about Primeblade sweden

Primeblade from PrimeBlade Sweden is a range of high quality doctor blades for the flexo, gravure, offset and coating industries, available with different edge types.To meet the increasing demands from the printing industry to achieve the highest and most consistent quality, together with the optimized blade life, Primeblade is only made using the highest quality of Swedish steel, and using the latest technology in grinding and polishing, to optimize the properties of the polished radius edge, grinded lamella or bevel edge. Primeblade doctor blades are available in all standard widths and thicknesses and supplied in 100m reels or cut to length in easy-to-use cassettes. The PrimeBlade Sweden team has a vast experience in doctor blade supply, and we are happy to provide our customers with auditing production processes, technical support and all information on a consultative basis to optimize the print result and improve bottom-line financials Primeblade is available with 3 edge profiles.

PROFILE 10 - Bevel edge - available in angles of 2 - 30 degrees

PROFILE 25 - Radius edge - double sided and polished for instant run-in

PROFILE 50 - Lamella edge - produced according to application and customer requirement. The most commonly used edge for low friction and wear.

Our wide range of services, support and advice around the world includes:

  • technical printing support
  • analysis of printing problems
  • information to optimize printing / coating performance
  • recommendations on best suited materials for production needs
  • metering and control in the transfer process

primeBLADE PRODUCTS

 

Primeblade 100

(Polymers)

The standard carbon steel used worldwide by printing houses. Unlike many of the low quality carbon steel on the market our 300 series has more carbides /μm2 in the steel microstructure.

Primeblade 300

(Carbon)

A better choice of blade when corrosion is an issue. Enhanced rust resistance properties when water based inks are used. Performs well against fast oxidation of the blade tip and abrasive conditions. Produced with a refined particle microstructure and denser particle distribution, helping to protect against steel particle contamination of the inking system. Hardened stainless steel and heat treated. Improves doctor blade life compared to carbon steel.

Primeblade 400

(Stainless)

Primeblade 500

(Refined stainless)

Used when extended lifetime is desired. Improved against fast oxidation of the blade tip and abrasive conditions, as well as against steel particle contamination of the inking system. Produced with an excellent particle microstructure and denser particle distribution. Hardened stainless steel and heat treated to reach our high quality standards. Excellent against corrosion problems when water based inks are used.

Primeblade 600

(Refined carbon)

Our 300 series times two—twice as many carbides/μm2. Wears down into much finer particles, causing less print complications and extending blade life. A high quality carbon steel, compared to other carbon steel blades.

Primeblade 800

(Micro alloyed tool steel)

Special micro alloyed tool steel with increased hardness and ductility for improved wear resistance and superior blade life.

Primeblade 900Nano 

(Nano-treated)

New revolutionary patented metallugic treated steel blades.  We're the only supplier of these exclusive and incomparable blades.

We developed them together with our partners in Nano technology because printers were looking for a solution to increase productivity, printing quality and reduce downtime due to lack of blade longevity.  The latest Nano technology has been used to optimize the properties and performance of the steel.

The blade will outlast any non-ceramic blade on the market, without any of the brittleness associated with long life blades.  The friction towards the cylinder or anilox roll is reduced by approx 40 - 60%.  Printing quality is significantly increased. Treatments do not have any of the harmful environmental side effects that the commonly used ceramic and nickel coatings have.

Primeblade Type 900 Nano advantages:

  • Longer life wear resistance
  • Perfect towards abrasive inks, such as white inks etc.
  • Less adjustment of the doctor blade chamber
  • Breaks down in much smaller particles
  • Reduction of 40 - 60% friction on the cylinder
  • Maximized print quality
  • Cleaner wipe
  • No ceramic particles involved
  • Less particles sticking to the blade

FLEXO CHAMBER SETTING

Use the same blade type and edge on both sides. There is less chamber pressure against the anilox and a more controllable and uniformed ink transfer. Different blade types can cause uneven pressure against the anilox.

Blade 4

COUNTER/ SUPPORT BLADE

To reduce doctor blade force and wear at cylinder ends cut back-up blade/ counter blade at an angle at each end. Upper cut (at the red line) in back-up/ counter blade must stop min 10–20 mm from cylinder end at full oscilla­tion on each side. Effect is lost if the cut point does not always stay on the cylinder surface area.

Blade 1

GRAVURE SETTINGS

Angle set-up is 55˚–65˚ against the printing cylinder for a cleaner wipe and less risk of ‘metal-hair’ forming on the blade edge. Lower angles increase the risk of print defects. Lower blade pressure can be used with a higher blade angle.

Blade 2

FLEXO CHAMBER DOCTOR BLADE MOUNT

When correctly mounted the grinding of the blade should not be visible, i.e. inside the chamber.

Blade 3

GRAVURE OR SINGLE BLADE FLEXO MOUNT

Mount the lamella doctor blade in the blade holder so the grinded side faces away from the printing cylinder or anilox.
