A design only works if it can survive being made, assembled and used.
npd’s mechanical engineering takes a product from design intent to something that can actually be built, covering structural design, tolerancing, materials selection and design for manufacture.

Structural & Mechanical Design
Working through how a product holds together, moves and withstands the forces it will actually meet in use.
Tolerancing & Design for Manufacture
Developing the visual language a product or product range is recognised by, from name and mark through to how it looks across every touchpoint.
Materials & Process Selection
Choosing materials and manufacturing processes together, so mechanical performance and cost both hold up at the volumes required.
Areas of Expertise
Mechanical Design
Designing how a product’s components fit, move and hold together under real-world use
Tolerancing & GD&T
Setting tolerances that are tight enough to matter and realistic enough to manufacture
Design for Manufacture
Checking every mechanical decision against how a product will actually be produced
Structural Analysis
Assessing how a design performs under load, stress and the conditions it will face in use
Materials Selection
Choosing materials for mechanical performance, cost and manufacturability together
Assembly & Fixturing
Designing how a product goes together so assembly is fast, repeatable and low-error
Frequently Asked Questions
Structural and mechanical design, tolerancing, materials selection and design for manufacture, taking a product from design intent through to something that can be built.
Yes. npd has delivered precision-engineered components to defence specification, including work for BAE Systems on the Typhoon simulator programme.
Yes. npd’s mechanical engineering covers everything from internal mechanisms through to enclosures designed to protect electronics in demanding environments.
Industrial design shapes how a product looks and feels. Mechanical engineering makes sure it works reliably and can be manufactured. npd runs both in parallel rather than in sequence.
Yes. Mechanical engineering decisions are made with manufacture in mind from the start, feeding directly into manufacturing support.
