Metal stamping tool and die design considerations
When designing metal stamping dies a tool and die maker or tool and die designer must have the following information prior to start. There are several types of tools that could be built for the same part. They have special purposes to best suit both parts and metal stamping production.
The cost of the tool and die to be produced may be greatly affected by the following considerations:
If the amount of 2000 is for a day or for a week and possibly for many years to come, then you must build a tool that lasts, very efficient and easy to use or has the capability for automation. The customer may have a request for manual, semi-automated or fully automated part production.
The cost of the tool and die to be produced may be greatly affected by the following considerations:
Estimated number of metal stamped parts the tool and die should produce monthly, yearly, or in total
Eg. if the customer needs 2000 parts in total and possibly never again, then it is not wise to build a tool designed for high volume metal stamping and productivity. Make something simple and inexpensive, yet produce the correct metal stamped parts.If the amount of 2000 is for a day or for a week and possibly for many years to come, then you must build a tool that lasts, very efficient and easy to use or has the capability for automation. The customer may have a request for manual, semi-automated or fully automated part production.
The quality of the metal stamping part
Some production parts may require absolute burr-free edges without a second operation to remove the burrs. Some metal stamping production parts require straight edges all the way. Other stamped parts have such tight specifications that special tools need to be built for that request.Punch press
The metal stamping die must physically fit the punch press it is intended for, so you need the punch press specifications that may limit how you build the tool.The metal stamping part itself
Some metal stamped parts are best suited for a certain type of tool and die design for the best result. Don’t try to build something else, if you are not sure of the outcome. To decide what type is the best for that part, take a look at the sample designs, made for the same part. Vortool Manufacturing will discuss each version’s strong points that can help you to make a decision about which to choose.Progressive die - two progression blanking tool design

Metal stamping tools are essential for producing components in a cost effective way. In order to reduce the cost per unit, parts must be made faster, more accurately and reliably. This actual project was focused on a criteria that was essential to the design and the building of this tool. This information helps to choose the type and number of features to design as well as selecting tooling components and the right materials to be used etc. As a result, the tool will have all the necessary functions, nothing less and nothing more that will keep the budget under control.
A special package was created with super detailed shop drawings, a Bill of Material and special illustrated instruction pages how to build the components properly and then the best way to operate the tool once in production. As an addition there were instructions about punch press preparations and set up information that ensures trouble free production time after time.
Based on European precision and decades of experience, any tool design produced by Vortool Manufacturing is the most comprehensive design method that any company could ask for. The tool will fit the press or presses with no surprises.

Stamped metal parts usually require more than one operation in one. This progressive metal stamping tool produces a high volume mounting bracket that pierces holes, blanks out a shape by cutting the strip into separate parts and finally folds the part into an L shape. At each hit a final product falls off at the end of the tool. It is made for a high production automated punch press using coil and an air feeder for continuous operation.
This progressive die design consists all the necessary features that any stamping tool should have from ease of use through high accuracy to reliable operation for a long time. It includes strip feed and guide, stripping, slug separation, and feeder actuation. As an option the tool can be used as a manually operated tool without the air feeder using strips instead of coil.
The cutting components are designed to be made of hardened tool steel that ensures the long usability. Choosing the right alloy for the application and the proper design of the tool can greatly effect the life of the tool. As a result it can operate trouble free for longer, saving on maintenance. It can also reduce or eliminate downtime and minimize costs that are associated with the value of the final product.
The progressive tooling was designed using SolidWorks 3D CAD. Shop drawings, and files generated from the models are seamlessly fit into any machine shop or tool room's profile.
Strip layout design concept for metal stamping dies
Strip layout design concept for metal stamping
All metal stamping designs should start with the basics. A solid foundation is required with both a visual and technical guide to progress further. The strip layout is the starting point of a metal stamping design which is the foundation or plan to manufacture and build the actual tool.The strip layout design has several purposes. Once complete, it gives a visual representation to the manufacturing facility and to the client to have a good idea how the tool will work and how each progression or step will be made once the strip or coil is inserted into the die. The stamping can then begin.
This visual guide is the most important aid for the metal stamping die designer. It reveals details to clearly see how each feature must be made at each progression as the strip advances into the tool. Then important decisions can be made to simplify the final design or make it fit for automation and most importantly to improve it before it even starts.
The strip layout should include punches, form blocks, pilots, and some die blocks in order to make it clear how the tool will work and produce the parts. It is to ensure that the tool will do exactly what it is supposed to do.
Tool and die designers who neglect putting enough effort into this process, often end up with design errors. As a result, the manufactured stamping tools don’t perform well enough or don’t work at all. In that case costly modifications are necessary to correct mistakes before production can start. Usually these tools are notorious for break downs and require maintenance more often than others.
The proper tool and die design of a strip layout gives a piece of mind to the tool and die designer to proceed in the right direction. It is insurance for the end user or those who finance the project and want to be sure that their investments are in good hands with the tool working efficiently for a long period of time without breaking down. This is what it is all about. The sole purpose of a metal stamping tool is to produce as many identical high quality parts as possible at the shortest amount of time without stopping. Every time the tool requires maintenance and is not producing, it takes money away and becomes less efficient.
A good metal stamping die starts with a solid foundation, a good strip layout that gives the chance to eliminate future nuances, and to build world class tools that you can count on.

High precision metal blanking tool design
High precision blanking tool design and manufacturing
Special products require special tooling and design. Blanking thin foil type material is a challenge of its own. E.g., a 0.002 - 0.005 thickness stock to be blanked requires such small amount of cutting clearance that it is a very difficult task for most tool makers and for the equipment to do properly.
For this particular design the finished blank was made of three layers. There were two carbon film layers of 0.003 thick with a copper foil between 0.0005 thickness. The requirements were the following:
- The part must be perfect, have no bur at all.
- Part is rejected if the carbon chips off from the metal.
- Part is rejected if the carbon is separated from the metal at any given area.
The customer provided samples, made by others that did not meet the request and were then rejected.
- The above criteria was achieved by using the right amount of cutting clearance for the design that this particular material needed.
- To avoid separation of the layers, the blank must have the least amount of flexing.
- To eliminate chipping of the brittle carbon layers that were only semi bonded to the copper were another challenge.
- A gentle even holding pressure was required to hold the material while it was blanked, while reducing the travel distance of the blank inside the die cavity.
- To accommodate all of the above, the tool had to be well guided, with low impact movement with no vibration or sudden shocks.
The result was excellent as expected, and the parts came out perfect.
The combination of a good metal stamping die design and precision tool and die manufacturing was the key to this success.
