Vulcanizer: An important equipment used for vulcanization and molding of rubber products.

Working Principle

- Heating Principle: Using heat sources such as electricity, steam, and heat-conducting oil, the mold is made to reach the temperature required for vulcanization through heating plates, heating tubes and other devices, generally at 140℃-180℃, so that the rubber molecules undergo cross-linking reactions.

- Pressurization Principle: Relying on the hydraulic system or mechanical transmission system to provide pressure for the rubber vulcanization process, ensure that the rubber flows in the mold to fill the cavity, exhaust the gas, and make the product structure tight. The pressure is usually 10MPa-30MPa.

Structural Composition

- Main machine part: mainly includes upper and lower heating plates, with molds placed in the middle, and columns connecting the heating plates, etc., to provide space for heating and pressurization for vulcanization.

- Hydraulic system: composed of oil pumps, oil cylinders, hydraulic valves, etc., which can generate and control pressure so that the heating plate applies appropriate pressure to the mold.

- Electronic control system: including temperature controllers, pressure controllers, timers, etc., which can accurately control parameters such as vulcanization temperature, pressure and time.

Classification and specific types

- According to the operation mode: there are manual vulcanizers, semi-automatic vulcanizers and fully automatic vulcanizers. Manual vulcanizers require manual operation such as mold loading and unloading; semi-automatic vulcanizers are partially automated; fully automatic vulcanizers are fully automated, with high production efficiency and stable product quality.

- According to the structural form: there are flat vulcanizers and drum vulcanizers. Flat vulcanizers use flat molds for vulcanization and are suitable for rubber products of various shapes; drum vulcanizers use drum rollers as vulcanization components and are often used for continuous rubber products such as vulcanized tapes.

Advantage

• Adopts digital time relay for automatic mould clamping, timing alarm function. It can auto-stop, auto-exhaust, automatic timing, automatic fill pressure and automatic opening function, which can effectively pretect the fulfur and the suppression of products quality.

•Electric heating time using digital temperature controller with proportional control box display ammeter hot plate temperature and the working conditions of the heating element. With temperature control and high precision, intuitive display, easy adjustment. Steam heating with stainless steel metal hoses, reliable performance and durability.

•The hydraulic system uses a combination of double linkage pumps, both to improve efficiency and save energy. Low demand for oil, less failure, less noise.

•With automatic bleed function, and deflation and deflation time frequency adjustable

Application areas

- Tire manufacturing: used for vulcanization molding of tires for cars, bicycles, etc. to ensure the strength, wear resistance and sealing of tires.

- Rubber seal production: produce rubber seals, gaskets, etc. for various machinery and pipelines to ensure sealing performance.

- Rubber shoe production: vulcanize the soles and uppers of rubber shoes to improve the durability and comfort of rubber shoes.

Vulcanizing press is very important in the production of rubber products and plays a key role in improving production efficiency and ensuring product quality and performance.
