We offer fully integrated tool making and injection moulding services, built to complement our fast-turnaround prototyping and production capabilities.
Designed and manufactured entirely in the UK, our tooling and moulding services are ideal for companies seeking accuracy, speed, and control, especially in bio and life science R&D.
Whether you’re launching a new product, refining a prototype, or scaling to low-volume production, we can support you at every stage of development.
UK tooling, designed and built in-house: All injection mould tools are designed and manufactured in the UK. This gives you full control, fast lead times, and clear communication throughout your project. It’s especially valuable if you’re working within UK compliance or regulatory requirements.
Ideal for R&D in bio and life sciences: We are a trusted partner for R&D teams, particularly in the biotech, diagnostics, and medical device sectors, where speed and accuracy are key. Our team works closely with you to support early-stage design, clinical validation and pilot production.
Integrated with your prototyping workflow: As a long-established provider of rapid prototyping, 3D printing, and CNC machining, our injection moulding service fits naturally into the end-to-end development workflow, making us the ideal partner for fast-moving innovation projects.
Your development partner: At Prototype Projects, we do more than manufacture, we collaborate. We are your development partner, working alongside your engineers, designers, and project leads to ensure the best outcomes from the earliest concept through to final production.
Our experienced team contributes strategic insight on material selection, design for manufacture, tooling optimisation, and production readiness. We help you reduce risk, increase speed to market, and develop smarter solutions for even the most complex challenges.
Production & low-volume runs: Ideal for pilot production, clinical validation, or bridging to full-scale manufacture.
Insert moulding and overmoulding: Multi-material options to improve mechanical and functional performance.
Post-mould assembly: Final component assembly in-house for a complete manufacturing solution.
Tooling options: Aluminium, pre-toughened or fully hardened steel, designed for speed, repeatability, and longevity, manufactured entirely in the UK.
We offer tool design, tool manufacture, injection moulding, 3D printing, CNC machining and vacuum casting under one roof. This joined-up approach gives you a single point of contact and full visibility throughout development. It also means faster lead times and fewer hold-ups.
Our UK-based injection moulding and tooling service is responsive and flexible, especially for projects in regulated industries like healthcare, biotechnology, and instrumentation.
We are accredited to ISO 9001:2015 for quality management and ISO 14001:2015 for environmental responsibility, ensuring consistent, sustainable manufacturing.
We primarily mould components in Polypropylene (PP), a popular choice in the life sciences sector due to its excellent chemical resistance and flexibility. However, we also work with a wide range of thermoplastics to suit different applications, including:
ABS (Acrylonitrile Butadiene Styrene): Strong, impact-resistant and ideal for durable, rigid parts.
PA6 (Nylon 6): Tough, wear-resistant and suitable for mechanical components.
PC (Polycarbonate): High strength and clarity, often used for enclosures and covers.
Glass-Filled (GF) and Flame-Retardant (FR) variants: For enhanced strength, stiffness or fire safety performance.
If you’re unsure which material is best for your application, we’ll help you identify the right option. Contact us to discuss the full range of thermoplastics we can source and mould.
Our in-house toolroom is equipped with modern CNC machining technology for the fast, accurate production of mould tools. We support injection moulding from as little as 1 gram shot weight, making it ideal for low-volume production, pilot runs, and the transition from prototyping to full-scale manufacture.
If you need a UK partner for injection moulding, whether for a prototype, short production run or fully assembled component, we’re ready to help.
Get in touch to discuss your project with our team, or to book a tour.
