Import Cold-Feed Extruder — Buy in Bulk from Supplier in China

The cold-feed extruder from China Dalian Second Rubber & Plastics Machinery Co., Ltd. is engineered for processing rubber and plastic compounds with a focus on reliability and temperature stability. The machine features an optimized screw and barrel design to accommodate varied formulations and process requirements, while water-cooled contact parts and a thermostatically controlled system ensure consistent extrusion quality. Its design improvements over conventional extruders enhance serviceability and economic performance for compound producers.

Constructed with wear-resistant materials in critical zones, the extruder handles abrasive compounds typical in rubber processing, such as EPDM, SBR, or natural rubber. The screw geometry is tailored to minimize heat buildup, a key factor for cold-feed operations where material is fed at ambient temperatures. Standard industry practice for such extruders includes a length-to-diameter ratio of 12:1 to 20:1, though the exact configuration depends on the supplier’s customization.

This extruder is used in tire manufacturing, hose production, and profile extrusion lines where consistent output and material homogeneity are critical. Buyers typically source it for mid-to-large scale operations, with trade terms often negotiated per project scope. The machine’s modular design allows integration with downstream equipment like calenders or vulcanization lines, reducing setup time for compound producers.

China Dalian Second Rubber & Plastics Machinery Co., Ltd. is based in Ganjingzi District, Dalian, Liaoning Province, with a facility covering 150,000 square meters. Established in 1972, the company operates from a manufacturing hub in northern China, serving domestic and international markets with rubber processing equipment. The address places it in a key industrial zone for heavy machinery production.

The supplier employs 530 people, including 440 production workers and 86 engineering and research staff, indicating a focus on both manufacturing capacity and technical development. Its product range includes internal mixers, open mills, dispersion kneaders, and Banbury mixers, positioning it as a specialized provider for rubber compounding lines. The company’s industrial output value is reported at 150 million yuan, reflecting a mid-to-large scale operation in the sector.
