A single piece striker for a latch formed from stock, comprising a mounting plate with an integral striker bar. The striker bar extends out from the mounting plate via a neck portion. The engagement area of the striker bar has a greater diameter than the thickness of the mounting plate. The striker is formed using a progressive die. The striker bar is formed by compressing a portion of the stock to a greater thickness than the rest of the striker. Compressing a portion of the stock also provides a rounded engagement area across the length of the strike bar. Compression occurs over a series of dies that provide a progressively rounder shape. Locator channels within the dies help retain the striker bar during compression.

What is claimed is: 1. A method for manufacturing at least one single-piece striker for a latch from a stock of a first thickness using a progressive die, each striker comprising a mounting plate, a striker bar, and a neck portion connecting the striker bar to the mounting plate, the method for each striker comprising the steps of: punching or cutting a selected shape out of the stock; forming at least one mounting plate in a respective portion of the selected shape; creating a void out of another portion of the selected shape by one of punching or cutting techniques, thereby defining a striker bar portion with a width greater than the first thickness and defining the neck portion adjacent the striker bar; compressing and rounding the striker bar portion to create the striker bar having an engagement area that is thicker than the first thickness; cutting the selected shape from the stock; and bending the selected shape along the at least one mounting portion to form the striker. 2. The method of claim 1, wherein compressing the striker bar portion of the stock further provides a rounded engagement surface for the striker bar. 3. The method of claim 2, wherein compressing the striker bar portion of the stock is done using a series of dies having a progressively rounder shaper. 4. The method of claim 3 wherein at least some of the dies in the series of dies includes locator channels to retain the striker bar during compression. 5. The method of claim 4, wherein the depth of the locator channels decreases progressively over the series of dies that include locator channels. 6. The method of claim 5, further comprising creating at least one mounting hole out of the mounting area using at least one of punching or cutting techniques. 7. The method of claim 6, wherein the stock is a coil stock. 8. The method of claim 7, wherein the coil stock is SAE 410 steel. 9. The method of claim 8, wherein the first thickness is one of equal to and less than 3 mm, and the second thickness is at least 6 mm.
