PC GF30 Machining Capabilities<\/h3>\n\n\n\n\n\n\n\n\n
Capability<\/th>\nTechnical Description<\/th>\nJucheng Advantage<\/th>\n<\/tr>\n<\/thead>\n
Abrasive-Resistant Milling<\/strong><\/td>\nThe 30% glass fiber content is highly abrasive. We utilize diamond-coated (CVD) or sub-micrograin carbide cutters.<\/td>\nEnsures consistent dimensions and sharp edges over long production runs by preventing tool blunting.<\/td>\n<\/tr>\n
Rigid Structural Machining<\/strong><\/td>\nLeveraging PC GF30\u2019s high modulus to machine thin-walled structural housings that maintain their shape.<\/td>\nOur 5-axis machines achieve tight tolerances (+\/- 0.02mm), preventing the part flexing common in unfilled plastics.<\/td>\n<\/tr>\n
Precision Boring & Reaming<\/strong><\/td>\nCreating accurate bearing seats and fastener holes in reinforced polycarbonate.<\/td>\nSpecialized reaming strategies prevent glass fiber “tear-out,” ensuring perfectly smooth internal diameters and secure fits.<\/td>\n<\/tr>\n
High-Speed Finishing<\/strong><\/td>\nOptimized tool paths to achieve a clean matte finish without the “fuzzy” surface common with filled plastics.<\/td>\nDelivers professional, industrial-grade aesthetics directly off the machine for visible structural components.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Fabrication Guidelines for PC GF30<\/h3>\n

Abrasiveness Management:<\/strong>
\nPC GF30 wears down standard tools rapidly. Tip:<\/strong> We frequently monitor tool life and use automated compensation to ensure “size drift” does not occur during large batch production.<\/p>\n

Non-Transparent Nature:<\/strong>
\nAdding glass fiber makes the PC opaque (usually grey or black). Tip:<\/strong> This grade cannot be polished to transparency. Design for mechanical performance rather than optical clarity.<\/p>\n

Brittle Behavior:<\/strong>
\nReinforced PC is more brittle than standard polycarbonate. Tip:<\/strong> We avoid sharp internal corners and use generous radii to prevent stress concentrations that could lead to cracking under structural load.<\/p>\n

Chemical Sensitivity:<\/strong>
\nLike all polycarbonates, GF30 is sensitive to certain oils and solvents. Tip:<\/strong> We use strictly compatible, water-soluble coolants to prevent chemical stress cracking (crazing).<\/p>\n<\/div>\n

Primary Applications<\/h3>\n

Industrial Equipment<\/strong>
\nHeavy-duty structural brackets, mounting plates, and pump components requiring high rigidity and dimensional stability.<\/p>\n

Electrical & Electronics<\/strong>
\nHigh-load connector housings, circuit breaker components, and standoff insulators that must resist heat and impact.<\/p>\n
