Automotive & Electrical Vehicle (EV) Parts Washers
for OEM & Tier Suppliers

Our automotive parts washers are engineered to clean a wide range of components, including engine blocks, transmission housings, EV battery trays, and reusable dunnage. Whether you need precision cleaning for delicate parts or heavy-duty degreasing, our systems can handle it.

Aqueous parts cleaning uses water-based detergents and high-pressure spray technology, making it safer, more sustainable, and more cost-effective than solvent systems. It eliminates grease, oils, and carbon buildup without the hazards associated with solvent use.

Yes. Our EV parts washers are designed to clean battery housings, cooling plates, and other sensitive components using gentle but effective aqueous processes, ensuring compliance with strict cleanliness requirements for electric vehicle manufacturing.

Absolutely. We build specialized engine cleaning machines and engine block washers that remove oil, carbon, and machining residues from even the largest castings. Heated wash stages and advanced filtration ensure consistent results.

Yes. Our industrial parts washers, including tunnel and conveyor-style models, are designed for continuous operation in high-volume environments. They deliver consistent, repeatable cleaning for automotive assembly and remanufacturing lines.

Many of our washers can be configured as dunnage part washers, capable of cleaning both returnable packaging and metal or plastic automotive parts. This flexibility reduces equipment costs while ensuring all handling materials remain contamination-free.

Better Engineering stands out in the automotive sector by combining deep industry expertise with purpose-built engineering for high-volume production environments. Our industrial parts washing systems are designed to meet the exact needs of OEMs and Tier 1/2 suppliers—with features and performance that many manufacturers can’t match.

Here’s how we compare:

Built for true throughput. Our automotive/EV washing solutions feature multi-stage, high-capacity designs, heated wash & rinse cycles, robust filtration, heavy-duty construction, and smart automation, so components such as engine blocks, transmissions, battery trays, cooling plates, and stamped parts move through the cleaning process quickly and reliably.

• Integration with automation & industry standards. While some manufacturers focus only on basic batch washers, we support full conveyor systems, robotic loading/unloading, PLC/MES connectivity, and compliance with automotive cleanliness standards such as ISO 16232 and VDA 19.
• Extensive customization & testing. We test your parts in our Engineering Process Lab, tailor the machine design (spray, immersion, ultrasonic, or any combination), and deliver systems optimized for your specific part geometries, contamination type, cycle times, and line layout.
• Depth of experience. With over 60 years in the parts washing business, extensive in-house engineering and control capabilities, and ISO-9001 certification, our team is equipped to solve advanced cleaning challenges that many manufacturers shy away from.
• Full lifecycle support. Beyond producing the machine, we offer installation, commissioning, ongoing service, and parts support. Our focus is on uptime and consistent output, two metrics that matter in automotive production.

In short, if your operation demands high throughput, automated integration, stringent cleanliness standards, and tailored engineering for the automotive or EV space, Better Engineering offers capabilities that many standard washer manufacturers do not. You’re not just buying a machine, you’re investing in a cleaning system engineered to match your production rate, component variety, and quality expectations.

Yes. Better Engineering can perform and validate Millipore (gravimetric) testing as part of our cleanliness verification process. Our in-house Engineering Process Lab is equipped to collect and analyze contamination from test parts, measuring both particle mass and size distribution to confirm compliance with cleanliness specifications. We also utilize an automated high-power microscope for detailed particulate inspection and documentation, ensuring reliable, repeatable results that meet industry standards for validation and reporting.

Yes. Better Engineering designs systems to achieve ISO 16232 (and VDA 19) cleanliness levels for automotive components, provided the process is properly validated with your parts, soils, and cycle-time targets.

How we support ISO 16232 compliance:

• Process engineering: Multi-stage wash/rinse/dry with DI or low-TDS final rinse, cascading/recirculating rinses, heated cycles, vacuum or controlled clean-air drying.
• Filtration & fluid management: High-efficiency inline filtration (e.g., down to single-digit microns as specified), oil separation, and drag-out control to prevent re-deposition.
• Fixturing & coverage: Custom fixtures, precision nozzle placement, programmable flow/pressure, and part rotation/agitation for complex geometries and blind passages.
• Measurement & validation: In-house Millipore (gravimetric) testing and automated high-power microscopy for particle mass/size analysis, with documentation aligned to ISO 16232 sampling protocols.
• Controls & traceability: PLC/HMI platforms (Allen-Bradley, Siemens, Mitsubishi, Beckhoff) with recipe control, parameter logging, alarms, and optional MES connectivity for audit trails.

Note: Final conformity to ISO 16232 depends on end-to-end process validation (parts, soils, chemistry, handling, and inspection). We offer free lab testing to confirm the specification before you commit.
