\n
\n
Q: Why is PET selected over Nylon or Delrin for high-moisture processing environments?<\/div>\n
A: Nylon absorbs considerable moisture over time, leading to significant dimensional swelling and a drop in mechanical properties. While Delrin is superior to Nylon, PET features near-zero water absorption and a significantly lower coefficient of thermal expansion, making it the premier choice for strict-tolerance applications where parts face continuous exposure to water or liquids.<\/div>\n<\/div>\n
\n
Q: What is the main advantage of choosing Ertalyte TX (Lubricated PET) for moving components?<\/div>\n
A: Ertalyte TX contains a uniformly dispersed solid lubricant. This drops its friction threshold even lower than unfilled PET or Delrin, eliminating the stick-slip effect and dramatically extending part life in unlubricated sliding wear tracks and rotating bush systems.<\/div>\n<\/div>\n
\n
Q: How does AluCarbon Tech control chip accumulation and surface scuffing when machining PET?<\/div>\n
A: PET can be relatively brittle and prone to surface marking if chips wrap around the tool. Our technical operators integrate high-speed, sharp, single-point carbide setups combined with constant high-pressure air blasts. This completely evacuates continuous plastic ribbons before they scuff the surface profile.<\/div>\n<\/div>\n
\n
Q: Do you enforce minimum order quantities (MOQ) for custom engineered PET parts?<\/div>\n
A: AluCarbon Tech supports engineering clients globally with zero MOQ limitations. We accommodate everything from single high-accuracy functional prototypes for line testing to serial commercial production exceeding 1,000+ custom batches.<\/div>\n<\/div>\n<\/div>","protected":false},"excerpt":{"rendered":"
