Materials technology

Seals and mouldings for aerospace applications must deal with high and low pressures, low temperatures, fuel oils and lubricants. Material selection is key to long-term performance. From nitriles, neoprenes and silicones through high-performance Viton Extreme and FFKM to cutting edge polymers like silicone perfluoroelastomer and nanotech rubbers, DP Seals uses its 30-year experience in rubber chemistry to work with compounders to develop the right blend for the application.

DP Seals' extensive CAD/CAM integration builds a direct, high-efficiency link from engineer's desktop to in-house tool room, eliminating errors and ensuring prototype tooling in optimum time without compromising precision or quality. The company's use of 3D printing of prototype seals and mouldings further aids in keeping clients' development processes on time - and budget.

Tool production requires more than equipment: it requires knowing how materials behave in manufacture and how to section a tool to ensure a reliable end product. DP Seals has over 30 years experience in designing custom rubber moulding tools, including in-tool rubber to metal bonding.

Find out more about how DP Seals brings materials, engineering, tooling, production and quality together in perfect harmony to deliver precision solutions.
