Product Application
This equipment processes precision curved and irregular workpieces to conduct surface cleaning, molecular activation and micro-etching. It thoroughly resolves common production issues including poor adhesion, glue delamination and ink peeling.
It serves as essential pre-treatment equipment for various sectors: semiconductor packaging, 3C electronics, touch panels, LED encapsulation, automotive parts, new energy lithium batteries, plastic, metal and glass materials.
Equipment Structure
The open-air direct jet plasma surface treatment system consists of three core parts: power supply unit, direct jet plasma spray gun and control module.
1. Power Generator
It supports automatic power matching to deliver stable, high-precision output without being disturbed by air pressure fluctuations. Operators can adjust all operating parameters according to the actual working state of samples for ideal processing performance.
2. Direct-Spray Plasma Gun
Designed for tiny, intricately shaped workpieces, this gun delivers a treatment width ranging from 2mm to 6mm. It can be integrated with existing production lines to enable fully automatic inline processing and cut labor expenses.
3. Control System
Housed inside the power supply main unit, this module governs the whole operation of the atmospheric plasma cleaner and provides full-system safety protection.
