What is the production process of rubber tubing? In order to ensure that the rubber hose is under pressure during the vulcanization process, it is wrapped in water cloth, rope or lead after molding, and then vulcanized. Sulfurization can be achieved through direct steam heating in a vulcanization tank or continuous vulcanization. The basic processes of rubber hose production include rubber mixing processing, cord and canvas processing, rubber hose molding, vulcanization, etc. The production process of rubber hoses varies depending on the structure and skeleton of the hose, and the processing methods and molding equipment for the skeleton layer are also different.

Full rubber hose, as it does not contain a skeleton layer, only requires the use of an extruder to press out the hose; The sandwich rubber hose requires the use of a molding machine that wraps the adhesive tape onto the inner adhesive layer; When forming the suction hose, it is necessary to first wrap it with a metal spiral wire and then wrap it with internal adhesive; Weaving and winding rubber hoses require the use of specialized fabric weaving machines or winding machines; Knitted rubber hoses require the use of knitting machines, etc.

The production process of rubber hoses can be divided into core method (including soft core method and hard core method) and coreless method according to whether the core is used or not. The core method refers to the molding of rubber hoses on hard or soft cores, while the coreless method directly molds the skeleton layer and outer rubber layer on the extruded inner rubber hose.

The production process of rubber hose short fiber rubber hose is to directly add short fibers into the rubber material, and then press them out to form. The production process of rubber hose is simple, and it will gradually replace knitted rubber hose and cloth clamped rubber hose. The production process of modern rubber pipes tends towards highly continuous and automated production. The use of thermoplastic rubber or plastic can eliminate the vulcanization process and greatly simplify the production process.
