In the rubber and plastics industry, the quality of the final product is determined long before it reaches the mold or extrusion die. It begins in the compounding stage, where raw polymers, fillers, plasticizers, and additives must be precisely blended to achieve the desired physical, chemical, and rheological properties. At Guangdong Lixian Instruments Co., Ltd. , we provide essential testing equipment engineered to optimize this critical process. Our HZ-7048 Internal Mixer (Banbury-type mixer) is a versatile laboratory instrument designed for the preparation, testing, and development of rubber and plastic compounds, helping manufacturers achieve formulation consistency and material excellence -5.
Why an Internal Mixer is Essential for Rubber & Plastics R&D and QC
Unlike production-scale mixers, a laboratory internal mixer like the HZ-7048 allows manufacturers to simulate actual production conditions on a small scale -2-4. This capability is crucial for:
Formulation Development: Testing new combinations of polymers, fillers, and additives without wasting expensive production-scale materials -4.
Process Optimization: Determining optimal mixing temperatures, rotor speeds, and cycle times for new compounds -6.
Quality Control: Verifying the consistency of incoming raw materials and finished compounds.
Cost Reduction: Identifying the most cost-effective formulations while maintaining performance specifications.
The HZ-7048 Internal Mixer from Guangdong Lixian Instruments Co., Ltd. provides a controlled, efficient, and repeatable environment for these critical evaluations.
Key Features of the HZ-7048 Internal Mixer
Versatile Material Application: The HZ-7048 is designed to handle a wide range of materials essential to the rubber and plastics industry -5-7:
Rubber Compounds: Natural rubber (NR), SBR, EPDM, silicone rubber, nitrile rubber, and more for products like tires, seals, gaskets, hoses, and footwear.
Plastic Compounds: PVC, EVA, TPR, masterbatches, cable materials, and various thermoplastic compounds.
Additives & Fillers: Carbon black, silica, calcium carbonate, flame retardants, plasticizers, and colorants.
Advanced Temperature Control System: Consistent material properties depend on precise thermal management. The HZ-7048 features a夹套式 (jacketed) design for the mixing chamber, rotors, and ram, allowing for effective water cooling -5-7. This ensures that the heat generated during high-shear mixing is properly managed, preventing material degradation and guaranteeing stable, repeatable compound quality -1.
Optimized Rotor Design for Superior Dispersion: The rotors are engineered with precisely calculated spiral angles and working lengths to achieve optimal shearing, dispersion, and homogenization of materials -5-7. To ensure long-term durability, the rotor blade tips and end faces are overlaid with a wear-resistant hard alloy, capable of withstanding the high stresses of compounding abrasive fillers like carbon black -5-7.
Robust and Durable Construction: Built for the demands of a busy laboratory or quality control environment, the HZ-7048 features a rugged design with effective dust seals to prevent material leakage and contamination. The upper chamber and frame cantilever joint employ a secondary corner pressure seal for enhanced dust-proof performance -5-7. This robust construction ensures reliable, long-term operation with minimal maintenance.
Convenient Tilting Discharge Mechanism: The mixing chamber can tilt up to 110 degrees for quick and complete discharge of the compounded material, making it easy to clean between batches and streamlining the workflow -1-5-7.

How the HZ-7048 Enhances Rubber & Plastics Development
The HZ-7048 Internal Mixer is an indispensable tool for manufacturers seeking to improve their materials and processes:
Formulation Optimization: Experiment with new filler loadings, plasticizer types, or stabilizer packages to achieve target properties like tensile strength, elongation, or hardness -2-9.
Process Simulation: Replicate the shear rates and thermal history of production-scale internal mixers to ensure smooth scale-up from lab to factory floor -6.
Raw Material Validation: Test incoming lots of polymers, carbon black, or process oils to ensure they meet specifications and will perform consistently in your compounds.
Failure Analysis: When a product fails in the field, the HZ-7048 can be used to recreate and analyze the material compound to identify the root cause -2.
