Custom Zirconia Ceramic (ZrO2) Components
Known as “Ceramic Steel” for its exceptional fracture toughness, high mechanical strength, and superior wear resistance. Perfect for high-impact and heavy-loading industrial applications. Tailored and tight tolerance CNC machining (±0.002mm) to your drawing.
High-Toughness Zirconia (ZrO2) Tailored for Severe Loading
Unlike conventional brittle technical ceramics, Zirconia exhibits a unique "transformation toughening" mechanism that halts crack propagation. This grants it mechanical properties that bridge the gap between ceramics and steel. Below are the two most critical industrial grades based on the environmental stresses
Y-TZP (Yttria-Stabilized Tetragonal Zirconia Polycrystal)
The Precision Standard. Features the highest mechanical strength and fracture toughness at room temperature. Exceptional wear resistance and mirror-like surface finish capabilities. Ideal for shafts, valves, plungers, and micro-machined parts.
Mg-PSZ (Magnesia-Partially Stabilized Zirconia)
The Thermal & Corrosion Champion. Offers superior resistance to thermal shock, high-temperature degradation, and chemical corrosion. It maintains its toughness in aggressive acidic/alkaline environments and harsh thermal cycling.

Precision Machining Capabilities for Zirconia Components
Due to its metal-like mechanical properties, Zirconia can be machined into highly complex geometries with ultra-fine surface features. We utilize diamond grinding, honing, and mirror polishing to meet strict OEM specifications.
Ceramic Pump Pistons & Plungers: Mirror-polished plungers and shafts for high-pressure dosing pumps and high-viscosity fluid handling, ensuring zero wear debris.
Industrial Blades & Slitting Knives: Ultra-sharp zirconia cutting tools, blades, and scrapers that retain their edge up to 100 times longer than steel.
Seal Rings, Bushings & Bearings: High-load bearing liners, structural subsea sleeves, and non-magnetic mechanical seal faces.
Custom Threaded & Micro-machined Parts: Intricate structural components featuring precision internal/external threads, complex multi-axis slots, and micro-holes.
Engineered for High-Wear & High-Impact Environments
The Challenge: Conventional steel pistons and alumina ceramic valves suffer from abrasive slurry wear and corrosive chemical erosion, leading to frequent maintenance and contamination.
Solution: Y-TZP Zirconia Plungers with mirror polishing (Ra < 0.05μm). The low friction coefficient and zero chemical reactivity drastically extend pump lifespan and ensure chemical purity.
The Challenge: Heavy mechanical impacts and friction welding during wire drawing or metal extrusion destroy standard tool steel and shatter fragile ceramics.
Solution: Mg-PSZ Zirconia Extrusion Dies and Guide Rollers. Its high fracture toughness allows it to withstand extreme mechanical impacts, while its thermal expansion matches steel, enabling seamless metal-to-ceramic assemblies.
The Challenge: Bio-inertness requirements, absolute zero metal ion contamination, and high mechanical stability during precise analytical dosing.
Solution: Medical-grade High-Purity Y-TZP Valves and Micro-fluidic Components, ensuring high precision and absolute biocompatibility under chemical sterilization.
Quality Controls from Drawing to Delivery
Ultra-Fine Surface Inspection: For parts requiring low friction, we guarantee and test surface roughness up to Ra 0.02μm using specialized profilometers.
Drawing Optimization: We don’t just quote. Our engineering team analyzes your drawings to propose minor geometric adjustments that prevent stress concentration and lower machining costs.
Low MOQ to Scale Production: We support small-volume custom orders for your R&D prototyping and verification phases, backed by scalable high-volume production capacities.
