Extrusion Technology for the Creation of
Advanced Ceramics

Shape Capabilities

Microporous Ceramics

High aspect ratio holes perforate a molded article in the extrusion direction. Typically, with fine holes (pores) of less than 1mm in diameter, it is difficult to achieve an aspect ratio (depth/inside diameter) of more than 5–10 using only machining. Extrusion molding technology, however, makes it possible to manufacture articles having micropore aspect ratios of 200 or more. Even articles with various thin or thick wall characteristics can be achieved.

Uses:
• Flow rate controllers
• Sensor holders
• Insulators (e.g., glass)

Non-Uniform Porous Ceramics

Porous ceramics can also be produced using micro-extrusion molding. Porosity of up to 70% can be set arbitrarily.

Uses:
• Filters
• Liquid holders
• Adsorption parts

Specialty Shaped Ceramics

Progress in Pilot IS Advanced Ceramic technology has made it possible to combine an abundance of different external and internal shapes, which can be utilized in new applications. For example, articles having a rectangular external shape and a circular internal shape, or a gear-like external shape and a circular internal shape are possible.

Uniform Porous Ceramics

Pilot IS can produce porous ceramics where even hard-to-stabilize flow rates are achieved by through-holes formed in the extrusion direction. Tiny, high-precision and uniform holes are applied to achieve gas and liquid flow rate control. Unlike a typical porous body, extrusion-molded holes pass through the molded article linearly, enabling a uniform, stable flow rate, while minimizing pressure loss.

Uses:
• Semiconductor manufacturing equipment
- Filters
- Nozzles
- Baffle plates
- Flow rate controllers
- Microreactors

Secondary Processing

The production of articles with unique, disparate external and internal shapes for specialized needs. Pilot IS Advanced Ceramics can be subjected to high-precision submicron processing for Outside-diameter machining, Pore machining for pore sizes of Φ 40 μm or more and Enhanced surface finishing.

Uses:
• Electrode guide for electric discharge machines
• Sliding shaft components
• Rotating shaft motor components
• Ferrules for fiber-optic communications and device components
• Positioning pins
• Liquid chemical plungers
