What Is Garolite G10/FR4?
Garolite G10/FR4 is one of the most versatile and widely used thermoset glass-reinforced laminate. It is made from an alkali-free electrical glass cloth that has been impregnated with an epoxy resin under the pressure and heat. The resulting glass-epoxy laminate is incredibly stable over temperature level with low-moisture absorption and a high strength-to-weight ratio.It is typically utilized in applications that requiredimensional stability, longevity, and resistance to humidity. It is made use of throughout a vast array of electric and mechanical applications.
JY Machinery can process G10/FR4 in a range of shapes and configurations to fulfill the requirements of your project.

CNC Machining FR4 G10 Material
Garolite parts can have typical characteristics such as a threaded hole that is ground rather than tapped. The external thread is turned on a lathe, or the thread is ground instead of using a mold. This is because if sufficient heat and pressure are generated parallel to the die, the laminate material is at risk of delamination.
JY Machinery, a leading manufacturer of customized Garolite machined components. We provide FR4 G10 drilling, milling, and machining services to either cut to size to or machined to your CAD drawings. From 5-axis machining centers to routers, we can quickly and easily cut your G10 FR4 to your exact specifications. The G10 FR4 sheet can be CNC machined to +-. 002" tolerance. And more accurate tolerances can be provided upon request.

The Surface Finish of G10 FR4 parts
Garolite parts are usually finished with a smooth touch, with a matte surface. Depending on the cutting path, the texture of the material can be obvious. In particular, due to the gradual transition of the cross section between layers, the texture of the anti-groove will appear lighter than other parts. G-10 FR4 part will not hold polished without secondary coating.
Other Garolite Phenolics
G10/FR4 is just one of the phenolic laminates we work with. Other Garolite materials available for your project include:
G5/G9 This basic purpose quality phenolic material is recognized for its woven glass melamine resin.
G7 This phenolic alternative includes a woven glass silicone resin and, consequently, is a general function quality material.
G11-FR5 G11 materials feature a commercial fibre glass composite laminate and an epoxy resin binder. The additional designation of FR5 indicates that this is the brominated, fire resistant variation of routine G11 materials.
GPO-1 This particular phenolic material is comprised of an arbitrary weave glass that is coupled with a polyester resin. It is taken into consideration to be a general purpose grade material.
GPO-3This is really comparable to GP01 because it additionally includes a random weave glass, however it is coupled with polyester-- not a polyester resin. It, also, is a basic function quality material.
If you’d like to find out more information about these or other related CNC phenolics terms, or if you just have additional questions you’d like to discuss with someone in a bit more detail, please don’t delay – contact JY Machinery today.
Potential Applications
The characteristics of G10/FR4 make it an ideal choice for complex and high-precision electrical insulator sub-projects. Electrical insulators limit the flow of current and provide protection for those who come into contact with them, while ensuring circuit integrity and product structural integrity.
Some of the many products that use G10/FR4 material include:
- Terminal boards
- Washers
- Sleeves
- Structural components
- Cryogenic components
- Wear applications
- Electrical applications
- PCBs – Printed circuit boards
- Power generation
- G10 knife handles
- G10 gun handles
- G10 grip materials
