Our history

[rev_slider alias=”Our-history”][/rev_slider]

A merger of two manufacturers

As Whistle Stop Plastics Ltd and Modern Moulds Ltd, we were manufacturers with a shared goal, to listen to our customer’s ideas and help them achieve it. We have been working together for many years, and with our mutual goals and values, our partnership is a strong asset.

As a result, in June 2017, WSM Plastics was created.

We can help you achieve your goals by offering a complete service, all under one roof.

Our story

1987 – Modern Moulds and Tools Ltd was born. The company offers businesses in the plastics industry high-end design and bespoke manufacturing of moulds.

1997 – Whistle Stop Plastics was established by Modern Moulds and Tools as their sister company.

Modern Moulds and Tools set up Whistle Stop Plastics following customer feedback for an injection moulder to work alongside them.

Although two independent companies, both worked together to provide injection moulding and tooling services to customers.

2011 – Whistle Stop Plastics Ltd and Modern Moulds Ltd were integrated into the Bright-Tech Investments Group.

Bright-Tech Investment Group is the parent company of WSM Plastics.  All Bright-Tech Investments Group businesses share the same values of customer focus, premium quality, and innovation.

2017 – Whistle Stop Plastics Ltd and Modern Moulds merge and become WSM Plastics Ltd
