DFM is a blend of science, technology and design experience. Hymid offers the perfect combination.

Prior to beginning the tool design and manufacture, the component design must be optimised. Not only does this process ensure it is possible to manufacture the part, but it also reduces certain inefficiencies such as long cycle times, material waste and low yield rates – all influencing the part cost. Further improvements can often be made to cosmetic standards, dimensional stability and batch consistency.

We understand injection moulding intimately, and use our skills to maximise component mouldability, minimise second operations, reduce assembly times and simplify tooling – adding value at every stage. Clients come to us for our multi-shot capability, but we’ll look at all the options because this may not always be the optimum approach.

Design for manufacture in practice

You’ll know what you want to achieve, and we’ll be thinking about the factors that affect product outcomes. Our focus will be on developing a viable product that meets your commercial and technical criteria, along with any other production limitations.

Our detailed technical approach includes defining product design requirements for injection mould tooling and includes some basic elements such as:

  • Wall section consistency and material flow paths
  • Draft angles, ensuring the part will release successfully from the mould
  • Feed systems, runner styles, and gate locations

We are also able to offer more advanced solutions where necessary, such as:

  • Thermal analysis and temperature regulation
  • Complex tool functionality / part design, such as collapsing cores and unscrewing mechanisms
  • Flow analysis and optimisation

For the latter, we utilise powerful mould flow software to ensure you can move effortlessly into higher volume injection moulding whilst optimising key efficiencies.

A fully considered approach to product viability

Our process also considers the full product or component specification, such as:

  • polymer and elastomer selection
  • unusual additives, such as antimicrobial, static dissipation or laser marking
  • environmental processes, sustainable bio-polymers and optimisation for recycling
  • resistance to unusual contaminants, UV light or chemical exposure
  • compatibility with paint, adhesive or solvents
  • legal compliance e.g. medical cleanroom standards, ATEX approval or DIN standardisation
  • life expectancy and durability under specific conditions

Your next steps

If you have designs or CAD files, then speak to us now. We help clients at the earliest design stage and throughout the product development life cycle, and can help with part or all of the process.
