Many people think that as long as the wheel hub is bigger, it must be better, after all, it is certain to look good. But there are often disadvantages. The disadvantages will be discussed in a while, let’s talk about how to choose the hub and what craft to choose. At present, there are three mainstream process hubs on the market, low pressure casting, flow forming wheel and forged wheel. This is most of the crafts on the market at present, and it is not ruled out that there are small workshops and gravity wheels. Let's talk about the differences and craftsmanship of these types of wheels. Low pressure casting wheels Low pressure casting is well understood. It is to set the mold, and then pour the molten aluminum into the mold, and then apply a certain pressure to make the internal molecules more compact. This is low pressure casting. is to use this wheel. Because of the high cost performance and good production, the price is also cheap and affordable. Flow forming wheels Spinning is actually more complicated processes on low-pressure casting, and they are all produced by low-pressure casting, but the part of the rim is heated and rotated and stamped by a spinning machine, so that the molecular density of the rim part can be improved. Corresponding rims are more rigid, so many car owners have chosen spinning wheels. Of course, it should be too expensive for forging. Spinning takes an intermediate value between casting and forging, which has both cost-effectiveness and performance. The current price of spinning wheels Also somewhere in between. Likewise, the spun hubs are made of the same A356 casting aluminum as the low pressure cast. Forged Wheels The forged wheel is different from the aluminum used in the above two. It uses 6061 forged aluminum. The rigidity is like the difference between the iPhone 6 and the iPhone 6S in previous years. One is bent. The forged wheel not only occupies the aluminum and rigidity Advantages and weight are also the reasons why many people choose. Lightweight means lower fuel consumption and better control of the body. The most important thing is that forging supports customization. You can do whatever you like. The engineer draws the drawings according to the requirements, and then mills them on the forged aluminum blank. The first two are not supported. After all, no manufacturer will reopen the mold. This is why forging is expensive.

In many unexpected times, there will be unexpected situations in the finishedrim, which will make the finished defective. At this time, we need to repair the wheels. Most of the wheels on the market are electroplated, so the maintenance of thechromed wheels and the precautions for the maintenance of the wheels are easy to share for you. When repairing arim, the first thing to do is to determine whether it is anchromedrim. If not, repairs in the electroplating plant are meaningless. If there is no plating, it should be painted. Chromed wheels can also be divided into silver plating, water plating and pure plating. Among them, pure chromed wheels have a long service life and good quality. Most middle and high-end automobiles use pure chromed wheels. When repairing or upgrading, we should pay attention to the following points: Rim deviation, PCD value and hole position, and the size and shape of therim are basically the places that cause problems, so you should pay attention.

Once you have made a wheel sale, test-fitted the wheels, and mounted and balanced the tires, you must do one final thing--attach the wheels to the car. Although often overlooked, the hardware associated with wheels is vital to getting a good installation. The most obvious piece of hardware is the lug nuts used to secure the wheel to the car. In most cases, either for appearance sake or functionality, you won't use the stock lug nuts to attach the wheels. Lug nuts come in three broad categories: acorn, mag and tuner style. Within each category, there are a number of variations. Some European cars use a fourth type--a lug bolt which screws into the vehicle. A typical catalog shows nine acorn styles, three mag styles and five tuner styles. Fortunately, the wheel catalog will usually tell you which type of lug nuts to use with the wheel you are buying and of the 17 styles mentioned above, a few are pretty rare. It's a good idea to have the more common styles in stock to prevent any delays when installing wheels. Acorn styles are the most common and they are available in either open end design, which are used when the lug nuts are covered by the wheel's center cap, or closed end type, which are used when the lug nuts are exposed. Closed end designs come in various lengths, the longer ones normally used on trucks where extra length is needed. Mag styles are the least common, used mainly on older style wheels. Mag lug nuts must be used with washers. Tuner style lug nuts are used where there is very little room in the lug nut opening. This is especially common on small, front wheel drive cars known as "tuners." That's where the name comes from. They come with a "key," which either fits into a cut out in the center of the lug nut or goes over the lug nut itself. Without the key, you can't remove the lug nut, so make sure you give this to your customer.

When shopping for nuts make sure they match the thread diameter, pitch and seat of the ones you are replacing. If these aren't the right fit, the new nut may hurt your expensive wheels. They can also ruin the mounting lugs for your vehicle, which is not a cheap proposition. And then there's the fact that improperly secured wheels make your car a potential hazard on the road. The three basic types of nuts are: conical seat (60 degrees taper "acorn" and "bulge"), mag or shank style, and spherical or ball seat. Thread diameter refers to the diameter of the stud measured across the shank at the outer edges of the threads. Thread-pitch means either the number of threads per inch or if metric, the distance in millimeters between threads. The seat means the area on the wheel where the nut will clamp down. Manufacturers only recommend one wheel lock lug nut per wheel to keep your wheels from being stolen. The wheel lock lug nuts come with a special tool that you attach to your wrench so that only you can unlock your wheels. Custom lug nuts can have special chrome plating so they are resistant to rust and normal wear and tear. This kind of nut also comes in different color caps so that they match the color of your custom wheels. After all, if you've invested in both custom wheels and nuts, you want them to look good together. This very small investment can add value and protection to your wheels. It seems like a logical choice when you are going to the trouble to upgrade this part of your vehicle.

Wheel adapters are widely used in the industrial process. They are usually found in the situations which require a fitting to help to put a wheel on a vehicle. Dating back to the very beginning, the wide bolt pattern has made impossible decorative rims. As a result, this fitting are designed to bring in many benefits. When the wheel is not normally required to be placed on a vehicle, it is wise to take the wheel adapter for help. The corn parts of this fitting are the two bolt patterns. The one is used to attach the vehicle's hub and the other is used to protrude from the adapter. As the space has been left, the new required wheel can match the vehicle conveniently and perfectly. The wheel adapter is able to excellently combine the vehicle and the wheel together by the aid of the special countersunk lug bolts and nuts. Generally speaking, the materials such as the aluminum or steel are available for manufacturing of this necessary industrial fitting for most automobiles. And in order to meet the various specifications, there is a great variety for practical use. For example, the most common type is the one designed like a heavy and flat disk. It can be attached tightly by the pre-drilling studs and others to the onside holes. People would wonder the safety caused by the employment of the wheel adapter . Actually, it is safe seriously under the related specifications. If the weight and size limits or other things can be totally under control, it is beneficial by adopting the wheel adapter. But there is something which needs our attentions. As this fitting is designed primarily for decorative retrofitting of aftermarket wheel, it is unwise to put it for the use of heavy hauling or hard cornering.

Alloy Wheels perform the same function in automobiles as the normal steel ones but they have certain added features that make them different and arguably better. Compared to wheels made of steel, alloy wheels are composed of aluminum or magnesium alloys making them stronger and durable, lighter in weight, better in performance and most importantly, stylish. These wheels are manufactured either by the process of casting or by forging of metal alloys. Forged alloy wheels are lighter and much more durable than cast alloys but they are a little hard on the pocket. These wheels are usually the preferred choice for high-performance sports cars but that does not mean you can't fit them on any other car. Comparatively, cast aluminum alloys are heavier but they are cheaper and yet have almost the same styling as that of forged alloys. There is however another type of stylish wheels called Mag-Wheels. Magnesium alloys or mag-wheels are whole magnesium cast or forged wheels used in racing cars as they are the lightest wheels available. Mag-wheels are high on performance as well as on styling. Unmatched style is probably the main reason why most people now prefer alloy wheels for their vehicle. There is no doubt that alloys make the vehicle look posh and increase its cosmetic appeal but there are two other definite advantages of fitting them in your car instead of the normal steel wheels: Alloy wheels are lighter, that means your vehicle has less unsprung mass. This means your vehicle handles better and there is improved road grip on most terrains. A lighter vehicle will obviously perform better on the mileage count as well. They are also good in terms of balancing. Your vehicle balances well reducing stress on other parts of your car like the suspension and the axles.

Keeping your vehicle takes time, money and patience; however it is completely worth it in the end. There are so many different parts of your vehicle to clean, car for and protect. One part of your vehicle that is very important to care for is your vehicles wheel rims. If your wheel rims are not in good condition not only do they not look good but can be very expensive to replace. Find out ways that you can care for and prevent damage to your wheel rims. It is definitely worth the time and money to find out! At first, start out by taking care of your wheel rims . Since most of don't have the extra cash flow right now for new ones the easiest way to get them looking and staying nice is to take care of them. You need to make sure that you wash your wheel rims on a regular basis. If you take your car to the car wash instead of hand washing it, you wheel rims are probably not getting their cleanest. Unfortunately that is an area of your vehicle that doesn't really benefit from the car wash. It just takes soap, water and a cloth or brush. You need to make sure that you can reach all the little areas of your wheel rims with whatever tool you choose. You should also dry them when you are done washing and rinsing. Also if you spray a tire shine product on your tires that can leave a residue on your wheel rims. Make sure that you clean that residue off when you are done. Next,simply try to avoid situations that may lead to wheel rim damage. This is best way to save yourself money. Sometimes it will involve more time and patience on your part but it will definitely be worth it. First of all try not to take the corners to close while driving. What happens is that you take it too close and your wheel rims scrap the curb and you are left with scratched and maybe even dented wheel rims. Also be sure that you avoid potholes in the road. If you hit a pothole in the road you may be left with damaged wheel rims as well.

Forging is the process of shaping metal, and is a common practice in a range of manufacturing industries. There are various types of forging, and these are often distinguished by the temperature at which it is conducted. The 3 independent classifications are cold, warm and hot, with the most popular types of metal including iron and steel almost universally forged hot. The process has many advantages and also some disadvantages to the companies that use it. The Benefits of Forging Forging is almost entirely beneficial process from the point of view of those who use the finished product. The process of forging often produces a piece of metal that is far stronger than a piece that has been fortified by a machine part or cast. In terms of metals such as steel and iron, which are the most commonly utilized materials within the construction industry, this strength and durability is key to their appeal and the tasks that they perform. The grain of the metal is also fortified by the process of forging, allowing it to remain continuous through the part as it is worked upon. As it is shaped, the grain melds to the specific outline of the part, which only increases the strength of the material and the actual metal part. These facets of forging at heat ensure that it remains especially popular when it comes to shaping steel and iron, and guarantee a high quality product for the receiver. The Shortages of Forging In terms of hot forging, there can be issues for parts which are required to go through a secondary mechanical process afterwards. For any secondary process that needs to be carried out after a metal item has been forged, it must have undergone the work hardening process that would ensure from cold forging. Hot forging can prevent this, although in many cases there are more economic and easy to control alternatives to work hardening anyway. In any case some forgings, such as aluminum alloy pieces and titanium, can be work hardened after hot forging so the issue is not an overly significant one. The only considerable drawback to forging are the costs involved in paying for machinery and tooling.

In the wheel industry, there are two main types of wheels: 3 piece forged andcasting. There are many advantages to each type as well as disadvantages. The main difference betweenthem is the manufacturing processes used to create them. In the forging process, 3 piece wheels begin as high-quality T6-6061 aluminum alloy billets. The billets are then subjected to intense pressure to form the shape of a wheel. Due to the great amounts of pressure, tiny imperfections, holes, and cracks that can form during manufacturing are eliminated, creating a dense grain structure. The process of manufacturing a forged wheel also uses less metal to achieve a desired strength, thus reducing weight, which can improve overall vehicle performance. A forged 3 piece wheel also uses a number of different parts. The wheel is made up of a center, outer barrel, and inner barrel. Both the inner and outer barrens are sealed together and then fasted with the face by a number of bolts. This construction allows for manufacturers to provide different wheel widths and offsets. Casting wheels use a different manufacturing process than forged wheels. There are two types ofcasting: gravity and negative pressure. In gravitycasting, molten alloy is poured into a mold in the shape of a wheel where it then cools. With negative pressurecasting a vacuum sucks the molten material into a mold, reducing the number of air pockets in the wheel. Bothcasting processes are both less expensive and quicker than forging. However,casting wheels are not without their faults. Tiny imperfections can still remain in the wheel after it cools which can lead to cracking, quality, and reliability issues. The process also requires more material be used to achieve a given strength, thereforecasting wheels are usually heavier than forged 3 piece wheels. Forged 3 piece wheels offer owners up to a 35 percent reduction in weight over similarcasting wheels due to their construction. While forged wheels may be more expensive thancasting, the high-strength and quality properties ensure that a forged 3 piece wheel will be more reliable and durable.

The metal forming processes of aluminum-alloy wheel forging at elevated temperatures are analyzed by the finite element method. A coupled thermo-mechanical model for the analysis of plastic deformation and heat transfer is adapted in the finite element formulation. In order to consider the strain-rate effects on material properties and the flow stress dependence on temperatures, the rigid visco-plasticity is applied to the simulation. Several process conditions were applied to the simulation such as punch speed, rim thickness, and the depth of die cavity. Experiment for a simplified small-scale model is carried out and compared with the simulation in terms of forging load to verify the validity of the formulation adapted in this study. Then, various processes with full-scale model for a 6061 aluminum-alloy wheel are simulated. Material flow, pressure distributions exerted on the die wall, temperature distributions and forging loads are summarized as basic data for process design and selection of a proper press equipment. All of our wheel rims are forged using 1000T forging machine. The production process of forged wheel rim: aluminum bar 6061,forging,blank treartment, light blank, molding, dynamic balance test, polishing, finishing treatment, checking and testing, packing. We handle every process with our heart to guarantee our high quality and supply more safer wheel to our customers.

Aluminum alloy material is not only lighter than iron, but also harder than iron, so it is perfect for wheel rims. But aluminum alloy is metal after all. High school physics knowledge tells us that metal has ductility, so aluminum alloy wheels will also be out of round. In addition, the high hardness of aluminum alloy makes it difficult to repair by hammering, so it can only be repaired by turning. Turning the wheel rim will make the wheel rim thinner, unable to withstand strong impact, and it is easy to break when encountering potholes, which is a safety hazard. There is a relatively mature technology for repairing the out-of-roundness of aluminum alloy tires in foreign countries. They use heating to put the wheel back into the mold to restore it, but at present, it is known that such technology has not been introduced in China. Therefore, whether it is an iron wheel or an aluminum alloy wheel , if it is out of round, it is not recommended to repair it, because there will still be safety hazards after repair.
