HVLP Paint Sprayer Specification Example for Three-Wheelers: Long Life Version
HVLP Paint Sprayer Specification Example for Three-Wheelers: Long Life Version
This is a worked specification for hvlp paint sprayer in a long life version programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.
The long life version version exists because the duty cycle on three-wheelers is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually lead time that slipped twice before bulk started.
