Plastic MachiningMilling | RoutingTurningFabrication

Significantly, Sentinel is well known for being both, Tufnol CNC Machined Phenolic Epoxy Machining Specialists, as well as all other engineering plastic materials. Arguably, we believe, the highest quality machinists in this field. The machining from Sentinels Milling and Turning sections is, the envy of most competitors. So, see for yourself. The image is a great example of what can be achieved, when you have the experience in CNC milling Tufnol type materials.

Importantly, this particular part is destined for usage in the engineering electrical power sector. Ultimately, this is where the largest demand for sentinels quality machined parts is required.

Tufnol Machining Specialists

It’s worth noting, Tufnol phenolic cotton materials are the workhorse grades for electrical and general mechanical applications. Furthermore, they are strong and tough with very good wear resistance and they are easy to machine into finished components.

Also, Tufnol Sheets are available with cotton fabric reinforcements, ranging from fine weave to coarse. And so, in general, the medium to coarse wave grades are used for larger and more rugged components, requiring good all-round strength and toughness. Similarly, the finer tufnol fabric grades are chosen for their superior finish, higher dimensional stability and improved strength in thin sections.

Please note, the electrical properties tend to be superior in the finer weave grades, but, the range includes a medium fabric weave. Hence, it has, enhanced electrical properties, suitable for electromechanical application. Finally, the two most widely used tufnol cotton fabric grades are Carp Brand and Whale Brand.
