High Precision Smooth Twin Screw Barrel, Wear Stable Extruder Barrel for Plastic Compounding

Our high polish precision twin screw barrel matches all co-rotating twin screw extruders. We focus on smooth inner finish and tight dimensional tolerance. The barrel delivers stable extrusion performance for daily plastic compounding, masterbatch granulation and polymer modification. We use imported HIP powder high-speed steel as core raw material, the performance reaches top foreign OEM brand standards.

1. Strict raw material screening

   We source steel from top domestic factories and European extrusion material suppliers. Every batch gets elemental test and metallographic inspection. We cut off unqualified raw material before production.

2. Advanced HIP powder steel processing

   We apply imported HIP technology to process powder high-speed steel. This craft upgrades the barrel’s anti-corrosion and wear ability. The precision level fully equals original overseas first-line brand barrels.

3. Full CNC precision machining

   All barrel parts go through multi-axis CNC machining. We lock every size tolerance strictly. The finished shape fully fits your extruder screw assembly, no material leakage during running.

4. High gloss inner polishing treatment

   We finely polish the barrel’s 8-shaped twin inner cavity. Smooth surface avoids plastic sticking and carbon accumulation. You spend less time cleaning between formula switches.

5. Professional one-stop custom technical service

   Our technical team measures and reverses drawings from your old samples quickly. We also offer matching combination plans for barrels, screw elements and kneading blocks. We solve your matching problems in one step.

6. Stable wear resistance & long service life

   Fine selected raw materials plus HIP craft make the barrel hard to wear. The whole unit keeps consistent performance under long-time high-temperature extrusion work.

• Color masterbatch & filler masterbatch production
• Plastic recycling granulation
• Polymer reinforcement & flame retardant modification
• Degradable plastic extrusion
• Medium corrosive plastic compound production

We coat anti-rust oil on each barrel before packing. We use shockproof wooden export cases for sea and air delivery. Normal operation brings 12-month warranty. We supply CAD drawings and on-machine operation guidance for all clients.
