Kneading elements for dispersive and distributive mixing. Machined in our own Henan workshop — to your drawing, or reverse-engineered from your worn parts.
Kneading blocks decide how hard you work the melt. Narrow discs with a steep stagger angle disperse fillers aggressively; wide discs with a shallow angle distribute without over-shearing. We machine both to your specification.
Hardened or wear-alloy edges depending on how abrasive your compound is.

Standard range shown. Every dimension below can be changed to your machine, resin and output — custom manufacturing is our daily business.
| Types | 30° / 60° / 90° stagger, custom |
|---|---|
| Disc width | To specification |
| Material | Wear-resistant tool steel / alloy |
| Edge treatment | Hardened or alloy-faced |
| Bore / spline | To your machine |
| Supply | Individual or configured sets |
| 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 |
30° distributes gently, 60° is general purpose, 90° disperses aggressively. Tell us the compound and we advise.
Depends on filler hardness and loading. On glass-filled compounds hardfaced edges last several times longer — we will give you a realistic figure for your material.
Yes, from a drawing or by measuring a sample set.
