Steps conducted at Mifflintown

1. The product is received and stored in our warehouse.
2. The parts are taken from the warehouse and blasted, or if blasting is not required, staged for
   coating.
3. The parts are hung on the conveyor line and washed in our seven stage chemical pretreatment station.
   The stages are as follows:
   
   1st stage: Alkaline Cleaner
   2nd stage: Rinse
   3rd stage: Rinse
   4th stage: Iron Phosphate
   5th stage: Rinse
   6th stage: Rinse
   7th stage: Sealer
    
4. After the pretreatment, the parts enter a dry-off oven to be heated and dried.
5. After the dry-off, a coat of zinc-rich epoxy primer is applied for unmatched corrosion protection.
   This stage is optional, but greatly extends the life of steel products.
6. After the primer is in place, the parts pass through the oven to "gel" the primer.
7. After the primer oven, the parts enter the spray booth and the topcoat color of your choice is
   applied by a combination of automatic and manual touch-up spray guns.
8. The powder then is cured at the powder manufactures specification.
9. After cooling, it is then packaged to prevent scratching and placed in storage.
