What are the formulas for calculating the quotation of plastic molds?

The quotation formula of plastic mold involves a number of factors, including the complexity of the mold, material selection, production quantity, processing fees, additional costs, etc.

The following 4 are some of the main common formulas:

(1) Mold complexity calculation:
Mold complexity is usually measured in terms of the projected area of the mold (A) and the apparent area of the mold (A’). These two values can be measured by CAD software. The complexity calculation formula is: K=A/A’, where K is the mold complexity.

(2) Material cost calculation:
Material costs include mold materials and machining materials. The cost of mold materials is usually calculated according to the type of material, weight and price. The cost of processing materials is calculated based on the quantity and price of materials used in the processing process.

(3) Calculation of processing costs:
Processing costs include machining, electrical machining, grinding, milling and other costs. The calculation of processing costs is usually determined by processing time, equipment use time, operator skill level and other factors.

(4) Calculation of additional charges:
Additional fees include design fees, drawing fees, programming fees, inspection fees, transportation fees, taxes, etc. These costs are calculated on a case-by-case basis and are usually billed separately for each cost.

After taking the above factors into consideration, a final offer can be obtained based on experience. Of course, different companies may have different quotation calculation methods, which need to be adjusted and negotiated according to the actual situation.

It should be noted that the above calculation formula is only a rough reference, and the actual offer needs to be adjusted according to the specific situation. At the same time, in order to get a more accurate quotation, it is recommended to conduct a detailed analysis and evaluation of the details of the mold before calculation.
