valve-less01

We accommodate micron-level clearances for valve-less piston pump components and air bearing components.

At Niimi Sangyo, we achieve high-precision ceramic structural components at low cost and with short lead times through our proprietary technology (in-house developed kiln) and integrated production system.

Features of High-Precision Clearance Parts

Surface Characteristics Suitable for Usage
Accommodates surface characteristics from Ra0.4 to Ra0.1 mirror finish, tailored to rotational and sliding speeds.
Excellent Wear Resistance
Superior wear resistance compared to metals, resulting in long service life.
Sub-Micron Processing Accuracy
Capable of processing with accuracy up to 0.1 µm (0.0001 mm).
Outstanding Chemical Resistance
Suitable for conveying acids, alkalis, organic solvents, and more. Resistant to corrosion, ensuring long durability.
Safe for use in medical applications as ceramics do not leach out.

We also assist with cost reduction!
