Seal Specifications

SPECIFICATION	DETAIL	text	text	text	text	text	text	text	text	text
Foam	Foam Seals are the most widely used seal for chamber blade systems. They come in a range of hardness and foam types to suit the printers varying needs and ink types. They are very economical when they are die cut but can also be water cut if the need to have a straight cut rather than the concave die cut edge. Both types have good retention of shape for consistent anilox contact.	text	text	text	text	text	text	text	text	text
Felt	Felt Seals can be supplied in different grades to suit the printers needs. They are usually cut oversize to allow for their compression to give better sealing properties against the anilox. They can be supplied as dry or be pre-soaked to give them longer wear life and better seal characteristics.	text	text	text	text	text	text	text	text	text
Rubber	Rubber Seals offer longer life but sometimes do not seal as well due to the anilox roll surface and the rubber causing a coefficient friction. The seals are usually injection moulded to suit each manufactured chamber type.	text	text	text	text	text	text	text	text	text
