The screen printing squeegee clamp, consists of an elastomer compound assembled in a clamp that holds it to the printing machine. The soft part, is made of polyurethane combining good mechanical strength and flexibility to transfer the ink through the screen printing screen. There are different formulations to reinforce the resistance to solvents and UV ink components, agents that have a tendency to deform the profile of polyurethane rubber.
Depending on the amount of ink that we have to apply, as well as the precision in the printing, we offer several types of hardness, ranging from 60 to 90 degrees shore. Our combined squeegees, with several laminated stripes, generally with the inner band of 90, and the outer faces with 65 or 75 shores, allow the screen printer to obtain prints with more definition and less ink deposit.
Our range of Ibeslab squeegees includes a variety of sizes and thicknesses to adapt to the requirements of each screen printing machine, be it flat, cylindrical or flat-cylindrical.
Ibeslab offer a wide variety of profiles from squeegees: straight edge for common applications, arrowhead for printing cylindrical objects, round edge for large ink deposit or bevelled for special applications. Since screen printing is the printing system that allows more ink to be transferred to the substrate, the geometry of the rubber together with its density broadens the range of possibilities to reproduce special effects.
It is usual to work with medium hardness and soft, straight-edged rubber. This gives good ink deposition without sacrificing definition.
Yes, for the contact of UV-curing inks and varnishes it is necessary to work with a special polyurethane formulation that is more resistant and does not deform.
It depends on the machine configuration and the design of the varnish to be printed. For high-volume varnish screen printing, we have three types of profiles available: straight, round and “V”. It is complex: our technicians will be able to advise you.
“Arrowhead” squeegee are the most common, although if the clamp can be positioned at an angle, straight-edged clamps are also suitable.
