Weighing method code 5 tons for export overseas 5000kg standard weight manufacturer
Shanghai Shirun provides: 1 kilogram standard weight, 2 kilograms standard weight, 5 kilograms standard weight, 10 kilograms standard weight, 20 kilograms standard weight, 25 kilograms standard weight, 50 kilograms standard weight, 100 kilograms standard weight, 200 kilograms standard weight, 500 kilograms standard weight, 1 ton standard weight, 2 tons standard weight, 3 tons standard weight, 4 tons standard weight, 5 tons standard weight
1、 Compliant with JJG99-2022 Weight Calibration Regulations, used for weighing instrument calibration
2、 Material: Cast Iron
3、 Level: M1
4、 Specification: 1000kg/piece, total 37 tons
5、 Surface treatment: environmentally friendly paint coating
6、 Structure: Lock type
7、 Weight quality tolerance: The tolerance is controlled within 1/3 of the normal value required by JJG99-2006 Weight Verification Regulations (if this requirement cannot be met, Party A guarantees to adjust it to the required range)
8、 Stability of Weight Quality: Within 12 months, the weight quality of the weight should meet the requirements of JJG99-2006 Weight Verification Regulations for M1 grade weights
Characteristics of cast iron weights: Beautiful appearance, smooth surface, accurate measurement, easy to use, and can be designed and manufactured in various specifications and shapes according to user needs
Cast iron weight material: secondary modified casting of raw iron. The surface is polished to a very smooth finish and coated with black paint. Non steel ladle iron (steel slag)
Due to the weight of the weight, the shipping cost should be calculated based on the actual shipping address.








Weighing method code 5 tons for export overseas 5000kg standard weight manufacturerAttention should be paid to maintenance: the warehouse where weights are placed should be clean and dry

When verifying the temperature, humidity, and weight placement, a wooden board should be placed at the bottom and covered with cloth or film at the top. Regular observation and recording should be conducted. Maintenance when not in use, remove rust on the surface of the weights, and repeatedly wipe with cotton yarn dipped in engine oil until the surface is shiny; Use a high-precision balance to weigh the processed weight, calculate the reduced mass, unscrew the screw on the weight, make up for it with tin wire, and then tighten the screw.
Technical Requirements:
1. The production method, chemical composition and heat treatment production method, chemical composition and heat treatment process can be determined by the supplier themselves, but must ensure the cast iron grades and corresponding mechanical performance indicators specified in this standard and related documents.
2. If the organization or customer has special requirements for chemical composition and heat treatment methods, they shall be specified by both parties in the ordering agreement or relevant documents.
3. Mechanical performance.
4. Mechanical properties of single cast test bars (blocks).
5. This standard measures the tensile strength of gray cast iron by processing single cast test bars into specimens, and the mechanical properties of ductile iron are based on two indicators: tensile strength and elongation as the acceptance criteria.
6. The impact test of ductile iron single casting test blocks is only applicable to the grades specified in Table 2, and the impact value is only used as the acceptance basis when the organization or customer requires impact testing.
7. Weighted iron is generally classified according to its molding method, and is commonly divided into ordinary sand mold weighted iron and extra heavy iron.
8. Ordinary sand mold breeding weight iron includes three types: wet sand mold, dry sand mold, and chemically hardened sand mold
Why choose cast iron material:
In fact, objectively speaking, there are two types of 1000kg weights: stainless steel and cast iron materials, but nowadays most companies use cast iron. The price of stainless steel is not low. Using cast iron weights can save businesses a lot of money
1: The shapes of 1000kg cast iron weights are quite diverse for our company. You can use the weights from Shanghai Shirun Industrial Co., Ltd. They can be lifted or operated by forklifts, both of which are very convenient. After all, it's impossible to lift it manually
2: Regarding the use of this weight for general electronic scales or elevator loading calibration and calibration
