- Plastics Extrusion | Plastics Technology
Extrusion is a continuous process through which parts of a fixed cross-sectional profile are made Material is fed through a hopper into an extruder, essentially a rotating screw surrounded by a heated barrel, where it is mixed, melted and pumped through a die The die gives the part its shape Types include film extrusion, sheet extrusion, pipe, profile and tubing extrusion
- Pipe, Profile and Tubing Extrusion | Plastics Technology
Pipe is formed when plastics is extruded through a round shaping die, cooled in a water bath, and either cut and coiled Used in manufacture of medical tubing; PVC pipe; HDPE pipe; siding; plastic decking; plastic fencing; window lineals
- Film Extrusion | Plastics Technology
Film extrusion is divided into two subcategories: cast film (flat film) and blown film In cast film extrusion, hot plastic is extruded through a flat, slit die onto a polished chill roll where it is quenched, pulled to a second set of rolls to cool the other side, then wound In blown film extrusion, plastic is extruded into a cylindrical die, then inflated to form a bubble, which is cooled
- Extrusion Conference 2025 Event Details | Plastics Technology
Extrusion#39;s general sessions cover best practices, troubleshooting and processing solutions that can help you run your operation and maximize the utilization of your existing assetsmdash;as efficiently as possible Extrusion professionals from the shop floor to the front office are represented at the Extrusion Conference Yoursquo;ll meet the entire global supply chain: manufacturing
- Sheet Extrusion | Plastics Technology
Sheet extrusion includes manufacture of industrial plastic sheet; packaging sheet; thin-gauge sheet; thick-gauge sheet; thermoformed sheet
- Sheet Extrusion | Plastics Technology
Sheet Extrusion Technology is designed to be used in conjunction with our 9-lesson single screw extrusion course It provides an overview of sheet extrusion technology ranging from parts and operation, to controlling plastic flow in the die, to troubleshooting the sheet extrusion line
- Extrusion: Start Up and Shut Down Properly | Plastics Technology
Extrusion: Start Up and Shut Down Properly A key goal during startup and shutdown of the extruder is to prevent degradation of the polymer left in the extruder and downstream components such as screen changers, adapters, and dies
- Stop Die Buildup | Plastics Technology
Stop Die Buildup Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process
