Parts as humble as end seals play an essential role in the printing process. When these parts are not made to exact specifications, leaks result. And these chamber leaks make a big mess, waste ink, and degrade the end product. Starting with a well-made seal from the suitable material and precise measurements are what ensure quality and success.
You’ve experienced the problem with poorly made seals on your press. These include chamber leaks that cause wear and tear on doctor blades, printing quality reduction, and production downtime. However, when these seals are made to order, all of that reverses. Look to Allison Systems Corporation to manufacture custom end seals for your commercial printing presses.
Making Custom Seals for Your Presses
We use state-of-the-art, high-speed CAD equipment during the crucial cutting process. Our process enables us to customize parts and make them with the quality want and in the quantity you need. We don’t die-cut end seals as compression from this process causes the seals to warp, leak, and contain concave edges.
Depending on your needs, we make seals of foam, neoprene, felt, or composite. Talk to one of our team members about the best seals for your operation.
Doctor blades made from steel are known to produce excellent results on high line screen anilox rolls and other difficult metering applications. However, as with all doctor blade materials, steel doctor blades do have some disadvantages. When incorrectly applied, they can produce metal fragments which could lead to anilox scoring. Additionally, operators also have a risk of cut hazards when handling used steel doctor blades if the proper PPE and procedures are not utilized.
Plastic blades can offer a better option than typical carbon steel doctor blades when used with certain applications. Plastic blades work best when metering water based inks on lower line screen anilox rolls typically less than 500 LPI. Plastic blades will provide longer life when compared to carbon steel blades, will not corrode with water based inks, will not release fragments that can cause anilox scoring, and will reduce the potential for cut hazards. Please be aware that worn Plastic blades will present a cut hazard and proper PPE and procedures will still need to be followed when handling them. They are a popular option for corrugated applications and containment blades on chambered inking systems.
There are many choices when it come to materials and edge shapes. Contact us so we can discuss your application to determine if Plastic blades are a good option for your jobs.
