Electrocoating: Understanding How It Really Works

April 13, 2018

Electrocoating technology is usually described in a vague manner. That's just the way experts think. They describe the electrical charge, the vat full of paint, and the post-process rinse tank. What if someone needs more details? In that case, clarification is required. How does the process really work? Well, it all begins with the pretreatment room, a series of operations that assures the establishment of a paint-attracting electrical charge.

Improving Uniform Transfer Efficiency of Powder Coating Guns

March 29, 2018

Electrostatic spray guns rely on a delicate balance. Pressure variables and particulate flow rates dominate that relationship. Check out the tubes entering the handle. There's a powder feed line there, plus an electrical cable. An air compressor hose is in the mix, too. As the gun is triggered, pressurized air fires the balanced powder load towards a grounded workpiece. Measured in terms of uniform transfer efficiency, the system is in a state of equilibrium.

What is Batch System in Powder Coating?

March 20, 2018

Production lines are complicated beasts. In an ideal world, a line of products zips through the factory, one at a time, before arriving at the finishing room. But this isn't an ideal world, and that approach, well, it can be slow. What if the shop, a powder coating shop, uses a batch processing system instead of this linear mode of operation? Let's check out that group or stack treatment method.

Early Signs of Powder Equipment Fatigue and Breakdown

February 28, 2018

Troubleshooting guides are tough to master. The operator follows repair procedures, or maybe the entire team adopts a trial-and-error approach. Either way, the process is usually gruelling. For that reason, we're going to make it a little easier to follow. Let's test out that straightforward approach path on this powder coating problem. The equipment is breaking down, the repairs are costing the company a fortune, and we need solutions.

Cost Effectiveness of Choosing Powder Coat versus Wet Paint

February 14, 2018

If you've got a fabrication job where longevity and durability are paramount, you likely will want to have the right finish for your product. Whether you are creating kitchen equipment or HVAC gear, or likely something in between, quality and durability are going to be aspects you focus on. This leads us to look at powder coating vs wet paint as a finish for your product.

Heat Tolerance of Powder Coating: How Much Can It Take?

January 30, 2018

Powder coating work relies on procedural mastery. One stage leads inexorably to the next, so start with the prep work. Cleaned and prepped, the electrostatic coating phase is initiated, then the workpiece enters the curing oven. On top of those systematically regulated operations, there are critical processing tolerances to address. Do you see an example of tight-gap process control? We can, right there in the curing oven.

Powder Coating Aluminium Extrusions

January 15, 2018

Amongst the many aluminium extrusion finishing methods, powder coating technology is recognized as the superior solution. Pick up a pair of safety goggles and watch the intricately profiled objects pass through the powder treatment booth. Even though those long rods have a complex cross-sectional core, the coating medium somehow finds its way into every crevice and sharp turn. Let's restart the equipment and really examine the process.
