60 Year heritage in Plastics

Rutland Plastics is a family owned plastic injection moulder with a reputation for a quality service and absolute reliability.  We are based in Rutland, East Midlands, UK and for more than 60 years we have worked in partnership with customers and suppliers across a diverse range of industries providing innovative and effective design, functional rapid prototypes, manufacturing and warehousing solutions.


We are known for our expertise in large and thick section mouldings up to 48kgs in weight and for our Gas Assisted Injection Moulding skills, and we have also developed our own electrofusion process for multiple applications.


We take great pride in our people, their technical expertise and know-how.  Sharing this knowledge with our partners and wider industry is at the heart of everything we do, combined with providing no obligation quotes, we trust demonstrates our confidence in delivering a superb service. 


In addition to injection moulding we offer a comprehensive range of services including engineering design, rapid prototypes, mould manufacture and a wide range of secondary operations: machining, assembly, ultrasonic welding, heat staking, gluing and warehousing solutions.

Quality Standards

We are Investors in People and hold the following accreditations ISO9001:2000 and ISO14001:2004 accredited. ISO13485 Medical Devices.


Plastics injection moulding requires a specific approach, and our expertise means you get the most suitable design from the outset.

We work with you to make the best choices of plastic materials and physical shape to result in optimum ease of production, cost efficiency and performance.

Working with us from the initial concept through to the injection moulding design stage using
3-D CAD, and finally to the making of the injection mould tool saves you time and money by eliminating the need to use expensive external design services.


We offer cost-effective mould-making through both in-house plastic mould and tool die manufacture as well as manufacture by subcontract toolmakers with whom we have long-established working relationships.

We manage subcontract tooling as in-house, and our experts only approve a subcontract injection mould when they are sure of optimum performance to our specifications. We also offer the option of overseas manufacture to UK specifications for suites of moulds or larger tools.

We provide free tool maintenance during the working life of all injection moulds manufactured by us or one of our partners while we are the appointed

In the event your plastic mould tool requires emergency attention, we can ensure minimum disruption to your production process thanks to our on-site facilities which allow us to make tooling modifications quickly and economically.


Our extensive range of modern injection moulding machines gives us the capacity to produce plastic mouldings weighing up to 48 Kg, with particular expertise in thick sections; in some cases in excess of 100 mm. This versatility enables us to meet most custom moulding requirements using cost-effective production methods.

Our computerised system provides full traceability and flexibility, allowing us to manufacture to order or work to schedules. We can offer the best price and maximum flexibility by manufacturing plastic mouldings in larger quantities, holding a balance in stock for call-off as required.

We produce plastic components for a wide variety of industries, so our injection mouldings are manufactured in many different thermoplastic materials, including prime or recycled / reprocessed, glass or talc-filled, or unfilled. Additives such as anti-microbials or flame retardants are available as well.


Our prototype service is often an essential part of the production process. It allows companies to test their products before committing to invest in costly mould tools. We use the Objet Connex 350 which is one of the world’s only 3D printers. More than 50 materials with varying mechanical properties, textures and shades can be achieved to simulate all kinds of results from rigid engineering plastics to transparent materials and more. High resolution prototypes with smooth surfaces and fine details are achieved and the maximum build size of any part is 342mm x 342mm (larger prototypes can be achieved by joining two smaller prototypes).

Additional Services

Machining or assembly with other components is often required to complete the manufacture of plastic injection mouldings. We have the capabilities and expertise to provide finishing touches such as multi-component assembly, trimming, sonic welding or machining to tight tolerances, eliminating the need to source a separate subcontractor. We may even be able to produce your complete product ready for onward shipment to your customer without further work or re-packaging in some cases.


We have patented an electrofusion manufacturing process that allows a simple and rapid method of joining plastics.

For example, in the case of joining water and gas pipes by electrofusion, we bury a lead-in wire under the coil winding used to fuse the pipe ends together when current is passed through. This reduces the risk of shorted wires during the welding process, which is a failure commonly associated with similar fittings.

We have also developed special sleeve bonding systems for joining insulated pipes as well as fittings that permit flanges to be joined to the sides of plastic vessels.

Gas Assisted Moulding

Gas Assisted Injection Moulding (GAM) is a relatively new plastics injection moulding technology in that offers opportunities to reduce costs and improve the quality and appearance of injection moulded components.

In GAM, pressurised nitrogen is introduced to the mould cavity at a set time during the moulding cycle. Cost reductions are realised due to reduced material quantity and production cycle times, as well as the ability to use single moulds and a smaller moulding machine. Finished products have fewer flow marks, reduced distortion and sink marks are eliminated.

GAM allows designers to use more imagination in the creation of injection mounded components as variable thickness sections can be included, and several components can be combined on a single part.

Injection Moulding Process

The manufacturing process of injection moulding is used for thermoplastic and thermosetting plastic materials. The process includes the following steps: Clamping, Injection, Dwelling, Cooling, Opening, and Ejection. Melted plastic granules are injected under pressure to fill a mould. When the plastic moulding has cooled it is opened to release the item inside. Injection moulding can be used for an extensive range of items from the smallest components to the entire body panels of cars.  The process is excellent for large batch runs of items to be produced quickly and accurately.

Medical Moulding

Our injection moulding services can include the production of medical components. We have a wealth of experience within this area and are also ISO13485 accredited. We pride ourselves in offering fully comprehensive injection moulding services, which includes design support, consultation and manufacture as well as assembly and machining. To find out more about any of our products and services please visit the website, alternatively you can contact our customer service team directly. 

Large & Thick Section Moulding

We can provide specialist large and thick section injection mouldings with sizes of up to 1mavailable. Although it can be difficult producing larger mouldings, we have found that utilising materials such as polypropylene and polyethylene are best suited for the task. It is also worth noting that unlike many other companies, we have more than one large moulding machine and are therefore equipped to handle a wide range of orders. If you would like further information please visit the website. 

Plant List

Our extensive range of modern micro-processor controlled injection moulding machines, many with robots, are supported by up-to-date plastic moulding techniques.

This means quicker tool changes and the efficient production of consistently high quality plastic components. Whether you require a small plastic part weighing only a few grams or a complex component weighing several kilograms, we can provide a cost-effective plastic injection moulded solution.

Design Guide

Our customers often have questions regarding the basic design rules that apply to plastic injection moulded parts and so we’ve developed a handy guide that aims to answer the most frequent questions we’re asked and prevent common errors, thus making the whole process more efficient. Go to our website and order your copy today and find out all you need to know about strength, precision, appearance and assembly and use the handy checklist on your next project.


VISI Flow software allows us to create simulations of a specific injection moulding process. This means we can gather important information on costing and design prior to manufacture. VISI Flow therefore allows to ascertain the ideal conditions for injection moulding and replicate these conditions for our customers. The software can also help us to predict issues such as warping and rectify this before product is made. If you have any further questions feel free to contact us by phone or email. 

Tool Transfer

We have seen an influx of tool production moving back to UK due to issues such as quality and costing. Whether you are moving your tool production from another country or even just within the UK itself, we can help. Customers can visit the website to view our full tool transfer procedure which includes advice on the best way to handle the process. If you would like to discuss your options further don't hesitate to contact our customer service team directly and they will do everything they can to help.
