Types of Chamber Seals

Chamber seals are used to ensure the ink used during the flexographic printing process does not leak out the ends of the seals.  A secondary purpose of these seals is to keep the blades in place to ensure the job can be done correctly.  Although it seems these seals could be universal it takes the right seal for the application to ensure the job is done correctly.  When all items in the doctor chamber are made of the correct material the results are gorgeous and attractive for the most attractive printing possible.

There are several different types of chambers seals that can be used, here are a few:

•    Foam seals – The most common and least expensive but often not the right choice for long press runs, higher press speed and particular chemical compounds.

•    Neoprene or rubber seals – Made for durability and are compatible with a variety of inks to be able to be used on multiple jobs without the need to be changed out.

•    Pre-soaked felt seals – Compatible with all types of inks and the perfect solution to resolve any leakage issues.  These seals are soaked in petroleum to help reduce friction and prevent the ink from building up on them.

Without the right chamber seal a printer will experience a massive amount of wasted inks in the printing process.  In order to make the flexographic printing process the most efficient it can be the right seals are needed to get the job done.  There are even some environmental chamber seals which are made from recycled material or biodegradable materials to ensure they break down after use and help to reduce waste.  As the most disposable part of the flexographic printing process these environmental chamber seals can be the perfect solution for a printing company that is attempting to be as environmentally friendly as possible.  With the right equipment the printing will be beautiful and highly accurate.
