- How to make a Longer Bimetallic Twin Barrel Q: I was under the impression that the 2C halves are made from the Omega 301 alloy using the PM-HIP technology? A. No, this 301 alloy layer is only got by a normal bimetallic technology way, like all the bimetallic barrel, this time is...
- 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...
