Industrial sapphire lift pin's properties 

Industrial sapphire lift pins possess several key properties that make them suitable for high-precision and demanding applications. Here are the main properties of industrial sapphire lift pins:

High Hardness:

Mohs Hardness: 9, making sapphire the second hardest material after diamond. This property ensures exceptional resistance to wear and abrasion, prolonging the service life of the lift pin.

Excellent Corrosion Resistance:

Sapphire is highly resistant to most acids, bases, and other corrosive substances. This makes sapphire lift pins ideal for use in chemically aggressive environments.

Thermal Stability:

High Melting Point: Sapphire has a melting point of over 2000°C (3632°F), allowing it to maintain structural integrity at high temperatures.

Low Thermal Expansion: Sapphire has a low coefficient of thermal expansion, which means it experiences minimal dimensional changes with temperature fluctuations, ensuring precise performance.

Mechanical Strength:

Sapphire lift pins are strong and rigid, capable of withstanding significant mechanical stresses without deforming or breaking.

Dimensional Precision:

High dimensional accuracy and tight tolerances are achievable with sapphire lift pins, which is critical for applications requiring precise alignment and operation.

Optical Transparency:

Sapphire is optically clear in the visible and infrared spectra, which is advantageous for applications where optical properties are important.

Electrical Insulation:

Sapphire is an excellent electrical insulator, making it suitable for use in electronic and electrical applications where electrical conductivity must be minimized.

Biocompatibility:

Sapphire is chemically inert and biocompatible, which makes it suitable for use in medical devices and applications where interaction with biological systems is involved.

Surface Hardness:

The surface of sapphire lift pins is extremely hard and resistant to scratching and gouging, contributing to their durability and maintaining their functionality over time.

 Sapphire lift pins in ZMSH

Sapphire lift pins and guide/alignment pins offer exceptional mechanical strength and precision, providing stable dimensional control in high-temperature and chemically aggressive plasma environments over extended periods. Compared to quartz versions, sapphire pins exhibit a sixfold increase in strength and demonstrate no erosion over time, maintaining dimensional stability with precision and reproducibility within 0.0002 inches (5 microns). Sapphire pins also show a significant improvement in particle performance compared to ceramic alternatives.

Our sapphire pins are available in straight configurations, with full radiused or flat ends, or shaped ends for a perfect fit in countersunk platens. Polished sapphire rods are used as optical light guides and sensor probes, capable of operating at temperatures beyond the quartz devitrification limit and in harsh chemical conditions.

ZMSH routinely produces thousands of lift pins and guide pins each month with a diameter accuracy of 0.0005 inches and length increments as fine as 0.0002 inches. We also provide laser marking services. Our capabilities and capacity allow us to support any lift pin application, including necessary measurements, cleaning, and certifications.
