Plastic Machining
Reliably, plastic machining since inception in 1989, Sentinel have always provided exceptional CNC Plastic Machining Services UK. Moreover, the company has a history of successful engineering plastic machining, but also, insulation plastic machining. Hence, a top UK experienced and exceptional services in plastic production. Also, it’s important to note, reliably having the ability to repeatedly accomplish tight tolerances. Furthermore, due to its many years of service, a great depth of knowledge when CNC milling and turning. Moreover, due to the huge variety of plastic materials available, this knowledge is invaluable.
CNC Machining Plastic Guide Solutions from Sentinel Plastics Ltd
Certainly, selecting a knowledgeable manufacturer for any plastic cnc machining requirements, is key to successful completion of a project. Undoubtedly, Plastics require specialized expertise to prevent expensive defects or product failures. Hence, only a dedicated plastics company can offer the right guidance. Thus, helping guide you through the complex catalogue of plastic materials available for selection.
Bespoke Plastic Parts Services
Without doubt, Sentinels popularity is due to always being at the forefront of plastic engineering capabilities. Justifiably, Considered by many, as one of the top plastic machining companies in the UK. In short, for machining quality Plastic components.
Moreover, having capability to manufacture parts from simple to highly complex shapes. Also, an extensive range of plastic machining services including CNC machining, cutting, routing, lathing, drilling and milling. Not least, a team of highly experienced engineers and CAD technology. Thus, enabling bespoke engineered components to your exact requirements. Certainly, We can manufacture single units or large quantities using a wide variety of engineering plastic materials from stock. Moreover, Quotations can be provided from either existing samples or drawings.
Quality Plastic Machining UK

Certainly, Quality machining plastic UK can be very different to working metals. Hence, can require a very different approach in terms of processes. Example, tool selection, cutting paths, numbers of passes, cutting speeds, pecking, reaming and multiple other factors. Also, Sentinel conducts many first-off inspections to ensure quality maintained in all components. Plastic machining services is tightly related to CNC prototyping art. Polymer materials are perfect for prototype creation and engineering validation. The reason for that is that plastics are actually quite easy to machine. If you don’t have any heating or molding equipment, manufacturing parts from CNC plastic blocks is a good way to get those prototypes easy and fast.
Ideally Located to Supply Plastic Requirements
Significantly, Sentinel is strategically positioned in the heart of the UK in the West Midlands. A valuable position for a business that supplies companies all over the UK and Europe. Markedly, Sentinel has clients in China and the USA as well as in the local vicinity.
Plastic Engineering Machining
Being more expensive, engineering plastics are produced in lower quantities and tend to be used for low-volume applications.
Moreover, the term usually refers to thermoplastic materials rather than thermosetting ones. Examples of engineering plastics include acrylonitrile butadiene styrene (ABS), used for car bumpers, dashboard trim and seating; polycarbonates, used in guarding; and polyamides (nylons), used for bushes and bearings.
Engineering plastics have gradually replaced traditional engineering materials such as wood or metal in many applications. Besides equalling or surpassing them in weight/strength and other properties. Engineering plastics are much easier to manufacture, especially in complicated shapes.
Engineering Plastics – Thermoplastic – Ref Wikipedia
A thermoplastic, or thermosoftening plastic, is a plastic machining material, a polymer, that becomes pliable or moldable above a specific temperature and solidifies upon cooling.
Quality Supplier Approvals
Importantly, the company is considered a high category supplier by many of its customers. Moreover, in supporting its clients, and the fluctuation in their build plans, Sentinel are operating many scheduled supply agreements. Which, will then allow them to call finished goods from stock. Also, these schedule supply agreements allow the company to optimise the manufacturing process. Notably, reducing the manufacturing costs, and, ensure the most efficient supply of finished parts to our customers.
Experienced Plastic Sheet CNC Machining
Further, our experienced machinists can produce small or large batch quantities with high accuracy and high speed, making this an economic form of producing cut to shape plastic parts. Customers from the Conveyor Manufacturer to the high tech world of underwater exploration use Sentinels skilled staff to gain benefits, including cost saving and problem solving during the design process.‘CNC’ means computer numerical control. A computer converts a design drawing into numbers using CAD (computer aided design) software. The numbers are used as coordinates, and the CNC machine uses these coordinates to control the movement of the cutter, and creates the shapes you require. The X, Y and Z axis control the movement of the machine, allowing material to be machined in 3 directions. Using this technology, our experienced machinists are able to produce custom shape plastic parts.
Plastic CNC Machining Help
Also, upon request, also able to assist you with the configuration and design of your machined plastic components. We know what different plastics can do and which types of processing are practicable from a technology perspective. As such, we provide you with the support from the selection of materials, to the design on the most advanced CAD systems. Finally, to the precise machining and customisation of a part that will function optimally for four application. Hence, whether you need any plastic prototyping or customized parts, fusing of complex components, or finishing and polishing services with low volume production. At Sentinel, we can offer advanced CNC prototyping services and high temperature and high-strength plastic machining materials.
