Edhar - South Africa has the capacity to manufacture a wide array of customized solution-based wear products, specifically engineered and well suited for processes in mining, mineral processing, petrochemical, power generation and many other manufacturing and processing industries.

Our Polyurethane production facility is based on the hot casting process. While comparing injection mould to cast processes, there are many factors to consider. Though injection moulding can be cost effective when producing larger quantities, injection-moulded polymers do not offer the superior physical properties of open-cast thermoset polyurethane. This is because the hot cast process provides a long slow cure and post cure that enhances the cross-linking of the polyurethane molecule, something that cannot be accomplished in the relatively short processing time associated with injection moulding.

Although producing open-cast thermoset polyurethane components may be more labour intensive, the result is a much greater range of physical properties which translates into better overall performance in the long run, as well as significant cost savings.

Our facility has the capacity to continuously cast up to 2 tons of Polyurethane per day. Edhar - South Africa additionally manufacture and supply all fabricated and machined component inner sleeves, impeller thread and structural frames for parts, meeting client specifications throughout the production process.
