Conveying, kneading and mixing elements for co-rotating twin-screw compounders. Machined in our own Henan workshop — to your drawing, or reverse-engineered from your worn parts.
Segmented elements let you rebuild a compounding screw section by section instead of replacing the whole thing. We machine conveying, kneading and mixing elements in wear-resistant alloys, to your bore size and spline.
Commonly supplied for co-rotating compounders; we can match an existing configuration from a drawing or a sample element.

Standard range shown. Every dimension below can be changed to your machine, resin and output — custom manufacturing is our daily business.
| Bore size | To your machine specification |
|---|---|
| Types | Conveying / kneading / mixing / rotor |
| Materials | Wear-resistant tool steels and alloys |
| Spline | Internal spline to drawing |
| Supply | Single elements or full configurations |
| Machining | To drawing or sample |
| 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 worn element and we measure and reproduce it. A drawing is better if you have one.
Tell us the filler and abrasiveness. Glass-filled and mineral-filled compounds need harder alloys than unfilled ones.
Yes — we can supply a complete assembled configuration or individual elements to rebuild part of one.
