Webbför 2 dagar sedan · Image credit: The Rodon Group. Injection molding can use thermosets or thermoplastics. A machine heats and mixes the plastic until it is in a pliable molten shape, then a screw device turns to force the plastic into an outlet that leads to the mold. Once the plastic sets, the mold opens to eject the product. WebbPlastics extrusion is a continuous high-volume manufacturing process, in which raw plastic is melted and formed into a continuous profile. This process starts by feeding plastic material (pellets, granules, flakes or powders) from a hopper into the barrel of the extruder. The material is gradually melted.
