Hydroforming is a specialized Deep Drawing process also known as Sheet Hydroforming. Sheet hydroforming allows various materials to become complex and structurally sound parts. It allows for asymmetrical or irregular shaped geometries, while conventional Deep Drawn parts are symmetrical and uniform throughout the entire shape. Another big difference is the depth of the parts produced by each. The Hydroform Press cannot produce shapes with sharp edges or angles, and the shapes are not as deep as Deep Drawn parts.
The Hydroforming process begins by placing a laser-cut blank over a die (typically made from rubber). High pressurized water forces the blank down over the mold, forcing the blank into its new shape. Both Hydroforming and Deep Drawing are both excellent, seamless manufacturing processes that do not require any welding.
The Deep Drawing process is better suited for larger production runs, or smaller runs for applications or components that will have long-term usage. The Hydroforming process is a popular choice when producing complicated, irregularly shaped or complex parts.
At Toledo Metal Spinning Company, we use a combination of stamping, hydroforming, and conventional deep drawing for a variety of applications. One application is to utilize our press capabilities for preforming a spinning operation. One advantage for using a press preform includes the benefit of flowing the metal towards the flange of the part, giving more material in this area verses a thickness reduction from our spinning process.
Deep Draw Metal Stamping for Strength and Efficiency The deep drawing sheet metal forming process is a cold-forming metal fabrication process that is conducted in a room-temperature environment. A metal blank is stretched around a die cavity, eventually conforming to the shape of the plug, shape of the die, and the depth of the draw.
Benefits of Forming Deep Drawn Metal Stamped Parts The deep drawing sheet metal forming process is a cold-forming process performed in an environment at or near room temperature, where the metal is permanently deformed into the desired geometry. In this process, the flat metal blank is formed and stretched around a die cavity with a
What is the Trimming Process and How is it Performed? Trimming is a process used to remove excess material to achieve a desired shape, size, and finish, while removing burrs and smooths out sharp edges. To trim a part, it is put on a lathe and processed by a highly skilled metal spinner, or a
The Metal Finishing and Polishing Process The polishing process is a secondary metal fabrication process that is done to create a smooth and shiny surface by utilizing abrasives or chemical treatment, and can be done by hand or robotic automation. The purpose of adding a finish or polish is to improve the appearance by creating
The Benefits of One-piece Constructions At Toledo Metal Spnning Company, we have been forming metals since 1929. With nearly a century of experience, we have mastered a wide range of processes including laser cutting, metal spinning, deep drawing, machining, rolling and seam welding, to build strong and durable high-performance parts. But what truly sets us
The History of Deep Draw Metal Stamping What is Deep Drawing? Deep Draw forming with conventional tool and die technology is the conforming of sheet metal, commonly referred to as a blank, around a plug in either a hydraulic or mechanical press. The edges of the blank are restrained yet allowed to slide by a precise
What is Hydroforming? Hydroforming, or utilizing the hydro-mechanical-press is a metal forming process where complex and structurally sound parts with tight tolerances that can be made from various metals. A water-based fluid force, oil, gas, or a flexible elastic polymer membrane, is highly pressurized up to 10,000 PSi is applied onto a piece of metal,
Clarifying Elements to the Deep Draw Design Process – The Draw Ratio When it comes to tool design, the most important formula is The Draw Ratio, also known as Limiting Draw Ratio (LDR). The formula is: LDR = D / d D = blank diameter d = cup ID or punch diameter This ratio shows
What are the differences of Deep Drawing and Hydroforming? Hydroforming is a specialized Deep Drawing process also known as Sheet Hydroforming. Sheet hydroforming allows various materials to become complex and structurally sound parts. It allows for asymmetrical or irregular shaped geometries, while conventional Deep Drawn parts are symmetrical and uniform throughout the entire shape. Another
