I'm seeking a reliable manufacturing partner for two custom stainless steel products. The first product requires specific dimensions and features, including a threaded cap and housing for a sensor, finished with bead blasting. The second product involves multiple engravings and PVD black titanium coating, along with additional hardware. Looking for competitive pricing, consistent quality, and in-house capabilities for the coating process. A sample order prior to full production is essential to ensure everything meets our standards. Please provide your best unit price, MOQ, lead time, and sample costs. I can send the necessary 3D files and technical drawings.
