Plunkett Associates machine, mould, bend, press and additively manufacture in the part quantities that you require. With design experience to optimise for the process, we are here to meet your timescales efficiently. Contact us for all Prototyping, Tooling and Moulding requirements.


Plunkett Associates supply Plastic, Metal, Clear and Flexible parts through a range of technologies, including Injection Moulding, Compression Moulding, Vacuum Casting, CNC Machining plus all Additive Manufacture options.

As specialists in low volume injection moulding, we have the expertise and capacity to run a variety of tools from hand-loaded development tools to fully automatic production tooling, all in a wide variety of materials.

Using a range of standard tooling bolsters, we help reduce customer costs and address tight lead times, and by using Moldflow analysis, enables us to identify potential design issues ahead of tool design. Hence whether you need 10 parts or a batch of 100,000, we can supply tooling and parts for your application to your timescale.


Whilst injection moulding is the end product, the tooling is the first thing to resolve. We offer:

Development Tooling: There are times when product development can only take place on components produced in production-intent materials. Manufacturing tooling at this early stage in a development programme is high risk as the design is immature and changes are likely to be required.

We have the experience and expertise to create development tooling quickly and factor in potential changes so that they can be realised with the minimum of delay. This facilitates either the creation of several options or the iterative tuning of a part to achieve your design goal.

Rapid/Prototype Tooling: This class of tooling is driven by the need for speed! This is achieved through standardisation where possible and the use of loose inserts, if applicable, to resolve undercut features. We regularly use prototype tooling to produce injection moulded parts in quantities ranging from sub-one hundred to low thousands.

Bridge tooling: This came about initially to ‘bridge’ the gap between prototype and production, however today we commonly use this as a low volume production tool with great success. Addressing the need for a cosmetic finish, injection moulded materials and a short lead time, bridge tooling can be invoked as a low volume production tool.

Note: utilising Figure 4 and its wide range of production-grade materials including ABS and PP ‘like’, high temperature and flame retardant, we can offer 3D printed parts that are fit for end-use. This allows the customer to receive parts from Day 1 whilst the injection mould tooling is manufactured.

Production tooling: Production Tooling is manufactured in a wide range of tool steels including ABS, PC, ABS/PC, PA, PAGF, Ultem, and PVC to name a few. Production call-off can be scheduled and shipped as required worldwide.


Plunkett Associates’ sister company, Adept Precision, based in Gloucester, offers a range of injection moulding and tooling services. Manufacturing tooling in aluminium and steel, with qualified, highly skilled Toolmakers and Moulders, will match your requirement with the appropriate tooling in order to deliver a viable moulded solution.

Set up to offer a bespoke UK service for fast-track requirements, Adept Precision are managed by Plunkett Associates and can be contacted through them.
