Quality
REDCATT ensures product quality through controlled manufacturing processes, full traceability, and integrated production systems.
Quality Philosophy
Quality at REDCATT is not based on final inspection alone — it is built into every stage of the production process. Our approach focuses on consistency and repeatability, ensuring that every unit meets the same performance standards from prototype to mass production.
Process Control
Controlled and repeatable manufacturing steps at every stage.
Verification
Process-level quality verification at critical steps.
Materials
Consistent materials and component sourcing.
Monitoring
Continuous monitoring and data collection.
Process-Driven Quality Control
REDCATT uses a process-controlled manufacturing approach, where each production step is defined, monitored, and recorded. By controlling the process rather than relying only on final inspection, we ensure consistent results across all production batches.
- Each assembly step follows defined parameters
- Operators follow controlled work instructions
- Critical steps include mandatory quality checkpoints
- Deviations are identified and corrected in real time
Traceability System
Full production traceability at component and product level enables root-cause analysis, improves consistency, and supports long-term product reliability.
- Tracking of materials and components
- Recording of production steps and operators
- Batch-level identification and history
- Data storage for quality analysis
End-of-Line Testing
All products undergo standardized end-of-line testing to verify performance before shipment.
- Electrical parameter verification
- Acoustic performance checks
- Functional testing
Material Control
Strict control over materials and components used in production ensures stable performance.
- Incoming material inspection
- Approved supplier management
- Controlled storage conditions
Environment Control
Production conditions are controlled to ensure consistent assembly quality.
- Clean filtered air for magnetic gaps
- Controlled temperature & humidity
- Organized production flow
