Equipment Overview

This water-based stencil cleaning machine is mainly used for cleaning SMT stencils in the electronics industry with water-based cleaning liquids. It adopts the most advanced cleaning process in the industry to achieve 100% cleanliness and environmental protection. The machine consists of a cleaning system, rinsing system, drying system, and filtration system. Using electricity and compressed air as energy, the stencil is manually placed into the cleaning chamber. After setting the cleaning, rinsing, drying, and other related parameters on the touchscreen, pressing the start button will automatically clean, rinse, and dry the stencil. When the set cleaning process is completed, it stops running and resets automatically for the next workflow. This machine is very convenient for operators to clean stencils, greatly improving production efficiency and quality. It belongs to a new type of high-performance fully automatic cleaning equipment. The equipment uses water-based liquid cleaning agents and DI water for rinsing, with no safety hazards and no harm to personnel.

Product Features

1. High-pressure spraying system specially designed for cleaning stencils, misprinted boards, PCB/PCBA, etc., with water-based cleaning liquids.

2. Dual liquid tanks with heating systems to meet cleaning, rinsing, and hot air drying needs.

3. Process flow: Cleaning - chemical isolation - rinsing (open/closed loop) - drying.

4. Equipped with advanced fully automatic touchscreen operation software for easy program file saving and use.

5. System counting function automatically accumulates the number of cleaned stencils and cycle filtration times.

6. Liquid and pump pressure are displayed on the panel pressure gauge to promptly reflect equipment operation status.

7. Spraying pressure is monitored by a pressure sensor, and an alarm will sound if the set pressure range is exceeded.
