2018-05-22
The EPDM rubber extrusion‑crosslinking production line is primarily designed for the efficient extrusion and rapid, continuous crosslinking of small- and medium‑size EPDM products. Developed by our company, it integrates advanced international technologies with years of domestic manufacturing expertise. The line comprises an EPDM extruder, a high‑temperature pre‑crosslinking oven, and a hot‑air circulation curing tunnel. By employing a tailored compound formulation, it eliminates the need for a microwave crosslinking unit, reducing capital investment by more than 50%, cutting electricity costs by over 40%, and saving more than 50% of floor space compared with conventional equipment.
The EPDM rubber extrusion and vulcanization production line is primarily designed for the efficient extrusion and rapid, continuous vulcanization of small- and medium-sized EPDM products. Developed by our company, this line integrates advanced international technologies with years of domestic manufacturing expertise.
The EPDM rubber extrusion and vulcanization production line consists of an EPDM extruder, a high‑temperature pre‑vulcanization oven, and a hot‑air circulation drying tunnel. It employs a compound formulation process and does not require a microwave vulcanization unit, reducing equipment investment by approximately 50% compared with existing systems.
Moreover, it can reduce electricity costs by more than 40% and save over 50% of the land footprint.
EPDM extruder
This machine is a single-screw extruder, comprising an extrusion die, a barrel, an automatic feeding device, an electrical control system, a water‑cooled and heated cooling system, and a mold temperature controller.
Technological features:
1. The screw’s length-to-diameter ratio reaches 20:1, ensuring thorough plasticization of the compound, excellent extrudate density, and a smooth surface both internally and externally.
2. The die‑head snap‑ring design enhances extrusion performance and allows for easy mold installation, removal, and cleaning.
3. Equipped with a variable-frequency motor and inverter control, the machine maintains excellent stability and reliability across both high- and low-speed operation.
4. Equipped with an automatic feeding device, it ensures stable and uniform material feed and allows for convenient disassembly and cleaning.
5. The barrel and water channels are integrated into a single unit, employing an external helical flow path to ensure consistent cooling and temperature control.
6. The screw, die head, and feeding unit are all equipped with water‑cooled temperature‑control systems, enabling stable, long‑term operation and delivering excellent extrusion performance for rubber compounds of varying hardnesses.
7. It can achieve extrusion effects for other materials both inside and outside the sheath.
