Materials and Manufacturing Processes of Concealed Hinges

Concealed hinges are commonly used in furniture and cabinet doors, providing a clean and modern look without visible hinges. The manufacturing of concealed hinges involves various materials and processes.

Materials:

1. Stainless steel: Stainless steel is a popular material for concealed hinges due to its durability, corrosion resistance, and strength.
2. Zinc alloy: Zinc alloy is another commonly used material for concealed hinges. It is lightweight and has good corrosion resistance.
3. Aluminum alloy: Aluminum alloy is a lightweight material with good strength and corrosion resistance, making it suitable for concealed hinge applications.
4. Brass: Brass is a material that is commonly used for decorative concealed hinges due to its attractive appearance and corrosion resistance.

Manufacturing Processes:

1. Casting: Casting is a common method used to manufacture concealed hinges made from zinc alloy or aluminum alloy. The material is melted and poured into a mold to create the desired shape.
2. CNC machining: Computer numerical control (CNC) machining is a precision manufacturing process that uses computer-controlled tools to shape and form the material. CNC machining is often used to produce stainless steel and brass concealed hinges.
3. Stamping: Stamping is a process that involves shaping a flat sheet of metal into the desired hinge shape using a press. This method is commonly used to produce concealed hinges made from stainless steel.
4. Injection molding: Injection molding is a manufacturing process that involves injecting molten plastic into a mold to create the desired shape. This method is commonly used to produce plastic concealed hinges.
5. Welding: Welding is a process that involves joining two pieces of metal together using heat and pressure. This method is commonly used to assemble concealed hinges made from stainless steel or aluminum alloy.

Overall, the choice of material and manufacturing process for concealed hinges depends on the specific application requirements and the desired aesthetic and functional characteristics of the hinges.
