Laurell Technologies WS-400 spin coater used to apply photoresist to the surface of a silicon wafer. Spin coating is a procedure used to deposit uniform thin films onto flat substrates. Usually a small amount of coating material in liquid form is applied on the center of the substrate, which is either spinning at low speed or not spinning at all.
Spin casting is a favored method for fabricating items in the specified materials – low temperature metals and thermoset plastics. Compared to the two main competing processes, injection molding and (zinc) die-casting, spin casting has significant advantages in terms of startup cost and ease of use.
However, the wheelset does not need to lock up completely in order for damage to be caused. If the slide is significant, heat can build up in the contact patch between the wheel and the rail, sufficiently to permanently modify the crystalline structure of the wheel's steel alloy.
The precursor sol can be either deposited on a substrate to form a film (e.g., by dip-coating or spin coating), cast into a suitable container with the desired shape (e.g., to obtain monolithic ceramics, glasses, fibers, membranes, aerogels), or used to synthesize powders (e.g., microspheres, nanospheres).

With the larger alloy wheels came Tru-Spinner Wheels and spinner wheel add-on spinners that would free-spin and continue to free-spin after the alloy wheel itself came to rest. American inventor James JD Gragg of International and American Tru-Spinners were the original ones and were leaders in the industry.

Thinner coatings may cost less but can chip and crack. Thicker coatings will alter the shape and size of the truck bed somewhat. For trucks with the most rugged use, Armor Thane sets an optimum thickness for bed liners as 1/4 inch on the bed and wheel wells and 1/8 inch on the sides. Truck bedliner applied with a spray-on technique
