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.

2、 Scope of application: General weighing scales, platform scales, etc.

Material: Cast Iron

Surface treatment: environmentally friendly paint coating

Packaging: Wooden crate or wooden pallet Structure: Lock type

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

When abnormal phenomena are found in precision cast iron weights, such as uneven surface, burrs, rust spots, inaccurate scale, bent and deformed ruler body, inflexible movement, etc., users should not disassemble and repair them by themselves, and are not allowed to use rough methods such as hammering, filing, sanding, etc. to repair them, in order to avoid increasing the error of cast iron weights. If the above situation is found, the user should actively send the measuring station for maintenance and continue to use the cast iron weights after their accuracy has been verified.

Stainless steel weights:

1mg weight, 2mg weight, 5mg weight, 10mg weight, 20mg weight, 50mg weight, 100mg weight, 200mg weight, 500mg weight. The milligram weight is a sheet-like weight without weight markings. Identification method: Triangular shapes represent weights with the number 1, such as 1 milligram weight, 10 milligram weight, and 100 milligram weight, all of which are triangles; The quadrilateral represents the weight with the number 2, such as the 2 milligram weight, 20 milligram weight, 200 milligram weight. In addition, there are two weights with the number 2 in the set of weights; A pentagon is a weight with the number 5, such as a 5-microgram weight, a 50mg weight, a 500mg weight, and then comparing the sizes will determine the weight. 1g weight, 2g weight, 5g weight, 10g weight, 20g weight, 50g weight, 100g weight, 200g weight, 500g weight, 1kg weight, 2kg weight, 5kg weight, 10kg weight, 20kg weight, 25kg weight, etc. These are commonly used specifications in weights, which can be combined into other specifications using addition. For example, 1kg weight+2kg weight is 3kg weight, and 2kg weight+2kg weight is 4kg weight. We can also customize special specifications according to our own needs.

Tips for selecting cast iron weights

‌1、 Material identification‌

‌Raw materials and processes‌

Preferred use‌Secondary purification of grey cast iron‌Weight (carbon content)2.7%-4.0%）Its density is stable（7.0-7.3g/cm³）High toughness, can reduce the risk of handling fracture‌14.

Beware of low-quality weights with "steel slag": the exterior is made of steel plates, and the interior is filled with waste iron slag or cement blocks. When struck, the sound is hollow and the volume is larger than that of standard weights10%-15%‌14.

‌surface treatment‌

The surface of high-quality weights should‌Smooth and burr-free‌, usingR3Rounded anti-collision design, chrome plating thickness ≥0.05mmCan significantly extend the rust prevention cycle‌36.

‌2、 Grade and accuracy selection‌

‌Grade Classification‌

according toJJG99Standards are divided intoM1toM22Grade, commonly used in industrial scenariosM1Grade（20kgError ≤±0.1g）The laboratory needs to be selectedE2Grade and above‌28.

The higher the level, the heavier the weight‌The lower the uncertainty‌, requires supporting facilitiesCNASCertified calibration certificate‌37.

‌Magnetic susceptibility control‌

Magnetic susceptibility ≤0.05%The symmetrical interference of the weight is smaller, and it can be detected by approaching the magnet to avoid error compensation caused by high magnetization‌38.

‌3、 Appearance and process validation‌

‌Identification and Structure‌

Legitimate weights must be cast with clear markings‌Weight identification‌No welding marks or rough lead injection holes‌13.

The locking structure weight is suitable for high-altitude work scenarios and can be stacked in multiple layers to reduce the risk of slipping‌15.

‌detection method‌

‌Percussion test‌High quality gray cast iron has a dull and uniform sound, while inferior products produce abnormal noises‌16.

‌volume comparison‌Under the same weight, the volume of steel slag weight is larger than that of standard weight10%-15%‌6.

‌4、 Scene adaptation and cost control‌

‌Scenario requirements‌

Choose chrome plated models for humid environments and lock type structures for frequent handling scenarios‌14.

The laboratory requires a constant temperature and humidity environmentE2Grade and above weights, and each6Monthly re inspection‌38.

‌Cost effectiveness optimization‌

The cost of cast iron weights is lower than that of stainless steel60%However, it is necessary to avoid the low price trap and prioritize the use of integral casting technology (without welding seams) products‌46.

When purchasing, the option of "daily testing with dual weights" can be chosen to reduce calibration costs and time‌7.
