The use of sheet metal in stainless steel door hinge manufacturing introduces an efficiency that optimizes the entire production process. The shape of the flat sheet enables exact cutting and shaping using a punch press, which makes both handling and storage more efficient. This results in increased product consistency, elevating the quality and uniformity of the final hinges. While sheet metal is nonmagnetic and has some effective functions, its performance has limitations compared to investment casting. Despite its minor magnetism, investment casting brings superior strength and corrosion resistance to the hinges, making it a more optimal choice for heavy-duty applications.

Why Does Magnetism Exist?

Investment casting used in heavy duty stainless steel hinges production introduces minor magnetism due to a 5-20% ferritic composition inherent in the process. Unlike cast stainless steels, which require complete elimination of ferrite for malleability and rolling into sheets, investment-casted steels don’t need this. Consequently, ferrite remains, enhancing the hinge’s strength and corrosion resistance, making it apt for weight-bearing residential and outdoor use. So, when you get these meticulously designed hinges, you acquire durability and detailed workmanship.

Waterson Stainless Steel Hinges Material Explained

While many door hinges on the market are produced from sheet cast material, suited for mass manufacturing through a punch press, Waterson uses an alternative method – investment casting. This technique has its benefits when crafting heavy duty stainless steel hinges. It allows for a larger barrel to be fashioned, accommodating our patented enclosed mechanism design. Not only does this promise increased durability and enhanced functionality, but it also enables small-batch customization, an attractive proposition for those seeking unique hardware solutions. Among the variety of stainless steel options available, you’ll find types like 304, 316, and marine grade 316L. As you navigate our page, you’ll encounter the different looks of finish types across our brand’s offerings and see how our approach differs from traditional door hinges departments.
