About the Liondell family
About us
Liondell is a family-owned engineering business based on the South Coast, specialising in plastic product design, tooling and manufacturing support. With over 50 years’ combined experience, we help clients turn ideas into reliable, production-ready components and tooling.
A Family Business with a Clear Mission
At Liondell, our mission is simple: deliver precision, quality and long-term performance in every project. We approach each design and tool with the care, attention and accountability that define a family-owned business. Guided by strong values, we focus on producing solutions that not only look right but perform reliably in real-world manufacturing environments, supporting clients from concept through to production.
Expertise at Every Stage
Plastic Product & Part Design
We design plastic components that balance functionality, manufacturability and visual appeal. Starting from a client brief or early sketch, we create detailed CAD models that account for material selection, wall thickness, tooling considerations and production constraints. This ensures every part is engineered to perform reliably from prototype through to full manufacture.
Re-Design of Existing Products
We support clients in improving existing plastic components by enhancing durability, correcting weaknesses and refining performance through smarter engineering. Using detailed analysis and CAD redevelopment, we optimise geometry, reduce material waste and resolve issues that may cause tooling or production challenges. The result is a more efficient, reliable and cost-effective component ready for manufacture.
In-House Concept Development
Drawing on decades of experience, we develop in-house concepts that solve common challenges in plastics manufacturing. These innovations help clients accelerate development, explore new opportunities and benchmark ideas against proven engineering principles, reducing iteration time and improving product readiness.
Integrated Design-to-Tooling
Our design work is carried out with tooling, processing and production in mind from the start. This integration eliminates unnecessary revisions and creates a seamless transition into tooling manufacture. By aligning engineering and production requirements early, we minimise delays and ensure the finished tool accurately reflects the approved design.
Turning Designs into Reliable Products
Every design undergoes refinement, testing and dimensional checks to confirm it performs as required. Our iterative process reduces risk and ensures the product is validated before tooling investment. Clients receive the confidence needed to progress, knowing the final design has been reviewed for accuracy, functionality and long-term performance.
Global Expertise in Tool Manufacture
Toolmaking & Global Partners
Liondell works with vetted toolmaking partners across the UK, Europe and the Far East, ensuring high-quality tools regardless of location. Our UK team manages every project, providing consistent communication, competitive lead times, cost options and reliable tooling performance supported by global capability and long-standing manufacturing relationships.
Supporting Clients Through Production
Injection Moulding & Supply Chain
We support clients throughout production by supplying prototype or manufactured parts during development, keeping progress transparent and collaborative. For UK customers, we offer ongoing production supply. When tooling remains overseas, our streamlined logistics ensure efficient delivery, enabling a smooth bridge between design, tooling and full production.
