Nylon Injection Molding FAQ
Expert answers to common questions about nylon material selection and manufacturing
For Engineers
Should I use PA6 or PA66 for my application?
PA66 offers 20-30% higher strength, stiffness, and heat resistance (HDT 260°C vs 190°C) but is more difficult to process. PA6 is more impact resistant, easier to flow, and better for thin walls. PA66 is preferred for automotive under-hood; PA6 for consumer products and gears.
What are the moisture absorption effects on nylon parts?
Nylon absorbs 1-3% moisture, causing dimensional changes and property shifts. Dried nylon (0.1% moisture) is stiff and strong; conditioned nylon (2% moisture) is tougher but softer. We recommend conditioning parts to end-use environment before final dimensioning for critical applications.
What's the recommended wall thickness for nylon parts?
Recommended wall thickness is 1.5-3.0mm for nylon. PA6 flows well in thin sections (0.8mm minimum). Thicker walls increase cycle time and risk voids. Glass-filled nylon requires uniform wall thickness to prevent fiber orientation issues and warpage.
How does glass fiber reinforcement affect nylon properties?
Glass fiber increases tensile strength (up to 200% improvement), stiffness (2-3x), and heat resistance (HDT +50-80°C). However, it increases anisotropy (directional properties), reduces impact strength, and increases mold wear. We optimize glass content based on your requirements.
For Procurement
What nylon material brands do you source?
We source from BASF (Ultramid), DuPont (Zytel), Ascend (Vydyne), and DOMO (Technyl). All automotive-grade materials with full traceability. Glass-filled and specialty grades from certified suppliers. Can work with your preferred supplier.
What are the lead times for nylon tooling and parts?
Prototype molds: 7-15 days. Production molds: 3-5 weeks. Production parts: 2-3 weeks. Nylon requires careful drying which adds process time. Glass-filled molds may require hardened steel for longevity. Rush services available.
Do you offer food-grade nylon parts?
Yes, we offer FDA-compliant food contact grades (PA6 and PA66). Also available: NSF 61 certified for drinking water, and EU 10/2011 food contact compliant. Full traceability and lot-specific documentation provided.
What's your quality guarantee for nylon parts?
Parts meet specs or we replace free. 99.5% first-pass yield with moisture-controlled processing, incoming material verification, and dimensional SPC. Full PPAP support for automotive. Lot traceability from raw material to finished part.
