The billet is crushed against the die until it has no place else to go, and it begins to squeeze out through the die to emerge on the other side as a fully formed profile.
Some presses extrude slowly, at one or two feet per minute; a softer alloy taking on a very simple shape may be extruded at a rate of feet per minute or even faster. The coating system includes a three-stage pretreatment system that starts with a cleaner, a reverse osmosis rinse and an adhesion promoter composed of chemicals supplied by Bulk Chemicals BCI.
The parts are then hung and coated with an Axalta line of powder coatings. Keller ran the Benada coating line for almost five years before moving to the master scheduling department, but he says his heart remains in extrusion coating.
It is an area that receives a lot of attention from company officials because of warranty and quality issues.
For example, each hour, an experienced staff member tests the adhesion and curing of the coated extrusions, allowing Benada and the coating team to respond quickly if a problem is discovered so that necessary adjustments can be made. We look at our cleaning and our tanks, and we take it very seriously, because our customers depend on it from us. The quality control includes the hourly tests as well as hourly titration checks of chemicals.
The BDACS single-stage chemical process controllers or multi-stage chemical process-control systems are capable of real-time process control and monitoring; data trending and performance tracking; process conditions using the parts-tracking module; alarm notifications; realtime and archived data analytical tools; and custom reports based on jobs run, among other features.
Keller says the acquisition system has made fine-tuning the pretreatment process a much simpler endeavor. While Keller says the system is set up to reduce human error on the front end, there is also a stepped up effort for quality control testing on the back end when the parts are powder-coated. He says that the testing is not a requirement from Benada customers, but that it is a way to make sure a product leaves the plant exactly as it was ordered.
We used to prep a day in advance if we needed to change colors, but now we can do up to six color changes in a day and not feel a delay. Marki says the newer powder coating equipment and advanced chemistry system have been extremely helpful in filling orders for customers, especially with a surge in seasonal demands, such as with patio furniture, windows and enclosed pools. We have a lot of room still. For more information, visit benada. Question: What methods are available for removing cured powder coatings, and what are the pros and cons of these methods?
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process.
