ASA Injection Molding: Properties, Applications and Design Guide
ASA is used on injection molded programs when uv-stable styrenic for outdoor housings.

ASA vs ABS for outdoor housings
How procurement and design teams use ASA on injection molded programs.
ASA is used for outdoor housings that need a UV-stable styrenic. Buyers specify the commercial grade on the PO when known, or describe service temperature, chemical exposure, and mechanical targets so engineering can suggest a candidate resin. Quote with CAD and resin notes on the instant quote platform. NetProto builds one hardened steel tool with no minimum order quantity for production parts.
ASA vs ABS is the usual check for a weatherable plastic outdoor housing. ASA holds color under UV better than ABS, which is often used indoors. When UV stability is not the driver, see the ABS injection molding guide . Buyers comparing ASA injection molding suppliers still set the grade on the quote. If the part needs higher impact than a styrenic, PC/ABS is the next comparison.

ASA injection molding FAQ
When should I choose ASA?
Start with ASA when uv-stable styrenic for outdoor housings. Match the grade to temperature and chemical exposure on the TDS.
What is the difference between ASA and ABS?
ASA is the weatherable choice for an outdoor housing because it holds color under UV better than ABS. ABS is often used when the part stays indoors. Pick the grade from the supplier datasheet either way. Processing numbers stay on that datasheet.
Does this resin require drying?
Follow the supplier TDS for the exact grade. At NetProto, attach the datasheet when moisture-sensitive fillers are used.
What is the minimum order quantity for molded parts at NetProto?
NetProto has no minimum order quantity on molded parts from your production tool. Upload CAD on the instant quote platform to scope tooling and part pricing for your volume.
How do I quote this resin without a final grade selected?
List the resin family on the RFQ, attach environment and compliance notes, and upload CAD. At NetProto, engineers use DFM review to narrow grades before tooling release.
How fast can tooling start for a ASA part?
NetProto builds the hardened steel tool in about 10 business days on qualified programs, depending on part size and complexity. Upload CAD on the instant quote platform to start DFM review.
