Cut, mould or splice each rubber gasket from the right sheet, die and drawing.

A rubber gasket shop supplies the flat ring, the full-face gasket, the door seal and the sump gasket. Each sits between two parts. Its job is to keep a fluid or a gas where it belongs. Some are cut from sheets of nitrile, EPDM, neoprene or silicone with steel rule dies, a water jet or a knife cutter. Others are moulded or extruded and joined into loops. Each type needs its own record.

Software for gasket makers links the drawing revision to the material, the cutter and the sheet used. Estimators price by nesting yield, planners batch parts that share a sheet, and stores know which offcuts are still usable before anyone opens a fresh one. Buyers get the right part, in the right count, with the material name on the bag.

A buyer sends a sketch, a drawing or an old gasket as a pattern. The estimator reads the inside and outside diameter, the bolt hole circle, the thickness and the rubber grade, then checks which fluid or temperature the gasket meets. Every gasket starts as a measurement. The shop prepares a cutting file or a steel rule die, then cuts one trial piece and measures it against the drawing before committing a full sheet.

Sheets come from stock by grade, hardness and thickness, and the operator nests the parts to cut waste before cutting on a press, plotter-knife or water jet. Holes are punched, edges are cleaned and adhesive backing is applied where needed. Extruded profile is cut to length and joined by vulcanising or bonding into a loop. Parts are counted into bags and labelled with part number, material and count. Then the pack goes out.
