Welcome to Dudley Associates
Specialist Toolmaking and Moulding Services

As well as designing mould tooling, we offer full product design and development services as well as other prototyping techniques.
We have been closely involved with a large number of successful design projects, taking the initial concept through to the production supply of moulded parts or assemblies - ranging from single parts to suites of parts for both large corporations and private companies.
We operate several high end 3D CAD (computer aided design) packages and can accept data from all the major design platforms such as Catia, Solidworks, Ideas, Autocad, ProE, Step and Unigraphics. The most common file format we receive is IGS.
We benefit from prioritised technical back up from the worlds major polymer manufacturers and have access to the very latest polymers, and design and processing data.
Often we are asked to guide engineers or individuals through their choice of polymers, design, colours, additives, and handling in order to help reach the best specification for both manufacture and budget.
Please ask should you also be interested in the following additional specialist prototyping services:
- Stereolithography (SLA) - uses lasers to build up a resin model for basic fit & form appraisal – a very quick option if only a few parts are needed.
- Mould flow analysis – computer simulation used to optimise the design of a part.
- FEA (Finite Element Analysis) – used to mathematically model and analyse a part.
The following prototyping links are also recommended:
- Vacuum Casting - a process that allows for fast accurate polyurethane resin casting of complex prototype parts in both rigid and flexible materials and in a wide range of colours
- Reaction Injection (RIM) Moulding - an alternative system to vacuum casting for larger components and short run production, with fast turn around times.
- Zinc centrifugal casting - uses SLA models for the master form in a silicone mould to make a zinc cast part
- Prototype Foam Components - fast and accurate polyurethane foam mouldings of complex prototypes, large or small.
Our Client base and reputation speaks for itself and we hope we may have the opportunity to provide you with the same high level of service and technical ability.
