G10 – FR4 Machining – Epoxy Glass Laminates

G10-FR4 Machining

Plastic Machining | Milling | Routing | Turning | Fabrication

Firstly, G10-FR4 materials are Epoxy Glass based Insulation Plastic. As such, these laminates generally offer high mechanical strength and dimensional stability. Also, extremely durable, and, maintain their properties wet or dry. Therefore, the result of this blend is a material that offers excellent ark and track resistance.

G10-FR4 Machining – Perfect for Milling

Certainly, The commonly known G10-FR4 are the most popular grades. Further, G10-FR4 glass cloth reinforced epoxy natural is a yellowish to light green color. In short, Epoxy resins are among the most versatile and widely used plastics in the electronics field. Primarily, because water absorption is virtually nil. Thus, rendering it an outstanding insulator.

Also, G10-FR4 machining material known for being the most economic choice of insulation. Also, for bespoke applications, it is a material which can be being easily machined.

Examples, G10-FR4 Materials are widely used to manufacture are Insulating supports, high voltage insulation, bus bar supports and mounting panels in electrical apparatus are just some.

Moreover, based on the needs of its particular application it comes in several grades.

In Sheet Form Machining

G10-Fr4 machining - FR4 Machining G10 - FR4 Machining - Machined G10 - FR4 Parts - Epoxy Glass Specialist

Further, there are many advantages to using G10-FR4 Machining Materials. In the main, its having high structural strength. But also, excellent Electrically Insulating properties.

G10-FR4 Turned Parts

Also, as with most laminates, raw materials are available in standard sheets & rod sizes.

Thus, Sheet thickness ranges from 0.8mm to 50mm.

G10-FR4 Machining of Bespoke Parts

Further, All parts manufactured by Sentinel Plastics Ltd are customer specific bespoke parts. Either, from working from Prototypes, to drawings or, the making one off to hundreds of parts. Importantly, Sentinel Plastics has flexibility to meet most requirements.

Moreover, epoxy material is nearly immune to shrinkage. Hence, holding its form factor and dimensional stability. Above all, at temperatures, as high as 285° F. Thus, this property makes it ideal for use in electronic equipment. With, components that generate excessive heat. Also, should it combust at higher temperatures, the bromine added during the manufacturing process, renders it self-extinguishing. In short, another important factor for making its use in aerospace engineering so prominent.

Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such as polystyrene, PVC, polypropylene and polyethylene). plastic machined parts.

A little more on Engineering Plastics

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 Lego bricks; polycarbonates, used in motorcycle helmets; and polyamides (nylons), used for skis and ski boots.

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.
