How We Helped a Photonics Manufacturer Beat the "0.005 mm Challenge" — A True Story of Precision, Trust, and Partnership

Last year, a Canadian customer—an emerging innovator in the field of photonics—approached us with a tough request: “We need an aluminum part with a tolerance of ±0.005mm that needs to be masked before black anodizing. Can you do it?”

In short:

0.005mm is one-tenth the thickness of a human hair.

Even their internal team had trouble finding a supplier that could meet that spec or offer a viable alternative.

When they approached us, we reviewed the drawings. It was indeed a high-risk undertaking. But instead of giving up, we said:

“This is hard, but not impossible. Let’s figure it out together.”

Over the next few weeks:

• We analyzed anodizing tolerance variations

• Proposed partial masking + post-treatment approach

• Created test samples and analyzed feasibility with their engineers

• Maintained constant communication, even across time zones

In the end, we delivered a part that met standards in appearance and tolerance, with full inspection records.

Their team said:

"You solved problems that others dared not face. You not only made the parts, but also made our project come true."

Today, we continue to support them in the field of photonics contract manufacturing for neuroscience and telecommunications systems.

I think this is the meaning of cooperation. I share this case with you in the form of a story, hoping that you can better see the strength, sincerity and responsibility of our factory. We always take the customer's good as our goal, do our best to serve customers and become a reliable supplier

If you are also developing a new project and need CNC precision parts, we are happy to be your trusted partner.
