For over 13 years Xinhaisen has pioneered developments in photochemical etching, achieving standards admired by the industry and appreciated by a global customer base from a wide range of high-tech engineering markets.

Since found in 2012, in affiliating with our customers we have pioneered many new production techniques and methodologies in order to better serve their needs. It is these techniques that have advanced our capabilities further, enabling us to take what was once considered art and turn it into a science.

Now, we became China's leading photochemical etching specialist, with also the capacity of offering stamping and laser-cutting service. Our products include etching bipolar plates for fuel cell, speaker grills,  micro meshes&filters, tea&coffee infusers, shims&gaskets, Optical encoderdisk&strip, EMI/RFI shielding, Leadframes, connectors&contacts, printingstencils&foils and metal crafts.

Quality and service is our mission, Xinhaisen is committed to pursuing the highest standards of environmental performance. Responsibility for sustainability resides with all employees. The company has achieved ISO 14001 and IS0 9001 and IATF 16949 and is committed to maintaining that standard. With a fast response, high quality, best service and fair price, we have gained high reputation from our customers all over the world.
