Inquiry about Custom Internal Replacement Parts for Karl Storz/STEMA Bipolar Resectoscopes NEW

Hello, I am a biomedical equipment repair lab in Mexico, specializing in component-level service for rigid endoscopy and urology equipment. I am looking for a certified manufacturer to produce custom internal replacement parts for the white working element block of bipolar resectoscopes, specifically for Karl Storz and STEMA brands. The original manufacturers do not sell these internal sub-components, so I need a partner to manufacture the following parts: golden internal contacts and blue external insulators. Please confirm if you have the capability to manufacture these specific parts. Also, what is your minimum order quantity for a first sample order? I need to test mechanical tolerances and electrical continuity in my lab before placing a bulk order.
