Technical Support

In the following sections you will be able to read about what makes our different alloys so special. They have all been carefully formulated by our team of experts for maximum performance to satisfy the production demands of our customers.

  • Iron-base Ω101 Alloy and Its Characteristics Alloy Ω101 is a special type of metal with a lower melting point yet it offers high hardness and wear resistance. These features make the material suitable for use as an alloy layer on the surface of a barrel bore, extending the service life of the extruder or injection molding machine in which it is installed.
  • Technical Information of Ω301 Alloy In recent years, more and more reinforcing agents and fillers have been added to ordinary polymer materials. As a result, the core components of extruders and injection molding machines, such as screws and barrels have experienced a greater amount of wear and corrosion.
  • Information of Fe-base Ω101A Alloy High chromium cast iron Ω101A developed by Shanghai Omega is mainly applied in the liners of extruder barrels. Its corresponding material number to the Company of Werner & Pfleiderer GMBH in Germany is 1.2292.2, which is also known as 043.
  • Information of Fe-base Ω102A Alloy Ten years ago, our company has researched and developed high-chromium iron Ω101A, which is similar to Germany No.043 and really has boomed in plastic modification market, it almost has become a standard configuration product for the twin screw extruder barrel in China these tears.
  • Information of Co-base Ω301A Alloy Since Elwood Haynes from America designed Co-based Carbide Alloy in the beginning of the last century, its high temperature-resistant, corrosive-resistant and cavitation-resistant features of Co-Cr-W-C alloy have become famous all over the world.
  • Information of C/SiC Composite With the increasing demand for abrasion-resistence and corrosion-resistence of core parts of extruder, bimetal barrel and screw is not enough for all the circumstances. To process materials with special physical or chemical properties, we researched and developed SiC composite ceramic liners and barrels to be the substitutes of currently widely used bimetal screws and barrels.
  • At what time we have to use the liner technology The length of the cylinder is more than the length of the furnace and centrifugal machine. The furnace and centrifugal machine have its own certain length, all of the barrel manufacturers worldwide are subject to this limitation...
  • Material and Technology Information Of PM-HIP Oval liner The typical material model of our PM-HIP Oval liner is equal to model 1.2292.2 from W&P in Germany. The material name is G-X 250CrV25, or GP 27M at W&P company. The name of our product is Ω101A. The hardness of finished Ω101A ovalliner is HRC 60~64. Besides, there are two other kinds of alloy that need to be chosen.
  • Material Choices for Oval liner and Screw Element For high-wear resistant screw elements, the material is usually processed with HSS (high speed steel), Chinese name is W6Mo5Cr4V2, American name is AISI: M2. HSS is one kind of alloy tool steel. Its main component is W, Mo,Cr, V, Si, Mn, all the alloy element is up to around 10~25%...
  • Information of Nanometer Ceramics Compound Coating for Single Screw and Screw Element & Kneading Disk Nanometer Ceramics Compound Coating is one kind of new and High-tech surface treatment technique for metal material, which will be used for many fields. The machinery parts perform a super-hard micro hardness, high wear-resistant and corrosive-resistant features by adding Nanometer Ceramics Coating on the surface.
Extrusion professional
We have several advantages over our competitors:
  • Strong designing strength
    We design and manufacture the screws, barrels, and extruders according to customer requirements.
  • Extensive experience
    We have been in the extrusion industry for decades, and our products are used by prominent companies such as Foxconn.
  • Advanced material technologies
    Our PM-HIP processing technology increases the material density and reduces casting defects. The new design of an aluminum alloy clad layer on SiC ceramic allows the extruder to work, even in harsh conditions.
