The coating industry has extremely high requirements for the vacuum environment and film quality. Traditional oil-lubricated vacuum pumps generate oil mist during operation, posing a risk of contaminating the vacuum chamber and affecting film adhesion and uniformity. They also require regular oil changes and maintenance, affecting continuous production. Leynow oil-free vacuum pumps adopt an oil-free lubrication structure to prevent oil contamination from entering the vacuum system from the source, and have become the preferred configuration for multiple processes such as magnetron sputtering, vacuum evaporation, PVD/CVD coating, optical coating, and coating line vacuum maintenance.
Challenges Faced by the Industry
The requirements of coating production for vacuum systems are not just about "pulling a vacuum", but more importantly, high cleanliness, high ultimate vacuum, and stable repeatability. In practical applications, customers often encounter the following types of problems:
Risk of Oil Contamination
Oil-lubricated vacuum pumps generate oil mist during exhaust, which may contaminate the vacuum chamber, targets, and workpiece surfaces, affecting film adhesion and uniformity.
Insufficient Ultimate Vacuum and Pumping Speed
Coating processes have high requirements for ultimate vacuum and pumping speed. Insufficient pumping speed will prolong the vacuum pumping time and affect coating efficiency and film quality.
Unstable Continuous Operation
Coating production lines often require 24-hour continuous operation. Pump body overheating or vacuum fluctuations will directly affect film consistency and equipment lifespan.
High Maintenance Costs
Vacuum pump oil needs to be replaced regularly. Under working conditions containing coating by-products, the oil is prone to deterioration, and downtime for maintenance affects overall production efficiency.
Leynow Coating Industry Solutions
Targeting the actual working conditions of the coating industry, Leynow provides overall vacuum solutions centered on oil-free vacuum pumps, forming a complete service closed loop from equipment selection and installation and commissioning to post-maintenance.
Clean and Oil-free Vacuum Acquisition Method
Oil-free vacuum pumps adopt a self-lubricating structure, and the inner wall of the cylinder is specially treated. They do not generate oil mist or exhaust gas, preventing lubricating oil from entering the vacuum system, meeting the high cleanliness requirements of coating processes for chambers and film layers.
Selection Solutions Matched to Coating Processes
Based on the coating method, chamber volume, ultimate vacuum requirements, and pumping speed requirements, professional engineers provide selection suggestions to avoid efficiency and lifespan issues caused by "using a large pump for a small job" or "overloading a small pump".
Guarantee of Stable and Continuous Operation
For coating production lines operating continuously for 24 hours, the heat dissipation and anti-corrosion structures are optimized to reduce the risks of pump body overheating and by-product deposition, maintain stable vacuum degree output, and ensure film consistency and yield.
Full-cycle Service and Parts Guarantee
Providing installation and commissioning, regular follow-up visits, and maintenance contract services. Repair parts are Leynow original genuine parts. All repair projects come with a 12-month warranty to reduce unplanned downtime.
