space, aerospace, and aviation Precision Parts Cleaning Systems

Our cleaning solutions are engineered to satisfy rigorous aerospace specifications, including the widely adopted Water-Break-Free (Boeing BAC 5749) standard, as well as particle count protocols like IEST-1246. Systems can be tailored to meet OEM-specific or regulatory benchmarks such as NADCAP, FAA, or EASA cleanliness requirements

Depending on the part material and contamination type, we offer versatile methodologies:

• Ultrasonic Cleaning uses high-frequency sound waves to remove contaminants from intricate geometries with precision. Effective for engine parts, fuel injectors, and electronic components. 
• Tunnel washers
• Parts Washer Cabinets
• Return-to-Operator Systems 
• Rotary Basket Washers

Cleanliness is confirmed through multiple methods:

• Water-Break Test: A qualitative surface assessment that shows whether hydrophilic contaminants remain. 
• Residue & Particle Counting (Gravimetric Analysis): Quantitative evaluation via lab analysis or in-line monitoring to ensure compliance with specifications such as IEST-1246.
• Traceability & Documentation: Comprehensive logging of cleaning cycles, chemistry usage, and batch validation for audit and quality records.

Absolutely. Our cleaning systems are engineered for aerospace-grade materials such as aluminum, titanium, high-temperature alloys, and advanced composites. Optional stages like gentle ultrasonics, passivation, or tailored chemical cycles ensure safe and effective cleaning without damaging delicate substrates.

Our washers are automation-ready with support for:

• Robotic Loading & Unloading: Enables seamless integration into assembly or inspection cells.
• IoT & RapidSupport Monitoring: Allows real-time performance tracking, predictive maintenance alerts, and data-driven workflow optimization.
• Modular Multi-Stage Configurations: Combine wash, rinse, passivation, and dry in a single, configurable process ideal for streamlined production environments.

Better Engineering’s precision cleaning machines deliver clear ROI through:

• Reduced Chemical Consumption: Optimized wash cycles and recirculation systems lower detergent usage.
• Lower Labor Costs: Automation and high-throughput design minimize manual handling.
• Increased Throughput: Efficient cycle times result in faster turnarounds without sacrificing quality.
• Lower Waste & Disposal Costs: Our aqueous detergents and systems are environmentally safer and cheaper to dispose of.

Yes, our systems are engineered to support NADCAP-driven cleanliness and documentation requirements for aerospace programs. While NADCAP accreditation applies to your process and facility (not to a machine alone), we build washers and controls that make it practical to qualify, run, and audit a NADCAP-compliant cleaning process.

How we support NADCAP compliance:

• Process capability: Multi-stage spray/immersion (with optional ultrasonics), DI/low-TDS final rinses, cascading rinse designs, heated cycles, and HEPA-assisted or vacuum drying to minimize residue and FOD.
• Filtration & fluid control: High-efficiency filtration (down to single-digit microns as specified), oil separation, drag-out control, bath monitoring, and documented maintenance intervals.
• Materials & construction: 300-series stainless construction with sanitary piping options, cleanroom-ready designs, and chemistries compatible with aerospace alloys and downstream processes.
• Metrology & validation: In-house Millipore (gravimetric) testing and an automated high-power microscope for particle analysis and reporting to program specs.
• Controls & traceability: PLC/HMI platforms (Allen-Bradley, Siemens, Mitsubishi, Beckhoff) with recipe management, parameter logging, alarms, e-signatures, and optional MES connectivity for audit trails.
• Documentation support: IQ/OQ/PQ assistance, calibration records, and run/maintenance logs aligned with customer and prime requirements.

Bottom line: We configure and validate the washer to meet your prime cleanliness criteria and help generate the records auditors expect. Final NADCAP compliance depends on your end-to-end process and audit, and we partner with your quality team to get there.

Yes. Better Engineering offers cleanroom-ready precision cleaning systems designed for highly regulated environments such as medical devices, aerospace components, semiconductors, and other ultra-clean applications.  

Their cleanroom-capable features include: 

• Fully enclosed, stainless-steel construction with sealed doors and a drip-free design to prevent contamination. 

• Multi-stage wash → rinse → DI/low-TDS rinse → vacuum or clean-air dry sequences engineered for residue-free, repeatable cleaning.  

• Integration of automation, controls, and data capture (PLC/HMI, recipe memory, traceability) critical for regulated cleanroom workflows.

• In-house testing and validation (gravimetric, particle analysis, etc.) to ensure that the system meets your cleanliness standards before deployment.
