Manufacturing facilities in today’s competitive market strive to produce the highest quality product. In this case study we will discuss the importance of recognizing every company’s desire to produce a premier product with the highest first place transfer efficiency.
A Custom Fabricator, producing products for the truck & and Bus industry
In order to distinguish them within the marketplace, the current manufacturing process needed to meet customer’s mil specs. Their current Powder Units were not producing enough Mils per MFG spec with a Quality finish. Examination by quality control engineers revealed that they were getting back ionization and orange peel when applying more powder and second coats. They determined that each operator had different settings and too much powder output. In addition they did not understand current and voltage and how they relate to a quality finish and high transfer efficiency.
In partnership with the customer, Air Power implemented an Gema OptiFlex 2 manual powder unit. The unit comes with 3 presets: 1: Flat Parts, 2: Recess/complex parts and 3: Recoat mode. In addition these cannot be changed by the operator and allowed ease of use with a simple repeatable process. The Patented Digital Valve control allowed for consistent precise powder output, powder savings, and reproducible coating results.
Currently, the customer is meeting their mil spec and producing repeatable results and has increased there transfer efficiently that has provided a 1 year Return on equipment investment.
Dedicating your powder hose specific to your color and special type of powder can save you time in color changes and prevent costly rejects. It can speed up your paint process, eliminate powder contamination and reduce clean up time. If you are frequently changing your powder color throughout the day, this is a great way to quickly and easily eliminate pain points and improve your application process.

Air Power Manufacturing Solutions was invited to attend Gema’s 2019 Symposium held in a small town nestled in the mountains of Pontresina in Graubünden, Switzerland. Two of Air Power’s application specialists, Travis Stirewalt and Bob Cosey, traveled to Switzerland to represent Air Power at the Symposium. Gema invited distributors from 64 countries around the world to participate in this 4-day experience in the Swiss Alps.
The event kicked off with a visit to the worldwide headquarters of Gema in St. Gallen, Switzerland. The group spent the day having the Gema “Lab Experience” which involved touring the lab facilities and interacting with the many systems they have on display. Gema has everything from small, handheld manual applications to large complex fully automated and robotic systems available in their lab. All the systems are fully operational and show the versatility of the line of equipment that Gema has to offer.
Over the three days, the group spent time in an Educational Forum focused on new Gema products to be released to distributors to launch in April/May 2019. Gema presented groundbreaking projects on automation, gave insights into new sales strategies, and demonstrated important standards on service excellence.
THURSDAY: SNOW GAMES
Gema transported the entire group to a ski lodge located nearby, where they had some special events planned for the day. They spent the morning participating in tubing, snow shoe races and other team building games in the snow while enjoying the beautiful view of the Swiss Alps. Gema used this opportunity to unveil the first manufactured OptiFlex Pro units featuring their new design. The group spent Friday learning all about the features of Gema’s new design and the changes they’ve made to enhance the users experience and improve the OptiFlex system.
We would like to thank Gema for inviting our team out to participate in the 2019 Gema Symposium!
