Design for Manufacture

Schedule a call

Liondell’s Design for Manufacture (DFM) services help businesses refine plastic component designs so they can be produced efficiently, reliably and without unnecessary cost. By addressing manufacturability early, we reduce risk, avoid redesigns and ensure every part is optimised before tooling begins. The result is smarter design that leads to smoother, more predictable production.

Our Design for Manufacture process combines detailed CAD analysis, practical engineering insight and decades of tooling experience. We offer a focused set of services to strengthen your design from the outset:

  • Design Reviews
  • CAD Analysis
  • Mould Flow Simulation
  • Cost Optimisation
  • Tooling Recommendations

These evaluation steps uncover issues such as weak points, undercuts, wall-thickness concerns and potential defect areas. Mould flow simulation predicts how material fills the tool, helping prevent warping, voids and sink marks. Every recommendation is rooted in real production requirements and delivered by a UK-based, family-run engineering team with over 50 years of combined experience.

Our structured workflow keeps your project moving efficiently and ensures every stage is clear and controlled:

Initial Review

Understanding your design goals and current CAD models.

Analysis & Simulation

Using CAD checks and mould flow to predict performance.

Refinement & Recommendations

Improving manufacturability, tooling and cost.

Prototype (Optional)

Early testing before full-scale tooling.

Design Approval

A production-ready design validated for manufacture.

We support sectors including automotive, medical, industrial, consumer goods, electronics and packaging. With Liondell, your design becomes practical, efficient and ready for tooling—giving you confidence before production begins.

We have worked with Liondell on a number of very technical projects. With their strong mould design knowledge and experience we have been able to achieve some fantastic results. Their standard approach to the full process ensures all elements are considered, discussed and approved at each stage to ensure the final tools meet or exceed the expectations of all involved. We look forward to continuing to work together.”

It is a pleasure to work with Liondell (Andy & James). Their process is very simple but detailed, from the initial quote, through DFM, GA activities to tool receipt. Their process for pre-shipment check and UK toolroom inspection BEFORE we receive the tools works extremely well. We have not had a fault with the tooling we have received from them. We look forward to working with them in the future”
