Learn everything you need about TMNetch and our high-quality photochemical etching solutions.
Founded in 2011, TMNetch Precision Etching Technology Co., Ltd. is a leading photochemical etching manufacturer in China. We have a 4,000-square-meter factory in Dongguan with five fully automated 39-meter lines, and we supply precise parts to more than 20 countries.
Our 100-plus engineers and chemists provide prototypes within 6 hours, create tight tolerances, and innovate electronics, medical, aerospace, and automotive clients with high reliability.
We have a mission to achieve a new level of speed, precision, and customer satisfaction.
We relocated to a new 8,000 ㎡ facility and began certification for ISO 14001 and IATF 16949. We also holds an independent wastewater discharge permit.
We added six fully automated exposure machines with a total investment of USD 2 million. The maximum etchable metal sheet size expanded to 1.2 m in width and 2.5 m in length, meeting demand for large format metal etching.
We added two more roll-to-roll continuous exposure machines and two etching machines capable of handling materials up to 1200 mm wide, enabling us to mass-produce products measuring 1200 mm by 1500 mm.
We launched the third phase of our R&D and production teams to advance ultra-precision processes and scale production. A roll-to-roll exposure machine was added, supporting materials up to 300 mm wide with ±0.01 mm section accuracy.
As a member of the high-end precision etching supply chain, we invest 5% of our turnover in R&D to optimize our processes.
Added automated etching lines that increased accuracy and capability.
After the plant audit, we became a qualified vendor for Foxconn, Panasonic, Honeywell, LEM, Huawei, Vivo, and OPPO.
Accessed the Apple supply chain, creating a trust track with high global brands.

Any project is initiated by design and a high-attention selection of materials. We have the precision, consistency, and repeatability in our process, starting with the first digital blueprint to the final inspection. Each phase develops out of the previous, making sure that it is reliable every time.
Your drawings are translated by our engineers into the digital blueprint that constructs all etched features in the form of a photographic tool, or CAD file.
We will choose the best metal for your use and clean and prepare the metal for flawless adhesion of the photoresist.
The patterned protective layer is created by the application of a UV-sensitive photoresist to the surface of the metal in a uniform manner.
The phototool exposes the pattern to the ultraviolet light and imparts the photoresist metal to ensure that the pattern is transferred with no additional variation or disregarding exposure.
We then coated the metal so that the unexposed resist is removed, leaving the pattern to be chemically etched.
The controlled etchant bath immerses the workpiece, which selectively removes exposed metal to form the designed geometry and feature detail.
The unused photoresist is removed, and the part is thoroughly cleaned to end up with the final etched surface.
Every component is carefully checked in order to ensure perfection and quality; finishing and packing are done as demanded, and then it is shipped.
Whatever the complexity, our engineers produced your designs with precision and repeatability.
TMNetch is all about quality. All the stages are checked by certified engineers and chemicals to deliver the etched components that are highly accurate and reliable.
We make prototypes within less than 6 hours with a stocked warehouse and a rapid tooling apparatus, minimizing the lead times without compromising the highest level of precision.
We provide services to industries across the globe, from medical to aerospace, with a hassle-free clearance of customs, professional documentation, and assured international delivery.
Our high-tech capability will provide close tolerances, finer details, and thin structures so that there will be repeatability even with the most complicated designs.
We stock the widest range of standard and specialist material types, enabling you to choose the perfect solution for your specific application.
TMNetch engages in long-term relationships with international customers by providing certified solutions, transparent service, and reliable performance each time.
TMNetch has proudly served its clients throughout the United States, England, Germany, Switzerland, Austria, France, Hungary, Israel, Singapore, Vietnam, Malaysia, Thailand, and other countries and has established long-term partnerships with clients based on trust and accuracy.
