In-Die Services Part II: All About Staking With Metal Stamping in Minneapolis, MN

March 11th, 2016 · 1 Comment

This is Part II of a three-part series covering In-Die Services. Part I covers spot welding and Part III covers tapping.

The services we offer beyond stamping here at Thomas Engineering Company are a vital part of our mission to provide our customers with high-quality, long-lasting precision stamped parts designed for their specific needs. All of these services add form and functional abilities to a part, and our in-die alteration capabilities can streamline the production process while completing necessary operations on the assembly line. One crucial function for some parts is our in-die staking ability with TEC’s precision metal stamping in Minneapolis, MN.

Understanding the process of in-die staking requires a basic understanding of staking operations alone.


Staking is an operation that allows alterations like pins, contacts, and machine components to be connected to a part.

How it works:

The alteration component (a pin, contact, or other part) is connected to the stamped part with an interface fit.

  • Interface fits, also called press fits and friction fits, connect two parts using the friction that is created when the alteration component is pressed into the stamped part and the area is compressed.
  • A hole and boss system is used with interface fits to create a space for the protruding piece (the boss) of the alteration component to enter the space (the hole) in the stamped part.
  • When the boss enters the hole, a staking punch compresses the stamped part around the boss, forming a permanent join between the part and the alteration component.

Staking is a highly reliable method of attaching alterations to stamped parts where they are necessary for a part function. Staking is often performed off the assembly line with a specialized staking machine or by hand.

However, off-line staking increases time and costs in the production process, decreasing overall efficiency. Our in-die staking and assembly abilities at TEC eliminate the need for a separate stage in the production process as well as the expensive machinery needed for out-of-die staking. Instead, we are able to stake components inside the die on the same line as stamping operations.

Not only does this decrease costs and time, it also provides a higher quality, more precise part for our customers’ needs.
