About Dual Manufacturing Co., Inc Testing Sieves

Dual Mfg Building    Dual Mfg Building


Since its founding in 1942 by Leonard J Newon, Sr., Dual Manufacturing Co., Inc. has produced testing sieves and related products and has become the industry leader and has always been known to product the highest quality products without sacrifice. Today, the Newon family still faithfully uses his manufacturing methods of production while incorporating state-of-the-art machines to accentuate the skills of the tradesmen. In fact, Dual Mfg is the only sieve manufacturer that is still owned/operated by the founding family, all others have either merged or been bought out by financial institutions. In addition, Dual Mfg does not subcontract any part of the manufacturing process. We keep all aspects of manufacturing inside the organization. This is one of the reasons why our quality has never been tarnished.

The concepts of quality and technical development cannot be seen separately. In order to meet specific customer demands and to optimize the production process, special purpose machines, incorporating advanced controls, have been developed and built-in-house at our factory. Dual Manufacturing Co uses only the highest quality alloys in their manufacturing process all of which are certified by the manufacturer as complying with stringent metallurgical standards.

Our commitment to quality and service has been the cornerstone of our company since it began in 1942.

Within the organization, Dual Mfg has encouraged generation training. We currently, within our employee base, have families that have multiple generations working their way up.
