  • Stainless Steel: stainless steel is one of the most used materials in hinge production. This iron alloy produces excellent corrosion and rust resistance due to the presence of carbon inside it, making stainless steel the most popular material in comparison to other materials.
  • Bronze: it is a strong material that provides features such as corrosion resistance and protection from friction with other metals. Though they are slightly more on the pricier side than a few other materials, bronze is a fifth material to manufacture hinges.
  • Aluminum: Aluminum is a pure metal and provides anti-rust properties much like stainless steel.  Not only are they lightweight and affordable than other materials, aluminum hinges are manufactured to withstand humidity.
  • Brass: Brass hinges are more malleable than other materials but aren’t comparatively as common as stainless steel. They are easily formed and controlled than several other materials. However, brass hinges can be prone to cracking due to stress or extreme conditions. Brass hinges are more suitable for low-stress portals.

Step-by-step Hinge Production

Hardware manufacturing has evolved over time in order to maintain our budget without undermining its quality. Whether we need door hinges for residential or commercial applications, these are some of the crucial steps in the manufacturing process that give us a better understanding about our portal needs.  

1- Thermal Treatment: 

Hinge manufacturing includes a crucial step of thermal treatment in which the materials are heated in smelting units to transform their malleability. In order to make them more moldable, materials are melted to form various shapes to alter the chemical composition.

2- Machining

This step is crucial to ensure that the materials are correctly flattened, deformed or cut into the hinge component. These machining methods involve casting, deformation, cutting and extrusion.

3- Secondary Hinge Production

When the initial step of hinge production has completed, there are multiple processes that include protection treatment for deterioration. This instance occurs when some of the metal from the hinge is worn away. Many door hinge suppliers and manufacturers collect and assemble hinge pieces with ball bearings in the middle of each joint to ensure smoother movement of the door hinges.

4- Finishes

In order to ensure a longer lifespan, aesthetic value and overall design of the hinges, the hinges undergo finishing processes such as polishing, rust-proofing, smoothing and painting. This process is done to improve the decorative appeal of the door hinges and ensure quality assurance. In this process, manufacturers also double-check to align the door hinges properly to accommodate all the requirements of the hinge’s application.
