Dayton Progress offers educational and other technical support services to help you build greater productivity into all your design projects.

Selecting the proper tool steel and treatment for a stamping application can be a complex and confusing process. Let Dayton explain.
Optimizing the die clearance is one of the most important steps to punching success. Too large or too tight, an improper clearance can lead to poor edge quality, reduced tool life, and more.
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.
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.
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.
Selecting the proper Tool Steels, Heat Treatment, & Surface Treatments for a stamping application can be a complex and confusing process. To simplify this process, a few basic facts should be understood. This publication will present and examine facts using terms familiar to the nonmetallurgist.
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.
Economic shortcuts in the build process almost always add to production costs in the form of increased maintenance and production scrap. To avoid these costs, initial concerns should be directed toward the type of die construction.
Tips for choosing tool steels, heat treatment, and surface treatments
Like an iceberg, most of your die costs lurk below the surface. How many times has someone compromised quality or service for price? Die Clinic assists in reducing the true cost of producing metal stampings.
This troubleshooting guide can help you determine the cause for your broken, chipped, or worn punches. It can also help you select the best solution... including Dayton products and services.
Perforating holes through one side of a round tube can present several unique problems for metal stampers. This article reviews the issues of tube deformation, punch point chipping, and slug control.
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)?
The Productivity Selector correlates different types of stock, grouped by tensile strength, type of clearance and the resultant burnish length and productivity rating. Selecting the proper Jektole Clearance can do more for your stamping productivity than any other single factor.
Perforating punch to matrix (die) clearances in metal stamping dies have been universally expressed as a percentage of stock thick-ness, and for clarity should be expressed as percent per side.
The perforation process involves driving a punch through material and the rapid failure of the material as the slug breaks free. For this reason, perforating often is mistakenly considered to be a simple two-step process.
Research and testing have revealed that a radical increase in punch-to-matrix clearance can reduce burr height to the lowest point and increase tool life exponentially. This increased clearance is referred to as engineered clearance.
