Vacuum deposition installations are widely used for applying optical, protective, decorative and hardening coatings. Many enterprises continue to operate installations of the VU-1A, VU-2M, VU-700D, VU-1B, VU-1100 models and other systems created to solve complex technological problems. With timely maintenance, such equipment remains highly efficient, but over time it requires modernization of control systems, restoration of vacuum tightness and repair of pumping equipment.
The company Technologies and Proposals LLC carries out modernization and repair of vacuum spraying installations, preserving the technological capabilities of existing equipment and adapting it to modern production requirements. This approach can significantly reduce costs compared to purchasing a new installation and at the same time increase the stability of technological processes.
Modernization of control systems for vacuum deposition installations
One of the most popular areas is the modernization of power and control racks. Replacing outdated relay and analog circuits with modern programmable controllers provides automatic control of all stages of the vacuum deposition process.
After modernization, vacuum spraying installations can be used to apply:
- optical coatings;
- protective and decorative coatings;
- hardening coatings;
- multilayer functional coatings.
Automation allows precise control of vacuum, substrate temperature, composition of the working atmosphere and parameters of sputtering sources, ensuring high repeatability of results.
Modernization of technological capabilities
Specialists of Technologies and Proposals LLC are upgrading vacuum deposition installations to operate in combined plasma flows and apply coatings based on solid solutions. Such technologies make it possible to obtain coatings with increased hardness, heat resistance and wear resistance and are in demand in tool production, mechanical engineering and instrument making.
Repair of vacuum systems and pumping equipment
The quality of coatings directly depends on the condition of the high-vacuum and forevacuum pumping systems. Reduced pump performance or leaks lead to deterioration of process parameters.
Technologies and Proposals LLC performs:
- repair of double-rotor pumps DVN-50;
- repair of rotary vane pumps NVR-16D and NVR-25D;
- repair of vacuum gauges VT-1-4 and VMB-1;
- repair and replacement of vacuum equipment;
- recovery
