[(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.
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.
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.
