This page allows users to calculate the clamping force required for plastic injection molding. By entering the projected area of the part, the number of cavities, the projected area of the runner, and the type of plastic material, users can estimate the necessary clamping force for their injection molding process.
The user can input the projected area of the part that is being molded. This is typically the largest area seen from the direction of the injection.
The user can input the number of cavities in the mold. This typically refers to the number of parts that the mold can produce in a single injection cycle.
The user can input the projected area of the runner system. This is the channel that guides the plastic from the injection unit to the cavities.
The user can select the type of plastic material being used. The injection pressure varies depending on the type of plastic, so this is necessary to calculate the clamping force.
Please note that calculations like this are approximations and actual production may require adjustments based on specific machine, mold, and material characteristics. Always consult with a plastic injection molding expert or engineer for precise calculations.
