Counterweight iron can be used as accessories for different products in different fields, which fully plays the role of increasing weight and maintaining balance. Counterweight iron is not used in large-scale machinery and equipment, but also in various industries, such as in construction machinery, such as excavator counterweight iron, forklift counterweight iron, loader counterweight iron, crane counterweight iron, The counterweight of the elevator, the counterweight of the crane, some of the counterweights in these fields are to maintain the balance and stability of their own center of gravity, and some are to make up for the light weight of the product itself to increase the weight. At the same time, the application of counterweight iron in these areas is sometimes a reasonable design choice and an economical method to apply.

The real casting of counterweight iron:

(1) The foamed plastic pattern that is vaporized when it encounters metal liquid is adopted, no need to mold, no parting surface, no core, so there is no flash burr, the dimensional accuracy and surface roughness of the casting are close to investment casting, but the size But it can be larger than investment casting.

(2) The shapes of various complex weight iron castings can be bonded by foam plastic molds and formed into a whole, which reduces the processing and assembly time, reduces the cost of castings by 10% to 30%, and also provides sufficient support for the structural design of castings. degrees of freedom.

(3) The production process of counterweight iron castings is simplified, the production cycle is shortened, and the molding efficiency is increased by 2 to 5 times compared with sand casting.

Disadvantages: The mold of solid casting can only be used once, and the density and strength of foam plastic are low, and the shape is easy to deform, which affects the dimensional accuracy of the casting. The gas produced by the shape during casting pollutes the environment.

Weight deviation of counterweight iron:

In the production process of counterweight iron, there will be weight deviation. Often the design of the counterweight iron takes into account the casting error and machining error, and the weight error of the counterweight iron should generally not exceed 10%. Whether iron can be put into use.
