From the automotive to appliance industry, whenever a design demands a blend of functionality and aesthetics, a stainless steel construction is commonly given significant consideration. With three times the density of aluminum, stainless steel exhibits superior structural integrity and dent resistance. It not only offers overall brush patterns and brilliant finishes like 2BA, but also provides substantial formability and hardness. Thanks to its unmatched versatility and corrosion resistance, stainless steel is heavily employed in both indoor and outdoor environments.
Our latest video, featuring a stainless steel Lincoln liftgate part, demonstrates one of the many stainless-steel parts fabricated at GMN. As the thickness of the metal primarily drives the tonnage of the press use, the featured liftgate part is processed in a 200-ton press. The fabrication process begins by setting the press with a tool to form the flat, pre-decorated steel sheet. After the sheets are formed, the same press is set with another tool to blank the parts to size, and eventually set with a third tool to create a curved skirt around the edges of the part. In a nutshell, three different dies are sequentially installed one after the other on a single press to form, punch, and finish the flat metal sheet.
In addition to the manufacturing process showcased in the video, GMN also utilizes progressive dies to efficiently fabricate large and complex parts that require more tooling. Depending on the design intent and part size, stainless steel can be fabricated in one progressive die and/or supported with multiple secondary operations sequentially set-up on the same press to bend, coin, blank, or fold the metal. As a part of the post-fabrication process, nickel or chrome plating is frequently applied to stainless steel surfaces and edges to protect the part from harsh environmental conditions.
Whether it is a ferritic (magnetic) or austenitic (non-magnetic) alloy, GMN specializes in the fabrication of different grades and alloys of stainless steel including type 200, 304, and 430. With the ability to fabricate parts up to 40 X 15 inches and up to 1mm thickness, GMN frequently works with steel of different shapes, sizes, and tensile strength. As your one-stop-shop for metal fabrication and decoration needs, GMN also has the capability to emboss, deboss, apply selective or overall mechanical finish, and print patterns or textures before fabricating metal sheets. With global resources in supporting medium to high volume production, you can rely on GMN to help you select the most optimum alloy, process, and equipment to meet your custom metal fabrication needs.
