In extrusion, raw materials are fed into the machine, heated, combined, and propelled through a die to produce a wide variety of parts such as PVC profiles, plastic sheets, granules, and etc.
Extruders were invented in early 19th century. A wide variety of models have been made ever since but none were practically used in plastic industry.
It wasn’t until different variations of plastics came to the market in early 20th century that the first successful plastic extrusion was performed.
Today, extruders are widely applied in many different areas like metal, food, and plastic industries. In plastic industries they’re used to manufacture plastic pipes, PVC profiles, and electric hoses at any length. One good part about extruders is the low amount of wastes. Production wastes or defective parts can be reused which will significantly reduce economic losses

Extruders

In rotational molding industry, if a manufacturer ever desires to produce multi-layered, colored tanks, and other parts with modified specifications he will need the help of an extruder. Along with the main material, additives including colors or materials are also fed into the machine resulting in a final product with modified specifications and/or with desired color.
Polyester, PET, and different types of Polyethylene (LDPE, HDPE, and etc.) can be used to produce parts with any desirable length. Due to the temperature of the product, it’s also possible to modify the final outcome to achieve the desired shape.

How the extruder works.

Raw materials are firstly fed into the machine through a hopper, dropped unto a rotating screw which moves the materials forward, melts them with the help of heaters, and finally propels them through a die to produce pipes, hoses, films, sheets, and structural parts.
