Established in 1951

Robert PD Frost & Co Ltd is a family business established in 1951 and has steadily grown ever since. Initially Robert Frost manufactured models and instruments but his engineering skills increasingly led to work with injection moulds and plastic mouldings. The company grew around his love of problem solving and rising to challenges. Over 67 years later, we have earned a reputation for quality, reliability and value for money.
