The manufacturing cost of sheet metal is calculated based on the operation time
Laser cutting costs 8RMB/M, and each small hole is calculated at 1RMB
Numerical Control Pricing 5RMB/Min
CNC bending pricing: 1 RMB per side, double for larger sides
Cold welding calculation is 70RMB per day, with 50KG per day as the benchmark
The above calculation methods require a high level of comprehensive quality and a thorough understanding of industry trends, making them difficult to operate
The following sheet metal calculations are empirical formulas that do not consider manufacturing processes:
Material price=kilograms of unfolded material x market material price
Processing fee calculation: Excluding process, taxes, management fees, and shipping costs
Benchmark calculation: 3200RMB/T cold-rolled steel plate t=2.0 1804-m Grade 7 IT7
Cold processing cost: 8.0~8.4 RMB/KG, workers produce more than 50KG per job,
Cold work includes the following: grinding wheel cutting, old-fashioned shearing machines, old-fashioned bending machines, flame piercing, old-fashioned welding, and outsourcing prices ranging from 7.2 to 7.5 RMB/KG.
The above processing coefficient base is set to 1.
The outsourcing cost for CNC cutting, CNC punching, CNC bending, and CO2 shielded welding is taken as a coefficient of 2.5-3.5, and the coefficient is taken into account based on the number of processes and complexity.
Laser cutting is twice as fast as punching;
When the sheet metal is not equal to 2, the processing cost is calculated as equal to 2
When the sheet metal is less than 1.2, the processing cost is multiplied by 2.5~3.5
When the market price of materials fluctuates, the processing cost base remains unchanged.
If the sheet metal production is fully assembled without welding, the counting coefficient should be multiplied by 0.75~0.85, usually taking the larger value;
When the tolerance level is increased to 1804-f, multiply the counting coefficient by 1.5~2;
When performing batch deburring and blunting processing, multiply the counting coefficient by 1.1~1.5;
The surface spraying price is 20-30 RMB/m2;
The processing price for surface third degree paint is 15-20 RMB/m2;
For those with special requirements and difficulties in manufacturing and processing, it is necessary to consider the yield rate and multiply the yield coefficient;
The above pricing is the standard pricing, which means that if the scrap rate is within 3%, the profit is roughly 28% 35%. After deducting taxes, the profit is about 18% 23%. If there is a requirement for profit, the corresponding multiplication factor should be added during pricing, which should not be less than 1.75
