Stretch Forming

Stretch Forming is a time proven process used to form close tolerance shapes for the Aerospace, Military and Commercial industries. It is the primary method Versaform Corporation utilizes to form desired shapes and contours. This process allows us to create or duplicate any radii, complex contour or form using extruded shapes of varying profiles, flat sheets, square, rectangular, round or channel shapes, “I” beams or brake form shapes and offers the desired repeatability of shape from part to part.

Using this method, Versaform Corporation welcomes the challenge of difficult assignments.


The forming of Skins is an integral part of the process of the manufacture of a modern commercial or business jet aircraft. If a modern jet aircraft was perfectly round and a constant cylinder from one end to the other and the wings and tail sections were of a consistent shape, the forming of these skins would be a simple process. As the shape of a jet aircraft varies from top to bottom, end to end, “simple processes” do not apply. The manufacture of these critical skins depends on a proven process that can offer repeatability while holding critical tolerances and maintaining the integrity of the skin surface.

This process employed is the forming of skins over dies of various shapes and contours. It allows for the forming of multiple, reverse or standard contours in varying types of materials such as aluminum, aluminum lithium, stainless steel and titanium at thicknesses from .020″ thick to over .100″ thick.

Versaform Corporation has extensive experience and expertise to form the most complex shapes, involving non-standard contours with the required repeatability and precision. Our experienced operators perform this process allowing for minimal or no distortion while maintaining the required critical skin surface.



The forming capabilities at Versaform Corporation are further enhanced by employing the process of Hydro Forming, a relatively new method for manufacturing lightweight components. The Hydro Forming method uses environmentally friendly water to replace the rubber in the die cavity commonly used in Rubber Pad Forming.

This method allows for a more severe draw than in conventional methods because the pressure created by the water holds the metal tighter against the die surface to allowing for a more precise, repeatable forming process.

Stretch Draw Forming

Versaform Corporation is on the leading edge of this relatively new forming process Stretch Draw Forming. This process combines the two processes of Stretch Forming and Draw or Deep Draw Forming with excellent results involving the forming of complex or reverse contours. The implementation of this technique is replacing the outdated process of Drop Hammer forming.

The Stretch/Draw Form process is cleaner, quieter, more accurate and efficient and eliminates environmental concerns by removing Lead By-Products associated with the Drop Hammer process. Versaform Corporation is actively working with major Airframe Manufacturers to replace outdated Drop Hammer formed parts with parts produced using the advanced Stretch/Draw Form process.


Continuing our process of implementing new technology, Versaform Corporation has developed a process for forming Leading Edges for aircraft that greatly reduces material usage and scrap while increasing repeatability and productivity.

We have developed a process that replaces the outdated Bump Forming or Stretch Forming process previously used. Our process guarantees a “net fit” to the forming die that is repeated from part to part and can be used to form Leading Edge shapes ranging from Large to Knife Edge configuration. Due to the dynamics of this forming process, the required Skin Quality surface finish associated with a Leading Edge is easily maintained.


Versaform Corporation manufacturers sheet metal components using the tried and true method of Shearing and Brake Forming the required cross sections. Brake Form components make up large portions of the structural components used in Commercial and Business jet aircraft as well as structural and trim pieces for Architectural and Commercial building use. The use of multiple forming dies with varying bend radii size, allows our experienced operators to form a multitude of shapes at lengths up to 12 feet while holding critical tolerances throughout the length of the shape. These shapes can be formed from a multitude of material types including aluminum, stainless steel, and titanium.


Versaform Corporation employs two processes for the precise forming of Rings, Cylinders and Truncated Cones. The process of Ring Roll Forming is used to form plate, sheet metal sections, bars, beams, angles or extrusions into circular shapes. Rings may be formed starting with straight sections or by taking preformed rings and expanding or contracting the existing diameter to the required size. The process of Roll Forming is used to form constant Cylinders or Truncated Cones from varying thicknesses of sheet aluminum or stainless steel. These types of processes take advantage of favorable grain flow direction, offer material savings and are capable of producing close tolerances which repeat from part to part.

Hot Cold

Joggling is a process used to apply offsets in a flat or curved plane, consisting of two parallel bends, in opposite directions within a part cross section. Joggles may be applied at room temperature or at elevated or reduced temperature depending on the depth and length of the joggle combined with the alloy type and gauge. Joggles may be applied using a Press Brake or during a Stretch Form operation.

Versaform Corporation offers the ability to form the required Joggles using any of the processes, hot, cold or room temperature while applying the Joggles using the Press Brake or Stretch Form method and maintaining the required tolerances and repeatability.


Versaform Corporation continues offers the latest cutting technology with the application of our Water Jet Cutting services. Water Jet Cutting offers an alternative to flame cutting, machining, rough cutting with band saws and shearing by using a computer controlled stream of water, applied at a high rate of speed to achieve the required precision detailed flat pattern, hole pattern or shape.

Water Jet Cutting can be applied to the thinnest of materials up to the thickest and as the cutting is accomplished with water, the process is environmentally friendly. There are few limitations with regards to the types of materials that can be cut using the Water Jet. Marble, Hardened Steel, Aluminum, Titanium, Kevlar, Wood, Copper and Glass are some of the materials to which we applied this process. Because the desired shapes or hole patterns are computer developed and controlled, repeatability from part to part is maintained with ease while holding tolerances within .005″ allowing for cost effective production runs.

Sheet metal or extruded shapes are continually subjected to varying conditions throughout the manufacturing process including exposure to elevated or significantly reduce temperatures, varying limits of applied stress and multiple handling operations. These varying conditions may induce involuntary movement within the actual shape of the product resulting in a configuration that falls outside of the required engineering parameters.

Versaform Corporation offers extensive experience while employing state of the art equipment that allows for the quick and cost effective correction of the configuration anomaly thereby offering the customer a product that meets all engineering parameters.

Draw Forming

Draw Forming or Deep Draw Forming is the process of forming sheet metal components from aluminum alloy or stainless steel, between an edge-opposing punch and die, (draw ring), thereby producing the desired cup, cone, box or shell-like part configuration. The distinction between Draw Forming and Deep Draw Forming is generally related to the depth of the drawn shape versus the end result diameter or width.

In the application of standard or shallow Draw Forming, the process usually results in a shape no deeper than half its end width or diameter. Applying the Deep Drawing process will result in attaining a shape in which the depth generally exceeds more than half of the end width or diameter. As reduction (thinning) of the material thickness resulting from the draw process may occur, a multiple stage drawing process using 2, 3 or 4 individual steps may be required.

Versaform Corporation offers extensive experience in all applications of single and multiple stage Draw Forming. Our experienced Engineering Department allows for the accurate calculation of acceptable material reduction percentages to assure that the finished product meets our customers weight requirements while maintaining the necessary structural strength. The use of the draw forming technique can eliminate the requirement for the welding of seams or corners.
