Application
  1. The fat barrel, with an all-stainless steel compartment and insulation measures, ensures reliable performance, a reasonable structure, and stable quality. It increases production efficiency by 2-3 times compared to average machines, with a 25% reduction in energy consumption.
  2. The machine's feeding system includes a primary and secondary feeding device, ensuring a stable feed rate through adjustable transmission.
  3. EPS beads pass through the material, enter the fluidized bed dryer (optional), and are delivered via a fan to the aging silo, completing the raw foaming process. The cycle is based on second foaming.
  4. The machine produces more uniform foam density, ranging from 7-35 kg/m³.
  5. Users can choose to install steam valves according to their needs.

Tungsten Alloy Rods For Counterweight

Tungsten alloy rods are commonly used as counterweights in various applications due to their high density and excellent mechanical properties. These rods are made by combining tungsten with other metals such as nickel, iron, and copper to create a material with a high density and high strength.

The most common application for tungsten alloy rods as counterweights is in the aerospace industry. They are used to balance aircraft control surfaces, such as ailerons and elevators, to ensure stable flight. Tungsten alloy rods are also used in the automotive industry as counterweights for crankshafts and flywheels to reduce vibration and improve engine performance.

In addition to their use in aerospace and automotive applications, tungsten alloy rods are also used in the medical industry as radiation shielding and in sports equipment as golf club heads and fishing weights.
