silk screen scraping gum hardness range: tolerance + / - 3 A.

 55-65 - A  belongs to low hardness rubber, suitable for medium pressure, the low wire mesh cloth, low viscosity inks, printing on the surface of the irregular.

 70 A- 75 A  belongs to the stencil, suitable for high pressure and all kinds of mesh screen cloth and high viscosity ink of various printed materials.

 80 A  - 95A  belongs to the high hardness of the stencil, suitable for high pressure, suitable to all type of wire mesh cloth and high viscosity of the fine print ink printing, high resolution, low ink deposition.

 Squeegee blade shape and scope of use:

M1 flat gum blow: the most common shape, wide application range, has a certain resilience, can be repeatedly grinding, suitable for all kinds of printing.

 M2, M3, pointed gum: good flexibility and adaptability, applicable to the uneven surface and irregular shape printing, can effectively control the ink, printing resolution is high.

 M4, M5 is blunt gum: a flat scraping and sharp characteristics, can better control the printing Angle, better control of the scraping ink.

 M6 round gum blowing: suitable for thick printing printing, printing the bottom of the black and white.

 M7, M8 composite plastic blow: level of different hardness has played a supporting role, make the stencil will not bending deformation, can effectively control the printing pressure, to prolong the cycle the stencil.

 M9 square stencil: suitable for solar cell substrate and various kinds of printed circuit boards.
