Tips for Selecting an Equipment Supplier

Before the internet age, to create a design concept for your equipment you had to rely on either your inhouse engineering knowledge or your vendor’s. Since the internet, we are drowning in opinions as well as information. Maybe it’s time to get back to the basics.

Focusing on the "Yes," Achieving Success

A focus on customers and its employees’ abilities to respond to new opportunities has allowed this Indiana-based custom powder coater to thrive. The addition of a fourth powder coating line will allow them to continue to offer industry leading quality and delivery levels.

Reinventing the Wheel

Corrosion is a fleet-eating problem on commercial trucks that costs the industry $4 billion annually. When the American Trucking Association called for improved corrosion protection in 2005, Accuride accepted the challenge and responded with the trucking industry's first powder coated steel wheel to come with a corrosion warranty.

A Partnership That Paid Off

Faced with the inability to meet corrosion and salt spray testing requirements, they needed some answers quickly. Their customer, a large OEM, required 96 hours of ASTM B-117 salt spray protection on bare steel tubing. One of Hubbard-Hall’s corrosion experts, Larry Ensley, Technical Director, came on site to evaluate the situation. After analyzing their process and running some tests, Larry came up with a solution. By applying Metal Guard 510, a water displacing rust preventative, over Hubfos 150, an iron phosphate, over the bare steel tubing they were able to meet the required 96 hours of ASTM B-117 salt spray protection.

Factors To Consider For Accurate Coating Thickness Measurement

The heart of any electromagnetic measurement system is the probe. The probe is a very complex system, which performs the conversion of the appropriate measurement method to a reading on the corresponding gauge. Proper selection of the coating thickness instrument and probe will determine the accuracy and reliability of the measurement results. Addressing each factor is critical to providing accurate results for complex challenges faced by coatings professionals each day.

Curvature Compensation:
One of the most common influences on coating thickness is curvature. A curved part can cause erroneous readings without proper adjustment of the gauge and probe. The influence of the curvature varies with the make and type of the instrument but becomes more pronounced as the radius of the curvature decreases. A probe that incorporates the curvature compensation method is ideal.
