Cemented carbide offers excellent corrosion, high-temperature and wear resistance.
It is used for wear-resistant parts of extruder equipment.
It is used for kneading and extruding materials such as food and feed, resins, reinforced plastics and lithium-battery slurry.

Carbide Wear Components for Extruder Screws
Extruder screws and barrels operate in a highly abrasive environment where steel components wear out quickly. Yatech tungsten carbide extruder parts dramatically extend service life for extrusion equipment processing both plastics and alloys, including large-diameter screws.
- Screw flight protection: carbide flights and hardfacing elements sized to your screw geometry
- Wear pads and liners: replaceable carbide components for the highest-wear zones
- Custom production: manufactured to drawing with matched shrink-fit tolerances
By combining high hardness with good toughness, our extruder carbide resists both abrasive wear and the impact loads of continuous operation. Contact our engineers with your screw drawing for a material and cost proposal.

Frequently Asked Questions
Which extruder parts can you make from carbide?
Screw elements, wear rings, barrel liners, kneading blocks and other wear components for plastic, rubber and alloy extruders.
How much longer does carbide last vs tool steel?
In abrasive extrusion service, carbide wear components typically last 3–10 times longer than hardened steel, greatly reducing downtime.
Can you match my existing screw geometry?
Yes. We work from your drawings or from measured samples of the worn parts.
What is the MOQ and can I order samples first?
There is no fixed MOQ for standard items. Sample orders are welcome so you can verify quality before volume production; shipping is freight collect.
Which grades are available?
We offer wear-resistant WC-Co grades selected for your polymer abrasiveness and temperature. Our engineers will recommend the optimal grade.
