How a Trumpet is Made
Final assembly and coating
A craftsman assembles the instrument by diligently soldering together the various components, such as the bell and the valve casings.
The surface of the instrument's body is polished to a shine with an abrasive-coated buffing cloth.
3. Electrostatic coating
Electrostatically-charged particles are sprayed onto the trumpet to form a resilient, uniform coating.
4. Adjustment and test-playing
Before shipping, each individual trumpet undergoes a rigorous functional inspection (which includes testing with an air leak tester and a strobe checker as well as pitch adjustment) and is test-played.
