Cast Iron Weights

---

Veidt Weighing is a cast iron weight factory in china, cast iron weights are a traditional measuring tool mainly used for calibration, inspection, and verification of various weighing equipment. As a standard instrument for quality transmission, cast iron weights play an important role in industrial production, commercial trade, laboratory research, and other fields.

Characteristics of cast iron weights

1. Material characteristics: Made of high-quality gray cast iron or ductile iron, with high density and stability
2. Strong durability: The surface is usually treated with rust prevention, resulting in a long service life
3. High cost-effectiveness: Compared to stainless steel weights, cast iron weights are more cost-effective
4. Complete specifications: ranging from 1kg to 5000kg, meeting the needs of different occasions

Manufacturing process of cast iron weights

1. Raw material selection: Select high-purity pig iron and strictly control the content of elements such as carbon, silicon, manganese, etc
2. Casting process: sand casting or precision casting is used to ensure that the internal structure of the weight is dense
3. Mechanical processing: Precision machining is performed on the cast blank to ensure precise geometric dimensions
4. Surface treatment: sandblasting, spraying or electroplating treatment to improve rust prevention performance
5. Metrological verification: verified by a professional metrology institution and issued with a verification certificate

Precautions for use

1. Before use, the surface of the weight should be checked for rust and damage
2. Special tools should be used during transportation to avoid direct hand contact
3. The storage environment should be kept dry and ventilated to prevent moisture
4. Regular inspection to ensure measurement accuracy
5. Different levels of weights should be stored separately to avoid confusion

Maintenance and upkeep

1. Regularly clean the surface of dust and dirt
2. Slight rust can be lightly sanded with fine sandpaper and then reapplied with anti rust oil
3. When not in use for a long time, rust proof oil should be applied and covered with a dust cover
4. Check the status of the weights every six months

As a traditional measuring tool, cast iron weights still play an important role in modern measurement systems due to their stability, reliability, and economy, and are indispensable basic measuring instruments.
