- [Why Extrusion and Injection Molding Cannot Use the Same Material Selection Logic](https://polymaro.com/blog/extrusion-vs-injection-material-selection-logic/): At first glance, extrusion and injection molding may seem to ask for the same thing: a plastic that flows well and meets the part’s performance target.
- [Which Plastic Molding Surface Defects Are Material-Related? A Practical Guide to Flowering, Silver Streaks, and Flow Marks](https://polymaro.com/blog/plastic-molding-surface-defect-material-guide/): When molded parts show flowering, silver streaks, or flow marks, the first reaction is often to blame the mold or the machine.
- [Plastic Part Cracking Analysis](https://polymaro.com/blog/plastic-part-cracking-analysis-root-cause-diagnosis/): When a molded plastic part cracks in the field, the fastest way to reduce scrap, warranty risk, and repeat failures is to stop asking only “what broke” and start asking “why did it break here, now, and in this way?” In plastic part cracking analysis, the root cause usually falls into one of three buckets: material toughness limits, stress concentration or overload, and environmental attack that turns a normally acceptable design into a crack-prone one.
- [Why Glass Fiber Reinforced Plastics Are More Prone to Warpage and Appearance Defects](https://polymaro.com/blog/glass-fiber-reinforced-plastic-warpage-appearance-defects/): Glass fiber reinforcement is often chosen when a plastic part needs more stiffness, higher heat resistance, or better load-bearing performance.
