Design for manufacture

  • SURFACE ANALYSIS

    Surface analysis helps to guarantee the integrity of the external surfaces, particularly important on organic, highly polished surfaces

  • DRAFT ANALYSIS

    We undertake draft analysis of all injection moulded components to ensure the parts can be moulded reliably with minimal rejects.

  • MOULD FLOW ANALYSIS

    We determine the most suitable gate position to avoid visible weld-lines in the moulding and ensure parts are of the highest quality.

  • COMPONENT INSPECTION

    We produce full dimensioned component drawings with tolerances to ensure parts are manufactured to specification.

 Design for manufacture at Gm Design Development


Ensuring your designs meet manufacturing requirements

Gm Design Development has forged strong ties over the past 15 years with a number of manufacturers and works closely with them to ensure there are no unwanted surprises. It is a critical phase in any project, as well as often an expensive purchase for the client, so details need to be right to ensure expensive tool-re-work is avoided.

Working as one with the chosen manufacturer, we ensure the components are engineered to enable long-term, reliable manufacture. We agree in advance, the details of the Tool GA’s, specifying feed points, ejector pin positions and materials.

Our use of 3D CAD

3D CAD allows us to carry out full draft checks, component interference checks and mould flow analysis. We also produce detailed manufacturing specifications, to complement the 3D CAD data, such as detailed 2D component & assembly drawings.

Part analysis
Our CAD system allows for complete moulding analysis. We undertake full draft analysis of features to ensure they can be moulded successfully. Complex surfaces can be analysed, checking their curvature too, particularly important for highly reflective surfaces. Global interference checks are also carried out.

Component & Assembly drawing
Generate component and assembly 2D engineering drawings, fully dimensioned with tolerances to support the 3D data being issued.

Manufacturer selection
With over 20 years of experience working with toolmakers, moulders and manufacturers, our experience and knowledge enables us to advise you and guide you through the selection process. We have experience with dealing with both UK and Far East manufacturers.

Management of tool design
During the tool design process, we will work directly with the toolmakers, ensuring the tool design meets our requirements, ensuring gate and ejector pin positions are feasible and not on critical surfaces.

Drawing / part control
Part revision control is extremely important, particularly when developing medical devices. We maintain full drawing control throughout the development process.

Manufacture
We have experience working with specialist medical device manufacturers, as well as working with manufacturers around the world, from the UK to China. We can advise you on an appropriate manufacturer choice and production strategy.

Production planning / implementation
We can plan the production of your product. We work with several specialist companies. For electronic products, we work with electronic manufacturers who not only produce your PCBs but will also assemble your electronic product. For medical devices, we work with companies who can assemble your product in cleanrooms, pack and sterilise your medical devices.
