In injection molding, precise clamping force ensures the mold stays closed during the process, preventing defects like flash or damage. In this post, you’ll learn the role of clamping force, how it affects production, and methods to calculate it accurately for the best results.

2024年9月24日 · Clamping force refers to the force applied by an injection molding machine to keep the mold closed during the injection process. This force ensures that the molten plastic, under high pressure, does not leak out from the mold cavity, thereby maintaining the integrity of the molded part.

Calculates the clamping force for injection molding and die casting. Clamping force indicates the amount of force that the clamping unit can apply to the mold to keep it securely closed during the injection of the molten plastic.

2023年5月23日 · During injection production, it is crucial to confirm and set the optimal clamping force based on the specifications provided in the mold manual. This involves inputting the appropriate machine parameters to achieve the desired clamping force without causing any damage to the mold.

2023年9月7日 · How to calculate the clamping force in injection moulding using the formula? A simple formula to calculate clamping force is cavity pressure (material injection pressure in kg/cm2) multiplied by the total projection area (cm2). The resulting clamping force is in kg. Force (kg)= Cavity Pressure (kgf/cm2) Total Projected Area (cm2)

2024年9月2日 · When designing a new mold, it is necessary to calculate theoretically how much necessary clamping force the mold should be installed on to achieve the best molding machine. The principle of clamping force is to extrude and cool the molten plastic injected by the injection system through the clamping system to form the shape set by the mold.

2024年10月28日 · Calculate clamping force by multiplying the total projected area of the part and cold runners by the material supplier's recommended clamp force. To ensure the success of the injection molding process, calculating the correct clamping force is crucial.

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.

We have modern brand injection molding machines with an efficient clamping force control method that keeps the mold closed effectively without causing harm. Manufacturers who collaborate with HordRT can profit from our knowledge …

2019年7月3日 · The clamping force of a plastic injection molding machine is directly proportional to the projected area runner, molding, and it must be in opposition with the clamping force. Mathematically, the clamping force formula that acts on an injection molding machine to cause it to close is calculated as;
