Seals and mouldings for sub-sea communications
and oil and gas exploration and production

Efficient, effective operation is the new frontier,
and experience the essential foundation

Elegant solutions  

DP Seals, a leading manufacturer with over 30 years' experience of precision custom rubber seals and mouldings, is uniquely placed to help leverage extra performance from your sub-sea communication, oil and gas exploration components.

Elegant solutions - materials, engineering, tooling, production and quality - working in perfect harmony reveal the beauty of a joined-up solution: from engineer’s desk to quality product, quickly, efficiently and accurately. Continuous investment in engineering and production processes underpins the understanding of the cost/performance benefits presented by new polymers - benefits that give clients an all-important unseen edge.

CAD/CAM integration

high efficiency CAD/CAM route from engineer's desl to high-reliability end productA direct, high-efficiency link from engineer's desktop to in-house tool room ensures prototype tooling in optimum time without compromising precision or quality and eliminating error.

3D Prototyping

The availability of rubber-like materials for 3D printing has allowed DP Seal to add this valiuable new process to its prototyping capabilities, helping clients to further shorten development times.

Whether for prototyping or mass production, tool production requires more than equipment; it requires knowing how to section a tool and how materials behave under pressure to ensure a highly reliable end product.

In-house tooling

Milling machine in DP Seals toolroomThe busy in-house tool room benefits from the latest technology: state-of-the-art vertical machining centres (VMC) and advanced CNC lathes augment existing all-CNC VMCs, lathes and mills and advanced spark erosion and wire cutting capabilities.



Tool and material meet on the shop floor. Characterised by low set-up times with high accuracy and repeatability, DP Seals' transfer moulding capabilities are ideal for short prototype runs and for volume production across a wide range of polymers.

DP Seals pioneered cryogenic de-flashing and now has two of the most advanced of their kind in the world. Cryogenic de-flashing has made the essential cleaning process faster, more efficient and more effective than ever. This is one of several product-specific cleaning systems installed at DP Seals to ensure all output is free from flashing and defects.

Quality control

DP Seals' TQM approach to quality control - built on its demanding AS 9100 accreditation - is second to none and strictly enforced and monitored by the dedicated inspection unit; the company was also one of the first custom rubber moulding companies in the UK to achieve ISO 9001 accreditation.
