How to Choose the Right AS9100D Machine Shop for Your Needs
Start by matching the shop's material expertise to your most common part requirements. If you work with titanium or Inconel, prioritize shops like Moseys or Hogge that list those explicitly. Next, consider their delivery track record: a 99% on-time rate can save you from production delays. Finally, look for shops that offer secondary services like assembly or inventory management if you want a single-source partner. For local convenience, Three Rivers Precision in Pittsburgh offers certified quality without cross-country shipping.
Automating Your Quality Checks with Your Machine Shop Partner
Once you've selected a shop, set up automated data feeds from their inspection reports into your own quality management system. Many AS9100D shops provide CMM reports and certificates of conformance digitally. You can use those to automatically flag any deviations before parts hit your floor. This reduces manual inspection time and helps you catch issues early, keeping your scrap rates low.
Your Next Step Toward Lower Scrap Rates
High scrap rates and bottlenecks don't have to be your new normal. By partnering with an AS9100D certified machine shop, you gain a quality system designed to prevent defects before they happen. Whether you choose a national leader like Moseys or a local partner like Three Rivers Precision, the key is to align their capabilities with your specific production challenges. Start with a conversation about your toughest parts and see how they respond.
