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.

npd design team meeting

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

What does mechanical engineering cover at npd?

Structural and mechanical design, tolerancing, materials selection and design for manufacture, taking a product from design intent through to something that can be built.

Can you engineer to defence-grade tolerances?

Yes. npd has delivered precision-engineered components to defence specification, including work for BAE Systems on the Typhoon simulator programme.

Do you work on enclosures and housings as well as internal mechanisms?

Yes. npd’s mechanical engineering covers everything from internal mechanisms through to enclosures designed to protect electronics in demanding environments.

How does mechanical engineering relate to industrial design?

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.

Does mechanical engineering feed into manufacturing support?

Yes. Mechanical engineering decisions are made with manufacture in mind from the start, feeding directly into manufacturing support.
