UltraHard-Type HS-D

HS-D Mesh is a super strong mesh created using our unique Asada Mesh weaving technology. It is precisely woven with wire 3 times stronger than what has been used before, and has an opening rate of 40%, making it exceptionally strong under stress. Progress in improving mesh strength has been rapid.

Tensile strength of Supermesh HS-D is over 3 times greater than BS- Standard.
Produces more stable and dimensional accurate print plus it has an expected longevity of 2X-3X of conventional meshes.
Screen printing potential will be further enhanced.

Characteristic of Ultra Hard -Type HS-D:

• Engineered with Advanced Weaving Technology

HS-D Mesh is an ultra-durable stainless steel screen printing mesh developed using Asada Mesh’s proprietary weaving process. Manufactured from wire material with three times the tensile strength of standard mesh, it delivers exceptional resistance to elongation (≤5%) and ensures high dimensional stability under extreme printing stress.

• Enhanced Strength with Precise Weaving
The mesh features a 40% open area ratio, offering a balanced combination of ink release efficiency and mechanical rigidity. Compared with conventional meshes, HS-D maintains a significantly higher yield point, confirmed by tensile test measurements.

• Superior Dimensional Accuracy Under Stress
When paired with a low-distortion screen printing plate, HS-D Mesh can operate at 2.5x the typical snap-off distance without visible warping or skew. Dimensional accuracy in high-stress printing zones remains intact—ideal for PET film or low-absorption substrates.

• Proven Stability Over 20,000 Prints
HS-D Mesh was subjected to a 20,000-print durability test using elevated snap-off settings. Results showed distortion fluctuation within ±15 microns, validating long-run consistency for industrial applications.

• Ideal for High-Viscosity & Multilayer Applications
Thanks to its ultra-high strength and stability, HS-D Mesh enables precise printing with high-viscosity pastes and multi-layered circuit patterns on flexible thermistor substrates. Even in large-area mask printing, dimensional integrity is fully preserved.
