As filtration technology continues to evolve, manufacturers are moving beyond conventiional drilling and punching methods toward precision-engineered flow control solutions.

At XINHAISEN, we utilize advanced Photochemical Machining (PCM), also known as precision photochemical etching, to manufacture high-performance metal filters, filtration screens, and custom flow-control components for demanding industries worldwide.

Unlike traditional mechanical processing, PCM removes material through controlled chemical dissolution, enabling the creation of highly precise openings, intricate flow paths, and burr-free structures without introducing mechanical stress or deformation.

Mechincal punching often creates burrs, Sharp edges, and contamination traps that can affect filtration performance and increase maintenance requirements.

Our photochemical etching process produces:

• Smooth edge profiles
• Burr-free apertures
• Mechanical stress-free
• No dead zones for particle accumulation
• Improved cleanability and service life

This makes etched filters articularyly suitable for medical, automotive, analytical, and high-purity applications.

Oure Precision etched filters and metal meshes are widely used in Medical Devices, Automotive Systems, Industrial Filtration etc.

XINHAISEN supports customers throughout the entire product lifecycle.
