DIN764 Standard Link Chain Features:

• Precise size and strong adaptability. Strictly follow the DIN764 standard production, the chain ring diameter is commonly 5-12mm, the pitch is 15-30mm, and the dimensional tolerance is controlled at ±0.2mm (common conveyor chain ±0.5mm). Taking the 8mm diameter chain as an example, the ring length is 18mm, the ring width is 12mm, and the aspect ratio is 1.8. It can accurately mesh with various standard sprockets. The beating amplitude during transmission is ≤0.8mm. It is suitable for conveyor equipment of different brands, reducing the difficulty of installation and debugging and improving the stability of equipment operation. The welding process adopts resistance butt welding (carbon steel) or argon arc welding (stainless steel), and the weld is smooth (height ≤0.4mm), which ensures the connection strength and surface flatness of the chain ring and reduces scratches on the conveyed items.

• Various materials, environmental adaptability. The stainless steel model (1.4301) contains 18% chromium and 8% nickel, and has excellent corrosion resistance. It is suitable for food and beverage production lines (contact with water, acid and alkali detergents), chemical raw material transportation and other corrosive environments, and meets food hygiene and safety standards. The carbon steel model (C22) is quenched and tempered, with a tensile strength of 400-600MPa. It is cost-effective in dry rooms, ordinary industrial plants and other environments, and the cost is 50%-60% of the stainless steel model. Both materials have passed the DIN standard bending test (180° bending without cracks) and tensile test (yield strength ≥250MPa).

• Smooth transmission, high efficiency and energy saving. The chain ring adopts a "smooth inside and outside" design, and the contact area with the sprocket is increased by 25% compared with ordinary chains, and the transmission efficiency is as high as 94% (about 90% of ordinary conveyor chains). In the logistics sorting conveyor line, the 10mm diameter DIN764 chain drives the conveyor belt, and the speed fluctuation is controlled within ±1.5%, ensuring accurate sorting of goods and reducing the misdelivery rate of goods by 30%. It is suitable for German high-speed conveyors (such as the Fronius series), with an operating speed of up to 2m/s, and the chain wear rate is low, and the annual maintenance frequency is reduced by 2-3 times compared with ordinary chains.

DIN764 Standard Link Chain Typical Applications:

• Industrial Material Conveying. The parts conveying line of the automobile manufacturing plant uses a 10mm diameter carbon steel DIN764 chain to drive the tooling plate to transport automobile parts. The precise pitch control (25mm±0.2mm) ensures that the positioning error of the parts is ≤8mm, meeting the high-precision requirements of automated assembly, and the conveying volume per hour reaches 500-800 pieces. The powder material conveying system of the chemical enterprise uses stainless steel chains, which can withstand the corrosiveness of the materials and continue to operate under harsh working conditions. The downtime caused by chain failure is ≤50 hours per year.

• Food and Beverage Production. The filling conveying line of beverage bottles uses 8mm diameter stainless steel chains, which have a smooth surface without scale accumulation, can withstand 80℃ hot water cleaning and disinfection, and run 18 hours a day to ensure efficient and hygienic conveying of beverage bottles. The conveying error of each bottle of beverage is ≤3mm, ensuring the filling accuracy. The bread conveying and cooling line in the food baking workshop uses a chain to drive the baking tray to move at a constant speed. The stable transmission performance prevents the bread from deforming during the cooling process, and the product yield rate is increased to 98%.

• Agricultural irrigation and fishery. The water pump lifting system for agricultural irrigation uses a 12mm diameter carbon steel chain, which operates stably in a humid and muddy environment, lifting river water to the farmland irrigation channel, working 10-12 hours a day to ensure farmland irrigation water. The fishing net lifting device for fishery farming uses a stainless steel chain that is corrosion-resistant and can be immersed in seawater for a long time, easily lifting the fishing net, reducing the risk of damage to the fishing net and extending the service life of the fishing net by 20%.
