RKS SYSTEM SQUEEGEE / SYSTEM SQUEEGEE HQ

The RKS squeegee blades are used worldwide, especially where an exceptional standardization of quality is required. The many attempts to imitate the RKS squeegee blade not only exemplify its importance but also prove its value to the screen printer within today's stringent production requirements.

The unique construction delivers repeatable, standardized results.

The RKS squeegee consists of a fiberglass spine integrally joined at its tip to an elastomer squeegee material.

In contrast to conventional squeegee rubber, the fiberglass blade retains its original form, remaining parallel to the printing plane throughout the operation.

A conventional squeegee changes shape radically and unpredictably during a production run, which affects the print quality of the entire job. Using the RKS squeegee with its original fiberglass spine effectively ensures repeatable screen printing results each time a job goes to press.

SAFE SCREEN PRINTING WITH LONGEST POSSIBLE SERVICE LIFE

RKS profile sections are supplied with durometer ratings of 55 to 80.

RKS has managed to apply the latest technological advances to achieve the best possible physical strength characteristics and resistance to solvents, along with optimized general performance.

This means that the service life of RKS screen printing squeegee blades now reaches levels believed to be impossible up to now.RKS squeegee blades require less application pressure than conventional blades.

This means that the printing templates are subject to less wear, leading to a general drop in mechanical stress for the entire screen printing machine.

IN GENERAL

The traditional squeegee does not allow a standardization in screen printing processes.

The effects of solvents and other ink ingredients change the squeegee material permanently.

The shore hardness of polyurethane is reduced and causes the screen printing squeegee to loose flexibility, immediately influencing the current printing angle and the set squeegee pressure.

This makes it impossible to keep the initial inking and the image definition constant over a print run.

Thus, screen printing will remain an experiment which is difficult to reproduce.

To solve these crucial problems, the RKS company has developed a squeegee system of its own, the well-known two-component product.

It consists of a hard-elastic carrier which provides a constant printing angle, a uniform squeegee pressure and uniform flexibility.

The second component, a soft-elastic Vulcollan strip, exclusively uses its accurate "print edge" to provide contact in the screen.

It must adapt itself to the different surfaces of the fabric and printing material in a sealing manner such that a transfer of ink can occur.

For the first time, this combination ensures an absolute plane-parallel print edge. The stable carrier blade excludes wavy printing streaks which frequently occur when traditional material is used.

The RKS squeegee system is available in heights from 20 to 145 mm.

We can offer shore hardnesses from 55° - 85° for the variety of screen printing applications.

Except for the 55° shore variant, all other types are available with a thickness of 6 and 8 mm.

The two different material thicknesses allow a very fine grading of the hardening effect the Vulcollan strips provide.

Example: Thanks to the hard-elastic carrier, 65° shore / 6 mm has a harder effect than 65° shore / 8 mm.

BLADE HEIGHT:

Up to 50 mm high squeegee blades are mainly intend for mounting into a conventional squeegee holder with an aluminium shim.

The 95, 105 and 115 millimetres high squeegee blades are fixed directly into the RKS squeegee holder.

The grater the height avoids any pollution of the squeegee holder.

NON STANDARD BLADE HEIGHTS:

Non-standard blade heights can be made on request.

For such heights the price of the next higher standard blade height will be calculated (profile height 30 mm = price from 50 mm).

BLADE DESIGN:

The squeegee blade is available in three different types:

1. type 00, blade thickness approx. 1,7 mm

2. type 00, blade thickness approx. 2,5 mm

3. type 32, blade thickness approx. 2,5 mm

(this thickness is reduces to 1,4 mm in the area of the PU)
