The art of pattern making.  The precision of computer tooling.  And the skills of qualified mould makers.  Put them all together and you have Proto Mould, a division of Ramsden Industries and a leader in disamatic foundry pattern equipment and permanent mould tooling since 1966.

As certified mould and pattern makers, our experienced craftsmen have also become integral players in the plastics industry, supplying a full range of moulds and patterns for numerous applications. We have produced visual mock-ups, prototypes and master production tooling for a wide range of industries including automotive, industrial, hardware, plumbing, agricultural and luggage.

Located in the hub of southwestern Ontario halfway between Toronto, Canada and Detroit, Michigan, Proto Mould has satisfied both small and large customers across North America for 30 years by turning their tooling challenges into viable solutions through a analytical and hands-on approach to problem-solving.

Proto Mould's professionalism is evident from the very start.  Customers appreciate the open dialogue that is created from the initial introduction to our operation.  In addition, our customer service personnel's many years of direct experience on the production floor ensures a focused and effective partnership with you.  From design and engineering to quality control, each functional area is consulted before any tool build process is ever started.  Our long term working relationships with customers and credibility can be attributed to our responsiveness, genuine concern, and appreciated input.  This allows us to work and grow together.
