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.

A good amount of commercial food grade processing equipment comes “out of the box” with non-stick, FDA acceptable coatings applied to the appropriate machine mechanisms (learn why we say “FDA acceptable” and not “FDA approved” here).
As is with all new purchases, everything works great for a period of time. However, food ingredients can be surprisingly abrasive or acidic and coatings are not impermeable to wear, even the most robust ones.
Conversely, when the equipment does not come with a coating and sticking ingredients start impeding production for extended periods of time for cleaning, it is determined only after processing that one is needed.
In both instances, it is probably more cost effective to contact a local coating applicator to apply an FDA acceptable coating than it would be to contact the manufacturer for a replacement component or to have them locate an applicator.
However, it should be noted that there is no one cookie cutter FDA acceptable coating (no pun intended) that can solve every issue.

Ideally, today’s digital welding equipment can be fine-tuned to the point of producing almost zero spatter and weld engineers and technicians can lay a beautiful weld at the start of production with brand new equipment.
However, in a real world production setting, weld variables rarely stay tuned to a laboratory type setting. Weld fixtures become misaligned. Component tolerances vary over time. Weld equipment becomes worn. Weld variables change with every new trouble shooting attempt. Ultimately, these all contribute to the buildup of weld spatter.
There are multiple solutions to preventing mig weld spatter from building up and causing quality or productivity issues in your high volume welding environment.

When a manufacturing design engineer is developing a component, they are designing it to perform as intended in the field. Failure is not planned for because if there was a perceived threat of such during the design stage, it would be compensated for.
However, “failure” can constitute more than just a component malfunctioning or not performing in the field as intended…especially when a functional coating process is required.
For instance, would a part that requires 100% sorting after a coating operation – when that cost was not factored into the process – due to inadequate structural design be deemed a “failure” as well? We think it would (read our white paper regarding this specific topic).
Manufacturing design engineers should be sure to consider some of the following when in development of a component that will require a post coating application process:

I am currently an engineering intern seeking to earn my degree next spring. I started working for the DECC Company in the beginning of 2016 and the only prior experience I had in the coating industry was when I used a can of peelable spray paint on my rims to cover up some rust spots.
In my brief one and half years at DECC, I can sum up what I’ve learned about the coating industry in three simple sentences: Continue reading Custom Coating Through the Eyes of an Intern
Producing quality product within a specified tolerance is a battle that every manufacturer, in every industry, fights every day.
Design engineers have the task of determining how tight of a tolerance should be allowed when developing a part and usually operate in the mind set of “the tighter the better.” In some cases, unnecessarily tight tolerances just drive up the cost of a component unnecessarily, but that is a debate for a different day.
It is understood that a component designed to need a functional coating would have its tolerances accordingly compensated. However, if the component you’re dealing with Continue reading Functional Coatings and Tight Tolerances: No Need to Worry About a Costly Redesign
Corrosion is one of the leading causes of component failure across all industries. In terms of functional coatings that offer corrosion protection, there are essentially two categories: sacrificial coatings and barrier coatings.
The type of corrosion being combated, as well as if there are additional performance criteria that the coating must achieve, will help determine which type of coating system you should use.
First, an explanation of the two categories:

As there is a vast array dry film lubricants on the market, there are just as many different applications in which these coatings could be utilized.
Given the countless combinations of coatings and applications, determining which one would be best for your application can be a daunting task. However, by determining a few key variables, the options can be scaled down considerably.
When trying to decide which type of dry-film lubricant would be best for your application, the following should be considered:

Simply put: there are part geometries that lend themselves to a dip-spin coating process and those that do not.
In fact, even though DECC is a rack-spray facility, we will be the first to direct a customer to a dip-spin competitor when asked to quote a part that is suited for such an application. A rack-spray process can be two to three times more costly than a bulk process and, when it makes sense, we want our customers to take advantage of such pricing.
However, for part geometries that are not suited for dip-spin, quality and delivery issues quickly negate any “savings” when the true cost of processing is evaluated.

One of the fears associated with a rack-spray coating process is that, due to the part being “fixtured” and resting on a hook, the part will not have complete coverage. And without complete coverage, the functionality of the coating is in jeopardy.
It is technically true that there will be a “witness mark” where the part is held on the fixture.
However, in regards to the “functionality” aspect of the coating; it depends on what the customer’s perception of “in jeopardy” is.
For example, below is how a typical witness mark on all rack-sprayed parts would look like. For reference, the hole this was racked thru is 8.5mm in diameter.
