Rubber Two-Component Production Line Process

Time：

2021-06-07

The two‑stage rubber extrusion production line consists of two rubber extruders connected via a common composite die head, enabling co‑extrusion to produce finished products. Since the primary function of a rubber extruder is extrusion molding, the extruded product must subsequently undergo shaping and curing. Therefore, after extrusion, the material passes through a 30‑meter hot‑air curing oven for in‑line setting. This two‑stage rubber extrusion line combines an extruder of type 90 with one of type 65 to achieve composite extrusion. The specific model configuration of the extruders required for this composite line is determined by the size of the rubber product and the desired proportion of each rubber compound within the final item. In rubber manufacturing, composite extruders are primarily used for producing tire tread compounds, automotive sealing strips, colored bicycle tire treads, laminated hoses, plastic–rubber composites, and multi‑layer co‑extruded rubber sheets. Composite extrusion technology represents a highly advanced process in the rubber industry, allowing manufacturers to tailor formulations and material properties according to specific performance requirements. By employing composite extrusion equipment, it is possible to both reduce material consumption and achieve products with diverse functional characteristics. Rubber extruders are fundamental machinery in the rubber industry and play a critical role in determining product quality, particularly in the production of tires and various rubber goods. Internationally, the evolution of rubber extruders has progressed through several stages: plunger‑type extruders, screw‑type hot‑feed extruders, conventional cold‑feed extruders, twin‑screw cold‑feed extruders, vented cold‑feed extruders, pin‑type cold‑feed extruders, and finally composite extruders. Hebei Shuangda Rubber & Plastics Machinery Co., Ltd. is a modern enterprise integrating research, development, manufacturing, and sales of complete sets of extrusion equipment for rubber, silicone, and plastics. Its main product lines include rubber extruders, rubber hose extrusion lines, three‑component sealing strip extrusion lines, silicone sealing strip production lines, plastic sealing strip production lines, plastic profile production lines, plastic pipe production lines, elastomer extruders, and other extrusion equipment. Additionally, the company manufactures production machinery for engineering seals, automotive seals, wire and cable applications, air‑conditioning hoses, braided hoses, automotive hoses, waterstop strips, and related products.

The two‑stage rubber extrusion line consists of two rubber extruders connected to a common composite die, enabling co‑extrusion by both units to produce molded extrudates. Since the primary function of a rubber extruder is extrusion molding, the products must undergo shaping and stabilization after extrusion; therefore, following extrusion, they are passed through a 30‑meter hot‑air curing oven for in‑line setting. The two‑stage rubber extrusion line comprises one… 90 a rubber extruder and one 65 Two extruders of the same type are used for co‑extrusion production. The specific model configuration of the extruders required for the co‑extrusion line is determined by the dimensions of the rubber product and the target proportion range of the two rubber compounds in the final product.

In rubber industry production, co‑extruders are primarily used for extruding tire compound treads, automotive sealing strips, colored bicycle tire treads, composite hose and plastic‑rubber co‑extrusion, as well as multi‑layer co‑extrusion of rubber sheets. Co‑extrusion technology represents a highly advanced process in the rubber industry; it allows for the use of compounds with varying formulations and properties to meet diverse product performance requirements, enabling the production of components that both conserve materials and satisfy multiple functional needs.

The rubber extruder is a fundamental piece of equipment in the rubber industry and one of the key machines that significantly influence product quality, playing an essential role in the production of tires and rubber goods. The evolution of rubber extruders abroad has progressed through several stages, including plunger-type extruders, screw‑type hot‑feed extruders, conventional cold‑feed extruders, twin‑screw cold‑feed extruders, vented cold‑feed extruders, pin‑type cold‑feed extruders, and compound extruders.
