High-reliability seals and mouldings

DP Seals manufactures custom rubber seals and mouldings to the highest levels of precision and quality. These are custom rubber moldings for many of the world's leading civil and military, fixed and rotary wing aerospace programmes. Global companies such as Eaton Aerospace and Moog rely on DP Seals’ materials knowledge and AS9100B certified rubber moldings engineering experience, whether it’s for the oldest flying Andoveror the latest Dreamliner and Black Hawk.

Developing custom rubber mouldings for demanding applications requires rubber custom molders with knowledge both of materials and environment. From material blend selection through tool development and prototype mouldings to product delivery, DP Seals works closely with some of the world’s leading aerospace engineers on the following programmes:

Business jets seals and mouldings: BAE 125, 146 Whisperjet, Bombardier Learjet 45, Cessna 850 Citation Columbus, Embraer Legacy 450 MLJ and Legacy 500 MSJ

Seals and mouldings Commercial airliners: Airbus [most variants], Boeing 787 Dreamliner, Fokker F100 mid-size and F28 short haul

Aero Engine seals: Rolls Royce Trent XWB Engine

Helicopter seals and mouldings: AgustaWestland AW101 medium lift, Sikorsky Black Hawk UH-60M upgrade and Westland Lynx - and the Bell Boeing V-22 Osprey Tiltrotor

Military aircraft seals and mouldings: BAE Harrier jump-jet and Hawk advanced trainer, Lockheed Martin F-35B Lightning, Panavia Typhoon (Eurofighter) and Saab Gripen

The DP Seals edge

DP Seals regularly takes on awkward production problems where others have failed. Our hard-earned reputation for innovative problem solving, combined with our knowledge and experience in polymer formulation, have proven invaluable, especially where performance and longevity in demanding environments is of paramount importance.

Rubber mouldings materials and technology

Material selection is key to long-term performance: aerospace seals and aerospace rubber mouldings must operate under wide temperature and pressure ranges, with fuel oils and lubricants. From nitrile, neoprene and silicone through high-performance Viton and FFKM to cutting edge polymers like silicone perfluoroelastomer and nanotech rubber, DP Seals uses its rubber chemistry experience to work with compounders and develop the right polymer blend for your application.

Engineering of moulding prototype tooling and tool development

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 moulding prototype tooling in optimum time without compromising precision or quality. However, effective tool development requires more; 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 rubber moulding tools, including in-tool rubber to metal bonding.

Production by polymer transfer moulding

Tool and material meet on the shop floor. DP Seals' polymer transfer moulding systems - characterised by low set-up times and high accuracy, precision and repeatability - are ideal for short prototype runs as well as volume production across a wide range of polymers. The biggest presses take significantly larger tooling allowing manufacture of larger, more complex mouldings  – such as anti-vibration mounts for jet fighter fuel pylons - as well as increased batch sizes for high volume components integrated with Kanban and JIT-enabled processes. High performance non-contact video measuring equipment is used to monitor on-going precision, with full SPC analysis.

Product cleaning

DP Seals pioneered cryogenic de-flashing and now has two of the most advanced fully automated CNC-controlled cryogenic de-flashing machines of their kind in the world. Cryogenic de-flashing makes the essential cleaning process faster, more efficient and more effective. These are two of six product-specific cleaning systems installed to ensure all output is free from flashing and defects.

Quality control AS9100B custom rubber mouldings

From initial design through manufacture to final despatch, our rigorous quality process monitors every stage – regardless of production volume. DP Seals' TQM approach to quality control is second to none. The company is one of a very select band of custom rubber moulding companies in the world to achieve AS 9100B. It was also one of the first custom rubber moulding companies in the UK to achieve ISO 9001. Although not strictly quality, we also have ISO 14001 Environmental Management and OHSA 18001 Occupational Health and Safety accreditations.

At DP Seals, our passion to understand the cost and performance benefits presented by new polymers is underpinned by a continuous investment in engineering and production processes. Involvement at the earliest stage lets us add real value to your rubber component development, advising on materials, tooling and performance to help ensure your products meet your expectations. Whether it's simple aerospace o-rings for a lubrication system, anti-vibration mounts, or cable boots for an avionics cable loom, make DP Seals part of your development team and gain that all-important unseen advantage.
