How to Avoid Setting a New Part Up for Failure

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:

Functional Coatings and Tight Tolerances: No Need to Worry About a Costly Redesign

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 Protection: Sacrificial vs Barrier Coatings

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:

Zinc-Flake Coating

Over 80% of the requests we receive from current or potential customers deal with the application of coatings to combat corrosion, be it environmental, chemical or temperature related. However, of these requests, the majority are environmental and can be solved with a zinc-flake coating solution. We will delve into ways to combat the other types of corrosion in another post.
