00:00This wheel spacer didn't start out looking anything like this.
00:02It began as a piece of aluminum, then went through forging, heat treatment, precision machining,
00:08and surface finishing before it was ready to be installed on this 2021 Jeep Wrangler JL.
00:14But what actually happens at each stage, and why does the manufacturing process matter?
00:18Let's follow the process from raw material to the finished part.
00:22The process starts with aluminum alloy selected for the intended application.
00:27For this product, we're looking at AL6061T6.
00:31Before the material becomes a wheel spacer, the stock is cut into the required starting pieces.
00:37Consistent preparation helps establish the starting dimensions for the following manufacturing stages.
00:43Next comes forging.
00:44The aluminum blank is heated according to the manufacturing process
00:48and pressed into a shaped form using specialized tooling.
00:52Unlike machining the entire part from a solid block,
00:55forging changes the material's shape through controlled deformation.
00:59The goal is to create a suitable starting form for the component.
01:03While the final properties still depend on the alloy, forging process, subsequent heat treatment,
01:08and the design of the finished part.
01:10At this stage, the part is not finished.
01:13It still needs further processing to reach its final dimensions and features.
01:18After forging, excess material is trimmed away, and the blank moves into the next stage of preparation.
01:24The part may then undergo preliminary machining or drilling to create reference features for later operations.
01:31These steps prepare the component for more precise work.
01:34At this point, the focus is on establishing the shape and surfaces that the CNC machines will refine.
01:41Next is heat treatment.
01:42The T6 condition involves solution heat treatment followed by quenching and artificial aging,
01:48according to the applicable process specification.
01:51This stage is important because the alloy's final mechanical properties depend on its heat treatment condition,
01:57not simply on the fact that it has been forged.
02:00Now we get to one of the most precise stages, CNC machining.
02:04The component is machined to establish the mounting surfaces, center bore, bolt pattern,
02:10and other dimensions required by the application.
02:13Different operations handle different features.
02:15Turning establishes the main surfaces and diameters.
02:19Drilling creates the required holes.
02:21Additional milling operations form specific features in the design.
02:25For a hub-centric wheel spacer, the relevant dimensions need to match the intended hub and wheel interface.
02:32This is where the part's actual geometry is refined.
02:35A component can look finished at a glance, but the mounting surfaces and critical dimensions still need to meet the
02:42required specifications.
02:44After machining, the component moves to surface finishing.
02:47For this product, the finishing process includes surface preparation,
02:52cleaning, anodizing, and the applicable sealing and finishing steps.
02:56Hard anodizing forms an oxide layer on the aluminum surface.
03:00Depending on the process specification, it can improve surface hardness and wear resistance.
03:05The final result depends on the alloy, surface preparation, process parameters, and quality control.
03:12Now we can see the details of the finished Banas forged active cooling wheel spacer.
03:17The hub-centric interface is designed for the specified application.
03:21The multi-stage rear profile, mounting features, and cooling grooves are all part of the component's geometry.
03:28The active cooling grooves are designed to guide airflow as the assembly rotates.
03:32After inspection, the spacer is prepared for packaging and shipment.
03:37Here is the finished spacer installed on our 2021 Jeep Wrangler JL.
03:42Before installation, the fitment must be confirmed for the specific vehicle and wheel combination.
03:48The mounting surfaces, hardware, stud clearance, and required tightening specifications all need to be checked.
03:55From raw aluminum to a finished Jeep Wrangler installation, every stage has a different job.
04:00Forming the material, developing its mechanical properties, creating precise geometry, finishing the surface, and checking the final component.
