Employees are stationed at different parts of the conveyor, some loading the hooks with your rims and other unloading them.
You won't need to do much in terms of cleaning for powder-coated metals. The curing process allows the powder to create chemical bonds that make it last a long time.

Use a respirator, gloves, and eye protection when abrasive blasting metal to remove scale. Measurement results are displayed on an easy-to-read liquid crystal display (LCD). But if you do order it yourself we can still do the job. To a powder coating operation, this means software, data, and processors reside on a trusted service provider's servers. Some instruments can even produce rudimentary analysis during measurement by separating jobs or parts into batch memory and displaying real-time average thickness results and min/max limits. It's also dangerous to do this inside of the kitchen due to the fumes it produces while curing. The coating will adhere any bolts making it impossible to remove unless the part is stripped of its paint again. Infrared (IR) ovens, using either gas or electricity as their energy source, emit radiation in the IR wavelength band.
