Preguntas frecuentes (FAQ)<\/h2>\n
\n
\n
Q: Why is Polystyrene prone to cracking during CNC machining, and how does AluCarbon Tech resolve this?<\/div>\n
A: GPPS is highly brittle and possesses low thermal conductivity. High cutting friction easily generates heat, which causes localized thermal stress, micro-cracking, and a phenomena called 'crazing' (fine surface cracks). AluCarbon Tech completely resolves this by utilizing ultra-sharp, high-rake carbide or polished diamond tools running at optimized feed-rates, paired with a constant high-pressure cold dry air blast. This avoids heat generation and evacuates chips immediately, producing a flawless crystal-clear edge finish.<\/div>\n<\/div>\n
\n
Q: What is the main difference between GPPS and HIPS from a machining perspective?<\/div>\n
A: GPPS is crystal clear but extremely brittle, meaning it requires meticulous toolpath feed controls to avoid shattering during deep milling or drilling. HIPS is modified with rubber, which makes it opaque but significantly tougher and highly ductile. HIPS machines exceptionally smoothly like a standard engineering plastic, making it ideal for robust structural chassis prototypes and structural enclosures.<\/div>\n<\/div>\n
\n
Q: Can CNC machined Polystyrene components achieve an optical-grade finish?<\/div>\n
A: Yes. For GPPS components requiring light transmission or clear fluid tracking, we utilize high-precision single-point diamond turning (SPDT) and specialized post-machining vapor polishing or diamond compound buffing techniques to restore absolute transparency and eliminate microscopic tool marks.<\/div>\n<\/div>\n
\n
Q: Do you enforce minimum order quantities (MOQ) for custom engineered Polystyrene parts?<\/div>\n
A: AluCarbon Tech supports design and engineering teams globally with zero MOQ limitations. We smoothly process everything from a single high-clarity optical prototype for testing up to high-volume commercial production runs exceeding 1,000+ custom batches.<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
