Introduction
Rotary hinges are widely used in various mechanical systems, such as doors, windows, and cabinets. The material selection of rotary hinges is crucial to ensure the reliability and durability of the mechanical systems. In this article, we will discuss the influencing factors of material selection for rotary hinges.
Influencing factors of material selection
There are several factors that need to be considered when selecting materials for rotary hinges:
- Load capacity: The material should have sufficient strength to withstand the load applied to the hinge.
- Corrosion resistance: The material should be resistant to corrosion and rust, especially in outdoor or humid environments.
- Friction: The material should have low friction coefficient to reduce wear and tear on the hinge.
- Temperature resistance: The material should be able to withstand the temperature range of the application environment.
- Cost: The material should be cost-effective and within the budget of the project.
- Manufacturability: The material should be easy to manufacture and process into the desired shape and size.
- Aesthetics: The material should have an attractive appearance and match the overall design of the mechanical system.
Materials commonly used for rotary hinges
Based on the above factors, the following materials are commonly used for rotary hinges:
- Steel: Steel is a popular material for rotary hinges due to its high strength, durability, and low cost. However, it is susceptible to rust and corrosion and may require additional coatings or treatments to improve its resistance.
- Stainless steel: Stainless steel is a corrosion-resistant material that can withstand high temperatures and has a long lifespan. However, it is more expensive than regular steel and may have a higher friction coefficient.
- Brass: Brass is a popular material for decorative hinges due to its attractive appearance and corrosion resistance. However, it is softer than steel and may not be suitable for heavy-duty applications.
- Aluminum: Aluminum is lightweight, corrosion-resistant, and has good thermal conductivity. However, it is not as strong as steel and may not be suitable for high-load applications.
- Plastic: Plastic hinges are lightweight, corrosion-resistant, and have low friction coefficient. However, they may not be as strong or durable as metal hinges and may not be suitable for heavy-duty applications.
