About Us

Advantage Blow Mouldings, formerly known as Hadley Hargreaves, specialises in the production of high-quality extrusion blow moulded components from our facility in Presteigne, Powys.  We are willing to develop and manufacture parts in relatively low volumes volume (50 to 150,000).

We can assist with product development and tooling, as well as fulfil any assembly and testing requirements.  Our experience and technical capabilities make us the ‘first choice’ for many manufacturers of bespoke equipment and vehicles in the automotive sector.

We have a strong association with a consortium of Welsh universities. This relationship enables us to develop recycled and bio-based polymers specifically tailored to a customer’s project.

We also work with our long-term strategic partners to supply injection mouldings, rubber/silicon mouldings and rotational mouldings, allowing us to provide a complete and fully managed technical solution. Our services range from initial concept and design to tooling, sub-assemblies, product testing, bespoke packaging, and global delivery.
