D&K Engineering Inc. reported revenue in the $80 million to $100 million range during the fiscal year that ended Sept. 30. That is up from $63.7 million in 2012 and $37.0 million in 2011.

Privately held D&K, based in Rancho Bernardo, said that a local subset of its business — San Diego manufacturing — grew more than 90 percent over the past 12 months. The business offers a spectrum of services from initial design to final manufacturing. Some of the San Diego manufacturing resulted from research and development work transitioning to the next stage in the product-development cycle.

D&K also does some of its work in Singapore.

The company makes a variety of products, including medical devices and self-service kiosks. It makes the kiosks for San Diego-based EcoATM that buy back cell phones. Publicly traded Outerwall Inc., whose businesses include Coinstar and Redbox, acquired EcoATM for $350 million in July.
