Rubber machinery is a type of machinery used to manufacture various rubber products such as tires, including general rubber machinery, tire machinery, and other rubber product machinery.

General rubber machinery is a machine used for preparing rubber materials or semi-finished products, including raw material processing machinery, rubber mixing machines, extruders, calenders, curtain canvas pretreatment devices, and cutting machines. Rubber mixing machines are divided into two types: open and closed. Open type rubber mixing machines are mainly used for hot refining, pressing, breaking, plasticizing, and mixing of rubber. Open type rubber mixing machines have been used in production since 1826, and their structure is relatively simple. They are still widely used in modern times; The closed rubber mixing machine is mainly used for rubber plasticization and mixing, and it has an additional mixing chamber compared to the open rubber mixing machine. Since the invention of the elliptical rotor sealed rubber mixing machine in 1916, sealed rubber mixing machines have rapidly developed in the rubber industry, and later other forms of rotor sealed rubber mixing machines have emerged. The rubber mixing cycle of modern closed rubber mixing machines is 2.5-3 minutes, and the maximum capacity of the mixing chamber is 650 liters. Extruder is a rubber machinery used for extruding tire treads, inner tubes, rubber hoses, and various rubber profiles. It is also used for wrapping cables and wire products. A common type is a screw extruder, which uses the rotation of the extrusion screw to stir, mix, plasticize, and compact the rubber material inside the barrel during operation, then moves towards the head direction, and finally extrudes a certain shape of product from the mouth. The rolling machine is mainly used for gluing or wiping the curtain canvas, pressing the rubber material, laminating and embossing. The first rolling mill was made and used for production in 1857, and has been continuously improved since then. Especially since the 1950s, the development of the plastic industry has greatly promoted the improvement of high-precision and high-speed rolling machines.

Tire machinery includes tire forming machines, tire bead ring machinery, tire shaping vulcanizing machines, capsule vulcanizing machines, pad vulcanizing machines, inner tube joint machines, and inner tube vulcanizing machines, as well as tire repair machinery, tire refurbishing machinery, and recycled rubber production machinery. More than 60% of the world's rubber is used to manufacture tires, so tire machinery plays an important role in rubber machinery. The tire forming machine is mainly used to fit and process various components such as rubber curtain, steel wire ring, and tread into the tire blank. According to different purposes, it can be divided into two categories: ordinary tire molding machines and radial tire molding machines. The process of forming a radial tire using a single molding machine is called the one-step molding method; The two-stage molding method refers to the process in which the tire body is made using a modified ordinary tire molding machine and then molded on a radial tire molding machine. Tire vulcanizing machine is a mechanical device used for vulcanizing the outer tires of inflatable tires in automobiles, construction vehicles, tractors, and airplanes. This machine appeared in the 1940s. On the shaping vulcanizing machine, operations such as tire loading, shaping, vulcanization, tire unloading, and post inflation cooling can be completed. The temperature, pressure, and steam chamber temperature of the superheated water inside the capsule can be measured, recorded, and controlled, and the entire production process can be automated.

Other rubber machinery products include machines used for making tapes, hoses, rubber shoes, model products, adhesives, and latex products.
