The Powdercoating Process
Powdercoating is a relatively new metal coating technique and was first introduced to North America in the early 1970’s. In this process, powdered Expoxy- Polyester or Polyurethane resins along with coloured pigments are applied to metal products using an electro-static charge. The product is then “ baked” in a high temperature oven causing the powder to melt, flow , and then cure , forming a molecular fusion bond. The result is a surface – to- coating bond unlike any other.
The Five Steps Powdercoating Tour
Step 1: Product Arrives at ABC’s Plant
Unloading occurs within out drive-in bay. Products are individually placed onto custom metal tooling that is attracted to an overhead conveyor system. From here they move forward into our Cleaning Station.
NOTE: All tooling is designed and manufactured in house.
Step 2: Clean as a Whistle
Still attached to the conveyor, your product passes through an extensive chemical cleaning system of 7 or 5 stages, depending on the substrate. Both include a final deionized rinse. This pre=treatment ensures a clean phosphate an etched substrate for coating. This is one of the most critical steps in high quality powdercoating. After leaving the final deionized rinse the product travels through a separate dry off oven. This allows us to control the temperature to ensure properly dried parts and to prevent the overheating of difficult parts such as zinc and aluminum die casting.
Step 3: Powder Meets Metal
After cooling down, your pre-treated product passes through one of our applicator booths. Here the powder is evenly applied to the surface, either by one of our highly trained technicians or with our automatic reciprocators. Excess powder is contained by the booth and continuously recycled.
Step 4: Getting Baked
Your product is transported through our infra red preheat section and then forward into our highly temperature oven, causing the powder to melt, flow and cure leaving an incredibly durable and attractive finish second to none.
Step 5: Cool Down Inspection and Return to Sender
The items are now allowed to cool to complete the process. Once cooled, each item is individually inspected and carefully re- packed in our customer’s containers and sent back to our satisfied clients.
