Huazhou etching and cleaning machines are specifically designed for pre-treatment degreasing and post-etching resist removal, serving as a reliable supporting system for precision etching processes. By integrating advanced technologies and automated control, they ensure exceptional surface cleanliness, significantly improving etching yield and production efficiency.

Leveraging a deep understanding of the complete etching process chain, Huazhou Machinery has developed this precision system specifically optimized for pre-treatment degreasing and post-etching resist stripping. It ensures that workpieces remain in an optimal surface condition both before and after etching, forming the foundation for high-yield, high-quality production.

Our etching and cleaning machines are engineered to address two critical process challenges:

Before Etching: Thoroughly remove oils, fingerprints, and oxides left from incoming materials, cutting, and handling processes. This creates an absolutely clean and activated metal surface for photoresist or dry film adhesion, fundamentally eliminating pattern defects caused by poor adhesion.

After Etching: Efficiently and gently strip the etched resist layers (ink or dry film) while completely removing residual chemicals and reaction by-products. This delivers a perfect base surface for subsequent passivation, electroplating, or final inspection processes.

Huazhou Technical Advantages — Intelligent, Efficient, and Reliable Cleaning Solutions

1. Process-Driven Customized Design

We do not offer a “one-size-fits-all” cleaning machine. Instead, based on your specific processes—such as metal etching, PCB/FPC manufacturing, and metal nameplate production—as well as workpiece dimensions and capacity requirements, we customize the number of tanks, cleaning methods (ultrasonic, electrolytic, spray, immersion), and drying solutions to ensure perfect alignment between cleaning performance and production line takt time.

2. Advanced Intelligent Control System

Precise Temperature Control: The heating system works in conjunction with sensitive temperature controllers to keep chemical cleaning solutions at their optimal operating temperature, maximizing cleaning efficiency.

Automatic Chemical Dosing & Replenishment: Optional automatic dosing systems monitor and replenish cleaning agent concentration in real time, ensuring process stability while reducing human error and chemical waste.

Multi-Program Adjustability: Multiple cleaning programs can be preset and switched with one click to accommodate different contamination levels or resist types, enabling simple and efficient operation.

3. Superior Manufacturing Quality & Durability

Fully Corrosion-Resistant Structure: The main body and internal chambers are constructed from SUS304/316 stainless steel or high-quality PP/PVC materials, specifically designed to withstand acidic, alkaline, or solvent-based cleaning agents, ensuring long-term stable operation.

High-Efficiency Filtration & Circulation System: Built-in multi-stage filtration keeps the cleaning solution clean for extended periods, prolonging service life and reducing operating costs.

Comprehensive Safety Protection: Equipped with liquid level monitoring, leakage protection, heater dry-burn prevention, emergency stop functions, and other safety features to ensure safe operation.

Applications: Covering the Entire Etching Process Lifecycle

Pre-Etching Treatment: Degreasing, dewaxing, defatting, and micro-etching for metal sheets and stamped parts.

Post-Etching Treatment: Resist stripping, neutralization, and deep ultrasonic cleaning after etching to remove photoresist ink or dry film.

Inter-Process Cleaning: Cleaning between multi-layer etching or special process steps to ensure surface cleanliness and adhesion quality throughout complex manufacturing workflows.

Lay the foundation for perfect etching with every cleaning process.
