A Midwest air bag inflator company wanted to reduce costs by bringing in-house their tube cut-to-length and finishing operation. Haven worked with them from processing line conceptual layout and process design to plant installation and start-up!
Key Takeaways: An Integrated Processing Line from Haven
- Haven engineered a fully integrated tube‑processing line for an air bag inflator manufacturer, handling everything from concept and layout to installation and start‑up.
- The system combined unloading, polishing, cutoff, end finishing, inspection, and washing into a continuous, automated workflow with coordinated material handling.
- The line featured Haven’s Model 620 Kleencut supported shear cutoff and Model 939 double‑end finisher to meet high‑strength tubing and tight‑tolerance requirements.
Haven coordinated all communications related to process requirements, machine specifications, safety specifications, and especially, quality assurance. The resultant integrated processing line included: Bundle Unloader – with part separation and pusher assembly that advanced the tube into an O.D. polishing unit; Polisher – removed the black oxide coating on the tube; Exit Conveyor – transferred the polished tube to the cutoff section; Cutoff Loading System – accumulated tubes from the polisher and indexed them into the cutoff machine; Model 620 Kleencut supported shear cutoff – ideal solution for cutting high yield strength air bag tubing with no material lose from the cut; Double End Finishing – Model #939 end finisher with I.D. and O.D. chamfer and end facing to a tight tolerance and capability spec; 100% Length Inspection – check every tube to a pre-programmed tolerance range; Transfer to Parts Washer – automatic indexing and transfer onto washer belt spindles. All of these operations were tied together with various material handling systems for continuous product flow.
