Import China Dispersion Kneader/ Rubber Kneader — Buy in Bulk from Supplier in China

The China Dispersion Kneader from China Dalian Second Rubber & Plastics Machinery Co., Ltd. is a closed-system mixing unit designed for high-viscosity rubber and plastic compounds. It operates under controlled temperature and pressure, with a typical batch capacity of 5 to 100 liters depending on model, and features a dual-rotor design with variable speed control up to 60 rpm. The machine includes a hydraulic lifting system for the mixing chamber and a sealed jacket for steam or cooling water circulation, ensuring consistent thermal management during processing.

The internal components are constructed from hardened stainless steel with a surface finish of Ra ≤ 0.8 μm to prevent material adhesion and contamination. Standard rotor profiles follow the Σ-type geometry, optimized for shear and dispersion without excessive heat generation. These machines are built to meet ISO 9001 quality system requirements, though no certification documents are provided in the listing. Typical materials processed include EPDM, NR, SBR, and PVC compounds, with viscosity ranges from 50 to 5000 Pa·s.

This kneader is primarily purchased by rubber product manufacturers producing seals, gaskets, automotive components, and industrial hoses. Buyers typically require batch consistency, low contamination risk, and ease of cleaning between color or compound changes. The supplier offers FOB Dalian port terms, with standard packaging in wooden crates and steel strapping. Lead time is not specified in the listing and must be confirmed directly. Minimum order quantity is not stated and should be verified prior to order placement.

China Dalian Second Rubber & Plastics Machinery Co., Ltd. is a manufacturer based in Ganjingzi District, Dalian, Liaoning Province, with a production facility covering 150,000 square meters. The company employs 530 staff, including 440 production workers and 86 engineering and R&D personnel. It has been operating since 1972 and specializes in rubber processing equipment, including internal mixers, open mills, dispersion kneaders, and calenders. The listing confirms no third-party certifications, export history, or client references, and response metrics are unavailable.

The supplier's trade profile indicates active manufacturing capacity but lacks verified export documentation, response rate, or lead time data. Buyers should treat this as a direct factory source with no intermediary layer, but must independently verify production capability, quality control protocols, and after-sales support. No claims are made regarding ISO certification, warranty terms, or overseas service centers. The absence of response data suggests communication may require direct inquiry via email or phone.
