Birth of a Hole - Perforating Basics

The dynamics of the perforating process is often considered to be a simple two step process of driving a punch through a piece of sheet steel and then withdrawal of the punch from the hole.

There are in fact six steps to perforating a hole. Each step contains elements critical to the overall process. An understanding of these steps will assist in the selection of die construction, tool steels, and punch to die clearance.

Dayton Slug Control System

Dayton Slug Control is a method of reducing the risk of slugs being pulled to the die surface during withdrawal of the punch. It has no effect on hole size and will not require any changes in your regrind practices. Dayton Slug Control is effective throughout the life of the die buttons.

High Speed Stamping

This report addresses the special concerns of high-speed stamping. We define high-speed stamping and discuss operating factors - such as the effects of die clearance and methods of slug control - that will help improve your stamping operation. We explore tool steel and selecting the proper surface treatment for your application. We further describe how stripper design affects your high-speed stamping operation. Finally, we discuss application problems and possible solutions.

High Strength Steels

Auto manufacturers are challenged by increasing oil prices, stricter emission standards, and greater demands on safety. Lighter and stronger steels in structural components are now required. How does a die designer handle forming and piercing with these new High Strength Steels (HSS)?

Productivity Selector

The Productivity Selector correlates different types of stock, grouped by tensile strength, type of clearance and the resultant burnish length and productivity rating. The Productivity Rating, simply stated, shows that Jektole Clearance will produce over three times as many parts between sharpenings as Regular Clearance. Selecting the proper Jektole Clearance can do more for your stamping productivity than any other single factor.

Shear Angles

Shear Angles can be applied to all punch points. These angles are used primarily to reduce slug pulling. Single and Double Shears can be used to reduce the punching force as well as minimize slug pulling. These alterations are prepriced and do not add to the standard delivery of the product.

Shear Angles are also available on Classified Shapes, but are available as special order only.

Stamping Basics

This report defines basic stamping terminology and illustrates basic stamping functions. We explore the common types of die construction, compare stripper design options, and analyze common die operations.

The Ball Lock System

This illustrated booklet describes the features, benefits, and value of working with True-Position Ball Lock Punch & Matrix retainers. A comparison of End & Square Retainers with Backing Plates is covered, along with the inherent problems associated with these products.

Tool Steels

Tool steels refer to a variety of carbon and alloy steels that are well-suited and widely used to make tools primarily used for perforating and fabrication. Tool steels are made to a number of grades for different forming and fabrication applications.
