Sealing performance and sealing material selection guide for double-axis hinge

Introduction

Double-axis hinges are widely used in various industries, including automotive, aerospace, and construction. They are designed to provide smooth and stable movement between two objects while maintaining their position. However, to ensure their optimal performance, it is essential to select the right sealing material and maintain its sealing performance. This guide aims to provide a comprehensive overview of sealing performance and material selection for double-axis hinges.

Factors Affecting Sealing Performance

Sealing performance is crucial for double-axis hinges, as it prevents the ingress of foreign substances, such as dust, water, and air, into the joint. The following factors can affect the sealing performance:

1. Temperature: Extreme temperatures can cause the sealing material to shrink or expand, leading to leakage.
2. Pressure: High pressure can cause the sealing material to deform, resulting in a loss of sealing performance.
3. Chemical Resistance: The sealing material should be resistant to chemicals that can corrode or degrade it.
4. Friction: Excessive friction can cause wear and tear on the sealing material, leading to a loss of sealing performance.
5. Compression Set: The sealing material should be able to maintain its shape and sealing performance even after prolonged compression.

Sealing Material Selection Guide

Choosing the right sealing material is crucial for ensuring optimal sealing performance in double-axis hinges. The following factors should be considered when selecting a sealing material:

1. Temperature Range: The sealing material should be able to withstand the temperature range of the application.
2. Chemical Resistance: The sealing material should be resistant to the chemicals present in the environment.
3. Compression Set: The sealing material should have a low compression set to maintain its sealing performance even after prolonged compression.
4. Hardness: The sealing material should have the appropriate hardness to provide an effective seal.
5. Friction: The sealing material should have low friction to reduce wear and tear on the material and maintain its sealing performance.
6. Ease of Installation: The sealing material should be easy to install and replace.
