Frequently Asked Questions

What is sintered metal filtration?

Sintered metal filtration involves compacting and heating metal powders to form a porous structure. This creates durable, high-strength filters with precise pore sizes ideal for demanding industrial applications.

Can your filters be cleaned and reused?

Yes, our sintered filters are highly regenerable. They can be backwashed, ultrasonically cleaned, or chemically treated without degradation, offering long-term cost savings.

Do you offer custom sizes and shapes?

Absolutely. We provide full customization — from diameter and thickness to pore size and connection types — based on your technical drawings and specifications.

What industries use your titanium felt?

Our titanium fiber felt is widely used in hydrogen fuel cells, electrolyzers, aerospace systems, and medical devices due to its conductivity, corrosion resistance, and biocompatibility.

Is your production ISO certified?

While not explicitly stated, our manufacturing processes follow international quality standards, serving state-owned and global enterprises with consistent, reliable output.
