What Is Injection Molding Cycle Time?
Injection molding cycle time is the total cycle time for the total procedure of injection molding in industries. It includes the total injection time, pressurized holding time, charging time, cooling time, etc.
The formula to calculate the injection molding cycle time would be:
Here,
Ti = Total Filling / Injection Time
Tp = Total Pressurized Holding Time
Ts = Total Screw Driving Time
Tm = Total Charging / Melting Time
Tc = Total Time for Cooling
To = Total Time for Operating
Te = Total Drop, Robot, Ejection Time
Steps to Create an Injection Molding Cycle Time Calculator in Excel
Say, you are given the required time ranges for several sections’ required time to complete the injection molding cycle time.
Moreover, you are given a table to calculate the cooling time for various materials according to their thickness.
Now, you need to calculate the total injection molding cycle time in Excel. Go through the steps below to do this.
📌 Step 1: Input the Required Values
First, you will need to input the required values of your production materials and time values for several sections.
- To do this, at the very beginning, click on cells as shown below and insert the required value from your production particulars at the Sample Dataset worksheet.
- Afterward, click on cell C5 and insert the name of your material (PVC (soft) here).
- Following, click on cell C6 and insert the value for the thickness of your material (6 here).
- Afterward, insert the required times in the following cells as shown in the image below. You can input these values from the given value range in the Sample Dataset worksheet.

📌 Step 2: Calculate Total Injection Time
Now, you need to calculate the total injection time.
- To do this, firstly, click on cell C7 and insert the following formula to calculate the total amount of shot weight.
=('Sample Dataset'!C5*'Sample Dataset'!C6)+'Sample Dataset'!C7- Subsequently, press the Enter key.
- Afterward, click on cell C8 and insert the following formula to calculate the total injection time.
=ABS((C7/20)-(0.5*'Sample Dataset'!C8))+'Sample Dataset'!C9- Following, press the Enter key.

📌 Step 3: Calculate Total Melting / Charging Time
At this time, you will need to calculate the total charging time.
- In order to do this, click on cell C11 first.
- Subsequently, insert the following formula and hit the Enter key.
='Sample Dataset'!C12/'Sample Dataset'!C13
Thus, you will get the total charging time.

📌 Step 4: Calculate Total Cooling Time
Now, another important step is to calculate the total cooling time.
- To do this, first and foremost, click on cell C12.
- Following, insert the formula below.
=INDEX('Cooling Time Table'!B4:H16,MATCH(Calculator!C5,'Cooling Time Table'!B4:B16,0),MATCH(C6,'Cooling Time Table'!B5:H5,0))- Subsequently, hit the Enter key.
As a result, you will find the injection molding cycle’s cooling time in the given table.

📌 Step 5: Calculate Total Injection Molding Cycle Time
Finally, you will need to calculate the total injection molding cycle time now.
- In order to do this, click on cell C15 and insert the following formula.
=SUM(C8:C14)- Subsequently, hit the Enter key.
Thus, you will get the total injection molding cycle time. And, your injection molding cycle time calculator is ready in Excel. Just use the values at the proper cells and you will automatically find the total injection molding cycle time.

where did you get the data for cooling times?
Hello, PJ!
Hope you are doing well. Thank you for your query.
Cooling time mainly refers to the time elapsed from the end of holding pressure to the opening of the mold. This value depends on various factors like the wall thickness, product shape, mold temperature, melt properties, etc. To get a better product, the cooling time should be as low as possible.
You can search google thoroughly or visit industrial yards to learn about the actual cooling time values.
