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

Improve productivity and tool life in stamping applications, starting with selection of optimum clearance in piercing and trimming applications.
Dayton has developed punches specially designed for stamping aluminum. The combination of the right punch material, design, coating, and finish will improve your day-to-day operations
Tips for choosing tool steels, heat treatment, and surface treatments
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.
Whatever your application might be, you can be sure that die springs from Dayton Lamina provide rugged, dependable performance.
Find the recommended lubrication for ball bearing components, self-lubricating (graphite plug) components, and plain bearing components.
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.
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.
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 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.
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)?
Dayton has developed punches specially designed for stamping today's high tensile strength steels. The combination of the right punch material, design, coating, and finish will improve your day-to-day operations.
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.
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.
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.
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.
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.
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.
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.
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.
Dayton's leading-edge coatings and other unique surface treatments have been developed to improve inplant performance by increasing tool hardness and wear resistance.
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.
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.
Selecting the proper tool steel and treatment for a stamping application can be a complex and confusing process. Let Dayton explain.
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.
