Dear Reader,

Welcome to the third edition of our MetalWorks newsletter. This time, we take a close look at one of the most demanding fields: manufacturing ultra-fine filter structures and ready-to-install assemblies.

Learn how we provide laser-perforated sheets, well-defined process parameters, and deep vertical integration to meet the requirements of leading industries. And: What do our customers really think about us?

 

Best regards,

Jakob Dohse, Sebastian Wandel and Olaf Bittner

Trust in Numbers 
Customer Satisfaction

Why take our word for it? Better to ask the people who work with us every day. In our most recent customer satisfaction survey, we received clear feedback across all key areas – from product quality to support.

100% of our MetalWorks customers rated their trust in MeKo at least as good – 87% of them as excellent. Product quality and technical expertise received top marks as well, with average scores of 4.85 out of 5. And our customer support? Rated 4.82 – a strong signal that our service is reliable when it matters.

Additional insights:

• 100% rated communication as good or excellent
• 97% praised our packaging
• Over 96% were satisfied with delivery speed
• 96% evaluated our scrap rate as good or excellent

These results reinforce what we strive for every day: reliability, technical strength and open communication. Thank you for participating!

Sieves & Filters
From Sheets to Assembly

High-precision filters with hole diameters below 100 µm / 0.004’’ require more than just drilling – especially when delivered as ready-to-install assemblies.

At MeKo, sieves are laser-cut (with X-Y movement), while filters are drilled using stationary single-pulse perforation. This allows us to achieve hole diameters starting at 60 µm / 0.002’’ in sheets up to 0.5 mm / 0.02’’ thick, a ratio that requires excellent process stability. Precision, repeatability and minimal thermal load are key. This is where we excel, even for complex assemblies with flanges, frames or sealing systems.

Our manufacturing capabilities include:

• Laser drilling with defined, repeatable parameters
• Filter plates up to 1 m² / 10.76 sq ft (larger on request)
• Open area up to 40% (e.g., 60 µm /  0.002’’ = 8%, 100 µm / 0.004’’ = 15%, 300 µm / 0.012’’ = 30%)
• High level of vertical integration through assembly with welding, flanges, reinforcement frames, seals
• Easy cleaning and defined separation characteristics thanks to single-sheet design 

Use cases include:

• Filtration lines (food industry)
• CIP/SIP applications (pharmaceuticals)
• Resin and emulsion filtration (chemicals)
• Melt filtration (recycling)
• Process water & backflush systems (industrial engineering)

The result: robust filter solutions with precise geometry, high durability and fully integrated interfaces, ready to perform in your system.

Laser Drilling
Precision in Series

How do we drill hundreds of thousands of holes into one single stainless steel plate? With one laser pulse per hole – and a lot of know-how.

In the single-pulse drilling process, material is vaporized by a short but powerful energy input. A wide range of parameters such as focal position, pulse duration, gas pressure and nozzle gap determine the quality of this complex method.

Every job starts with a careful setup: test drilling, parameter adjustment, documentation. That’s how we ensure every filter plate meets its exact specification.

Thanks to in-house control systems and highly trained operators, MeKo delivers filter plates with hundreds of thousands of holes – efficiently, precisely, and reliably.
