What happens here

The internal orifice of a paint sprayer tip is made of a durable carbide material, but it is subject to wear during use. Manufacturer studies indicate that a 515 tip can degrade to the equivalent of a 517 tip after spraying approximately 20 gallons of paint. This wear continues, with the same tip potentially becoming a 519 tip after 60 to 80 gallons. This rapid enlargement of the orifice in the initial stages of use, followed by a tapering off, significantly changes the spray pattern from its original design.

Goal: Learn about the internal construction of paint sprayer tips, specifically the carbide orifice, and how it naturally wears down over time, leading to an enlarged opening and altered spray patterns.

What they say

Hide

inside of a tip, it's got a carbide material, the little orifice right there. And we talked to one of the major manufacturers that manufactures these tips. They did some studies on these tips. And with a lot of different paints and products in all the tips across the board, at about 20 gallons, a 515 tip became a 517 tip. And that was pretty standard with all the tips. So, what this is telling you is the Orphice is getting bigger really fast. So after 20 gallons, a 515 is now a 517. And so it was rapidly wearing the tip out and then it kind of started to taper off, you know, and didn't wear it out as fast. But after about I think it was somewhere around 60 to 80 gallons, it was like a 519 tip. So that orifice is getting bigger and it's changing the pattern of the the spray pattern of the tip. Right.
