Capabilities
Tool making
We design, manufacture, modify and maintain injection mould tooling in-house at our UK HQ. Our customers have come to expect faster lead times and can have full confidence in quality, even for complex programmes.
From early concept to production-ready tooling, our expert engineers work closely with customers to develop the most effective solution for each part.
We manufacture, adapt and maintain tooling in our onsite toolroom, while also drawing on trusted global partners when needed.
This hybrid approach gives us full control over precision and lead times. Our knowledge of materials, moulding techniques and downstream processes means we can optimise tooling for product performance, from weight reduction to material flow and surface quality.
Our advanced CAD and modelling tools allow us to simulate how materials will move within the mould, generating better surface finish and engineered performance from the start. We combine this with lab testing and validation, working with trusted partners to ensure tools meet precise customer requirements.
Because our tooling team is on site, we can adapt quickly, reduce risk and guarantee that every tool performs to international standards.
From initial design to maintenance, our in-house team builds tools that perform.
