Daily maintenance is a routine task that does not interfere with equipment operation time and is usually performed concurrently with machine operation.

Typically 100-600 rpm, affecting output and melt quality. Higher speeds can increase output but may lead to material degradation.

A screw extruder is a mechanical device that uses a rotating screw to propel materials forward, achieving plasticization, mixing, and extrusion molding.

A single screw consists of a helical main shaft, divided into a feeding section, a compression section, and a homogenization section.

To fully utilize the performance of bimetallic screws and extend their service life, proper selection and maintenance are crucial:

Compared to traditional screws, bimetallic screws offer several advantages:

A bimetallic screw is not simply a combination of two metals, but rather a screw formed by bonding two metals with different properties at the molecular level through a special man

A twin-screw extruder consists of two rotating screws arranged in parallel with the same helix angle.

Screw specifications are typically classified based on key parameters such as diameter, pitch, length, material, and application.

The most common methods for securing a screw to a steel frame are using nuts, welding, or expansion bolts.

Do not start the machine before the screw reaches the pre-set temperature.

Common screw materials in my country include 45 steel, 40Cr, nitrided steel, 38CrMoAl, and high-temperature alloys.
