For high-end lithium battery slurry mixing systems, each twin screw barrel must meet strict material and dimensional accuracy requirements.
To ensure consistent performance, our inspection process covers raw material verification, in-process control, and final product certification.
The ZT615 nickel-chromium alloy, developed through powder metallurgy technology, is independently researched and produced to ensure microstructural uniformity and long-term stability in corrosive environments.
Each batch of alloy powder is accompanied by a chemical composition and microstructure analysis report, ensuring traceable quality from raw material to finished component.
Every extruder barrel undergoes a multi-stage quality control workflow:
Material Verification – Alloy powder tested for chemical composition, density, and particle uniformity.
Hardness & Impact Test – Measures surface and core hardness, impact resistance, and mechanical toughness.
Wear and Corrosion Testing – Evaluates long-term stability in NMP and abrasive slurry conditions.
Dimensional Precision Check – Full 3D scanning and CMM (Coordinate Measuring Machine) inspection to verify geometry and tolerance.
Final Quality Review – Independent confirmation of all reports before shipment.
To ensure consistent inspection and processing results, we establish Standard Operating Procedures (SOP) and Standard Inspection Procedures (SIP) tailored to customer requirements.
Each document clearly defines:
Inspection items
Acceptance standards
Testing methods
Evaluation criteria
These documents standardize every key operation — from machining to assembly and inspection — ensuring accuracy, repeatability, and efficiency across production batches.
Through integrated quality management and strict documentation control, every twin screw barrel maintains:
Uniform hardness and microstructure
Reliable wear and corrosion resistance
Accurate dimensional alignment (±0.02 mm)
Traceable inspection records for long-term assurance
This comprehensive approach helps users maintain stable production, minimize downtime, and achieve consistent slurry mixing quality.

Q1: What kind of inspection reports can be provided?
Alloy powder composition, hardness, impact, wear, corrosion, and 3D coordinate measurement reports are available upon request.
Q2: How do SOP and SIP improve quality consistency?
They define standardized testing and acceptance criteria, ensuring every product meets the same performance benchmarks regardless of production batch.
Q3: Is ZT615 a proprietary alloy?
Yes. It is independently developed using powder metallurgy to achieve superior corrosion resistance and structural uniformity for lithium battery slurry mixing environments.
Q4: Can reports be tailored to customer standards?
Yes. Inspection content and report format can be customized to meet specific project or OEM requirements.
