Product Description
Rubber Extrusion Line, EPDM Seals Production Line, EPDM rubber strip production line SJ-75
EPDM rubber seals production line producing process: Raw materials - Mixer - Rubber Mixing Mill - Extruder - Vulcanizing Box cooling and traction - packaging and storage.
The cold feel rubber extruder using forced feeding rollers which operating system design at the nearest workspace, humanized design will largely reduce the labor intensity of workers.
1. Qingdao Shun Cheong Machinery Co., Ltd has passed ISO9001: 2008 Quality Management System Certification and our products have qualified with Sweden SGS Certificate and CE Certificate.
2. Cold feed extruder using the overall welding of base, compact structure, safety, reliable, convenient and quick installation and commissioning.
2.1 Gear Reducer adopts the rectangle hardened reducer. Gears using high-quality high-strength low carbon alloy steel of 6 grade transmission accuracy, the tooth surface carburizing quenching and tooth grinding. With low noise, long service life and strong bearing capability.
2.2 Screw is the core component of extruder; Material is 38CrMoALA, after nitriding treatment, with wear-resistant, long life and high strength which can withstand high torque and high speed.
Our company has made unique design to the screw thread structure according to the clients' rubber seal technology requirements, which divided into sub-fast feeding, slow progress, mixing and other five phases.
2.3 Barrel is using cold, hot water circulation adjustment pumps or mold temperature device to adjust the temperature.
2.4 Motor with inverter control and adjustable speed.
2.5 Base: Steel plate welded structure, eliminating internal stress after annealing then machining.
Use: It applies to extrude and vulcanize various seals, EPDM, butyronitrile seals and so on.
