Established in 1951

Plastic injection trade moulders, specialising in development and production moulding and toolmaking.

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 70 years later, we have earned a reputation for quality, reliability and value for money. Robert sadly passed away in 2021 but the Company continues to work to his exacting standard.
