H\u00e4ufig gestellte Fragen (FAQ)<\/h2>\n
\n
\n
Q: Why is Polycarbonate susceptible to cracking during CNC machining, and how does AluCarbon Tech mitigate this?<\/div>\n
A: Polycarbonate is an amorphous plastic, meaning it is highly sensitive to residual localized stresses caused by heat buildup and aggressive cutting forces. Standard machining easily induces micro-crazing and sudden stress-cracking, particularly around deep drilled holes or sharp internal corners. AluCarbon Tech prevents this by strictly using sharp, polished, low-friction carbide tools running at optimized speeds to reduce cutting heat. We also introduce specialized water-soluble, non-solvent coolants and implement post-machining stress-relief annealing procedures, entirely eliminating internal stress and guaranteeing structural integrity.<\/div>\n<\/div>\n
\n
Q: How can I restore the transparent clarity of Polycarbonate parts after CNC milling?<\/div>\n
A: CNC milling leaves a matte, frosted finish on the surface. To achieve glass-like optical clarity, we provide professional in-house post-processing solutions. Depending on the geometry, we use Vapor Polishing (utilizing a solvent gas to reflow outer microscopic valleys for complex internal manifolds) or Diamond Fluid Polishing (for outer cosmetic faces and flat shields), reaching up to 85%+ structural light transmittance.<\/div>\n<\/div>\n
\n
Q: Which materials are chemically incompatible with machined Polycarbonate parts?<\/div>\n
A: Polycarbonate is vulnerable to chemical degradation from strong organic solvents, aromatic hydrocarbons, alkalis, and specialized ester cleaning chemicals, which cause rapid surface fogging and micro-cracking. For environments involving severe exposure to industrial chemical agents, we recommend checking compatibility tables or evaluating chemically passivated plastics like PTFE or PEEK.<\/div>\n<\/div>\n
\n
Q: What is your Minimum Order Quantity (MOQ) for custom precision Polycarbonate parts?<\/div>\n
A: AluCarbon Tech provides flexible production support globally with zero MOQ restrictions. We accept single-piece optical transparency prototyping for R&D evaluation and possess the capacity to smoothly scale up to mass production lots exceeding 1,000+ custom industrial parts.<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
