How to Choose the Right Dry Film Lubricant for Your Application

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:

Infographic: The True Cost of Dip-Spin vs Rack-Spray

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.

Rack-Spray and the Dreaded “Bare Spot”: Don’t Let This Be a Deal Breaker

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.

Need Coating in Some Areas and Not Others? Here are Five of the Most Common Masking Types

When needing a functional coating application, most components require complete coating coverage on the entirety of the part. When there are instances where this is not the case – such as cosmetic, fit or function implications – masking of certain areas of the part is necessary.

If an area of a part must be masked, there are a variety of options depending on component geometry, mask location and cure temp of the coating being applied.

Below are the five most typical types of masks used by coating applicators, particularly  Continue reading Need Coating in Some Areas and Not Others? Here are Five of the Most Common Masking Types
