Chemical Etching Machine Manufacturer
Industrial Chemical Etching Machines for PCB and Metal Manufacturing
Quick answer: A chemical etching machine is an industrial system that uses sprayed etchant (ferric chloride, cupric chloride, or alkaline chemistry) to selectively dissolve exposed areas of a metal sheet or PCB, producing burr-free, stress-free parts with 25-200 microns line/space resolution. Golden Eagle has manufactured conveyorised spray etching machines for over 20 years in Beijing, China, shipping to 30+ countries with CE certification.
Common applications include PCB manufacturing, flexible circuits (FPC), lead frames, RFID antennas, stainless steel nameplates, decorative panels, filter mesh, and cutting dies.

Read article →Frequently Asked Questions
What is a chemical etching machine?
A chemical etching machine is precision industrial equipment that uses chemical solutions to selectively remove material from metal sheets or PCBs, creating intricate patterns and circuits. It employs spray technology to achieve uniform, high-precision etching across the workpiece surface.
What materials can an etching machine process?
Etching machines can process various metals including stainless steel, copper, brass, aluminum, zinc, magnesium and titanium. Different etchants are used for specific materials to achieve optimal precision and results.
How do I choose the right etching machine?
Consider these factors: (1) material type and thickness, (2) required precision and line resolution, (3) production volume, (4) available floor space, and (5) budget. Our engineers can help specify the optimal machine for your application.
What is the price range of etching machines?
Prices vary by size, automation level and specification. Entry-level machines start around $5,000, while fully automated industrial systems range from $8,500 to $50,000+. Contact us for a customized quotation based on your requirements.
Do you offer installation and technical training?
Yes. We provide one-stop service including equipment installation, debugging, process parameter setup and operator training. Our technical team is available to support customers worldwide.
What is the typical etch rate on a conveyor etching machine?
Conveyor spray etching machines typically achieve 25-50 microns per minute on copper with cupric chloride chemistry, and 15-30 microns per minute on stainless steel with ferric chloride. Modern conveyor lines hold plus or minus 5 percent uniformity across the chamber width through oscillating spray headers and baffle-controlled flow.
What line/space resolution can a chemical etching machine achieve?
Production line/space resolution on a conveyorized spray etcher is typically 50-100 microns for PCB (cupric chloride) and 100-200 microns for metal (ferric chloride). With fine-grain photoresist and optimized chemistry, 25 micron line/space is achievable for flexible PCB and thin foil.
What is the difference between spray etching and immersion etching?
Spray etching uses pumped nozzles to deliver fresh etchant at high velocity to the workpiece, giving faster etch rate, better side-wall profile, and lower chemical consumption. Immersion etching submerges parts in a bath — slower, more isotropic, but better for delicate 3D parts and small batches.
How long does it take to deliver a custom etching line?
A standard conveyor etching machine ships in 30-60 days from order. A full custom PCB etching line with pre-treatment, post-treatment, and wastewater treatment takes 90-150 days including installation, commissioning, and operator training. Containerized turnkey lines for export typically leave the factory 75-90 days after PO.
Do your etching machines meet CE standards?
Yes. All Golden Eagle etching machines are CE-marked for European markets and manufactured under documented quality-controlled processes. The machines comply with EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Every unit is fully factory-tested before shipment — including etching chemistry, temperature control, conveyor speed, spray uniformity, and electrical safety. Documentation package includes Declaration of Conformity, CE Technical File, factory test reports, and full operation manual.
What warranty and after-sales support do you provide?
Standard warranty is 12 months from commissioning or 18 months from shipment, whichever comes first. Lifetime remote technical support is included. On-site service engineers are available within 72 hours for customers in Asia, and within 5 working days for Europe and the Americas. Spare parts ship from Beijing within 24 hours.
Can your etching machines integrate with an existing production line?
Yes. Golden Eagle etching machines are designed for line integration. Standard interfaces include 24V I/O for PLC handshaking, Modbus TCP and Profinet for SCADA connectivity, and 4-20 mA analog signals for legacy systems. We provide mechanical interface drawings and I/O maps for in-house engineering teams, or turnkey integration by our field engineers.
