Hi-Technology Group is a leading plastic injection moulding company with over 40 years of proven delivery. With facilities in Waterlooville, Letchworth and Slovakia, we provide reliable moulding for both technical low-volume parts and large-scale automated production.
Customers trust us for our engineering depth, full-service manufacturing and stable multi-site supply chain.
Founded in 1983, our business has grown from a specialist toolmaker into a multi-site group leading in precision plastic injection moulding. Over the years, we’ve invested in advanced automation, expanded internationally, and built an engineering team capable of supporting some of the most demanding sectors in the industry.
Our track record includes industry recognition from partners, including 3M (EMEA Supplier of the Year) and BD (Partner Supplier of the Year) — testament to our consistent delivery, responsiveness and exceptional customer support.
Waterlooville, UK
A technical hub focusing on moulding, assembly, welding and automated production cells.
Letchworth, UK
Enhanced capability following the acquisition of Sabre Plastics — increasing press capacity and expanding expertise.
Košice, Slovakia
A high-capacity European facility offering cost-optimised, large-volume production with press sizes ranging from 25–650 tonnes.
This structure allows customers to balance cost, complexity, volume, and risk – all under one unified group.
Where many injection moulders simply produce components, we support the full lifecycle, including:
Customers partner with us because we simplify supply chains, reduce operational burden, and provide long-term reliability.
For products requiring enhanced performance, multi-material function or component integration, we offer:
Insert moulding allows metal or pre-formed components to be embedded directly into the plastic during the moulding process. This creates a stronger, more reliable part while removing secondary assembly steps. Typical inserts include metal threads, bushings, pins, connectors and structural reinforcements.
Our engineering team works with customers to ensure proper insert design, alignment and bonding for long-term durability. Whether you need increased strength, improved connectivity or reduced assembly time, insert moulding provides a cost-effective, highly repeatable solution.
With multi-site capability and automated cell options, we support both technical low-volume projects and large-scale insert-moulding production with consistent quality.
Overmoulding allows two materials to be combined into one component by moulding a soft or secondary polymer over a rigid substrate. This improves grip, comfort, safety and product performance while eliminating additional assembly steps.
We provide TPE overmoulding onto substrates such as PP, PC/ABS and Nylon, supporting applications in medical devices, personal safety products, industrial tools and consumer goods. Our team ensures strong material compatibility, clean visual finishes and reliable long-term adhesion.
Overmoulding is ideal for adding ergonomic surfaces, vibration damping or colour-contrasting features, offering a practical way to enhance product functionality without increasing complexity.
These processes are ideal for medical devices, industrial components, hand tools, safety equipment and consumer products.
Many customers rely on us not only for moulding but for complete product assembly. We provide:
This integrated approach reduces the number of suppliers required, improving lead times, consistency and supply chain visibility.
Tooling quality determines production reliability. We support customers with:
Our collaborative tooling approach ensures reliability, repeatability and cost-efficiency over the full lifespan of the product.
We are progressing toward ISO 13485 and providing strong QMS foundations, documentation and traceability, essential for regulated markets.
A leading supplier of high-volume mouldings for safety and consumer protection products.
Trusted for precision components with strict compliance, testing and documentation expectations.
Hi-Technology Group operates robust processes to ensure consistency and reliability:
For decision-makers, this means reduced risk, predictable performance and confidence in long-term supply.
Decision-makers choose us because we offer confidence, technical assurance and continuity in an increasingly complex manufacturing landscape.
Whether you need prototypes, tooling, production, assembly or long-term volume manufacturing, we’re ready to support your project.
