THE BBS DESIGN PROCESS

3D Computer Modeling Computer Simulation
Once the initial design sketches have been developed, a graphical three-dimensional model of the new BBS light alloy wheel is created. By using the latest technologies, the initial creative idea is turned into what will become the basis for the future wheel production. One of the main advantages of the computer model is that numerous simulation programs can be used to thoroughly test the wheel right from its very beginnings. Once the basic design has been constructed on the computer, every detail of the development process can then be simulated and changed on screen. Thanks to the latest 3D technology, developers can view a photo-realistic model of the wheel they're producing. They are also able to adjust the model to view slight changes in proportions or the two-colour paintwork. Once all of the design features have been decided upon, the model is transferred to the CAD system to move one step closer to a live prototype.


Design Sketches Final Design
Behind every new BBS light alloy wheel lies a great idea. Using the first set of design sketches, designers are able to develop the product characteristics that will make each wheel an individual masterpiece whilst also incorporating typical BBS design values. One of these design values is the characteristic BBS cross spoke that can be found adding sporting dynamics on roads all across the world in its many variations. When developing a new wheel, once the first prototype has been built and initially tested, it's time to start the construction optimisation phase. During this phase, it may be necessary to adjust, remodel or even discard the wheel design. However, one thing is guaranteed when already developing the initial sketches for a new BBS light alloy wheel: at the end of all the tests, simulations and prototypes there will be a new product and a final design.


THE BBS PRODUCTION PROCESS

Low-Pressure Casting Flow Forming
The best foundation for a perfect and long-lasting product is a top-quality casting blank. To achieve this, BBS uses low-pressure aluminium casting technology. The aluminium alloys are compressed in a multi-part mould using a pressure of 2 bar. After cooling to around 400 degrees Celsius, the mould is opened and the finished casting blank is moved along a conveyor belt to its first material check. Low-pressure aluminium casting is an extremely sophisticated technology that demands exceptional knowledge and skill from their employees. Less is more when flow forming is used to increase the density of the light alloy wheels' material structure. This is achieved by continuously rolling the rim well over a cylinder under high pressure and at a high temperature, from 300 to 350 degrees Celsius, so that it is remodelled. The outcome is a thinner rim wall thickness and a lighter wheel that needs less material to be more resilient.


Forging Technology Dry Processing
A forged wheel is made by forming its shape when it is warm and solid. To get maximum material density and weight reductions out of our highly rigid and durable aluminium alloys without forgoing top performance, they undergo an elaborate forging process. The heated centre of the rim or the entire rim well is compressed during several stages in a forging press under 5,000 to 8,000 tons of pressure to densify the material into its special form. Between the individual stages, the rim is repeatedly heated up to around 400 degrees Celsius. The result is a much stronger and lighter wheel that is able to handle very high levels of mechanical strain on the road. Where possible, BBS treats the surface of all its wheel types using a dry processing method. Dry processing is a prize-winning, special processing method developed by BBS. The wheel is put through a CNC rotary milling machine and is dry processed using only an air and oil mix. Aerosols are then used for cooling. By applying this technique, it is possible to avoid the problematic use of oil and water coolant as the disposal of this coolant is both expensive and complicated. Another advantage of using the dry processing method is that all filings can be fed straight back into the material cycle without any problems.


Processing Coating
To attain the highest level of production possible, each light alloy wheel is processed by both machine and hand. For example, after casting, all wheel types are manually deburred and excessive material is removed so that the wheel is in best condition possible when it moves on to the next processing steps. There is a lot more to the coating process than simply powder coating. Lacquering, both clear lacquer and the application of opaque colours, is a liquid form of coating. All types of coating used by BBS fulfil a practical use as well as enhancing the wheel's aesthetics. By adding additional surface layers to our light alloy wheels, we are able to better seal the surface in order to provide increased erosion protection and optimum maintenance. The perfect basis for long-lasting driving pleasure.


Finish Surfaces
At the end of the production process, each of their wheels reaches the finishing stage. At BBS, finishing is more than merely making something look good. The final surface finish we apply to our wheels is first and foremost about improving the material. Coating or ball-polishing a wheel or attaching a rim protector extends the lifespan of a BBS light alloy wheel. For example, ball polishing densifies the aluminium alloy of the wheel and makes it even more resilient. A final layer of clear varnish then protects the surface in the long term. In the case of their coated wheels, we achieve the same effect with the help of a multistage coating process using extremely impact-resistant and robust water-based coatings. BBS pays special attention to the surface of every light alloy wheel and its unique composition. This is because a flawlessly treated surface offers maximum protection against corrosion, dirt and other elements. All of their wheels' surfaces are automatically and repeatedly sealed to ensure an optimum surface structure and a protective finish. As they pride themselves on leaving no room for error, even the smallest imprecision is not tolerated and if the wheels do not match their highest quality standards, they are immediately removed from the production process and re-moulded.
