Mechanical engineering services

Mechanical engineering is where GX turns ideas into manufacturable products. It’s the discipline that takes a concept off the page, solves the practical challenges, and ensures every component, mechanism and assembly performs reliably in the real world.

What mechanical engineering means to us

Mechanical engineering at GX is hands‑on, detailed and commercially focused. It’s the work that transforms early concepts into solutions that can be built, tested and produced at scale. Our expert team specialise in developing mechanisms, designing components, selecting materials, executing engineering calculations and ensuring every part fits together with precision.

GX’s engineers work across plastics, metals and machined parts, designing everything from simple housings to complex moving assemblies. We consider tolerances, loads, thermal behaviour, ergonomics and long‑term reliability; the real‑world factors that determine whether a product succeeds once it leaves the CAD screen.

To support this, GX provides services such as mechanical product design, mechanism development, plastic and sheet‑metal design, CNC‑machined components, injection‑moulded parts, castings, extrusions, DFM, DFA, tolerance analysis, prototype development and production engineering.

Our mechanical engineering process

GX follows a structured engineering process that reduces risk and keeps development moving.

Icon Lightbulb

Understand

It begins with understanding the product’s requirements and constraints, moving into concept generation, CAD modelling and engineering calculations.

Icon Product Design

Review

All designs are reviewed, refined and prototyped, allowing the team to test performance and make improvements before committing to production.

Manufacture

Once the design is proven, GX supports clients through design for manufacture, supplier liaison and production preparation — ensuring the product moves smoothly from development into the real-world.

Our mechanical engineers have specialist expertise in these areas:

  • Conceptual and detail design
  • Finite element analysis
  • Thermodynamic analysis
  • Stress and vibration analysis
  • Air flow analysis
  • Fluid mechanic analysis
  • Impact resistance
  • Manufacturing equipment
  • High speed mechanisms
  • Pneumatic equipment
  • Hydraulic equipment
  • Optics
  • High speed mechanical dynamics analysis, value engineering, electromagnetic interference screening
  • IP ratings
  • International standards
  • Supervision of manufacture

Designed for manufacture from day one

Manufacture considerations are built into every design decision we make to guarantee that they are functional, reliable and cost-effective to produce, whether the requirement is low‑volume manufacturing or full‑scale production.

The team works with processes including injection moulding, CNC machining, sheet‑metal fabrication, vacuum forming, die casting, silicone moulding, rapid prototyping and both low‑ and high‑volume manufacture. This ensures products can be produced economically and without costly redesigns.

Engineering tools and technologies

GX uses professional‑grade tools such as SolidWorks, Creo, simulation software, rapid prototyping technologies, 3D scanning and CAD rendering. These tools support accuracy, repeatability and clear communication throughout development.

Mechanical engineering across multiple sectors

GX’s engineers have delivered products for medical devices, life sciences, industrial equipment, aerospace, automotive, utilities, consumer products, food production, security and energy. Each sector brings its own technical and regulatory demands, and GX adapts quickly to meet them.

Technical depth that builds trust

Mechanical engineering requires detailed technical understanding — and our capability includes:

  • Material selection
  • Stress analysis
  • Thermal considerations
  • Mechanism design
  • Gear systems
  • Bearings
  • Motion control
  • Structural integrity
  • Ergonomics
  • Reliability engineering
  • Product testing.

This depth of experience helps us to safeguard your product and ensure that when it reaches mass market it behave exactly as intended.

Core principles that guide every design

Mechanical engineering relies on established physical laws, material behaviour/limits and proven design standards to ensure products are safe, functional and ready for manufacture. At GX, these fundamentals shape every decision — from early concepts to production‑ready assemblies.

01

Design for Manufacturability (DFM)

02

Design for Assembly (DFA)

Simplifying part count and assembly steps reduces cost, improves reliability and speeds production.

03

Simplicity first

04

Standardisation

05

Respecting tolerances

Engineers across the industry follow a set of well‑established principles that help ensure products are safe, manufacturable and reliable. These include keeping designs simple, choosing appropriate materials, designing for safety, ensuring maintainability, standardising components, optimising efficiency, respecting tolerances, planning for sustainability and validating designs through testing and iteration.
