Automotive expansion tanks are an item which we are frequently asked to produce for our many automotive customers.

Our hot plate welding capabilities, our experience in the automotive sector, and our injection moulding capacity make us a popular choice for our automotive customers who need expansion tanks to be manufactured for their vehicles.

Over the last 3 years RP have worked closely with various automotive customers to develop a range of coolant expansion tanks, not only for conventional petrol and diesel engines but also for the development of battery cooling in a range of new breed electric vehicles.

RP manufactures the aluminium tooling and injection moulded parts for these tanks on-site in Kingswinford. We also have our own hot plate welding machine here.

We supply assembled prototype components for testing and development vehicles.

As part of this process of manufacturing automotive expansion tanks, RP has commissioned a custom-built hot plate welding machine, which is located in our production facility here in the West Midlands.
