Xinhaisen Technology specializes in the high-volume manufacturing of precision metal shims through advanced chemical etching. We produce shims with exceptional flatness, consistency, and tight tolerances to meet the critical spacing and insulation needs of various high-tech industries. Our process ensures rapid turnaround without compromising on the superior quality your applications demand.
·Exceptional Precision & Consistency: We achieve ultra-tight tolerances as fine as ±0.01mm, ensuring every shim has a uniform thickness for reliable performance in critical assemblies.
·Burr-Free & Stress-Free Production: Unlike traditional stamping or laser cutting, our chemical etching process produces absolutely no burrs, heat-affected zones, or internal stresses. This preserves the metal's integrity and eliminates the need for secondary finishing.
·Wide Range of Materials: We can etch a diverse selection of metal materials to meet specific requirements for conductivity, corrosion resistance, or magnetism, including stainless steel, copper, brass, beryllium copper, and titanium.
·Rapid Prototyping & High-Volume Orders: Whether you need a quick prototype or a massive production run, our flexible etching process allows us to accommodate both urgent and super-large orders efficiently.
·Complex Designs with Ease: Chemical etching allows for the cost-effective production of complex geometries, including micro-features, without the high cost of hard tooling required for stamping.
