About Leaf Chains

Leaf chains were the first series of ANSI leaf chains and continue to be widely used today. They offer numerous advantages, including lightweight design, high strength, corrosion resistance, good conductivity and thermal properties, easy maintenance, and compact design.

The manufacturing process of the AL series leaf chain usually includes the following links:

1. Raw material preparation: This link involves purchasing and storing raw materials, such as aluminum ingots, steel or stainless steel, etc. The quality of raw materials directly affects the performance of the final product, so quality control of raw materials is crucial.2. Smelting and casting: Smelting is heating raw materials to a molten state to form molten aluminum. Casting involves pouring molten aluminum into a mold and cooling it to form a preliminary casting. This link is the basis for manufacturing the AL Leaf chain, ensuring the basic shape and size of the product.3. Heat treatment: The heat treatment link is to heat or cool the preliminary casting to change its internal structure and performance. Heat treatment can improve the strength, hardness, wear resistance, corrosion resistance, and other properties of the material, laying a solid foundation for subsequent processing.4. Cutting and bending: Cutting is to cut the preliminary castings after casting according to the required specifications so that they can meet the requirements of subsequent processing. Bending is the bending process of castings to form the desired shape and angle. This link is a key step in manufacturing the AL Leaf chain, and it is necessary to ensure that the size and shape of each link meet the requirements.5. Surface treatment: The surface treatment process involves painting, spraying, electroplating and other treatments on the product to improve the aesthetics and corrosion resistance of the product. This link has a greater impact on the quality and appearance of the product and requires strict quality control.6. Assembly and inspection: Assembly is to assemble the processed chain links and other accessories to form a complete AL Leaf chain. Inspection is the quality inspection of assembled products to ensure that their performance and appearance meet requirements. This link is the last step in manufacturing the AL Leaf chain and is also an important link in quality control.
