About JKL Mouldings Ltd

JKL Mouldings is a UK-based plastic injection moulding company supporting customers from initial concept through to full production and assembly.

We specialise in managing complete projects, providing a single point of contact for tooling, moulding and secondary operations. This approach reduces complexity, improves communication and ensures projects are delivered efficiently and to a consistent standard.

Our manufacturing capability includes a wide range of injection moulding machines, enabling us to support both small, technical components and larger, higher-volume parts across a variety of industries.

In addition to moulding, we offer a comprehensive range of secondary operations including assembly, inserts, sealing and finishing processes. By integrating these services, we help customers streamline their supply chain and reduce overall project risk.

JKL works closely with a trusted UK-based supply chain, offering greater visibility, shorter lead times and improved responsiveness compared to offshore models. This is particularly valuable for customers looking to re-shore production or improve supply chain reliability.

We are committed to quality and continuous improvement, operating to recognised industry standards including ISO 9001 and ISO 14001, and holding EcoVadis Bronze accreditation.

Whether supporting new product development or transferring existing production, JKL provides a flexible, collaborative approach focused on delivering practical, cost-effective solutions.
