What Are the Processes in a Metal Fabrication and Engineering Company?

Metal fabrication is an industry that involves the creation of metal structures by cutting, bending, and assembling processes. This practice forms the backbone of many sectors, making it an essential process for many businesses, governments, and individuals worldwide. But what exactly are the core processes involved in a metal fabrication and engineering company? Read on to find out more.

Core Processes in Metal Fabrication and Engineering

It’s important to understand the core processes within metal fabrication and engineering. Usually, these core processes can be broken down into four main areas: cutting, forming, assembly, and finishing.

1. Cutting

The first phase usually involves cutting the raw material into the desired shape and size. Here, metal fabrication companies often utilize various techniques to achieve this, including sawing, shearing, chiseling, or with technology such as lasers and plasma torches.

Metal laser cutting services utilize highly focused light beams to cut through metal, rendering high levels of precision, especially for complex shapes and sizes. This cutting technique yields cleaner, more crisp edges than traditional cutting methods.

2. Forming

Once the material has been cut to the correct dimensions, the next step involves forming it into the required shape. This action usually requires bending or stretching, which can be accomplished using hammers manually or using press brakes and similar tools for a more automated approach.

Custom metal fabrication in Philadelphia uses high-end tools and machinery to bend or form the metal into the exact shape desired by their clients with remarkable accuracy.

3. Assembly and Integration

The assembly process involves the systematic integration and assembly of various fabricated metal components, parts, and sub-assemblies to create functional and reliable end products and structures. This intricate process ensures the seamless operation and optimal functionality of diverse metal-based products, machinery, and equipment, meeting the rigorous demands and specifications of modern industrial and commercial applications.

4. Welding and Joining

Welding and joining techniques, including arc welding, MIG welding, TIG welding, and soldering, are fundamental for fusing separate metal parts into cohesive structures and assemblies. These processes provide strong and durable bonds, ensuring the integrity and stability of various metal products, components, and frameworks used in critical applications across industries such as infrastructure development, automotive manufacturing, and industrial machinery production.

The use of advanced technologies, such as robotic welding services, is increasing in this phase. This level of automation not only speeds up the process but also significantly improves the quality and uniformity of the end product.

5. Machining

Metal machining involves using specialized equipment such as lathes, milling machines, and drills to precisely shape, drill, and cut metal components with high precision and accuracy. These machining processes enable the creation of intricate details, fine-tuned features, and complex geometries essential for producing components used in advanced machinery, precision instruments, and high-performance equipment across diverse sectors.

4. Finishing

The last core process in metal fabrication is the finishing stage, where the final touches are added to smooth out any rough edges and add any desired aesthetic finishes. This step could involve sandblasting, painting, or powder coating, depending on the end product’s requirements.
