plastic molding methods injection vs extrusion in norway

  • The Difference Between Extrusion and Injection

    2020-2-12 · Plastic manufacturers primarily use two methods for plastic molding. In the first, plastic injection molding, manufacturers “inject” molten plastic resin into a mold and let it settle and cool into a specific shape. In the second, plastic extrusion, manufacturers push melted plastic through a die to create the desired shape. Each method has unique advantages […]

  • Plastic Extrusion vs. Injection Molding

    2016-3-18 · Both extrusion and injection molding have their own advantages. An advantage in using the extrusion process over other methods is its ability to create complex cross-sections. Additionally, both stiff or soft materials can be formed into any shape and the finished materials have a smooth surface finish when compared to other processes.

  • Plastic Molding Methods: Injection vs. Extrusion ...

    Extrusion molding involves forcing melted plastic through a die into a shape with a fixed cross section. It’s an efficient way to produce many shapes. Since the plastic is melted from a solid form and then resolidified, only thermoplastics can undergo extrusion. The extruded part is cooled and can be cut or rolled for shipment.
