Curing is a term in polymer chemistry and process engineering that refers to the toughening or hardening of a polymer material by cross-linking of polymer chains, brought about by electron beams, heat or chemical additives.esin curing [edit]. Despite the wide variety of thermoset resin formulations (epoxy, vinylester, polyester, etc.), their cure behavior is qualitatively identical.
The brake drum mounts on the axle or wheel hub, and some drums incorporate the hub. Most brake drums are made of solid cast iron, but there are also steel and aluminum drums with cast iron liners. The machined friction surface on all drums is cast iron.
Brake Caliper Piston Products. In disk brake systems, the brake calipers are the ones that squeeze the brake pads against the disk or rotor of a wheel. One of the parts that make this squeezing action possible is the Brake Caliper Piston. When you step on the brakes, the pressure made by the brake booster or the master cylinder pushes the brake fluid through the fuel lines and out of the cylinders in individual wheels.
