The Importance of Post-Processing: Degreasing and Cleaning Precision Machined Components
In precision machining, everything revolves around accuracy. Micrometer tolerances, high-grade materials, and complex geometries require extreme care at every step of the production process. Yet one crucial step is sometimes underestimated: post-processing in the form of degreasing and cleaning.
At Pillen Precision, this step is a fixed part of the production process. Using an advanced Dürr Ecoclean degreasing and cleaning machine, we ensure that components are delivered completely clean, residue-free, and ready for their next process step.
During the machining process, coolants and lubricants are used to dissipate heat and reduce tool wear. In addition, chips, micro-particles, and oil residues can remain on the surface of the component.
Without thorough cleaning, these contaminants can lead to:
✔ Poor adhesion during coatings or surface treatments
✔ Problems during assembly
✔ Accelerated wear of moving parts
✔ Reduced dimensional accuracy
✔ Rejection during quality inspections
✔ Oil residue on the final product (and within assemblies)
✔ Remaining chips in drilled holes or on surfaces
In the industries we serve such as high-tech, semiconductor, medical technology, and machine building absolute cleanliness is not a luxury, but a requirement.
Our Solution: Controlled Industrial Cleaning
For this critical post-processing step, we use an industrial cleaning system from Dürr Ecoclean. This machine is specifically designed for the high-quality cleaning of metal precision parts. (Machinery Pillen Group)
The advantages of this advanced cleaning technology include:
- Complete removal of oils, greases, and particles
- Reproducible and validated cleaning processes
- Suitable for complex geometries and internal channels
- Consistent quality, regardless of batch size
- Environmentally conscious and controlled process operation
By automating the process, we minimize human variation and ensure consistent end quality.
What Does Professional Cleaning Deliver?
-
Higher Product Reliability
Clean components perform better especially precision mechanical parts, where even minimal contamination can affect performance or lifespan.
-
Better Adhesion and Surface Quality
For parts that are coated, anodized, or otherwise treated, a clean surface is essential for optimal adhesion and a uniform final result. -
More efficient Assembly
Residue-free parts reduce disruptions in assembly processes and lower the risk of failure costs.
-
Less Scrap and Fewer Failure Costs
Preventive cleaning helps avoid problems further down the production chain, saving time, money, and unnecessary delays.
-
Professional Appearance
A perfectly clean semi-finished product reflects quality and craftsmanship—exactly what we stand for.
Cleaning as an Integral Part of Quality Assurance
At Pillen Precision, we do not see degreasing and cleaning as an extra step, but as an integral part of our quality strategy. Every component that leaves our production facility must not only be dimensionally accurate and precise, but also thoroughly cleaned.
By investing in high-quality cleaning technology from Dürr Ecoclean, we strengthen our position as a reliable and high-quality partner in precision machining.
Quality is in the details
In precision engineering, details make the difference. What is not visible at first glance microscopic contamination or oil residues can ultimately determine the performance of a final product.
That is why we ensure that every component:
✔ Is precisely machined
✔ Is thoroughly cleaned
✔ Is immediately ready for the next process step
This way, we deliver not just a product or component, but a complete and well thought-out solution.
