With over 45 years of experience, UML is the preferred inflator choice for the best lifejacket manufacturers worldwide.

United Moulders Limited (UML) a brand of  Ocean Signal Ltd. started manufacturing plastic injection mouldings in Hampshire, England over 45 years ago. The company originally specialised in the conversion of high performance engineering polymers into advanced technology products for the aerospace and defence sectors. Added value assembly and testing processes became firmly established in the company’s culture.

The original MK3 Automatic Lifejacket Inflator was developed for the Ministry of Defence to provide lifesaving assistance for naval military personnel. After the product was launched in 1964, the MK3 inflator was adopted by the leading commercial and leisure inflatable lifejacket manufacturer, Crewsaver of Gosport, Hampshire.

In 1998, the MK5 Automatic Inflation unit was launched along with a Manual Inflator, Oral Inflator, and Manifold Adaptor. The product range, originally approved in accordance with the requirements of the CEN lifejacket Standards, was quickly adopted by most European lifejacket manufacturers.

All the manufacturing and assembly processes are closely controlled by the company’s Quality Management System which is certified in accordance with the accreditation requirements of ISO 9001.

Today, our professional design team focuses on upgrading the functionality and performance of existing products while developing new devices to ensure the UML range of lifesaving products benefits from continuous, world-class improvements. This continuous product development program is fully supported by all new products being approved to ISO:12402 Part 7.

UML was acquired by The ACR Group in August 2017, and the brand is currently managed by Ocean Signal Limited.

UML operates a quality management system which complies with BS EN ISO 9001:2015, which is accredited by The British Standards Institution.

Rigid Quality Assurance procedures are followed from the initial product development concept to final delivery to our customers. This includes pre-production testing and subsequent approval at Fleetwood Testing Laboratory to the relevant CEN and/or SOLAS requirements. In production, clear and concise work instructions are displayed for the assembly technicians, with various sign-off stages, to ensure the components are to standard and incorporate specific customer test requirements. The main body of the Inflation System is 100% function tested using automated testing equipment to ensure you can depend on our products, and a percentage of finished products are test-fired to ensure the optimum performance is maintained.

A substantial commitment to practical testing of UML products, provides the stimulus for product upgrades and improvements. Combine these ongoing product developments with meeting the demands of the latest ISO Standard (12402 part 7) for Personal Flotation Devices and Inflatable Lifejacket Components and the result is that UML products remain at the leading edge of industry performance.

UML product improvements or new product ideas are documented and developed by our professional team of Design Engineers and Project Managers who take the individual projects through concept, prototype and then onto the tooling and production stages.
