1. Material cost: (parts net weight + gate weight)/99%/98%*ABS black unit price

[99% refers to the thermal decomposition of raw materials, that is, the consumption of raw materials; 98% refers to the pass rate or the yield rate, if it is not easy to do, it can be lower]

2. Labor cost: basic salary*(1+X)*product quota/22 days/single shift output

[Note: The basic salary depends on the salary system implemented by your factory; X refers to the proportion of monthly employee subsidies, bonuses, etc.; product quota refers to all the personnel who handle the product from raw materials to shipment, which can be a decimal] ( This 22 days is a national legal working day, and it cannot be counted as 30 days! If your factory works for 30 days, then 8 days are required to be paid for overtime and cannot be counted in this way)

3. Equipment depreciation: equipment can be accrued according to the accounting year, for example, the general equipment depreciation year is 8 years. Equipment depreciation refers to the depreciation of the equipment used to produce the product.

Monthly depreciation/30 days/single shift output/day shifts/equipment utilization

(This equipment utilization rate is calculated based on the actual situation of your factory. If your equipment is fully opened 24 hours a day, then the cost is very low; if not, if the equipment utilization rate is low, the corresponding depreciation cost will be high. Injection molding The machine usually needs time for maintenance and up and down molds! Don't set the height, or you will suffer.)

4. House depreciation: House depreciation refers to the place and site expenses involved in the production of the product. Monthly depreciation/30 days/single shift output/day shift number.

(The depreciation cost should be counted as 30 days!)
5. Energy costs: water and electricity (compressed air, high-pressure nitrogen), etc., based on actual statistics.
For example, electricity bills, 24-hour power consumption * unit price of electricity bill / output per shift / number of shifts per day. Others are the same as electricity charges.

6. Other expenses: such as labor insurance supplies that need to be distributed to employees, cartons for packaging the products, and a series of low-value auxiliary supplies. These can be calculated like this: single shift use quantity * unit price/single shift output. Or: Use total quantity * unit price/total product quantity.

7. Mold cost amortization: Generally, it is calculated based on the design life of the mold. For example, 200,000 times, the mold amortization cost = mold cost X (1 + X) / 200,000. In the formula, X refers to the mold maintenance cost.
Main processing fee: electricity fee + water fee + equipment depreciation + plant depreciation + direct staff salary + maintenance cost + other auxiliary

Additional processing fee: transportation + packaging + sales cost + profit + tax

The total value of the products produced-raw material costs-labor costs-electricity costs-loss, etc. = net profit

The above costs are only in terms of the injection molding process. The cost accounting principles used when spraying are basically the same. Then add up the cost of the six items to the cost of a single product!
