Extruder screw barrel is one of the most critical components in a plastic extrusion machine. It is responsible for melting and mixing of raw materials and converting them into finished products of the desired shape and size. Extruder screw barrel generally consists of a hollow cylinder with a screw rotating inside it. It varies in size and design depending on the type of extrusion process and the raw material to be extruded. There are two major types of extruder screw barrel: single-screw extruder screw barrel and twin-screw extruder screw barrel.
Single-screw Extruder Screw Barrel
A single-screw extruder screw barrel is widely used in the plastic processing industry. It is simple and widely available in screw diameters ranging from 15 mm to 300 mm. The main advantage of a single-screw extruder is the low cost of production, which makes it popular in small and medium-sized businesses. It can process almost any type of plastic material, including thermoplastics, thermosets, and elastomers. The single-screw extruder requires less maintenance, which is another factor contributing to its popularity.
Twin-screw Extruder Screw Barrel
The twin-screw extruder screw barrel is more advanced and complex than the single-screw extruder. It comes in different designs such as co-rotating, counter-rotating, intermeshing, and non-intermeshing. The twin-screw extruder is used in large-scale production, requiring higher levels of precision and control. With a twin-screw extruder, the raw material is compressed and melted more efficiently, which results in higher production rates and better product quality.
Market Trend of Extruder Screw Barrel All Over the World
The global extruder screw barrel market is expected to grow at a CAGR of 3.2% during the forecast period (2021-2026). The major factor driving the growth of the market is the increasing demand for plastic products in various end-use industries such as packaging, automotive, construction, and healthcare. The growing use of plastic products has led to an increase in demand for extruder screw barrels, which are essential components in plastic extrusion machines.
