The Evolution of Cleanliness: Why 70 MPa High-Pressure Water is the New Standard

Introduction

In the world of high-precision manufacturing—from automotive hydraulics to aerospace components—the definition of “clean” has fundamentally shifted. Standard washing methods are no longer sufficient to meet the rigorous ISO 16232 and VDA 19 standards. As parts become more complex, the industry is moving toward a more powerful, localized cleaning philosophy.

The Challenge: Hidden Contaminants in Complex Geometries

Modern CNC-machined parts often feature intricate internal channels, blind holes, and cross-drilled intersections. Traditional immersion or low-pressure spray washing often fails to reach these critical areas, leaving behind microscopic burrs and cutting fluids.

These “invisible” residues are the leading cause of:

• Sudden hydraulic valve failure.
• Increased friction and wear in precision assemblies.
• Costly recalls and compromised brand reputation.

The Solution: Targeted 70 MPa High-Pressure Jet Cleaning

This is where the industry is heading. Moving away from “batch washing” and toward targeted high-pressure cleaning.

By utilizing 70 MPa (approx. 10,000 PSI) water jets, manufacturers can achieve what was once impossible:

1. Effective Deburring: Removing hanging burrs that traditional methods miss.
2. Deep-Hole Penetration: Ensuring complex internal galleries are 100% free of debris.
3. Process Integration: Modern Jet Clean Centers, like our SC Series, are designed to sit right next to the CNC machine, enabling a seamless “One-Piece Flow” that reduces manual handling and contamination risk.

Conclusion: Future-Proofing Your Production

As the demand for electric vehicles (EVs) and high-efficiency hydraulics grows, so will the strictness of cleanliness specifications. Investing in high-pressure water jet technology isn’t just about meeting today’s standards—it’s about ensuring your production line is ready for the precision requirements of tomorrow.
