PC GF30

PC GF30 is a 30% glass fiber reinforced polycarbonate that offers a significant leap in mechanical performance compared to standard unfilled grades. By incorporating glass fibers, this material achieves exceptional rigidity, high tensile strength, and a drastically reduced thermal expansion coefficient. It maintains the inherent impact resistance and flame retardancy of polycarbonate while providing the structural integrity required for heavy-duty industrial housings. At Jucheng Precision, we specialize in the high-tolerance CNC machining of this abrasive reinforced polymer. Utilizing advanced diamond-coated tooling and rigid machine setups, we deliver precision-engineered PC GF30 components that excel in demanding structural applications within the automotive, electrical, and industrial sectors.

PC GF30 Machining Capabilities

Capacité	Description technique	Avantage Jucheng
Fraisage résistant à l'abrasion	The 30% glass fiber content is highly abrasive. We utilize diamond-coated (CVD) or sub-micrograin carbide cutters.	Ensures consistent dimensions and sharp edges over long production runs by preventing tool blunting.
Usinage structurel rigide	Leveraging PC GF30’s high modulus to machine thin-walled structural housings that maintain their shape.	Our 5-axis machines achieve tight tolerances (+/- 0.02mm), preventing the part flexing common in unfilled plastics.
Alésage et alésage de précision	Creating accurate bearing seats and fastener holes in reinforced polycarbonate.	Specialized reaming strategies prevent glass fiber “tear-out,” ensuring perfectly smooth internal diameters and secure fits.
Finition à grande vitesse	Optimized tool paths to achieve a clean matte finish without the “fuzzy” surface common with filled plastics.	Delivers professional, industrial-grade aesthetics directly off the machine for visible structural components.

Fabrication Guidelines for PC GF30

Gestion de l'abrasivité :
PC GF30 wears down standard tools rapidly. Conseil : We frequently monitor tool life and use automated compensation to ensure “size drift” does not occur during large batch production.

Non-Transparent Nature:
Adding glass fiber makes the PC opaque (usually grey or black). Conseil : This grade cannot be polished to transparency. Design for mechanical performance rather than optical clarity.

Comportement fragile :
Reinforced PC is more brittle than standard polycarbonate. Conseil : We avoid sharp internal corners and use generous radii to prevent stress concentrations that could lead to cracking under structural load.

Chemical Sensitivity:
Like all polycarbonates, GF30 is sensitive to certain oils and solvents. Conseil : We use strictly compatible, water-soluble coolants to prevent chemical stress cracking (crazing).
