MP 30M-AP – Mobile Atmospheric Plasma Spray System

The GST MP 30M-AP Mobile APS System is a compact, fully integrated atmospheric plasma spraying solution designed for high-quality coating applications in both field service environments and industrial workshop facilities.

Its key advantage is the integration of all essential system components into a single industrial-grade mobile enclosure, including the process control cabinet, gas supply and regulation system, and power distribution module. This monoblock design significantly simplifies installation, reduces commissioning time, and provides outstanding mobility without compromising coating performance, reliability, or process control.

The MP 30M-AP features an open and flexible control architecture, allowing seamless integration into automated robotic coating lines. Depending on customer requirements, the system can be expanded with a complete range of peripheral equipment, including:

• Industrial robots
• Workpiece positioning systems
• Soundproof spray booths
• Ventilation and filtration systems
• Additional process monitoring equipment

The modular design enables the system to be configured as a mobile manual workstation or upgraded into a fully automated plasma coating cell capable of meeting the requirements of advanced industrial production.

Main System Features

• Closed-loop mass flow control system for accurate regulation of all process gases
• Remote access module for efficient diagnostics, maintenance, and technical support
• Advanced PLC-based control platform ensuring precise and reliable process management
• Intuitive graphical touchscreen HMI for easy operation, parameter adjustment, and real-time monitoring
• Comprehensive process data acquisition, visualization, and reporting functions
• Multi-level password-protected user access management
• Complete process data recording for full coating process traceability and analysis
• Advanced Software Platform

The advanced software platform of the MP 30M-AP provides intuitive system operation, complete process transparency, and stable long-term performance. All critical operating parameters are continuously monitored and displayed in real time, ensuring precise control of the plasma spraying process and maintaining consistent coating quality.

The software architecture has been designed for future expansion and supports integration of additional plasma torches beyond the standard system configuration.

Each supported plasma torch has predefined operating limits and approved parameter ranges stored within the control system. This intelligent protection function prevents operation outside validated conditions, improving:

• Process reliability
• Equipment safety
• Coating repeatability
• Overall system efficiency

Process Cabinet

The process cabinet integrates the primary functional modules of the APS system, including:

• Gas supply and regulation module
• Process control and distribution module
• Electrical control module

The cabinet is mounted on a mobile platform, allowing convenient transportation and flexible deployment in both production facilities and field operation environments. The compact mobile design provides maximum installation flexibility while maintaining industrial-grade protection and reliability.

Gas Supply Module

The gas module is a critical subsystem responsible for the precise supply, regulation, and monitoring of plasma-forming and carrier gases required for plasma generation and powder transportation.

• Stable gas control directly affects:
• Plasma arc stability
• Process repeatability
• Coating quality
• Overall system performance

The gas module includes:

• Closed-loop plasma gas flow regulation using high-precision mass flow controllers
• Safety valves and gas monitoring instrumentation
• Dedicated supply circuits for:
• Argon (Ar)
• Hydrogen (H₂)
• Nitrogen (N₂)
• Digital pressure monitoring sensors
• Pressure regulators
• Check valves
• Pressure gauges installed on each gas line
• Gas flow calibration interface
• Integrated gas filtration system

Control and Distribution Module

The control and distribution module provides the connection interface between the process cabinet and the plasma torch. It manages all essential process systems, including:

• Plasma-forming gas supply circuits
• High-voltage ignition system
• Plasma torch cooling-water circulation system
• Auxiliary process connections

The optimized design ensures reliable operation, simplified maintenance, and stable plasma generation.

Electrical Control Module

The electrical module contains the PLC-based hardware and software responsible for controlling and coordinating all APS system functions. All critical process parameters are managed through closed-loop control algorithms, ensuring:

• Maximum process stability
• High repeatability
• Reliable coating performance
• Safe system operation

The electrical module includes multiple communication and I/O interfaces for integration with external equipment and auxiliary systems, including:

• Industrial robots and automation platforms
• Cooling units and heat exchangers
• Dust extraction and filtration systems
• Additional peripheral equipment

For enhanced operational safety, the electrical compartment is completely isolated from gas supply components. A controlled positive air pressure is maintained inside the electrical enclosure to prevent the accumulation of combustible gases in case of leakage. A differential pressure monitoring system continuously supervises cabinet pressure and automatically activates protective measures when required.
