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

القدرة الوصف الفني ميزة Jucheng
تفريز مقاوم للكشط 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.
التشغيل الهيكلي الصلب 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.
التجويف والتوسيع الدقيق 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.
التشطيب عالي السرعة 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

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

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