Three Ways Metal Parts Are Made

November 30, 2021

Numerous metal manufacturing processes exist for fabricating and finishing parts. Some methods have withstood the test of time, while others are newer to the industry. Each parts manufacturing process has distinct advantages that make it ideal for specific project applications.

Sheet Metal

Sheet metal is one of the more prevalent production methods because it accommodates many different metals. Aluminum, nickel, tin, copper and steel are all good candidates for sheet metal. The base metal passes through a series of rollers designed to flatten the metal to a specified thickness or gauge.

Fabricators use techniques like press brake metal bendingturret punching and die stamping on flattened sheets. Common uses for sheet metal include automotive manufacturing and decorative elements like tin ceilings.

CNC Machining

Computerized numerical control (CNC) machining describes a parts manufacturing process automated with technology. The term is broad, as CNC includes specialized methods like milling, bending, turning and precision work. In each project, machines operate from a program based on engineering drawings. Since software controls the functions like speed and angles, results are predictable and uniform.

CNC machining has many applications in the automotive, power generation and military and defense industries.


One of the earliest known metal manufacturing processes, welding involves joining together separate pieces with a solid bond to form one component.

Typically, welding falls into one of four categories — gas metal arc (MIG), gas tungsten arc (TIG), shielded metal arc (SMAW) and flux cored arc (FCAW). MIG is typical in the automotive and building industries, while TIG is the preferred method in the aerospace industry due to a strong weld. The FCAW process is popular in construction because it’s quick and portable.

Advancements in technology have led to the emergence of robotic welding in the metal part manufacturing industry. Robotic welding produces high-quality, consistent output, maximizing profits and efficiency.

Some companies exclusively work with welders certified by the American Welding Society (AWS). The AWS develops testing criteria and industry standards to ensure these professionals are among the best.
