Our customer testimonials for Liquid Coating Capabilities
The best testimony to the performance of our liquid coating systems come from customers with the highest production standards.
We experiences significant paint savings, stretching its use of paint from 21 drums per gallon to about 32 drums per gallon with the A7A gun systems. Paint changes can also be done on-the-fly, saving production time and material. Since we installed the Nordson system, we haven’t had a single drum of waste.
“We’ve been associated with Nordson for years and they’ve always provided superior technical knowledge and support. We considered other alternatives, but knew Nordson would back their
technology with service and support we could count on.”
When you’re mixing by hand, if the material isn’t mixed to the correct ratio and used within the correct time frame, it won’t apply correctly. This means a significant amount of wasted materials that becomes very costly. The Nordson Optimix is easy to program and operate. It’s simply an effective, well thought-out product. You pull the trigger, and bam – there you go.
