| High Light | Wear-Resistant Dosing Cylinder ，High Hardness Metering Cylinder ，Precision Machining Dosing Plunger | ||
High-performance tungsten carbide dosing cylinders and plungers for precision adhesive dispensing, potting, and fluid metering applications. Featuring HRA 89-92 hardness, exceptional wear resistance against abrasive fillers, and micron-level precision for consistent shot-to-shot accuracy.
In automated fluid dispensing, potting, and adhesive coating systems, metering cylinders (often called dosing cylinders or plunger dispensing pumps) are critical components that determine accuracy, consistency, and reliability. Premature wear due to abrasive fillers or high-viscosity media can lead to inconsistent injection volumes, leaks, downtime, and component failure.
Our tungsten carbide metering cylinders and plungers are meticulously designed as durable and precise core components for your dispensing operations. Manufactured using powder metallurgy and precision grinding processes, these components provide the extremely high hardness, superior wear resistance, and micron-level accuracy required for automated dispensing applications.
Tungsten carbide (WC-Co) is a composite material produced by powder metallurgy—mixing tungsten carbide powder with a metallic binder (typically cobalt) and sintering at high temperatures. For dosing applications, this material offers distinct advantages:
| Property | Tungsten Carbide Dosing Component | Stainless Steel Component | Benefit |
|---|---|---|---|
| Hardness | HRA 89-92 | HRC 40-50 | Superior wear resistance against abrasive fillers |
| Wear Resistance | 10-30× steel | Baseline | Dramatically extended service life |
| Corrosion Resistance | Excellent (chemically inert) | Moderate (susceptible to certain chemicals) | Compatible with aggressive fluids |
| Parameter | Options |
|---|---|
| Grade Selection | YG6, YG6X, YG8, YG15, or custom grades |
| Component Type | Dosing cylinder, plunger, matched set |
| Geometry | Standard cylindrical, stepped, tapered, with seal grooves, custom profiles |
| Surface Finish | Ground, polished, mirror-polished |
| Features | Flush ports, mounting features, seal grooves |
A dosing cylinder (also called a metering cylinder or dose cylinder) is a precision-bored component that, together with a plunger, forms a volumetric dispensing system. The plunger displaces a precise volume of material with each stroke, enabling accurate, repeatable dispensing of adhesives, sealants, potting compounds, and other fluids.
Tungsten carbide dosing components are compatible with a wide range of fluids, including epoxies, silicones, polyurethanes, UV-curable adhesives, thermally conductive pastes, silver-filled materials, and chemically aggressive fluids.
Service life depends on the specific application and material being dispensed. In abrasive-filled material applications, tungsten carbide components typically last 10-30× longer than stainless steel alternatives.
