FMS Team has a complete injection mold and injection molding cost analysis process, and we are very willing to share with those who are looking for injection mold suppliers, injection molding suppliers and those interested in the plastic mold industry to help you evaluate a correct quotation for your project:

   Plastic Injection Mold Cost Analysis:

Mold price = material cost + design cost + processing cost and profit + VAT + tryout cost + packaging and transportation cost

The typical ratio of injection molds is:

Material cost:the ratio of materials and standard parts accounts for 15% – 30% of the total cost;

Processing costs and profits: 30% – 50% of the total cost ;

Design cost: 10% – 15% of the total cost;

Tryout: large and medium molds are controlled within 3% of the total cost and small precision molds are controlled within 5% of the total cost;

Packaging and transportation costs: follow actual calculation or 3% of the total cost;

VAT: 17%

Injection Molding Cost Analysis:

Injection molding part cost = plastic material cost + processing cost + packaging cost + transportation cost

Material cost =

[(1 + plastic material loss) * product weight * batch + debug material weight + normal scrap rate * product weight * batch] * material price / batch.

Among them, the loss of plastic materials is generally 3% -5%; the weight of general products of debugging materials is reduced, and the weight of normal waste products is 5000g – 15000g.

Depending on the tonnage of injection molding machines (made in China). Injection molding machine processing costs are different:

  Injection Molding Cost Calculation:

Product unit price = material cost + processing cost

Material cost = (actual weight + loss weight) * material unit price

Processing cost = molding cycle * price (s) ÷ cavity number (meaning the price of each part)

Increase packaging costs for special packaging requirements.

  About RFQ

When you need to send RFQ to your potential suppliers, you should try to share as much information as possible about this project with them, so that they can provide you with quotations that meet the requirements of their company:

Mold Project information

First of all, the product data is preferably 2D or 3D data in standard format, (3D data is the most popular) and the molding material you require, mold steel, mold cavity number, mold life, annual productivity, molding cycle, mold design standard, etc. .

 What is your target price?

Cost control can be achieved by eliminating unnecessary design or non-value added projects. Suppose you need 20,000 plastic parts. Do you need these plastic parts to maintain the use of this project? Or the first stage needs 20,000, the next stage needs more? The injection molding supplier/mold manufacturer will provide different solutions according to your different requirements.


Let the mold manufacturers know the production schedule, so that they can plan production well, nothing is hasty or backward.

When do you submit samples? / When do you submit the first molded parts for testing? / When do you start mass production?

 Product appearance requirements

Product appearance requirements can affect the design of the injection mold, such as gate location, parting line or insert, ejection, etc. Your supplier will need this information to determine the most economical mold design.

Molding material

The choice of molding material depends on the requirements of the plastic parts. Please tell your supplier in detail about your requirements for injection molded parts so that your injection molding plant should be able to propose alternative materials to reduce the cost of plastic parts.

 The final quantity required for this product

This is a very important message for every supplier, it will affect the manufacturing cost of injection molds, the cost of plastic parts.
