Keep every cylinder build, seal kit and leak test on record per order.

A cylinder looks simple until a customer orders it with a particular bore, stroke, rod end, cushioning and mounting style, such as a clevis or a foot bracket. Thousands of combinations come from a few dozen machined parts. The order has to say exactly which build it wants.

Order and production tracking for pneumatic makers starts from that configuration. It carries the drawing revision, the seal kit, the test result and the serial number from the sales order to the packed carton, so nothing is retyped. Send a sample order sheet and the build options become the first screen.

Distributors and machine builders send orders that name a series, bore, stroke and mounting, for example a 63 mm ISO 15552 profile with a rod lock. Planning reads each line against the drawings on file. One extra option code can change the barrel length, the rod diameter and the seal set at once. Planning then checks barrel tube, piston rod and end cap stock and releases a batch to the cells. Tubes are cut and honed. Rods are turned, induction hardened and chrome ground. End caps are milled and drilled for ports. Valve bodies are machined from aluminium bar or die cast blanks. Seals, wear rings and magnets arrive from outside suppliers in kits.

Assembly builds each cylinder to its configuration, greases the piston seal and fits the cushioning screws. Every unit goes to a bench for a leak check at working pressure. Some get a proof test or a life cycle run. Passed units are marked, boxed and packed against the distributor’s order. A complaint months later needs the serial number, so the team can find which seal lot and which bench result went with it.
