The costs of forging enterprises are divided into raw materials, fuel and power, workers' wages and surcharges, waste loss, workshop expenses and management fees.
1.Raw material: refers to the steel consumed to form the forgings entity (deducting the value of recyclable waste, such as burrs, leadies, materials, etc.). This part accounts for 50%-70% of the total cost, different steel prices are different, carbon steel is lower, alloy steel is higher. Recently, the development of the international steel market continues to be sluggish, and the expansion of the novel coronavirus strain makes the epidemic more variable. Geopolitics and trade barriers have also become superimposed factors affecting the development of raw material markets. Therefore, many raw material manufacturers will control output, thus forging enterprises will be affected accordingly. The precision forging and precision strike of servo press for raw materials can save a certain amount of raw materials for forging enterprises, make the finished products more uniform and reduce unnecessary waste consumption.
2.The fuel and power: refers to the directly used for the manufacture of forgings forging processing outsourcing and homemade fuel and power, electricity, steam, compressed air, etc.), free forging parts is given priority to with gas, die forging is given priority to with electric heating, so frequent switching should be avoided in the production of gas type, do make full use of the furnace temperature, because the furnace heat from the cooling state to require temperature will have a lot of wear and tear. The 26th United Nations Climate Conference just concluded advocated energy conservation and emission reduction, so the industry should eliminate high energy consumption and low efficiency production equipment, such as old friction press, steam hammer.
3.Moulds: refers to the moulds directly used to produce forgings. Account for 5%-20% of the total, batch, size will lead to cost changes. Choose the mold with the right material, arrange the production order according to the scientific production batch, try to avoid frequent replacement of the mold or choose inappropriate mold and process, resulting in increased mold loss.
4. Wages and Surcharges of production workers: refers to the wages and surcharges of workers who directly participate in the production of forgings. Generally accounted for more than 10%
5. Waste loss: refers to the loss caused by waste products produced in production. Accounts for about 1-5%, utilization rate of the data mainly depends on the utilization and forging parts, the former decided the material loss, waste (head, punching core material, burrs, etc.), burning loss and waste, which reflect the forging piece, margin losses, both related to forging process, overall highest temperature cold forging and die forging of medium, free forging a minimum.
6. Management fees and other expenses: expenses incurred for the management and organization of all production. Accounts for about 10-15%. Enterprises can establish a complete file management computer database, the design department accumulated information collation and centralized use.
