Stripping Force Calculator




In the realm of manufacturing, particularly in processes involving sheet materials such as metal, plastics, and composites, understanding and calculating stripping force is crucial. Stripping force refers to the force required to separate a part or piece from a die or mold after a forming or cutting process. This measurement is pivotal for ensuring that manufacturing processes are efficient, materials are utilized optimally, and product quality is maintained. The Stripping Force Calculator is a valuable tool that simplifies the calculation of stripping force, empowering engineers and manufacturers to make informed decisions and improve production processes.


The formula for calculating stripping force () typically depends on various factors, including the material properties, the shape of the part, and the type of manufacturing process. In general, the formula can be expressed as:


  • represents the stripping force, typically measured in newtons (N) or pounds-force (lbf).
  • Tensile Strength is the maximum stress that a material can withstand while being stretched or pulled before necking, which is typically measured in pascals (Pa) or pounds per square inch (psi).
  • Area of Contact is the surface area of the part in contact with the die or mold during the stripping process, measured in square meters (m²) or square inches (in²).

The specific formula for calculating stripping force may vary based on the manufacturing process and the geometry of the part.

How to Use?

Using the Stripping Force Calculator involves the following steps:

  1. Data Collection: Gather data on the material’s tensile strength and the area of contact between the part and the die or mold.
  2. Data Input: Enter the values of tensile strength and the area of contact into the calculator, ensuring that the units are consistent (e.g., pascals for tensile strength and square meters for area).
  3. Calculate: Click the “Calculate” button, and the calculator will provide you with the stripping force ().


Let’s illustrate how to calculate stripping force () using a simplified example:

Suppose you are working with a sheet of aluminum with a tensile strength of 280 megapascals (MPa) and a part with a contact area of 0.02 square meters (m²). Calculate the stripping force.

  1. Enter 280 MPa as the tensile strength and 0.02 m² as the area of contact into the calculator.
  2. Click “Calculate.”

The Stripping Force Calculator will yield a stripping force () of 5,600 newtons (N). This indicates that a force of 5,600 N is required to separate the part from the die or mold after the manufacturing process.


  1. Why is stripping force important in manufacturing?
    • Stripping force is critical for determining the force needed to remove a part from a die or mold without damaging it, ensuring quality and efficiency in manufacturing processes.
  2. How can stripping force be reduced in manufacturing processes?
    • Strategies to reduce stripping force include optimizing die and mold design, modifying material properties, and adjusting process parameters.
  3. Are there standards for stripping force in different industries?
    • Yes, various industries have specific standards and guidelines for acceptable stripping force values to ensure product quality and safety.


The Stripping Force Calculator is a valuable resource for engineers and manufacturers seeking to enhance efficiency and product quality in manufacturing processes. By accurately calculating stripping force, it enables professionals to make informed decisions about materials, processes, and tooling. In the ever-evolving landscape of manufacturing, where precision and efficiency are paramount, this calculator serves as an essential tool for optimizing stripping force and improving production outcomes.
