How do we calculate the cost of hardware?

Unit price = {Material fee + [Processing fee * (1 + tax 17%)]} * [1 + loss fee (4%) + management fee (5%) + profit (10%)]

1. Calculation of material cost:

Total material weight * material price-(total material weight-product net weight) * waste recycling price

⑴ Calculation of unit weight:

① Cylindrical: πr∧2 * density* 10∧-6 ② Stamping sheet: length*width*thickness*density*10∧-6

⑵ Stamping parts margin size: Stamping part thickness (T) Unilateral margin T≤0.5mm 1.2mm 0.5mm＜T≤1.5mm 1.5mm T＞1.5mm 2.0mm

⑶ Density of commonly used materials: Material name Density g/cm3 (t/m3)

⑷ Commonly used material price:

Material name Tax included (17%) Price (yuan/Kg)

⑸ Waste recycling price: name of material price (yuan/Kg)

2. Redemption fee:

A product is often composed of multiple processes, and each process may use a different tonnage press. Now the different tonnage beer machine is punched once.

3. Machining fee:

Types of processing machine tools Charge per hour (RMB), traditional machine tools (turning, milling, surface grinding, internal and external grinding, etc.)
