What is a Extruder?

An extrusion molding machine is a machine that heats a material to soften it and extrudes it with a cylinder screw to continuously process it into a tube or rod. The mechanism is similar to the image of a udon molding machine or Tokoroten. An extruder is used to process pellet or minced material into round or square pipes, tubes, ducts, sheets, etc. Extrusion molding has been around for a long time, but it is widely used not only for food products but also for processing metals and plastics. After passing through an extruder, plastics, etc. are cooled by water or air and cured to make a final product or fired.

Application of Extruder

Extruders heat materials, melt them, and extrude them, so they are used to mold aluminum, copper, alloys, magnesium rods and tubes, wires, and plastics. Recently, ceramic bricks are also made by extrusion. Synthetic fibers made from plastic are extruded halfway through the raw material and then processed into fine threads. Outside the industrial sector, extruders are also used to process foods such as sausages, pasta, rice noodles and pet food.
