Forging is a processing method that uses forging machinery to apply pressure to metal blanks to produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Through forging, it can eliminate the defects such as loose as-cast produced in the metal smelting process and optimize the microstructure.

At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. For the important parts of related machinery with high load and severe working conditions, forgings are mostly used in addition to simpler shapes that can be rolled, profiles or welded parts.

The technological characteristics of forged wheels are roughly as follows:

1. The cylindrical design is adopted. The larger the diameter of the rim is, the thicker aluminum material is used for forging, which is completely different from the manufacturing method of using "raw materials" for cast aluminum rims;

2. Cut the aluminum material according to the J number required for the width of the aluminum ring;

3. First heat the aluminum ingot to around 400 degrees Celsius, then it is ready for forging;

4. Hot forging and pressing, the higher the tonnage of the forging press requires the lower the working temperature of the aluminum ingot, the smaller the grain of the forged product, and the higher the toughness;

5. The temperature of the rough embryo formed by high temperature and high pressure is very high, and the surface is covered with black carbides, which must be handled by a fork motive. The rough embryo after pickling surface treatment already has the embryonic shape of a wheel hub;

6. After long-term reprocessing and heat treatment of the T4 and T6 heat treatment machines, the grains of the rough embryo will be firmer and the toughness of the product will also be improved;

7. Forged aluminum ring must rely on mechanical processing to process the rough embryo to the rim forming, so the work content includes bead forming, screw hole drilling, disk turning, detail processing and other steps;

8. Before painting, you must check the rim surface for flaws.

FAQ

Q1:What information should you provide for a quotation?
A:At first,tell me what wheel structure,one piece ,two piece or three piece.Usually we need know your car 's model and what wheel diameter you want or your tire size, color, the others (ET,PCD,CAP style,..), or we can provide some reference size.

Q2:How do your custom and confirm your wheel styling?
A:you can choose our style or provide your own satisfactory styling pictures, we design and send you to confirm, and modify, modify, still you feel satisfaction.

Q3:When can I get the price?
A: Usually we have a standard price, and we will send you the quotation within 4 hours after you confirm style and your want colur.
Q4:How about your delivery time?
A:Generally, it will take 15 days for one-piece and 20 days for two-piece and 30 days for three-piece after receiving your advance payment.

Q5:How do you guarantee the quality?
A:We do all detection(size ,roundness,surface quality) to guarantee every wheel high quality.
Q6:Do you accept OEM or ODM order?
A:We accept OEM, ODM with customer's logo and packing design.
Q7:What's your min. order?
A:four piece.
Q8:How about the payment?
A:We suggest you place order by Alibaba Trade Assurance, it minimizes risk by guaranteeing money back in the event of a supplier failing to meet the terms of the order contract - including delivery delays, quality and quantity discrepancies or other processing problems.
