing 15-20 tons per hour. Choose a supplier that offers multiple models to match your specific needs without paying for unnecessary capacity.

​2. Tire Types and Feed Size​
Not all tires are the same. Are you processing passenger car tires (typically under 900mm) or larger truck tires (up to 1200mm)? The shredder's feed opening must be large enough to handle your largest tires without pre-cutting. A versatile industrial tire shredder should handle both car and truck tires with ease.

​3. Required Output Size​
Your final product determines your profit. The size of the rubber chips is determined by the blade width. Most TDF (Tire Derived Fuel) buyers require chips between 50mm and 100mm. Confirm the exact specifications with your buyers beforehand. Reputable equipment manufacturers can configure their machines to produce specific sizes within this range, ensuring your output meets market requirements.

​4. Power and Motor Quality​
The motor is the heart of your shredder. While power (kW) is crucial, it must match the machine's capacity. A 2-ton per hour machine might need about 65 kW, while a 15-ton per hour unit could require over 300 kW. More importantly, inquire about the motor brand. Reliable motors from established brands ensure better performance, higher efficiency, and longer service life, reducing the risk of unexpected breakdowns.

​5. Blade Material and Design​
Blades represent the core of your shredder and your main operating cost. Don't compromise on blade quality. Ask specific questions about the material composition. Are they made from basic steel or more durable alloy steel? High-quality alloy blades offer better wear resistance, staying sharper longer and requiring less frequent replacements. Also consider blade thickness - thicker blades (50mm to 100mm) generally provide more strength for heavy-duty applications.

​6. True Budget (Total Cost)​​
Look beyond the initial price tag. A cheaper machine may cost more in the long run. Consider the Total Cost of Ownership (TCO), which includes the purchase price, energy consumption, maintenance costs (blade replacement, lubrication), and the machine's weight (which often reflects steel content and build quality). A heavier machine typically offers better stability and durability. An efficient, reliable industrial tire shredder may have a higher upfront cost but can save you money over its lifespan.

​7. After-Sales Service and Support​
When your machine stops, your business stops. Does the manufacturer offer good support? Ask these crucial questions: How long is the warranty? Are spare parts (especially blades) readily available? Is technical support available when problems occur? Choose a partner, not just a supplier. Good support is essential for critical industrial equipment.

By carefully considering these seven factors, you can make an informed decision that will serve your business for years to come. Remember that the cheapest option is rarely the most economical when viewed from a long-term perspective.

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.

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.
