The weights made from pig iron through casting process are relatively inexpensive!

Common specifications include 2000kg, 1000kg, 500kg, 200kg, 100kg, 50kg, 20kg, 10kg, 5kg, 2kg, 1kg.

Common shapes include flat square and lock.

The commonly used grades are M1 and M2.

To maintain the accuracy and reliability of cast iron weights, in addition to following reasonable usage methods during use, it is also necessary to do a good job in maintenance and upkeep of cast iron weights. The correct use of precision cast iron weights such as marble cast iron weights is one of the important conditions for product quality.

1、 Do not place precision cast iron weights near magnetic fields, such as on the magnetic worktable of a grinder, to avoid making the cast iron weights magnetized.

Single cast iron weight specification (nominal value) 5000 kg、2000kg、1000kg、500kg、200kg、100kg、50kg、25kg、20kg、10kg、5kg、1kg、2kg

1、 According to the JJG99-2022 "Weights" Verification Regulations, the requirements for the appearance of weights

2、 Observe the surface roughness of the weight with visual inspection (except for engraved areas), and any scratches or marks on the surface are not considered as measurement results of surface roughness.

3、 The evaluation of surface roughness is only applicable to E-grade and F-grade weights greater than or equal to 1g.

4、 During calibration and subsequent calibration, only visual inspection is performed on the roughness of the weights.

5、 The weights, edges, and corners of each accuracy level should be rounded, and the surface should not have sharp edges or corners, as well as obvious sand holes, to prevent wear and dust accumulation.

6、 The shape of the 1g weight should be the same as the weight in the same group. If there are no grammage weights in the same group, the shape of the milligram weights should be used as required.

7、 For high-quality combination weights, in order to simplify measurement and improve work efficiency

8、 On the premise of ensuring stable quality values, it can be manufactured in a shape that facilitates the stacking and lifting of a large number of weights, in order to optimize the verification work.

9、 Special weights, as well as weights installed inside the instrument, are allowed to adopt shapes suitable for the usage conditions, but the stability of the weight's mass value, safety during use, convenience of retrieval and placement, and practicality must be ensured.

Shanghai manufacturer cast iron weight 1 ton (flat plate weight 1000kg)As a measurement calibration tool, it is familiar to everyone, but in fact, it also has another important function, which is the counterweight. It plays a very important role in the counterweight of machinery such as forklifts, the counterweight of port and dock machinery and ships, the ballast counterweight of bridge water conservancy and hydropower functions, and other fields. Cast iron weights have a wide range of applications, which requires relevant measures to prevent weight changes in order to avoid serious consequences in practical use

Precautions for preventing weight changes of cast iron weights:
1. Storage: Cast iron weights are made of iron and should be stored properly, avoiding damp and dusty environments to prevent rusting.
2. Usage guidelines: When using cast iron weights, gloves should be worn for extraction. In addition, after use, they need to be cleaned with alcohol and stored after natural air drying.
3. Daily maintenance: Regularly count the cast iron weights, clean the surface of the weights, and if there are signs of rust on the weights, they should be treated in a timely manner and coated with anti-corrosion paint.
4. Regular calibration: In order to achieve better weight of cast iron weights, it is necessary to regularly use scales and other weighing instruments to calibrate the weights. In case of mass misalignment, the cavity can be filled with tin wire to restore the standard weight of the weights, and calibration records should be kept.

Whether used as a counterweight or a calibration tool, the weight changes of cast iron weights will have a certain impact on their use. To prevent excessive weight changes, in addition to the above points, it is also necessary to send them to a professional metrology department for calibration every year according to regulations. After passing the calibration, they can continue to be put into use.
