Modular twin-screw barrel segments with vent, side-feeder and closed configurations. Machined in our own Henan workshop — to your drawing, or reverse-engineered from your worn parts.
The modular barrel is the layout freedom of a twin-screw line: vent where the moisture is, side-feed where the filler goes, closed where the heat builds. We supply individual segments — vented, side-feed, closed and blast-port — bored and lined to match your existing shafts and tie rods.
Built for parallel co-rotating lines of all common scales. Send your barrel layout drawing or one worn segment and we reproduce the set, including bimetallic linings for filled duty.

Standard range shown. Every dimension below can be changed to your machine, resin and output — custom manufacturing is our daily business.
| Bore | Ø20–135 mm typical |
|---|---|
| Types | Closed, vented, side-feed, blast-port |
| Lining | Nitrided or bimetallic 2–5 mm |
| Cooling | Jacketed, to match your thermal layout |
| Material | 45# steel body / alloy options |
| Lead time | 25–40 days |
The honest answer depends on your resin, not on price. Here is how we advise customers.
| Gas Nitrided (38CrMoAlA) | Bimetallic Alloy Lining | |
|---|---|---|
| Best for | Unfilled PE, PP, PS, ABS, virgin PVC | Glass-filled, mineral-filled, recycled, corrosive |
| Surface hardness | HV 900–1020, depth 0.45–0.7 mm | Alloy layer 2–5 mm, metallurgically bonded |
| Typical service life | Baseline | 3–5× baseline on abrasive resin |
| Cost | Lower | Higher, recovered through fewer stoppages |
| Certification | MTC with heat number | MTC + hardness records, third-party on request |
Yes — send one segment or the layout drawing; we match bore, centre distance, dowels and cooling jacket.
Yes — common for glass-filled and mineral-loaded duty; the lining goes where the wear is.
Both — individual replacement segments and complete re-lined sets.
