National Manufacturing Co., Inc. is a world class manufacturer of deep drawn metal stampings for aerospace, defense, battery, telecomm, industrial, commercial, consumer and medical industries. A custom-engineered deep drawn metal stamping can produce a one-piece seamless enclosure. In many cases, the deep drawing process provide cost effective alternatives to casting, extrusion and machining, while significantly reducing material wastage as deep drawing allows forming of parts to near net shapes.

We work with various materials like Cold rolled steel, stainless steel, aluminum, copper, brass, Monel®, titanium, Hastelloy®, Kovar®, nickel, Inconel®, Mumetal®, tantalum and others for producing durable, high-quality deep drawn stampings. Deep Drawn Cases


As specialists in deep drawing technologies, National Manufacturing Co., Inc. has been producing precision deep drawn enclosures for over 70 years. The company is known for its tightest tolerance deep draw, and its ability to work with complex shapes, sharp corners, exotic and difficult-to-draw materials. National Manufacturing Co., Inc serves a broad spectrum of industries worldwide, including aerospace, battery, defense, electronics, fuel cell, industrial, medical, telecommunications, commercial and consumer markets.
