Rubber cutting machine

The production of rubber products involves a complex series of processes and equipment designed to transform raw rubber into a variety of final products. These products are widely used in a variety of fields such as automotive, construction, medical, consumer goods and industry. The production line of rubber products consists of multiple process steps, each of which requires specialized equipment to ensure efficient, quality and consistency of production.

1. Rubber compounding (mixing)
Purpose: Mixing raw rubber with various additives (such as vulcanizers, fillers, plasticizers, etc.) to achieve the performance requirements required for the final product.
Equipment used:
Banbury mixer: internal mixer used to mix rubber with additives. It makes the ingredients uniform through high shear force and is suitable for large-scale production of high-viscosity formulations.
Two-roll mixer: Mixes rubber and other ingredients through two high-speed rotating rollers. It is usually used for preliminary mixing or heating rubber to a suitable temperature to prepare for final batching.
Mixing and mixing system: In small batch production, or when a specific formula requires a specific rubber type, mixers and mixing equipment are used to prepare different rubber products.
2. Molding/Preforming
Purpose: To process the mixed rubber mixture into the desired shape or preform it to facilitate the subsequent vulcanization (cross-linking) process.
Equipment used:
Extruder: To extrude the rubber mixture into strips, sheets or tubes under high pressure, suitable for the production of long rubber products such as rubber tubes, sealing strips or wires.
Calender: To press the rubber material into thin sheets of uniform thickness, widely used in the production of rubber flooring, rubber pads and sealing materials.
Injection molding machine: Used to produce precision rubber parts such as seals, gaskets and automotive parts. The rubber is injected into the mold through the injection machine, heated and cured to form the desired shape.
Compression molding machine: Commonly used to produce larger rubber parts, suitable for the molding process of complex mold shapes and sizes.
Transfer molding machine: Combining the characteristics of injection molding and compression molding, it is suitable for the production of parts with complex details, and can improve production efficiency while ensuring accuracy.
3. Vulcanization/Cross-linking
Purpose: To cross-link the rubber molecular chains through the action of heat and pressure, thereby giving the final product the required elasticity, heat resistance and mechanical strength.
Equipment used:
Vulcanizer: By heating and applying pressure, the rubber is vulcanized in the mold, changing it from a soft material to a hard material with elasticity and stability. Vulcanizer is a key equipment for the production of rubber products and is widely used in the manufacture of automotive parts, seals, and rubber products.
Autoclave: Used to vulcanize large-sized rubber parts under high temperature and pressure, often used in large products such as tires and rubber tubes.
Continuous vulcanization production line: During the production process, the rubber material continuously enters the heating and vulcanization zone through a conveyor belt or roller to achieve continuous production. This system is suitable for the production of high-capacity products such as rubber profiles, sealing strips, and rubber tubes.
4. Cooling and post-processing
Purpose: Cool the vulcanized rubber products to room temperature and carry out necessary post-processing procedures such as trimming, inspection, and packaging.
Equipment used:
Cooling system: The vulcanized rubber products need to be cooled quickly to ensure their hardness and stability. Usually a cooling tunnel or water bath system is used to complete this process.
Finisher and cutter: Used to remove excess material or edge flash in the mold to ensure that the product surface is flat and the shape meets the requirements. These devices improve production efficiency and ensure that products meet quality standards.
Deburring equipment: Specially used to remove excess glue (burrs) on rubber products, usually as a step after mold production. Automated equipment removes flash and reduces manual intervention.
