  • Discussion for hardness and abrasion principle of Omega301 Alloy As we all know, when some kinds of plastic are running inside an extruder and an injection machine, there is a friction between barrel and screw, and a cut force between plastic and machine parts. Also there is a case that these machine parts are...
  • What is the screw OD65 wear characteristic and counter measure? Base on the data information screw OD65, its L/D ratio reach 37.17, which is very rare seen. With this kind of L/D ratio, when the screw running, the screw flight outer diameter at the metering zone will create a heavy adhesive wear which is...
  • The information about our Omega 301 alloy Our Omega 301 alloy integrates high wear-resistance of Omega 101 alloy with high corrosion-resistance of Omega 201 due to average dispersedness of tungsten carbide grain in a hard and corrosion-resistant Ni-based alloy. As per this property, our...
  • Analysis of Abrasion Mechanism for an Extruder Cylinder & Screw 1. Generally say, how many abrasion categories of mechanical components could be divided into?  Generally say, abrasion of mechanical components could be mainly divided into four kinds in theory: Adhesive wear, Abrasion wear,...
  • What properties you need for your bimetallic barrel? To face any condition that you might encounter, you need good quality barrel and screw. They must not get corroded easily or get bend on striking lightly. It should be durable, have strength, and must be corrosion resistant. For screws it is...
  • How does plastic extrusion process with screw barrel Plastic extrusion is not only a complicated process, but also a fine and high volume manufacturing process. It has been widely used to produce many products such as pipes, tubes, sheets, wire, frames. A great advantage of extrusion is that pipes...
  • Choose alloy layer for Bimetallic Barrel and Bimetallic Screw We are afraid when an alloy layer to be chosen, the most important determinant is what about the contact wear ration between these two kinds of metal. General say, the same metal meet together, and even both through the same hardening way, this...
  • Damage reasons of bimetallic barrel and screw When material is rotated between barrel and screw, the friction will make the surface wear. The diameter of screw gets smaller while the diameter of barrel inner hole gets bigger. So that the gap between barrel and screw will gets bigger with...
  • Technical Specifications of Bimetallic Barrel In the cylinder inner wall, casting a 2-3mm alloy layer which is wear resistant, corrosion resistant and high temperature. The lifespan of bimetallic barrel and screw will be greatly improved than ordinary nitriding cylinder, especially for...
