| Extruder operator | Occupations | 1: Sets up and operates tuber machine to extrude rubber in specified form: Selects and installs die in machine, using handtools. Turns steam valve or lights gas burner to heat machine to desired temperature. Starts machine, turns dial for specified extrusion speed, and turns die screws to extrude stock of specified size. Feeds rubber stock into machine by hand or conveyor. Verifies dimensions of extruded rubber with gauge, calipers, and ruler. Turns wheels or pulls levers to synchronize conveyor with extruding speed. May be designated according to product extruded as Garden-Hose Tuber-Machine Operator (rubber goods); Inner-Tube Tuber-Machine Operator (rubber tire); Rim-Strip Tuber-Machine Operator (rubber tire); Rubber-Flap Tuber-Machine Operator (rubber tire); Solid-Tire Tuber-Machine Operator (rubber tire); Tread-Tuber-Machine Operator (rubber tire).

| 2: Sets up and operates machine to extrude thermoplastic materials to form tubes, rods, and film according to specifications: Installs dies, machine screws, and sizing rings, using handtools. Couples hose to die holder to circulate steam, water, air, or oil to die. Weighs and mixes pelletized, granular, or powdered thermoplastic materials and coloring pigments in tumbling machine according to formula. Fills machine hopper with mixed materials, using conveyor auger, or stuffs rolls of plastic dough into machine cylinders. Starts machine and sets controls to regulate vacuum, air pressure, sizing rings, and temperature; and synchronizes speed of extrusion with pulling rolls. Examines extruded product for defects, such as wrinkles, bubbles, and splits. Measures extruded articles for conformance to specifications, using micrometers, calipers, and gauges; and adjusts speed and weight controls or turns hot and cold water, air, oil, or steam valves to obtain product of specified dimensions. Tests physical properties of product with acid-bath tester, burst tester, and impact tester. May reel extruded product into rolls of specified length and weight [EXTRUDER-OPERATOR HELPER (plastic prod.; plastic-synth.)]. (references) | |||
| 3: Sets up and operates extrusion press to shape hot billets into products, such as bars, tubing, structural shapes, and rods: Installs dies, mandrels, containers, heating coils, press tools, extrusion heads, and run-out bridging in press, according to size and type of product, using handtools. Removes billet from furnace when color indicates specified temperature and guides it along extrusion press conveyor onto press bed, and into billet container, using tongs. Starts ram that spreads billet into container and forces it through press. Regulates rate of extrusion to prevent metal rupture and adherence of metal to container walls. Starts press run-out table and butt shears to guide extrusion from press, and to trim flash. Pulls extrusion along conveyor to racking table. Sprays die with lubricant and caustic, and oils blocks and mandrels. Records data, such as crew time, number of billets used, and items processed. May operate extrusion press equipped with furnace that ejects hot billets into press chamber for ram to force through die. May set up and operate extrusion press to shape hot, radioactive uranium fuel elements. (references) | |||
| 4: Operates dough-mixing-and-extruding press to produce cereal products in form of letters, pellets, or other shapes: Cleans and installs perforated metal disk, containing openings of various shapes, in mixer. Attaches blade, using wrench, that sweeps around disk, shearing off extruded dough as it is forced through holes. Moves controls to set temperature of water, start flow of flour, water, and other ingredients into mixer, and regulate pressure forcing dough through extrusion die to maintain specified moisture content, color, and consistency of dough. May operate extruding press only, when mixing is performed by another worker. May be designated by form of extruded product as Pellet Operator (grain-feed mills). (references) | |||
| 5: Tends one or more extruders that form particleboard from wood chips treated with glue: Turns nuts on machine to regulate platens according to thickness specified for boards, using wrenches. Selects ram that corresponds to platen setting and positions ram on machine spindle. Notifies CHIP-MIXING-MACHINE OPERATOR (wood prod., nec) to start flow of charge. Starts ram that forces charge through extruder, forming continuous sheet of particleboard. Alters space between platens as directed. May be designated according to type of extruder operated as Extruder Operator, Horizontal (wood prod., nec); Extruder Operator, Multiple (wood prod., nec); Extruder Operator, Vertical (wood prod., nec).

| EXTRUDER TENDER | Occupations | Tends machine that extrudes rubber compound to produce strands for use in making elastic yarn: Adjusts valves to regulate and maintain specified flow of rubber compound and size of extruded strand. Separates strands in acid bath with tweezers and places strands on rollers leading to curing oven. Cleans and replaces nozzles. Fills feed tank with liquid-rubber compound. (references) | |
| Extruder tip | Mechanical Engineering | The center member of an extrusion die that determines the internal shape and dimensions of a hollow product. Source: European Union. (references) | |
| Sample extruder | Mining | A mechanical device for removing a soil sample from a sampling tube; usually consists of a piston driven by a jackscrew or a hydraulic mechanism. (references) | |
| SYNTHETIC-FILAMENT EXTRUDER | Occupations | Tends machines and auxiliary equipment that extrude continuous synthetic filaments from liquid polymer: Starts metering pumps and observes operation of machines and equipment to ensure continuous flow of filaments extruded through spinnerettes and to detect processing defects, such as drips, filament stains or missing, oversized, or fused filaments. Notifies other workers through intercom when defects occur, necessitating interruption of extruding process, to clean spinnerettes. Opens cabinet doors to cut threadlines (multifilaments) away from guides, using scissors. Lowers pan inside cabinet to catch molten filaments until flow of polymer through $T3packs$T1 is stopped. Presses metering-pump buttons and turns valves to stop flow of polymer. Cuts entangled filaments wrapped around gears of machine, using pliers. Restarts metering pumps, notifies other worker to receive threadlines, pulls extruded filaments together below spinnerettes to form threadlines, and inserts threadlines through guides to facilitate drawing process on floor below. Observes flow of finish across finish rollers and turns valves to adjust flow to specifications. Occasionally removes polymer deposits from spinnerettes and equipment, using silicone spray, brass chisel, and bronze-wool pad. Wipes finish rollers with cloths and washes finish trays with water when necessary. Marks type of malfunctions on maintenance tag, and attaches tag to machine for subsequent repair. (references) | |
| Synthetic-staple extruder | Occupations | Tends machines that form continuous synthetic filaments from liquid polymer and lay tow in cans according to specified pattern: Installs $T3pack$T1 into machine, using handtools, and turns lever to activate metering pump which controls amount of polymer extruded through pack. Catches extruded filaments in compressed-air gun and threads filaments through guides to capstans. Separates filaments at spinnerette, by hand, inserts cooling tube into spinnerette, and pushes lever to force air through tube to cool filaments. Guides tow over capstans and into device that lays tow into cans according to specified pattern. Observes machine operation, panelboard, gauges, and rotameter to detect machine malfunction. Turns valves and levers to adjust machines as necessary. Cuts windup from capstan. Notifies Polymer Department, using telephone, when color of polymer is not according to specifications.
