Hardness tester checks automotive valves

An advanced micro-Vickers tester has a fully integrated digital measuring system with automatic load control, a robust XY-stage with a minimum reading of 0.01mm and hardness computation.

Founded in 1946, G and S Valves specialise in manufacturing a wide range of high quality automotive valves from 'one-off' prototypes destined for engine development, to scheduled contracts for larger companies.

After a recent substantial investment was made in establishing a sophisticated in-house, pulsed plasma treatment facility, a decision was made to invest in a new state-of-the-art bench hardness tester for use within the company's busy metallurgy laboratory.

The requirement was extremely exacting and specific and after examining the available alternatives, an advanced 401-MVD micro-Vickers tester was purchased from Bowers Metrology.

Amongst many other superior features, the ingenious new tester boasts a fully integrated digital measuring system with automatic load control, a robust XY-stage with a minimum reading of 0.01mm and on-board hardness computation and statistical functions.

An integrated printer and RS 232 output caters for the reports frequently required by the demanding automotive industry.

Andrew Grenside, G and S Production Director explained.

"Our new Bowers hardness tester has proven to be a great purchase for us, it is accurate, easy to use and most importantly, helps us to uphold our excellent reputation for the first class quality of our automotive valves.
