- 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
- What Makes for Perfect Control in Tubing Extrusion?
Extrusion is nothing without in-process measurements But what you do with those measurements can mean everything to transforming yields and profitability
- 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
- Exelliq Stacking System Automates Profile Extrusion
Pipe, Profile Tubing Extrusion Novel Profile Cooling Technology Promises Big Output Boost The iQ STACK from Exelliq is designed to enable fully automated profile handling For example, when unloading a full rack to feed profiles into a lamination unit, iQ STACK separates, aligns and reliably transports the parts
- PET Processing - Extrusion | Plastics Technology
In extrusion, most PET is processed into sheet for food packaging applications The PET sheet or PET film is thermoformed into products such as drinking cups, trays, clam shell containers and the like
- Stop Die Buildup | Plastics Technology
Stop Die Buildup Die buildup, also called die drool, die bleed, or plate-out, can plague any extrusion process
