Xinhaisen Sets the Standard in Photochemical Etching for Demanding Applications

Shenzhen Xinhaisen Technology Limited has established itself as a leading specialist in precision metal etching, serving a diverse array of global high-tech industries. The company's core mission is to deliver rapid, high-quality manufacturing of intricate metal components, from procurement of raw materials to final delivery.

The Precision Behind the Process: Photochemical Etching

Xinhaisen's expertise lies in its mastery of photochemical etching, a subtractive manufacturing process that allows for the production of complex, burr-free, and stress-free metal parts with exceptional accuracy. The streamlined workflow is key to their famed speed and reliability:

• Material Preparation & Cleaning: A variety of metal sheets (such as stainless steel, copper, aluminum, and alloys) are meticulously cleaned to ensure optimal adhesion for the photoresist.

• Photoresist Application & Imaging: A light-sensitive polymer is laminated onto the metal. Using a precise photographic tool, the desired component design is exposed onto the coated sheet.

• Developing: The unexposed photoresist is washed away, revealing the bare metal pattern that will be etched.

• Precision Etching: The sheets are sprayed with a controlled chemical etchant, which dissolves the exposed metal areas, leaving behind the desired intricate features.

• Stripping & Finishing: The remaining photoresist is removed, and the finished parts undergo thorough cleaning, inspection, and any required secondary processes (such as plating or forming).

This versatile process enables Xinhaisen to handle thicknesses from an ultra-fine 0.02mm to 1.5mm, achieving remarkable tolerances of ±0.01mm, micro-hole diameters as small as 0.03mm, and line widths down to 0.015mm.

Engineered Components Powering Innovation

Xinhaisen's capabilities translate into critical parts for advanced applications:
