Doctor Blade

Q: What is the difference between carbon steel and ceramic-coated blades?

The LongLife series adds an ultra-thin ceramic coating with a low friction coefficient that slows edge wear, extends blade-change intervals and protects the cylinder from micro-scratches.

Q: When do I need a stainless steel doctor blade?

Choose stainless steel when running water-based inks or corrosive coatings, or in humid environments - it resists oxidation and avoids rust-related streaking.

Q: What information do you need to quote my blade?

Width, thickness, length and the series you want are enough. Or send the machine model, ink system and press speed, or a photo of a used blade, and we will match the specification.

FAQ

What industries are carbon steel doctor blades used in?

They are mainly used in gravure printing, flexographic printing and industrial coating applications — packaging film, cigarette packs, labels, adhesive coating, lithium battery electrode coating and optical film production, wherever consistent ink or coating metering is critical.

How to choose the correct thickness?

0.15 mm is recommended for high-speed printing where fine ink metering matters, while 0.20 mm offers better wear resistance and stiffness for longer runs and coarser anilox or cylinder surfaces. If you are between the two, send us your press speed and ink system and our engineers will recommend the right thickness.

What is the difference between carbon steel and ceramic-coated blades?

Both use imported carbon steel, but the LongLife series adds an ultra-thin ceramic coating with a low friction coefficient. The coating slows edge wear significantly, so blade-change intervals are longer and the printing cylinder is better protected from micro-scratches — which is why it suits long runs and very high press speeds.

When do I need a stainless steel doctor blade?

Choose the stainless steel series when running water-based inks or corrosive coating chemistries, or when the press runs in a humid environment. Stainless blades resist oxidation, keep stable ink metering over long downtimes and avoid rust-related streaking on the printed web.

Do you support customization?

Yes. Custom width, thickness, length, packaging and material grade are all available. Blades are supplied as straight strips or coils cut to your cylinder face, and special tolerances or hardness grades can be produced against your drawing or a used blade sample.

What information do you need to quote my blade?

Width, thickness, length and the series you want (Standard, LongLife or Stainless Steel) are enough for a standard quote. If you are unsure, send the machine model, the ink system and press speed — or simply a photo of a used blade with its packaging label — and we will match the specification for you.

Can you provide samples?

Yes, samples are available for testing and evaluation on your press. Contact us with your specification and we will arrange the sample and shipping details.

What causes doctor blade streaking, and how do your blades prevent it?

Streaking usually comes from edge burrs, uneven wear or blade vibration. Our blades are precision slit with a burr-free edge, thickness is held to ±0.005 mm across the whole length, and straightness is inspected on every batch — three factors that keep blade pressure even along the cylinder and eliminate streak-related print defects.

What is the usual lead time?

Standard series in common sizes are typically produced in 7–15 working days. Fully custom lengths or special grades are confirmed individually at order stage, depending on complexity and current production schedule.

Do you ship internationally?

Yes. We export doctor blades worldwide with anti-rust sealed packaging suitable for sea and air freight, and we support customers across Europe, the Americas, Southeast Asia and the Middle East. Email dkeblade@163.com or WhatsApp +86 138 5558 8148 for shipping options to your country.
