Yet the part still fails. Why? Because some plastics absorb moisture from the air long before they reach the molding machine. 🔍 Which materials are sensitive to moisture? Many engineering plastics are hygroscopic, meaning they absorb water from the environment: 💧 PA (Nylon) 💧 PC (Polycarbonate) 💧 PBT 💧 PET 💧 ABS/PC blends Even a small amount of moisture can significantly affect the molding process. ⚠️ What happens if material is not dried properly? Common defects include: ❌ Silver streaks on the surface ❌ Bubbles or voids ❌ Reduced mechanical strength ❌ Poor dimensional stability ❌ Increased scrap rates In some cases, the material begins to degrade during processing. 💡 Why drying matters Proper drying ensures: ✅ Bet...
