Plastic injection moulding for UK defence and security applications

Summary

OGM manufactures plastic injection moulded components and assemblies for defence and security applications from two UK manufacturing sites in Oxfordshire and South Wales. With almost 60 years' manufacturing experience, ISO 9001 and ISO 14001 accreditation, and Cyber Essentials certification, OGM supports low-volume, high-precision production for regulated and security-conscious supply chains.

Overview

Defence and security programmes need suppliers who can be trusted with precision, confidentiality and continuity of supply. OGM has manufactured plastic injection moulded components in the UK for almost 60 years, from two sites in Oxfordshire and South Wales, and is Cyber Essentials certified a baseline the UK government requires of suppliers handling sensitive information.

60+ Years UK manufacturing
2 UK sites — sovereign supply

We work in low-to-medium volume production, which suits the specification-driven, security-cleared nature of defence procurement better than high-volume commodity moulding. Our in-house toolroom means tool changes, repairs and modifications for classified or ITAR-restricted programmes can be managed without third-party handling.

Frequently asked questions

Q.01 What plastics are used in defence and military components?

Defence and security applications typically specify high-performance engineering plastics chosen for durability, dimensional stability and, in some cases, flame or chemical resistance. OGM works with a range of engineering polymers suited to demanding specifications material choice is confirmed against the customer's own specification and testing requirements.

Q.02 Why is plastic injection moulding used in defence manufacturing?

Injection moulding produces precise, repeatable components at the tolerances defence specifications demand, while allowing rapid tooling changes when programme requirements evolve an advantage over machining for medium-volume, specification-led production runs.

Q.03 What accreditations does a defence injection moulder need?

Buyers in defence supply chains typically look for ISO 9001 quality management as a baseline, alongside sector-specific credentials such as AS9100D (aerospace/defence quality management) or JOSCAR registration (the defence and security industry's supply chain qualification system). OGM holds ISO 9001:2015 and ISO 14001:2015.

Q.04 What is a secure or sovereign UK supply chain for manufacturing?

A sovereign supply chain means components are designed, tooled and manufactured within the UK, reducing dependency on overseas production for sensitive or restricted programmes. OGM manufactures from two UK sites in Oxfordshire and South Wales.

Q.05 What does ITAR mean for a UK plastics manufacturer?

ITAR (International Traffic in Arms Regulations) is US legislation controlling the export of defence-related articles and technical data, including to non-US manufacturers working on US-origin defence programmes. UK suppliers working on ITAR-controlled programmes must follow specific handling and access-control procedures.
