Hand spraying is a skilled trade that is becoming obsolete due to advances in technology. Most notably, robotics have taken over a large portion of spray applications from their human counterparts in the liquid coatings industry.
As the technology becomes more and more popular, the need for a skilled human becomes less and less. However, regardless of advances in technology, there will still be a need for hand sprayers in liquid coating applications for a few different reasons.
The DECC Company is an almost exclusively rack-spray facility. During the coating process, components never touch…they are all sprayed and cured on their own hook. The only time they touch is during the packing process, and that is only if the customer requires a bulk pack.
Dip-Spin vs Rack-Spray
What this means is that compared to a dip-spin, bulk application process, parts coated in a rack-spray process will have a much more uniform and quality finish. The necessity of 100% sorting is eliminated. However, the most important distinguishing factor is that fallout from the coating process is almost nothing where dip-spin can yield upwards of 20% defective parts each run.
Although pricing for a bulk, dip-spin process may be enticing on paper, the total processing cost for certain part geometries that don’t lend themselves to a bulk application tends to be higher than a rack-spray price.
