Feed screw for molding machine are commonly used in the plastics and food production industries to move, mix and extrude product.

In the plastics industry, feed screws are the hearts of the extruders used in blow molding, injection molding, sheet extrusion and profile extrusion.

In the food industry, feed screws are used essentially the same as in the plastics industry. The primary difference is that instead of melting the material, the food is cooked as it passes along the feed screw and formed into the desired shape at the end. Instead of applying direct heat, some types of food processing equipment use the feed screw to build up pressure, which generates the heat needed to cook the food product.

Feed screws are not only useful to extrude products. They are also used frequently in many industries to mix various raw materials into a final product.
