Die for production, the mold material is loss, if the heat is not enough waste caused by waste
First of all need to consider the loss of plastic parts because of what causes.
Mold change, the mold material is loss, if the heat is not enough waste is wasted, and then produce the nozzle.
Appearance of the pieces, the higher the color requirements, the amount of water mixed with smaller, more mixed with the intake of vase. In general, 1 ton of material inputs, if the qualified products produced only 0.7 to 0.8 tons of products. This can be defined loss rate of about 20% to 30%, relatively safe. Finally, the remaining outlets need to be considered for the next batch of production, or how to deal with. Other cost calculation is similar to the plastic parts offer = plastic parts weight * 1.03 * pieces of plastic parts processing fee + post-processing costs (fuel injection, plating, etc.) + packaging + transportation + management fees + profits. |
