Maintaining bead size and charge in stirred mills enhances grinding efficiency, crucial for producing consistent particle sizes in coatings formulations.
Conventional plastic finishing methods often require people to handle each part before and after it is coated, which increases labor costs. Additionally, while coating material costs are relatively low, the large amount of waste from overspray increases the amount of coating required to complete the finishing process and can dramatically reduce profitability. Recently, a new tumble spraying system* was developed to eliminate these parts coating issues and help manufacturers of plastic products regain their competitive edge.
