The PVA 750 can be fitted with up to three spray valves which can spray different widths of coating with or without air atomisation.
PVA's needle valve is very effective for obtaining precise edge definition around components that must not be coated, such as connectors.
Many companies still use dipping or hand spraying techniques for applying conformal coatings.
The PVA machine gives much better economy in the use of coating material, eliminates all masking and brings consistency and repeatability to the coating process.
There are also significant health and safety benefits, as the machine cabinet is fully enclosed and extracted.
Inline systems for higher volumes are available with curing tunnels, inverters and linking conveyors.
