Choosing the Right Powder Coating Company: A Comprehensive Guide for Manufacturers

Choosing the right powder coating company can absolutely make or break the end quality of your products. After all, the surface finish is the first thing that potential customers or end users see. Regardless of the quality of the metalworking underneath, a subpar powder coat will leave your overall products feeling inferior.

With that in mind, how exactly do you determine who is the best powder coater for your project? Below, we lay out some of the most crucial questions you should ask before signing the contract.

Questions to Ask Before Choosing an Industrial Powder Coating Provider:

At Winona Powder Coating, our motto is quality from start to finish. That’s much more than a mere tagline for our company. With more than 50 years of experience under our belts, we’ve established a system of absolute quality assurance that extends from the onboarding process all the way through to product delivery. We are an ISO 9001-2015 certified coater committed to superior quality and consistency for every product.

What quality certifications do they hold?

The first step is to make sure your potential powder coating company offers the level of quality and repeatability that your products require. It’s not enough to merely look at a few sample parts. Instead, choose a highly experienced powder coater with a long history of delivering high quality results – preferably a provider backed by certifications that guarantee a certain level of consistency.

At Winona, since 1974 our motto has been quality from start to finish. An ISO 9001:2015 certified powder coater with more than 50 years of experience behind us, our company embraces a culture of uncompromising quality and consistency. Our robust quality control processes extend from the onboarding process all the way through to product delivery.

Can they accommodate the part sizes you need?

Obviously it’s also crucial to make sure your potential powder coater can handle the part sizes that you need. You should not only consider your current part size requirements, but also any potential needs for large part powder coating. That way you can stick with the same powder coating company down the line.
