I'd like to inquire whether your company offers coating services for parts using black chromium oxide. We're interested in understanding if you only supply the raw materials or if you also have the capability to coat our components. If coating services are available, please provide details on your process and any relevant specifications. We're looking to collaborate on this project, so any information you can share would be greatly appreciated. Thank you!
