Frequently Asked Questions (FAQs)

What is G10 material and why is it commonly machined in China?

G10 material, also known as FR4, is a thermosetting industrial laminate made from continuous filament glass cloth and an epoxy resin binder. It is highly valued for its excellent electrical insulation properties, mechanical strength, and low moisture absorption rate. Chinese factories often machine G10 due to its widespread use in electrical, aerospace, automotive, and other industries where high temperature stability and electrical isolation are crucial.

What are the typical machining services available for G10 material in Chinese factories?

Chinese factories offer a range of machining services for G10 material, including CNC milling, turning, cutting, and grinding. These services enable the production of complex prototypes and large series of precision-machined parts. The factories are equipped to handle various dimensions and thicknesses of G10 sheets, ensuring high precision and quality in the final products.

What are the key properties of G10 material that affect its machining?

G10 material has several key properties that affect its machining. It has a high density and specific gravity, excellent mechanical strength, and low water absorption. The material also exhibits stable electrical insulating properties and good processability, including punching, drilling, and cutting. However, it can generate heat and produce a nasty powder during machining, so proper cooling and dust management are essential.

What tools and techniques are recommended for machining G10 material effectively?

For effective machining of G10 material, you may need specialized tools such as diamond-coated bits or high-quality carbide tools. Using a diamond-coated bit, especially for cutting, can significantly improve tool life and performance. For drilling, high-speed steel (HSS) drills with compressed air cooling are recommended. It’s also important to maintain high RPMs (e.g., 4,000 RPM) and moderate feed rates (e.g., 20 ipm) to avoid excessive heat buildup.

How do Chinese factories ensure the quality and precision of machined G10 parts?

Chinese factories that machine G10 material often adhere to strict quality standards. Many of these factories are ISO 9001:2015 and AS9100D certified, ensuring that the machining processes meet international standards. They use advanced CNC machinery and employ skilled technicians to ensure precision and quality in the final products. Additionally, these factories provide customized services based on customer drawings and specifications to meet specific industry requirements.
