This product page explains the quality inspection process for the SICOPRO LVLP spray gun. Each key stage is designed to confirm material quality, component fit, nozzle precision, trigger response, air seal performance, spray pattern stability and final packaging quality before shipment.
Incoming parts inspection checks raw materials and key components.
Cup and lid fit check confirms sealing and secure assembly.
Nozzle precision check verifies size, surface finish and machining accuracy.
Trigger function test confirms smooth movement and response.
Air leak and spray pattern test verifies airtight performance and stable output.
Final inspection and packaging confirm appearance, function and packing quality.
