The manufacturing price of sheet metal is calculated based on the operating time

Laser cutting for 8RMB/M, calculated at 1RMB per small hole

CNC pricing of 5RMB/Min

CNC bending pricing: 1 RMB per side, double the price for the larger side

Cold work welding calculation is 70RMB per day, with 50KG per working day as the benchmark

The above calculation methods require a high level of comprehensive quality and a strong understanding of industry trends, which means they are difficult to operate

The following sheet metal calculations are empirical formulas that do not consider manufacturing processes:

Material price=unfolded weight of material dropped x market material price

Processing fee calculation: without considering process, tax, management fees, and shipping costs

Benchmark calculation: 3200RMB/T cold-rolled steel plate t=2.0 1804-m Grade 7 IT7

Cold work processing cost: 8.0-8.4RMB/KG, with workers producing 50KG or more per work,

Cold work includes the following: grinding wheel machine cutting, old style shearing machines, old style bending machines, flame piercing, old welding, and outsourcing prices ranging from 7.2 to 7.5 RMB/KG.

The above processing coefficient base is set to 1.

The outsourcing costs for CNC cutting, CNC punching, CNC bending, and CO2 shielded welding are calculated with a coefficient of 2.5-3.5, and the coefficients are taken into account based on the number of processes and complexity.

Laser cutting is twice the impact;

When the board is not equal to 2, the processing cost is calculated as equal to 2

When the plate size is less than 1.2, the processing cost is multiplied by 2.5 to 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 is multiplied by 0.75 to 0.85, usually taking the larger value;

When the tolerance level is increased to 1804-f, the counting coefficient is multiplied by 1.5-2;

For batch deburring and blunting, multiply the counting coefficient by 1.1 to 1.5;

The surface spray price is 20-30 RMB/m2;

The price for surface three degree paint processing is 15-20RMB/m2;

For those with special requirements and difficulties in manufacturing and processing, it is necessary to consider the yield 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 approximately 28% to 35%. After deducting taxes, the profit is around 18% to 23%. If there is a requirement for profit, the corresponding multiplication coefficient should not be less than 1.75 when pricing
