In high-end vacuum heat treatment, plasma nitriding, and Physical Vapor Deposition (PVD), the stability of the electrical power source determines the final quality of the surface layer. Standard direct current (DC) power supplies often suffer from unstable plasma discharge, slow energy transfer, and a high risk of electric arc burns that can destroy delicate, expensive molds.
To solve these technical bottlenecks, Jiangsu Juchuang Automation Technology Co., Ltd. engineered the Ultra-High Power High-Frequency Pulsed Plasma Generator. Backed by our proprietary intellectual property, this next-generation power supply instantly elevates voltage and current to peak values, massively boosting gas ionization rates inside vacuum chambers. It represents the ultimate high-energy engine for advanced material modification and high-speed tool coating.
1. Three Pillars of Power and Efficiency
Our high-frequency pulsed plasma technology completely transforms traditional vacuum processing through three core operational advantages:
An Efficiency Revolution
By delivering highly energetic, concentrated pulses, the generator accelerates chemical diffusion at the atomic scale. This shortens the core active nitriding process phase to just 1 to 2 hours (excluding standard chamber heating and cooling cycles). This major speed upgrade cuts down electricity consumption and reduces your workshop's overall operating costs.
Exceptional Performance
The high ionization rate pushes active nitrogen atoms deeper and faster into the steel matrix. This builds an ultra-dense, uniform compound layer with a deep diffusion case depth exceeding 100 micrometers (um). Your workpieces gain outstanding resistance to mechanical wear, cyclic fatigue, and aggressive corrosion.
Absolute Processing Safety
To prevent localized arc discharges from damaging expensive molds, our power supply features an ultra-fast digital monitoring unit. The system detects anomalies and suppresses electric arcs in less than 20 nanoseconds (ns). This lightning-fast response completely eliminates the risk of arc burns, protecting delicate mold edges and guaranteeing a high batch yield.
2. Advanced Digital Control and Arc Suppression
At the core of Juchuang's pulsed generator is a high-speed digital controller running at a 100 MHz sampling frequency. It supports precise, real-time control across three critical operating phases:
-
Arc Checking Energy (E0): Continuous tracking of the discharge voltage and current to catch the earliest signs of glow-to-arc transition.
-
Arc Action Energy (E1): The instant detection window where the system registers a true micro-arc event.
-
Arc Suppression Energy (E2): The immediate shutdown and energy dissipation cycle.
This smart energy management ensures the maximum pulse power time remains under 100 nanoseconds (ns), generating an exceptionally stable rectangular wave. This prevents energy spikes and maintains a smooth, continuous plasma glow throughout the entire processing cycle.
3. Scalable Stacked Output Architecture
For massive industrial operations—such as treating heavy aerospace gears or 45-ton stamping dies—a single power source is not enough. Our system is built with a highly integrated, modular cabinet layout that supports stacked parallel outputs, as diagrammed in image_0043d8.png:
-
Up to 8 Stacked Modules: Customers can connect up to 8 generator power supplies in parallel to match the volume and loading requirements of ultra-large vacuum chambers.
-
Intelligent Master-Slave Control: When modules are linked, operators only need to set parameters on the Master control terminal. The system automatically configures and syncs all connected Slave units.
-
Automatic Synchronized Arc Response: In a stacked configuration, the parallel bus synchronizes arc protection across all modules. If one unit detects an arc event, the entire network reacts simultaneously to protect the workpieces.
-
Dynamic Power Allocation: The system automatically scales the active power units up or down depending on real-time vacuum conditions and load surface area, ensuring peak energy utilization and long hardware life.
