Mifflin Powder Coating
We provide high quality powder coating services for businesses and individuals. Affordable prices at the highest quality. Our curing oven measures 18 feet long, and our pre-treatment process of sandblasting and chemical cleaning ensures industry-best quality.
Pre-treatment
Pressure Washing
A combination of heat and diluted phosphate cleaner ensures that all dirt and grease is removed from the metal before coating. The phosphate also creates a bonding layer to increase the adhesion and durability of the coat.
Sand Blasting
Sandblasting is the ultimate pre-treatment measure. Our powerful DB500 XL sandblaster can remove anything, from rust and mill scale to old paint coats. Blasting also increases the surface area of the parts, which maximizes the adhesion and durability of the coat.
Coating
Application
The powder is applied using a GEMA applicator, which has industry-best technology. The electrostatic charge can be adjusted for different shapes of metal, to ensure that the coat is even across the entire item.
Curing
The item is baked in a large oven to cure. The powder melts and bonds to the metal, becoming hard and durable. This the the part of the process where the most can go wrong. Too much heat can cause the powder to become brittle and crack, and too little heat will leave the powder uncured and flimsy. Our convection oven is temperature controlled very accurately to avoid this issues.
Finished Product
Finished Parts
The parts are packaged carefully to ensure they are not damaged in transit. We offer pickup and delivery service up to 1 hour away.
Quality Testing
The black sample above shows a successful salt spray test. The coat is scratched down to the metal, and saltwater is sprayed onto the part for 500 hrs, or about 21 days. If the rusting spreads across the surface, then the test fails. A high quality coat will look like the one pictured, where the rust does not spread from the score in the coat.
