When calculating the cost of leather coin purse processing, it is mainly calculated for the amount and unit price of various raw materials, loss rate, packaging cost, and processing cost. Raw materials include cowhide, sheepskin, snakeskin, crocodile skin, zipper, hardware accessories, textile materials, non-woven materials, edge oil, glue, thread, etc.
Calculation formula for leather consumption in coin purse processing: total area of parts ÷ 144 × (1 + loss rate) = use of skin
However, small and rare special leathers, such as pearl skin, crocodile skin, snake skin, ostrich leg skin, turkey claw skin, etc., do not calculate the loss.
The zipper is measured in English size and converted into code numbers; the hardware accessories are calculated according to the number of practical numbers or sets. The amount of oil, glue and thread occupies a very small part of the cost of the wallet in the cost of a product. Generally, the actual amount of the wallet is not strictly calculated, but a value-preserving parameter is obtained by the monthly inventory result of multiple materials. . These parameters are commonly accepted standards in the technical exchange between the factory and the factory.
