Tire vulcanizers are essential machines used in the production of pneumatic tires for vehicles such as cars, construction equipment, tractors, and even airplanes. These devices first appeared in the 1940s and have since become a crucial part of tire manufacturing. The vulcanization process involves loading, shaping, curing, unloading, post-charging, and cooling the tire all on the same machine. Temperature, pressure, and steam chamber conditions can be monitored, recorded, and controlled precisely. The entire production process is typically automated, improving efficiency and consistency. There are several types of tire vulcanizers, with the most common being the AFV, BOM, and AUBO models. In China, these are often referred to as Type A, Type B, and AB, respectively. The main differences between them lie in the design of the capsule and its handling mechanism. The AFV-type vulcanizer is known for its simple structure at the lower mold, which lacks complex central mechanisms. Instead, it features a single cylinder and a pneumatic pusher mechanism on the upper mold. At the end of the vulcanization process, the capsule is pushed into the bladder using a push-pull system. Steam is then introduced into the bladder, creating pressure that pushes the capsule into the inner cavity of the green tire, ensuring proper shaping and curing. The BOM-type vulcanizer uses a more complex central mechanism to control the expansion and contraction of the capsule. The capsule is held in place by upper and lower chucks, and during loading and unloading, it is straightened while the inner cavity is evacuated. Once in position, the capsule stands upright on the lower mold, ready for the next stage of the process. The AUBO-type vulcanizer features a capsule that is secured by clamping rings at both the top and bottom. It can be retracted into the barrel when not in use. When a tire is loaded, the bladder rises, allowing the lower bead of the green tire to make contact with the steel ring on the bladder. Then, the upper chuck lifts, and under the influence of shaping steam pressure, the capsule expands inside the tire. After vulcanization is complete, the bladder rises again, pulling the capsule back into the bladder via the upper chuck, while the lower chuck remains fixed, preparing the machine for the next cycle. Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.

This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
