Design Services

For organisations that have chosen to partner with us through a development project, our design stages translate all of the gathered engineering knowledge into the data needed to enable the manufacture of production parts and assemblies. Equally, we can support all organisations, large and small, with these same services.

3D CAD Modelling

Products, assemblies, sub-assemblies and parts will all start off as 3D CAD models, that will later become transferred to 2D drawings that can be used to manufacture something to a specification. Here, at PDE, we can create the 3D models you need across a range of widely used CAD packages such as Autodesk Inventor, Solidworks and Solid Edge, and provide the output of these packages across an expanded range of other formats, including neutral ones.

2D CAD Drawings

Your product will include individual components that need to be made as well as one or more assembly operations to put together the finished item. During the course of your project, you may need to go through a few loops of Design/Make/Refine. At PDE we can create the documentation at every stage so that all of your individual parts can be manufactured and all of your build steps can be specified with the the right level of the right type of instruction. We can help you with tolerancing, both dimensional and geometric (GD&T), so that every piece of your project has value optimised and waste minimised from the start.

We can create native CAD output in Autodesk Inventor, Solidworks and Solid Edge, as well as exports across a range of formats, including PDF, and we can do this for items produced across a wide spectrum of processing routes, such as machining, casting, fabrication, etc.

Material and Process Selection

For start-up organisations in particular, knowing what characteristics individual parts of your product should be made from can be a daunting task. A part may have particular strength, stiffness or life requirements that are best suited to our Life/Reliability analysis services upfront to guide you. Similarly, you may need it to have some minimum or maximum hardness, to have particular friction characteristics when considered to be running against something else, or to satisfy a particular environmental specification to be aligned with an international standard of some sort that you need to comply with to be able to pitch your product in one of your target markets.

There is an almost inexhaustible list of options for materials, and something similar for additional processes that can be used to alter their key characteristics, and we can help you carry out the most appropriate investigations to enable your final product to have the right choices applied to its constituent parts.

Additive Manufacturing

An especially useful approach for prototyping that also has a great many applications for production items if the economics work, Additive Manufacturing refers to a whole suite of processes that relate very closely to what the layperson would think of as 3D printing; the building up of items layer by layer, rather than traditional casting, extruding, machining, etc.


We can work with you both in terms of the 3D models to feed into the additive process you wish to use and to advise on the stereolithography, sintering or melting processes that are most suitably aligned to what you need to achieve.
