Precision Machined Plastic Parts Since 1972

Our Company

Since 1972, D&F has been a family-owned company manufacturing products for the Connector, Telecommunications, Aerospace, Medical, Electronics, and Valve Industries. The company was founded by my father-in-law, Frank Duh in his garage. We have grown a bit since then and continue to uphold the exceptional service, quality, and delivery for which D&F has come to be known.

Our Mission

At D&F, our mission is to make your job easier. Our 4,000 square-foot facility has eight dedicated employees who offer personalized, value-added service, which is nearly unheard of in today’s ever-changing business climate.
