Standard Test Sieve electroforming screen

Monday February-24 2025  16:52:25

Electroforming screen is also called micro-plate screen. It is produced by electrochemical method with the highest precision. In theory, the precision can reach 1 micron, and each mesh can be within the average error range, which is in line with ISO international standards. standard.

However, due to the extremely fine meshes of the electroforming screen, the screen is fragile and easy to crack, and the production process is complicated and expensive; it is suitable for laboratory fine powder inspection and inspection.

what are the advantanges of standard Test Sieve electroforming screen?

1. The mesh is precise and meets the specified standards, and the inspection certificate can be provided;

2. The flat mesh surface ensures the free flow of the sample;

3. The fine screen is supported by a hollow frame to reduce the damage of the mesh surface;

4. The edge of the screen frame is curled for safe operation;

5. Precision framework with consistent nestability;

6. The frame has good sealing performance, and there is no gap to lose material.
