Comprehensive information compilation of second-hand Japanese Guangchi OTFC-1800 vacuum coating machine:
1、 Core configuration and technical parameters
Vacuum system: The vacuum chamber is made of SUS304 material, with dimensions of either 1550 × 1800mm or 1800 × 1920mm (height differences vary depending on the version); The ultimate vacuum degree is ≤ 7.0 × 10 ⁻⁵ Pa, and it only takes 20 minutes to pump from atmospheric pressure to 1.3 × 10 ⁻³ Pa.
Coating control: Equipped with HOM2-R-VIS350A optical film thickness monitor (wavelength 350-1100nm) and XTC/3+6-point quartz crystal sensor.
Evaporation source and ion source: Equipped with dual electron guns and a 23cm RF ion source, supporting mass production of high-performance optical filters.
Working conditions: Three phase 200V/50-60Hz power supply (approximately 120KVA), water flow rate ≥ 180L/min, and air pressure ≥ 0.5MPa are required
2、 Current situation of the second-hand market
Price range: 380000 to 650000 yuan, depending on the equipment year, configuration, and whether installation warranty is included
Basic payment of approximately 380000 yuan (quoted in 2025);
The quotation for the quasi new machine including ion source and installation services is 480000-650000 yuan;
Batch procurement (≥ 5 units) can be reduced to 258000 yuan per unit.
Distribution channels: mainly traded in Dongguan, Tianjin and other places, with most sellers providing installation, debugging and process guidance services.
3、 Typical application scenarios
Specially designed for the production of infrared cut-off filters, color separation filters, and laser protection films, supporting high-precision coating of over 100 layers, and compatible with planetary or bell shaped workpiece racks (diameter 1400-1600mm).
4、 Maintenance and Fault Prevention
Maintenance points:
Regularly clean the vacuum chamber and target area, and replace the vacuum pump oil;
Check the sealing of electrical circuits and calibrate the film thickness monitoring instrument;
Lubricate the rotating frame components and replace the O-ring seals in a timely manner.
Common faults: Decreased vacuum degree (damaged rubber ring/aging pump oil), insufficient film strength (substrate contamination), motor tripping (rotor corrosion), etc.
5、 Purchase suggestions
Priority should be given to equipment that comes with a one-year warranty, original optical control, and RF ion source. The focus should be on verifying:
Integrity of vacuum pump assembly (mechanical pump+diffusion pump+Polycold);
Substrate heating capacity (up to 350 ℃) and uniformity;
Is there a historical record of coating quality.
Note: The price is greatly affected by configuration differences (such as ion source size, cryogenic device) and transaction channels. It is recommended to conduct on-site machine inspections and request process testing reports
