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

역량 기술 설명 Jucheng의 강점
내마모성 밀링 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.
Rigid Structural Machining 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.
Precision Boring & Reaming 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.
High-Speed Finishing 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

연마성 관리:
PC GF30 wears down standard tools rapidly. 팁: 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). 팁: This grade cannot be polished to transparency. Design for mechanical performance rather than optical clarity.

Brittle Behavior:
Reinforced PC is more brittle than standard polycarbonate. 팁: 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. 팁: We use strictly compatible, water-soluble coolants to prevent chemical stress cracking (crazing).
