How to Create an Injection Molding Cycle Time Calculator in Excel: 5 Methods

Method 1 – Input the Required Values

Click on cells as shown below and insert the required value from your production particulars at the Sample Dataset worksheet.

Click on cell C5 and insert the name of your material (PVC (soft) here).

Click on cell C6 and insert the value for the thickness of your material (6 here).

Insert the required times in the following cells in the image below. You can input these values from the given range in the Sample Dataset worksheet.

Method 2 – Calculate Total Injection Time

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

Press the Enter key.

Click on cell C8 and insert the formula to calculate the total injection time.

=ABS((C7/20)-(0.5*'Sample Dataset'!C8))+'Sample Dataset'!C9

Press the Enter key.

Method 3 – Calculate Total Melting / Charging Time

Click on cell C11 first.
Insert the following formula and hit the Enter key.

='Sample Dataset'!C12/'Sample Dataset'!C13

Get the total charging time.

Method 4 – Calculate Total Cooling Time

First and foremost, click on cell C12.
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))

Hit the Enter key.

Find the injection molding cycle’s cooling time in the given table.

Method 5 – Calculate Total Injection Molding Cycle Time

Click on cell C15 and insert the following formula.

=SUM(C8:C14)

Hit the Enter key.

Get the total injection molding cycle time. Your injection molding cycle time calculator is ready in Excel. Use the values at the proper cells to automatically find the total injection molding cycle time.

  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.

  Hello Ramesh,
  
  Thank you for your question. Currently, a ready-made Excel data-entry format for injection machine parameters is not available in this specific article. However, you can easily create one by following the steps below:
  
  1. Identify the key parameters you want to record
  Typical fields include:
  Material type
  Melt temperature
  Mold temperature
  Injection pressure
  Shot size
  Cooling time
  Cycle time
  Part weight
  Machine tonnage
  Notes/Operator name
  
  2. Open a new Excel workbook
  Create a clean sheet that will work as your data entry form.
  
  3. Arrange the input fields in a table
  Place the parameter names in the first column (A), and keep the second column (B) for entering values.
  Example:
  A2: Material Type | B2: (user inputs)
  A3: Melt Temperature | B3: (user inputs)
  
  4. Add data validation
  Use Data → Data Validation to create drop-down lists for fields like material type or operator name.
  
  5. Use formulas to calculate cycle time or other dependent values
  For example,
  Total Cycle Time = Injection Time + Cooling Time + Mold Open/Close Time
  
  6. Format the sheet
  Apply borders, bold titles, and shading to make the form easier to use.
  
  7. (Optional) Protect the sheet
  Protect formula cells so only the data-entry cells remain editable.
  
  By following these steps, you can create your own customized Excel format for your injection machine data entry.
  If you need help creating a specific template, feel free to share your required fields—I’d be happy to assist.
