About Us

Family of Companies

Back in 1950, Sinclair & Rush, Inc. began supplying a small line of dip moulded products to a handful of customers.  Today, we boast of manufacturing and distribution capabilities on a much larger scale; a global scale.  With manufacturing and selling operations spanning the globe:  North America, Europe, Asia, Latin America and Australia, Sinclair & Rush supplies over 20,000 customers.

By offering products that provide a solution, we’ve earned the status as a premier supplier to some of the world’s leading manufacturers.  To that end, Sinclair & Rush is constantly looking for ways to develop new technologies, applications and materials that create value for our customers.

Currently, six companies operate under the Sinclair & Rush name:  StockCap, VisiPak, GripWorks, VynaFlex, Castle Bay and Soffware.  All divisions are supported at every global location.  Each division specialises in its own product category, offering new and unique solutions to product protection problems.

Our ability to provide a full line of complementary processes and products uniquely positions us as one of the world’s leading multi-processors of plastic components.
