Chief Engineer Office
Shanghai Omega Machinery Co., Ltd.

We have several advantages over our competitors:

• Strong designing strength
  We design and manufacture the screws, barrels, and extruders according to customer requirements.
• Rich 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.
