At present, the market situation shows that bending processing fees are generally charged based on processing costs, auxiliary material costs, and surface treatment and spraying fees, as follows:

1. The cost of sheet metal bending processing, namely equipment depreciation sharing fee+labor cost+auxiliary material equipment depreciation amortization: Equipment depreciation is calculated based on 2 years, 12 months per year, and 22 days and 8 hours per month.

For example, for a 200000 yuan mold, the hourly equipment depreciation is 20 * 10000/2/12/22/8=47.4 yuan/hour. Labor cost: Two operators are required for each mold, and one mold loader is also required to pay. The salary is similar to that of the operator, with an average monthly salary of 5400 yuan per person. The 8-hour work schedule for 22 days per month means that the hourly cost is 5400 * 3/22/8=93 yuan/hour

2. Auxiliary material cost: Electricity and maintenance costs are approximately 2000 yuan per unit per month. Calculated based on 22 days and 8 hours per month, the cost is 2000/22/8=11.4 yuan/hour.

3. Composition of surface treatment spraying cost: Spraying cost=powder cost+labor cost+auxiliary material cost+equipment depreciation Powder cost: The calculation is based on square meters, with a powder unit price of 25-60 yuan/kg, and 4-5 square meters can be sprayed per kilogram of powder. The powder cost is about 6-12 yuan/square meter, and the labor cost is 6000 yuan/month/person for spraying. It takes 22 days and 8 hours per month, and can spray about 30 square meters per hour. Labor cost=6000/22/8/30=1.14 yuan/square meter Auxiliary material cost: Refers to the cost of pre-treatment fluid, primer, curing furnace and other auxiliary materials, which is about 50000 yuan. The monthly rate is 22 days and 8 hours, and 30 square meters are sprayed per hour. The auxiliary material cost is 50000/22/8/30=9.47 yuan/square meter, and the total spraying cost is about 10.6 yuan/square meter without the need for local protection during spraying.
