About
Precision chemical etching and PCB production equipment — from one Shenzhen partner
WET etched is the brand of Shenzhen Xinxin Precision Equipment Co., Ltd., based in Longgang District, Shenzhen. We combine an in-house precision metal etching workshop with an engineering team that builds and supplies wet-process and PCB manufacturing equipment, plus a fast-moving stock of spare parts for PCB drilling and routing machines.
Because we run the same processes we sell, our advice is practical: we know what an etching line needs to hold tolerance shift after shift, and which spare parts keep a drilling room running.
- Factory-direct — engineering, production and support under one roof
- Etching services, complete equipment and spare parts from a single supplier
- OEM / ODM accepted, worldwide express and sea freight from Shenzhen
Three ways we support your production
Whether you need finished etched parts, a new production line or a replacement part tomorrow, you deal with the same engineering team.
Precision Chemical Etching
Photochemical machining of stainless steel, copper, brass, nickel, titanium, molybdenum, Kovar, Invar and more — burr-free, stress-free parts such as meshes, shims, springs, shields, lead frames and encoder discs.
Etching solutions →Production Equipment
Etching, developing, stripping, plating, cleaning and surface-finishing lines, exposure and imaging systems, CNC drilling and routing machines, inspection and automation — configured to your panel size and throughput.
Browse equipment →PCB Machine Spare Parts
Collets, air-bearing spindles and shafts, pressure feet and brushes, cylinders, sensors, tool magazines, drill and router bits and backup boards for Hitachi, Schmoll, Excellon, Westwind, Posalux and other machines.
Browse accessories →One workshop, every finishing step
Keeping etching, cutting and machining together shortens lead times and lets us control quality from the first sheet to the final inspection.
Precision Chemical Etching
Our 50-meter etching line handles projects of varying scales while holding fine features and tight tolerances on complex, detailed components.
Precision Laser Machining
Five laser cutting machines execute intricate cuts quickly and accurately, from prototypes to large-scale production.
CNC Machining
CNC machining is the cornerstone of our operations, producing components with tight tolerances and consistent quality for complex parts and volume orders.
CNC Punching
Efficient punching across a wide range of materials, with every component checked against the specification on your drawing.
CNC Grinding
Grinding delivers the final surface finish and precise dimensions required for demanding assemblies.
State-of-the-Art Facilities
A dedicated CNC floor alongside the etching and laser lines lets us run multi-process parts without outsourcing.
From inquiry to delivery
Inquiry & review
Send a drawing, specification, part number or photo. An engineer reviews feasibility, material and tolerances.
Proposal & quote
You receive a clear quotation with configuration, lead time and trade terms. Samples can be arranged.
Production & QC
Parts are produced and inspected in-house; machines are assembled and tested before they leave the factory.
Shipping & support
Spares usually ship in 2–3 working days, machines in about 10–15 working days, followed by technical support.
