3 Common Mistakes to Avoid in Powder Coating
At UK Powder Coating we take every precaution to give you a perfect powder coat every time. We’ve seen our fair share of powder coating mishaps and so have put together this handy guide on what not to do.
Inclusions are small particles of dust, bits of fluff, and other lint that is visible on the surface of the part. Generally, this is caused by incomplete preparation work and sometimes a dusty coating environment. Always ensure that any part you want to powder coat is properly cleansed of all dirt, grease, and lint before you start applying any powder.
This is either a problem with the spray gun or the operator. The process of applying an even coat by hand requires focus and attention to detail, as well as a high-quality spray gun. Some spray guns, if not properly set up, can have a build up of powder in the tip and ‘surge’ all at once, leaving one area much thicker than elsewhere.
This mistake is when the item isn’t heat treated long enough to properly cure the powder. However, it can be very difficult to spot. The first sign of under curing is an overly glossy finish to the powder coat. Additionally, a crude way of checking if a coating is properly cured is to hit and insignificant part with a hammer or screwdriver. If the paint becomes damaged or chips away, then you have a problem.
With this in mind, UK Powder Coating Services have taken the guess work out of this process. Last year we invested in a state-of-the-art Gema paint line that has a computer automated system to ensure every product turns out beautifully.
