Precision design for exceptional results
We design injection mould tools entirely in-house, working with you to turn your part into a precision-engineered tool built around your production needs. It starts with a detailed brief and a clear process, so your project stays on track from the first conversation to delivery.
Our team takes ownership of every stage of design and toolmaking, keeping targets and deadlines in view throughout. We see ourselves as your partner in getting a part into production, not just a supplier of steel.

Tooling types we design
Our design work covers the full range of injection mould tools, from straightforward single-impression tools to complex multi-cavity systems. Each one is engineered around your production requirements, material and volume targets.
- Single and multi-cavity tools
- Hot runner systems
- Cold runner systems
- Auto-unscrewing tools
- Hydraulic moving cores
- Mechanical moving cores
- Split cavity tools
- 3D cavity design
- Sprung core tools
- Mechanism tools
Our in-house design process
Every tool is designed at our Burnley facility, giving us full control over quality. We keep you informed at every stage, and nothing is cut until you have approved the design.
- Brief and consultationVolumes, materials, performance, budget and deadlines all agreed up front, with design for manufacture advice on your part.
- 3D design in Autodesk Inventor ToolingA bespoke tool designed for function, cycle time and ease of manufacture.
- Review and approvalThe design is shared with you, and any changes are made together before manufacture begins.
- Manufacture and validationBuilt in-house, trialled to your specification and delivered ready for production.

Why design matters
The start of a project matters as much as the engineering that follows. Getting the design right from the outset sets how long your tool lasts, how well it runs and how efficient your production is.
A tool designed properly for its job needs replacing less often and causes less downtime. That is why we put precision and durability first, so your tool performs consistently, run after run.
Precision
Tight tolerances designed in from the start, for accuracy and consistency in every run.
Durability
Good design reduces wear, extends tool life and lowers your long-term costs.
Efficiency
Designs optimised for cycle time and less material waste.
Built for you
Every tool tailored to your production goals, material and budget.
Pioneers of Autodesk Inventor Tooling
Kavia was the first company in the UK to trial and implement Autodesk Inventor Tooling. That early investment means more accurate, more efficient tool designs, which translate into better performance and longer tool life.
