Actual Throughput
When evaluating a capping machine, buyers should focus on the actual output of perfectly sealed shampoo bottles per shift, not just the nameplate speed. High-speed capping output is heavily influenced by bottle stability, cap feeding consistency, and line synchronization. Testing with your actual shampoo bottles and pump caps provides a realistic foundation for your capacity planning.
High-Speed Screwing Quality
At high speeds, torque accuracy alone is not enough. Buyers must also verify thread engagement, proper dip tube insertion, and nozzle orientation. The equipment should be tested under real production conditions to ensure it prevents cross-threading, avoids tube pinching, and keeps the pump head scratch-free. This guarantees an airtight seal and a flawless finish even under maximum operating speeds.
