The production of custom-weighted iron has distinct characteristics that are different from other processes. The main features include wide adaptability, the need for a large amount of materials and equipment, and environmental pollution. The production of weighted iron generates dust, harmful gases, and noise, which cause severe environmental pollution compared to other mechanical manufacturing processes. Measures must be taken to control this pollution. The accuracy of the castings and the economic performance of the production process mainly depend on this process. In many modern weighted iron workshops, the molding and core-making have been mechanized or automated. Common sand mold molding and core-making equipment includes high-pressure, medium-pressure, and low-pressure molding machines, sand polishing machines, boxless injection molding machines, core injection machines, cold and hot core box machines, etc. 

Some counterweight castings of loaders also require post-casting processing due to other requirements, such as heat treatment, rough machining, etc. The counterweight iron is a relatively economical method for blank forming, and it demonstrates its economic advantages for components with complex shapes. For example, the cylinder blocks and cylinder heads of automotive engines, ship propellers, and other artworks. For some difficult-to-machine components, such as nickel-based alloy components of gas turbines, the counterweight iron method cannot be used for forming. Additionally, the size and weight of the components of the counterweight iron have a wide range of adaptability, and the metal type is not restricted; the components not only have general mechanical properties but also have comprehensive properties such as corrosion resistance and vibration absorption, which cannot be achieved by other metal forming methods such as forging, rolling, welding, and stamping. 

Cast iron parts are the main products of our company. The cast weight blocks can be customized according to customer requirements in terms of shape for easy installation. Due to the high density of cast iron, they can achieve a significant load balancing effect in a limited space, being both aesthetically pleasing and practical. From an environmental perspective, after several years of use, they can be recycled, making them more economical. The cast iron for ballast is small in size but heavy in density, and is indispensable in the balance of ships and submarines. This product is always stocked with a large quantity of available stock. 

Weight blocks are widely used in various industries and fields for purposes such as load balancing and traction. They are also widely applied in various industries on large mechanical equipment, such as in construction machinery, for example, excavator weight blocks, forklift weight blocks, loader weight blocks, crane weight blocks; for tractors used for transporting goods, when the load is too heavy, weight blocks are placed at the front or rear of the vehicle to increase the friction of the tires and thereby enhance traction; in our daily use of fixed-line telephones, weight blocks are also commonly used in the handset to increase the weight and feel of the device, etc.
