As its name implies, a fourslide has four slides — meaning that up to four different tools, one per slide, can be used to achieve multiple bends simultaneously. As material feeds into a fourslide, it is bent in quick succession by each shaft that is equipped with a tool. Deep drawing involves pulling a sheet metal blank into the die via a punch, forming it into a shape. This type of forming is ideal for creating components that need several series of diameters and is a cost-effective alternative to turning processes, which typically require using up more raw materials.
Common applications and products made from deep drawing include:. Short run metal stamping requires minimal upfront tooling expenses and can be an ideal solution for prototypes or small projects. After the blank is created, manufacturers use a combination of custom tooling components and die inserts to bend, punch or drill the part. The custom forming operations and smaller run size can result in a higher per-piece charge, but the absence of tooling costs can make short run more cost-efficient for many projects, especially those requiring fast turnaround.
Equipment like 5-axis CNC mills and wire EDM machines can cut through hardened tool steels with extremely tight tolerances. Secondary Processing: Heat treating is applied to metal parts to enhance their strength and make them more durable for their application. Grinding is used to finish parts requiring high surface quality and dimension accuracy.
Wire EDM: Wire electrical discharge machining shapes metal materials with an electrically-charged strand of brass wire. Wire EDM can cut the most intricate shapes, including small angles and contours. Metal stamping is a complex process that can include a number of metal forming processes —blanking, punching, bending, and piercing and more. Blanking: This process is about cutting the rough outline or shape of the product.
This stage is about minimizing and avoiding burrs, which can drive up the cost of your part and extend lead time. Bending: When you are designing the bends into your stamped metal part, it is important to allow for enough material — make sure to design your part and its blank so that there is enough material to perform the bend.
Some important factors to remember:. Coining: This action is when the edges of a stamped metal part are struck to flatten or break the burr; this can create a much smoother edge in the coined area of the part geometry; this can also add additional strength to localized areas of the part and this can be utilized to avoid secondary process like deburring and grinding.
This feature is not necessary when utilizing compound or transfer type tooling but is required when utilizing progressive die tooling. Download Your Free Design Guide. Custom metal stamping describes metal forming processes that require custom tooling and techniques to produce parts specified by the customer.
A wide range of industries and applications employ custom stamping processes to meet high-volume production needs and ensure all parts meet exact specifications. Design engineers can work on a wide range of metal stamping projects for clients across various industries. A client in the medical industry approached ESI to custom metal stamp a part that would be used as a spring and electronics shield for vital monitoring equipment in the medical field.
ESI was able to meet the complex design requirements using a material stacking technique that allowed us to cut many part blanks at once, limiting costs and reducing lead times. In another instance, we were asked to redesign an existing electrical connector cover ; the client, AFC Cable Systems, was looking for a higher-quality product at a lower price with shorter lead times.
An automotive client required a high-strength, pressure-resistant metal grommet for use in Ford Transit Vans airbags. The ESI team built a station progressive tool to ensure proper development of the draw and used DDQ steel with zinc plating to ensure optimal strength and corrosion resistance. Metal stamping can be used to create complex parts for a huge range of industries. Visit our Case Studies page , or reach out to the ESI team directly to discuss your unique needs with an expert.
We could not be happier about being a customer of ESI for the past 10 years. They are extremely professional, provide excellent quality, and best of all, make working with them fun. I would recommend ESI for future stamped parts sheet metal parts in the future. The quality of work has been great and the dimensional accuracy outstanding.
Computer-aided press tool designing includes various modules like work-piece checks module, developed length blank size module, Nesting Module, Strip-Layout module, and die design module. The design check module finds out the center of pressure, tonnage required, stripping force, dimensions of punches, dies, stripper, stripper and punch plates, No.
The designing module creates the assembly drawing with many layers for various press tools elements such as Die block, die plate, punch, punch plate, stripper, stripper plate, ejector, etc. Do you have any design piercing punch from bottom with air scution at top half? If any please share it. Hi Raghvendra, What design details do you want?

Working Components Components which actually participate in forming the desired shape stamped part. Guiding or Locating Components Guiding Components maintain accurate alignment of the upper shoe with the lower shoe during the operation. Stripping Components components that remove or strip blanks and scrap from the punch or die when the operation is over. Fastening Components Fastening Components hold together all parts of the press tool as a unit.
Feeding Components Feeding Components feed the blank or metal sheet to the stamping station. Press tools should be designed in such a way that possible standard components are used for the manufacturing of products. Press tools should be designed for maximum utilization of material as well as manpower. Working Parts of the press tools must be strong and durable and replaceable when worn out.
Dimensional accuracy and surface finish must be within tolerances. Design of Press Tools The sheet metal stamping process is a very fast and precise manufacturing process. Steps to design any Sheet metal stamping press tool or die. The computing of the required force Press tonnage Selection of press Determination of shut height of the tool computing die thickness and margins Minimum cross-section Drawing strip layout and comparing material utilization Design of locating elements Selection of Hardware Drawing die plan Pillar sets, Punch height, and mounting Identify the center of pressure and checking scrap disposal Drawing Details What is Strip Layout?
The material utilization for strip layout may be calculated from the following formula — OR Theory of Press Tool Stamping Process Sheet metal cutting operations in a stamping work is a shearing process. Stressing the material beyond its elastic limit. Plastic deformation due to reduction in area fracturing starts in a reduced area. Forces Disposition The forces developed in the shearing operation is represented by a triangle as shown in the below-given figure.
Vertical Force The value of Vertical Component V depends upon the area to be sheared and the shear strength of the material to be cut. Horizontal Force The value of horizontal or lateral force H depends upon the die clearance. Importance of Proper press tool Clearance Clearance has a significant role in all cutting operations and forming operations.
The range of die clearances for various materials for stamping work: Note that the die clearances are specified in the percentage of Sheet thickness. Die Clearance for various materials Note: It is not possible to get tolerances than die clearance on components so it is necessary to perform an additional shaving operation for high precision work. Die clearance for punching press tool The hole pierced in the sheet is a tapered one, with minimum opening equal to punch size. The punch diameter will be the same as the hole size i.
Die clearance at 2. Die diameter will be same as hole size i. Bending Press Tools Principles The bending process changes the shape of a flat blank to make it angular, curved, or both without much change in its thickness. Bend Radius The minimum radius to which a blank can be bent without cracking depends upon the material and its hardness. Blank Size or Developed length It is a necessary stamping principle to calculate the length of the blank before bending because a component is usually blanked before bending.
Finding blank size for bending, forming or drawing operations. Selection for the types of press tools to be used. Calculating material utilization, pitch, margins, and angle of orientation. Deciding disposition of punches and shank center.
