This page offers practical and easy-to-use injection molding calculators including Cycle Time Estimator, Cooling Time Estimator, and Cavity Volume to Shot Size Converter. Designed for engineers and manufacturing professionals to quickly and accurately estimate critical process parameters and optimize production efficiency. Supports multiple languages for global users.
This tool helps estimate the total cycle time required for an injection molding process, including injection, cooling, and other phases.
Inputs:
Injection Time (seconds): The time taken to inject molten material into the mold cavity.
Cooling Time (seconds): The estimated time needed for the part to cool sufficiently before ejection.
Other Time (seconds): Time for additional operations such as mold opening, part ejection, and mold closing.
Usage:
Enter the values for Injection Time, Cooling Time, and Other Time in seconds.
Click the Calculate button to see the estimated total cycle time in seconds.
The result will help engineers and operators optimize and plan the injection molding production process efficiently.
Wall Thickness input is in millimeters (mm) and must be a positive number.
Thermal Diffusivity input is in mm²/s and must be a positive number.
Temperature Difference input is required and must be positive, but it is not currently used in the simplified calculation formula.
The calculation formula used is:
t=wallThickness2π2×thermalDiffusivity t = \frac{{\text{wallThickness}^2}}{{\pi^2 \times \text{thermalDiffusivity}}}t=π2×thermalDiffusivitywallThickness2
This formula provides a simplified estimate of the cooling time.
Enter the Wall Thickness (mm), Thermal Diffusivity (mm²/s), Melt Temperature (°C), Environment Temperature (°C), and Surface Temperature (°C).
Ensure the input values satisfy the condition: Tm>Ts>TeT_m > T_s > T_eTm>Ts>Te, otherwise an error message will appear.
Click the Calculate button to get the estimated cooling time in seconds.
You can toggle between English and Chinese interfaces using the language switch button.
The tool outputs the estimated cooling time in seconds, with an option to switch between English and Chinese interface.
This tool calculates the required shot size (weight of material) based on the cavity volume and material density.
Cavity Volume: The internal volume of the mold cavity, in cubic centimeters (cm³) or milliliters (ml).
Material Density: The density of the plastic material, in grams per cubic centimeter (g/cm³).
Shot Size: The calculated amount of material needed for one injection shot, in grams (g).
Simply input the cavity volume and the material density, then click “Calculate Shot Size” to get the estimated shot weight.
Supports switching between English and German languages for user convenience.
