What Is Powder Coating?
Powder coating is a process where fine
particles are applied by an electrostatic spray. The powder is
attracted to the object by a grounded negative (cathodic) charge.
The coated items are then baked to cure the powder and can be used
on any part that can be baked at 325ºF to 425ºF degrees.
Powder coats are made with resins such as Polyester, Epoxy,
Polyester Polyurethane and Epoxy Polyester (referred to as hybrids),
each having unique properties and characteristics.
Powder Coating process takes the following steps to complete, and
our plant is equipped with the top of the line technology to fulfill
the customer requirements. Our orders take from one to three
days for the most of our standard orders, and for customized
requests, it may take even more.
1) Loading On Conveyor
- Our 780 foot conveyor
line is where we begin the powder coating process. During this
process, parts are visually checked for damage and rust. Any
findings are then reported to the appropriate supervisors.
2) Pretreatment (All Metals)
Pretreatment is a vital step in the preparation of
metal prior to powder coating. Our high pressure washes include:
- One stage of
multi-purpose iron phosphate at 120ºF
- 180ºF for three minutes.
- Two stages of dionized water for 1½
minutes each stage
- One stage of fresh dionized misting rinse
- This ensures a thoroughly clean and phosphate coated surface
that provides excellent corrosion resistance and powder paint
adhesion on all types of metal products. Our multi-purpose iron
phosphate applies the following coat weights:
- Steel : 50 - 60 mg/ft²
- Aluminum : 5 - 15 mg/ft²
- Galvanized : 15 - 50 mg/ft²
3) Dryoff and Powder Application
- After the parts leave the dionized rinse, they enter a 40
foot dry-off tunnel oven. This extracts all the excess moisture
from the parts. Then they move on to the powder booth. At this
stage, the parts will be applied with the color powder requested
by the customer. With high volume products, we are equipped to
save powder keeping the price competitive.
4) Batch System
- Larger parts are generally powder coated by batch system.
5) Cure Cycle
- Our Powder Coating's suppliers provide us with predetermined
temperature and timing schedules to ensure proper curing in our
gas fired oven. Our 180 foot oven is professionally designed to
cure the products and prevent any chipping of the powder coated
6) Cooling Down, Quality Control and Packaging
- After the parts are cured, a sufficient amount of time is
required for them to cool down. After cooling, the finished
products will be checked by our quality control department for
mil thickness, cure quality, visual color and glossiness of the
finish. When the products pass our quality control inspection,
the final step is water proof packaging and delivering them to
