At Sentinel Plastics, we’re proud of the trust our customers place in us. Understanding each client’s unique requirements is central to our approach, allowing us to deliver innovative, flexible, and on-time solutions that truly meet their needs.

Our reputation is built on decades of expertise in plastic materials and precision machining, ensuring every component we produce upholds the highest standards of quality and reliability.

Driven by a passion for quality, we continually strive to improve, embracing new technologies and innovative methods across all our products and processes. This dedication to excellence is at the heart of everything we do and defines how we support our customers every day.

Machining industrial plastics requires a very different approach compared to working with metals. Every stage of the process — from tool selection and cutting paths to speeds, feeds, and finishing techniques — demands specialist knowledge and precision.

At Sentinel Plastics, our expertise ensures that each material is machined using the most appropriate methods to maintain dimensional accuracy and surface integrity. We carry out comprehensive first-off inspections on all components, guaranteeing consistent quality and complete confidence in every part we produce.

Sentinel Plastics specialises in the fabrication, machining, and sub-assembly of precision plastic components for a range of blue-chip clients, including those in the medical, specialist industrial, and high-end power control sectors. Our strong reputation is built on delivering accurate, high-quality components on schedule and at competitive prices.

Using advanced data-driven manufacturing systems, we maintain full traceability of every product throughout the production cycle, ensuring efficiency and accountability at every stage.

Our flexible workflows also support the assembly of complete component groups, allowing us to integrate additional elements such as threaded inserts, bearings, or other fittings during post-machining processes. This enables us to deliver ready-to-use assemblies that meet even the most demanding technical specifications.
