How do you control the inner and outer diameters of the hoses?

Question

Accepted Answer

Controlling hose inner and outer diameters (ID/OD) requires a highly systematic approach to guarantee compliance with strict tolerances. At PassionHose, we enforce a four-stage dimensional control protocol:

Tooling Selection: Engineers utilize precision-matched extrusion dies tailored to your specific ID/OD requirements.
Setup Validation: During initial extrusion, we use calibrated laser micrometers to map dimensions, making real-time adjustments until parameters stabilize.
In-Process Monitoring: Continuous inline measurement systems track the hose dimensions during production, instantly detecting and flagging deviations outside acceptable tolerances.
Final Inspection: Post-production, our QC team performs statistical sampling using digital calipers and Go/No-Go gauges.

Operating under ISO 9001 standards, all dimensional data is digitally recorded for full traceability. We can promptly retrieve historical production records to validate consistency for any specification.
