What is bimetallic screw and barrel?
A
bimetallic screw and barrel is a type of screw and barrel combination used in plastic extrusion machines. The screw and barrel are made of two different metals that have different thermal expansion coefficients, which allows the screw and barrel to expand and contract differently as they heat up and cool down during the extrusion process.
The bimetallic design provides several benefits, including:
1.Increased durability: The bimetallic construction can withstand the high wear and tear of the extrusion process, leading to a longer lifespan and reduced maintenance costs.
2.Improved resistance to corrosion: The combination of different metals can provide improved resistance to corrosion, reducing the risk of damage from exposure to harsh materials and chemicals.
3.Improved temperature control: The differential expansion of the two metals allows for more precise temperature control, leading to more consistent processing and better product quality.
4.Increased process efficiency: The improved temperature control and reduced wear and tear can result in increased process efficiency and improved output from the extrusion machine.
