Blanking and Piercing With Precision Metal Stamping in Minneapolis, MN

June 28th, 2016 · No Comments

At Thomas Engineering Company, we work with a variety of metals to create a large range of parts. The production of these different parts requires a system of quality preparation of the basic part dimensions before the more detail-oriented tooling and altering can begin. To maintain the final production quality of TEC parts, we perform highly accurate operations in the beginning stages of production. These processes are called blanking and piercing, and both are a key stage in the manufacturing of quality parts with our precision metal stamping in Minneapolis, MN.

Blanking and piercing are performed in the same physical process. Using a punch and a die, a metal sheet is cut into sections specific to the basic starting form of a part. The operations differ based on the product.

Blanking is used to cut a usable piece from a metal sheet, and the material left behind becomes scrap. Piercing is used to cut a piece of scrap from a usable cut sheet—often from an already-cut blank.

 Variants, or varying types of the blanking and piercing process, include the following:

  • Trimming cuts away unwanted edges or faults in the final stages of a part formation
  • Cutoff is a common operation used with progressive dies, and works to separate each part from the strip of parts passed through the die sequence
  • Lancing opens a slot in a metal blank that can then be bent away from the metal sheet without altering the mass of the material
  • Notching is the term for when a piercing operation is used to cut pieces away from the edge of the part or metal sheet
  • Perforating is another piercing operation used to cut several holes with close proximity to each other in a single part or metal sheet
  • Nibbling forms a contour inside or along the edge of a part of metal sheet using slots or notches that overlap to produce complex shapes
  • Shaving is an operation that is often used during the final stages of part production to remove slivers of metal from a part, increasing the accuracy of the form and part edges
