Pentagon: putting the positivity into plastics manufacture
Get in touchWe offer a complete plastic injection moulding service from initial design to development and onto tooling, production, and post production support. Our team are highly experienced and dedicated, offering a plastic injection moulding service that is truly world leading. We are able to offer mould tooling solutions as well as repeat production of injection moulding components and thermoplastic moulding.
We have a range of cutting edge tools and technology at our disposal to deliver moulding and tooling. We work very closely with our customers to make sure we fulfil their requirements to the letter and beyond.
We operate two companies from our UK site, Pentagon Plastics Ltd and Pentagon Tooling Ltd, and have traded in the sector since 1972. The companies complement each other, operating as two supporting divisions in the plastics industry, specifically in the sectors of plastic injection moulding and tool manufacture.
Pentagon Tooling is a centre of excellence for mould tool servicing, repair, modification, pre-production development, and production mould tools.
Specialising in all forms of mould tool services, we provide extensive tooling services to our diverse customer base, spanning a wide range of industry sectors. This consists of complex multi-cavity tooling for industries including medical, aviation, caps & closure, and packaging markets, amongst others.
Pentagon delivers comprehensive mould tool manufacture and supports bespoke in-house moulding for a range of customers, as well as an outsourced service to other plastic injection moulders.
The technical expertise in our plastics division enables us to provide a wealth of knowledge and experience to a diverse customer base, spanning many different industries. Our services include design for manufacture, development, tool trials, low to medium volume repeat production, and post moulding operations. A wide range of injection mould tooling can be accommodated including basic development tools, single impression, and family moulds through to multi-cavity. Tools are processed on a range of clean, efficient, and well-maintained electric, hybrid, and hydraulic moulding machines.
Our post injection moulding services provide added value to customers and include finishing of parts, inserting, waxing, and light assembly. Specialist services such as painting, coating, and marking are subcontracted to approved suppliers.

Plastic injection moulding is a manufacturing process that involves melting plastic pellets and injecting them into a mould under high pressure. This process creates a wide range of plastic parts and products to exact specifications. The plastic is then cooled, solidified and, finally, the finished product is removed.
The process starts with a mould designed to the exact specifications of a product. The mould is designed with features like cavities, cores, and ejector pins before being mounted onto a plastic injection moulding machine. The plastic pellets are melted and then injected into the mould under high pressure to create the desired shape.
This process can be repeated thousands or millions of times, making it great for mass production of high-quality plastic products. Plastic injection moulding is widely used in industries like automotive, medical, electronics, and more.
Furthermore, there are different types of thermoplastics moulding and variations in the technical process that allow us to fulfil a wide range of product requirements. This includes the size of the press and the configuration of the mould tool.
At Pentagon, we have successfully manufactured many hundreds of parts including non-invasive medical, aircraft seating components, and electrical housings. Our expertise allows us to produce components across a range of industries and product requirements.
When deciding between plastic injection moulding and vacuum forming, it’s important to consider factors such as the complexity of the parts, the desired level of precision and accuracy, the production volume, and your budget.
Plastic injection moulding is generally more expensive due to the upfront costs. However, it offers the advantage of producing high-quality parts with consistent dimensions and minimal waste. Meanwhile, vacuum forming is a relatively inexpensive process, but it may not be able to produce parts with the same level of precision and accuracy as plastic injection moulding.
Ultimately, the decision between these two processes depends on the specific needs of the product being manufactured. In some cases, it may be necessary to use a combination of both to achieve the desired outcome.
Pentagon is unique in that, unlike our UK competitors, we provide mould tooling in-house from our facilities in Horsham, West Sussex. Not outsourcing production means we have direct on-site control over every element of a project.
We have been trading in the industry since 1972 and under the Pentagon name since 1979. Our many years of experience mean we understand the challenges and methods and have the know-how to take on and deliver any project. Whilst we have years of experience, we are also highly focused on keeping up to date on the latest tools and manufacturing methods.
We have worked on projects across a vast array of sectors over the years and our experience allows us to take on projects in new sectors with ease.
