Chambered dr blades

Post by MShalna »

Hello fellow printers...I am seeking advice on dr blade specs/brands that anyone might have based on their experience with chambered dr blade units. It is my understanding that the metering blade should be more firm/rigid whereas the containment blade should be more flexible. How much more? Is there a value that anyone goes by when ordering these 2 types of blades? Do you use 2 different materials (steel/plastic etc.)?

Anyway, any advice would be helpful. The chambered units that I'll be using in the near future are about 52" wide. They will be the units that come with the 51" wide BOBST Vision CI press.

I don't believe so...It is a quick change chamber that can be removed and worked on outside the press...Really all I know..

Ours are bladders . It’s a nice set up and fast changing in press. But when blades go you need to tear apart the entire unit

You can see the air fitting . Black things poking out are the blades

You connect airline to the fitting the steel pieces with x’s on them raise up and blades pop out

I recently got to see a live presentation of the press...The chambers do not have a bladder system.

depending on what you're printing with i find the daetwyler gamutstar for high LPI or starlife/optilife for low LPI. surprisingly pearlescent/high grit inks last 10x as long with starlife coatings and optilife coatings work 10x as long with slip inks/channeled anilox. which type of anilox and volume/density are you looking to acheive? and is this narrow/wide web?

Thanks for the advice. It will be wide web (50" print width) We plan on using high line screen aniloxes initially. We did purchase a 700 and 800 line screen for trialing...Nothing to heavy for coating...for now.

good blades with a good coating are well worth the money IMO, daetwyler has never steered me wrong.
