Veidt Weighing is a Cast Iron Weight factory in china. Cast iron weights are standard quality instruments widely used in industrial weighing, laboratory calibration, and quality testing fields. As one of the most traditional and economically practical types of weights, cast iron weights play an important role in various measurement situations due to their excellent stability, durability, and cost-effectiveness.

Main Features

Material characteristics: Made of high-strength cast iron material and subjected to special heat treatment process to ensure a dense and pore free internal structure.
Surface treatment: Spray painting or plating treatment (such as chrome plating) is usually used to effectively prevent oxidation and corrosion, and extend the service life.
Accuracy level: According to international standards, it can be divided into different accuracy levels such as M1 and M2 to meet the measurement needs of different occasions.
Temperature stability: The thermal expansion coefficient of cast iron material is moderate, and its quality is stable within the conventional temperature range.

Technical Specifications

Specification range: Common specifications range from 1kg to 50kg, and some special purpose weights can reach over 500kg
Allowable error: M1 level error range ± 0.05%~± 0.1%, M2 level error range ± 0.1%~± 0.2%
Working temperature: -10 ℃~+40 ℃ (standard environment)
Relative humidity: ≤ 80% (no condensation)

Application field

Industrial weighing: used for calibration and verification of large weighing equipment such as floor scales and platform scales
Laboratory calibration: used as a secondary standard for daily calibration of various scales and apparatus
Quality Inspection: Quality Control and Product Sampling on the Production Line
Teaching Experiment: Quality Standards in Physics, Chemistry, and Other Teaching Experiments

Precautions for use

Regular calibration: It is recommended to conduct a professional calibration once a year to ensure accurate measurement values
Correct handling: Use specialized handling tools to avoid surface damage or human error caused by manual handling
Storage environment: Store in a dry and clean environment, avoiding contact with corrosive substances
Pre use inspection: Before each use, visually inspect the surface condition of the weight to confirm that there is no rust, damage, or other issues

maintenance

Regularly clean the surface with a soft cloth to keep the weights clean
Minor rusting can be treated with specialized cleaning agents, while severe rusting should be discontinued
When not in use for a long time, rust proof oil should be applied and properly packaged
Avoid drastic temperature changes and mechanical shocks

Purchase suggestions

Choose the appropriate precision level based on actual needs, without blindly pursuing high precision
Check if the manufacturer has the corresponding production license for measuring instruments
Confirm if the weight comes with a valid calibration certificate
Consider selecting appropriate surface treatment methods based on usage frequency and environment

Cast iron weight as traditional measuring standards, still hold an irreplaceable position in modern industrial production and scientific research. The correct selection, use, and maintenance of cast iron weights can ensure the accuracy and reliability of measurement results, providing strong guarantees for quality control.
