Custom flanged barrel for extrusion and injection machines. Machined in our own Henan workshop — to your drawing, or reverse-engineered from your worn parts.
Flanges carry the load and the ports decide what you can inject or vent. We machine both to your drawing, then line the bore with alloy and hone it to size.
For extrusion and injection machines where the standard port layout does not fit your process.

Standard range shown. Every dimension below can be changed to your machine, resin and output — custom manufacturing is our daily business.
| Bore diameter | Ø20–300 mm |
|---|---|
| Alloy lining | 2–5 mm centrifugal |
| Flange | Multi-port, machined to drawing |
| Ports | Feed / vent / injection, to layout |
| Bore finish | Honed |
| Inspection | Dimensional + hardness records |
| Lead time | 35–50 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 — that is our normal way of working. Send the drawing or the old barrel and we work from that.
To your layout. Send the drawing and we confirm what is machinable before quoting.
No — drawing confirmation is part of the order. We only ask for the information we need to make it right.
