Doctor blades are the key to successful production but choosing the best one for your needs is often a complex process. You need to know your intended application, as well as the advantages and drawbacks of different blade types. Fortunately, we are here to help. Before you order new blades, consider some of the best uses for two styles you can buy:
- Metal Blades – The material of choice for high-quality and repeatable doctoring results, these blades come in several forms. Each one has its advantages, such as the long life of tool steel blades or the corrosion resistance of stainless steel. The important thing to remember is that metal should be your go-to for doctoring that’s consistent across numerous jobs.
- Plastic and Composite Blades – Certain flexo, coating, and gravure applications require cost-effective performance but not necessarily the benefits of metal blades. A couple of examples would be applications that use low screen count anilox rolls or corrugated applications. You can count on plastics and composites to deliver this performance. These blades tend to have a long life at high speeds and are ideal for use on laser-engraved ceramic anilox rolls.
Are you still unsure which blades you should buy? Don’t be afraid to ask an expert! A reputable supplier should be happy to work with you to determine the best product for your situation.
When it comes to printing applications, your choice in consumables makes all the difference. One of the most critical pieces in your arsenal are your end seals. Unfortunately, the wear they face during high-speed printing processes means that they may need replacement sooner than you would like.
If your seals are not lasting as long as you need, it’s crucial to get new seals that deliver the level of performance you desire. With modern technology, most seal designs are easy to replicate when you use the right provider. The key is recognizing which supply companies give you the best product for your money.
For long-lasting seals that support your success, you want a partner that uses high-speed CAD cutting equipment to produce durable replacements. This state-of-the-art approach offers the best balance of speed, customization, and quality. Most importantly, it avoids many of the problems with traditional die-cut seals, such as:
- Concave Edges
- Chamber Leakage
Depending on your needs, you might also want an alternative material or chamber-specific seal geometry change. This is where custom design and material capabilities that include foam, rubber, felt, and composite design makes a massive difference. By working with suppliers who have a versatile range of products and the ability to tailor their production to meet your needs, you get the best possible results.
