Calculation Principles and Procedures of plastic mold quotation

The production of plastic products depends on the tooling, And once made a quotation system for plastic molds for the company. The cost of molds is similar to the product cost principle in ERP. material, labor, and manufacturing costs, coupled with enterprise profits, constitute the basic price.

The common formula is as follows:

Mold price = mold material fee + mold processing fee + Tax + profit

The material fee accounts for 20% ~ 30%, processing fee 50% ~ 60%; General mold profit rate: 10% ~ 30%, large mold profit margin of 20% ~ 35%

The relationship between mold time and cost is as follows:
Project time (%) Cost (%)
Design 5 ~ 15
Materials 5 20 ~ 30
Processing of conventional mould 15 10
Machining of cavity and core: 40-60 30-60 ~ 50
Manual 5 5

The production cycle of the mold is relatively short, and the type is usually around 7-40 days. From the order placed by the customer to the purchase of plastic raw materials, purchase Hot Runner, make the front mold rear mold, Mosaic, oblique top, and finally assemble and ship.

Parameter section:

1 length, widht, height mold size information: length, width, height

2 cavity, core, % sub pre-die and post-die material, percentage of total area

3 part resin, plastic raw materials for Gate Type Injection, nozzle type

4 Hot Runner supplier, Type

5 moshould base material of the die-embryo, a/B/EB Plate Material

6 special feature slider and lifter

After entering these basic parameters, click the calculation button to generate the basic price information of the mold for reference during quotation.

The basic calculation principle is then applied to the actual process of the enterprise. The quotation process is as follows:

1) when a new project comes in, the product quote will be generated by the support staff based on the customer's product requirements.

2) PM of the Project Manager checks the quotation list and submits the quotation list to GM for approval after the approval.

3) after the General Manager approves the quotation, he will generate a customer quote and send it to the customer. At the same time, he will generate a mold budget table to provide the materials, labor, manufacturing, and procurement costs required for the mold.

 

The formulas involved in the quotation calculation are summarized as follows:
