Plug and Moulds


Talking through a project early in its programme can often save time and money further down the line. Correct plug manufacture will ensure a better mould and subsequent ease in releasing mouldings.
Our team will work with designers to ensure the optimum mould design is achieved before manufacture starts. We can advise on different moulding techniques and in the choice of mould materials such as Vinylester, Polyester and Epoxy.

Mould Tools

Although MonsterCAM are a High Tech company using state-of-the-art equipment, our team all come from traditional Plug and Pattern Making backgrounds as we know that understanding the needs of the Mould Maker is crucial in Plug manufacture.
Increasingly, we are asked to provide directly machined moulds, suitable for development, pre-production or low-volume builds. This is now fully achievable with our MonsterCAM machining centre.
Large moulds are generally supplied with a steel framework bonded to the underside. These are fully painted and use heavy duty castors to ease mobility.

Resin Dispensing System (RDS)

Large plugs can be constructed from styrene blocks, machined to just below the 'A' surface onto which Epoxy paste is applied either by a controlled hand dispenser or by 5-axis application, the final 'A' surface is machined and prepared for finishing.


More clients now require quality suppliers to supply finished production parts, enabling them to save space and have parts delivered to coincide with their manufacturing programme. MonsterCAM's facilities give us the space to store moulds securely and deliver parts on time, when needed.

Hand Lay-up

Most mouldings are generally laid up by manually laying down layers of GRP and resin. Skill is required to achieve consistency of surface finish and overall material thickness. Where the 'B' surface is visual, RTM might be considered.


MonsterCAM can advise clients with Resin Transfer Moulding techniques. This process offers the ability to produce mouldings with a consistent material thickness and have a good 'A' and 'B' surface.
A 'closed moulding' process allowing mats and cores to be in place before resin is introduced into the mould before resin is added under vacuum. Again, we can advise clients wishing to use this process.
