What is a Stripping Die?

A Stripping Die is an auxiliary tool used after the die-cutting process to automatically remove waste material from printed sheets. Instead of manually separating waste around each finished product, the stripping die pushes the scrap away from the finished blanks, significantly improving production efficiency and consistency.

Stripping dies have become an essential component in modern packaging production, especially for folding cartons, cosmetic boxes, pharmaceutical packaging, food packaging, labels, and corrugated products.


How a Stripping Die Works

A stripping die consists of two precisely matched parts:

  • Male Stripping Board (Positive Board)
    equipped with stripping pins or ejectors.
  •  Female Stripping Board (Negative Board)
    containing accurately machined openings.

During the stripping process, the male board moves downward while the female board supports the sheet. 

The coordinated motion creates a shearing action that separates the waste material from the finished products without damaging the cartons.

This mechanical stripping process replaces labor-intensive manual waste removal, ensuring higher productivity and better product quality.


Benefits of Using Stripping Dies

✔ Reduce manual stripping labor

✔ Increase production efficiency

✔ Shorten production time

✔ Improve stripping consistency

✔ Reduce operator fatigue

✔ Minimize product damage

✔ Suitable for high-volume packaging production


Why Are Stripping Claws Important in Die Making?

In folding carton and corrugated box die manufacturing, stripping claws are essential components of a stripping die.

Their design and manufacturing accuracy directly influence the performance of the entire die during production.

Precisely manufactured stripping claws help ensure that waste materials are separated smoothly while protecting the finished carton from damage.

They also contribute to consistent die performance, especially during long production runs and high-speed die cutting.

For die making shops, producing stripping claws with accurate bending angles, stable dimensions, and good flatness makes die assembly easier and improves the overall quality of the finished stripping die.

As packaging designs become more complex and production efficiency becomes increasingly important, more manufacturers are looking for automated solutions that can produce stripping claws with higher precision and repeatability.
