Extrusion is a manufacturing process to make various plastic products of uniform cross-section of continuous length. In the extrusion process, plastic granules are fed to a hopper which is placed above a barrel. The barrel contains a feed screw and a die is attached at the end of the barrel. When the plastic granules come to the barrel they melt and a feed screw forces the liquid plastic through a die, forming a long tube like shape. The shape of the tube is determined by the shape of the die. The liquid plastic is cooled and it solidifies into a long tube which is cut at regular intervals. Various shapes result from the extrusion process such as plastic rods and strips. A feed screw barrel is a major component of an extrusion process.
Like extrusion, injection molding is also a manufacturing process to make molded plastic products. Similar to extrusion, in injection molding, plastic granules are fed to a hopper which is placed over a barrel. The barrel contains a feed screw. Molten liquid plastic is moved by the feed screw at the end of the barrel into a mold assembly. The mold assembly outputs the final molded plastic product. Like in extrusion, the barrel containing the feed screw is also a major component of the injection molding process.
Across the world, rising adoption of extrusion and injection molding in the global plastic industry is increasing the number of extruded and injection molded plastic products, which are subsequently increasing the demand for feed screw barrels.
Due to increasing usage of plastic products across the world, recycling of plastics is an important issue not only in developed countries but also in developing and emerging countries. This is a major restraint to the growth of the extrusion or injection molding manufacturing process which is subsequently affecting the growth of the feed screw barrel market.

The global feed screw market is segmented by type into extrusion feed screws and injection molding feed screws. By material, the global market is segmented into alloy steel, stainless, and specialty materials. By end-use industry, the market is segmented into chemical industry, food industry, and others.
By geography, the feed screw barrel market is segmented into North America, Europe, Asia Pacific, Middle East & Africa, and South America. North America is a prominent feed screw barrel market. The U.S. is anticipated to be the largest feed screw barrel market in North America followed by Canada. Europe is also a significant feed screw barrel market. Germany is expected to be the largest feed screw barrel market in Europe. The U.K., France, Spain, and Italy are other prominent feed screw barrel markets in Europe. Asia Pacific is expected to a major feed screw barrel market. China is anticipated to be the largest market in the region. India, Japan, and South Korea are other prominent markets in the region. There is a rising adoption of affordable, light weight plastic products across Asia Pacific including major plastic producing countries such as China and India. Rising adoption of extrusion and injection molded plastic products in China and India are subsequently increasing the demand for feed screw barrels across the Asia Pacific region. Middle East & Africa is another prominent market. GCC (Gulf Cooperation Council) countries are expected to constitute the largest market in the region. In the Africa region, South Africa is a major feed screw barrel market. South America is another significant feed screw barrel market, with Brazil the largest feed screw barrel market in the region followed by Argentina.
