Top Plate Conveyor Chains are a type of conveyor chain with a flat top panel as the core load-bearing structure. They achieve stable conveying of materials through a continuous top plate surface and are widely used in industrial scenarios that require stable loading, precise positioning, or surface protection, especially suitable for conveying small and medium-sized, regularly shaped workpieces.
Material Selection:
-
Metal materials (carbon steel, stainless steel):
Carbon steel top plate chains: After surface treatment (such as galvanising, painting), they are suitable for general industrial environments. They have strong load-bearing capacity and are suitable for conveying heavy materials such as metal parts and hardware.
- Stainless steel top plate chains: They have corrosion resistance and rust resistance, and are suitable for scenarios with high hygiene requirements, such as food processing and pharmaceutical production, or humid and chemically corrosive environments (such as material conveying after cleaning processes).
-
Engineering plastic materials (PP, PE, nylon): They are lightweight, low-noise, and have a small friction coefficient. They are suitable for conveying light materials (such as plastic parts, electronic components) and can avoid scratching the surface of materials, often used in precision instrument assembly lines or the packaging industry.
Advantages:
Stable conveying: The continuous top plate surface reduces friction and jolting between materials and the chain, making it suitable for conveying fragile items, precision parts, or materials with easily damaged surfaces.
Uniform load-bearing: The top plate distributes the weight of materials to multiple chain links, reducing the force on individual components, prolonging the service life of the chain, and is especially suitable for batch conveying of small and medium-sized materials.
