Brake Hose Lead Time: How 8 Million Meters a Year Works

A buyer planning a launch deserves capacity figures, not a promise. So here are ours: an annual output of 8,000,000 meters of hose and more than 5,000,000 sets of assembly, a 20,000 m² site with over 12,000 m² of building, a team past 80, and 130 sets of equipment — more than 100 braiding machines, 30 high-speed braiding machines, and testing equipment that meets SAE J1401. Say those numbers back before you plan against them. Two of them measure different things, and those two are why most lead time conversations start in the wrong place.

8,000,000 meters a year is an extrusion and braiding figure. 5,000,000 sets a year is an assembly figure — crimping, testing, packing. Different products, different queues. A bulk coil order and a finished assembly order with the same “1,000” in the quantity field are two different jobs with two different bottlenecks: the coil order fights for line time, the assembly order fights for crimping and test capacity. Divide the annual output by working days and you get an order of magnitude to sanity-check against, not a promise — it describes capacity, not your scheduled date. A supplier who quotes you one lead time for both has not yet told you which queue you are in.

The sequence is fixed: compound preparation, tube extrusion, reinforcement braiding, cover application, cure, cutting, fitting and crimping, testing, and packing. Some steps batch, some do not — extrusion and cure reward a full run, while finishing and testing run per-assembly. So the honest answer to “when will it ship” depends on whether your order can group with similar work, and on whether the specification was frozen before the run was scheduled. Change the fitting or the length after scheduling and you do not move a step — you move the whole queue behind you. Lead time is mostly a sequencing question, and sequencing is decided before production starts.

Send these with your enquiry and the date you get back becomes a schedule, not a guess. Inner diameter and the standard you are buying against. Fitting type, thread, and orientation. Cut length or assembled length, with the measurement basis stated. Packaging — bulk coil or finished assembly, and the labelling your market requires. And the volume split, because one 20,000-unit order is a different scheduling problem from four 5,000-unit releases. Then ask your supplier for a written lead time that names the queue, the batch size that triggers a re-run, and the point where a specification change resets the date. An RFQ carrying those five items is what turns a capacity figure into a calendar.

Score your planning against six targets. Lock the specification — drawing and fitting spec — before scheduling, not after. Have the queue named on the quote: bulk coil or finished assembly. Agree the release schedule in writing, each release dated, rather than one total. Know in writing the point after which a change resets the date. Build buffer for testing and packing into your own plan, matched to your market’s documentation needs. And make sure batch reports for the shipment land inside the same delivery window. Hit all six and you stop asking when it ships — you already told the factory, and the factory told you.
