Tie every hose length to its compound batch, cure chart and proof test.

Hose making is a chain of separate stages. A mixer prepares compound, an extruder forms the inner tube, a braider or spiraller lays reinforcement, and an autoclave cures the lot on mandrels or in coils. Each stage keeps its own sheet. Nobody holds all of them. A burst failure in the field sends everyone looking through all of them.

Hose manufacturer software keeps those sheets under one job number. Cut lengths, crimped assemblies and bulk coils then trace back to the batch and the cure. The compound mixer, extruder, braider, autoclave and test bench sheets then sit as one chain under a single order.

A buyer sends a drawing or a part number: inside diameter, working pressure, fluid, bend radius and length tolerance. The planner checks which mandrel sizes are free, which braid or spiral wire is in stock, and whether the autoclave has room before the customer’s promised week runs out. Compound is called from the mixing room, tube is extruded, reinforcement goes on, and the cover follows. Wrapped lengths wait in line for the autoclave, and the cure cycle depends on wall thickness.

After cure, hoses are stripped from mandrels, cut to length, couplings are crimped and each assembly goes to the proof test bench. A sample of the lot is taken for burst testing, and the figure goes on a bench sheet that the quality engineer reviews before the lot is released to dispatch. Passed hoses get a tag. They are packed to the order and leave with a delivery note. Rejects are scrapped or cut back to shorter lengths for stock.
