Inside a Real Metal Fabrication Factory: How Custom Metal Parts Are Manufactured

A true one-stop metal fabrication and manufacturing process does not involve splitting the drawings among multiple factories for production. Instead, it completes all core manufacturing processes, from raw materials to finished products, within the same factory. As a metal fabrication factory with a production area of over 9,000 square meters, we have a comprehensive production system and equipment.

Today, we will take you to the production site to show you, step by step, how a custom metal part is manufactured.

Metal Fabrication Process: Starting With Metal Sheets

In most cases, the production of chassis, brackets, enclosures, and structural components begins with metal sheets.

Laser Cutting: The First Step of Precise Manufacturing

In the production workshop, two 6KW fiber laser cutting machines are operating simultaneously. Whether it’s thin plates, thick stainless steel plates, or complex-shaped parts, they can all be formed in one go through laser cutting. Laser cutting not only ensures dimensional accuracy but also effectively improves material utilization, laying the foundation for subsequent processing. For custom metal parts, this is one of the most important starting points in the entire manufacturing process.

Stamping and Stretching: Achieving High-Efficiency Mass Production

When the order enters the mass production stage, the stamping process will play a crucial role. Our stamping workshop is equipped with:

Stamping is a key process in large-scale metal fabrication factory production.

Bending and Welding: Building Three-Dimensional Structures

After being cut and stamped, the metal materials need to be further shaped into the final structure.

Fine Processing: Drilling, Marking and Structural Optimization

After the product enters the subsequent stage of manufacturing, various auxiliary processes are often required. Equipment in the workshop:

• 12 drilling machines
• 4 laser marking machines

Capable of performing: precise drilling, thread processing, product coding, traceability marking, and brand LOGO engraving. These detailed processing steps ensure that the products can smoothly proceed to the assembly and end-user usage stages.

In-House Casting Capability

Not all parts can be manufactured from sheet materials. For products that bear high loads, impact forces, or have complex internal structures, we will use casting techniques to produce the blanks. The factory has a complete casting production capacity and can produce:

• Carbon steel castings
• Alloy steel castings

After the casting process is completed, the raw materials do not need to be sent out. They can directly proceed to the subsequent CNC precision processing stage. This internal collaborative capability can effectively shorten the production cycle and reduce the difficulty of supply chain management.

CNC Machining for Precision Metal Parts

Whether it is a sheet-metal part or a casting, once it enters the CNC workshop, it undergoes high-precision processing.Our equipment includes:

Through precise tools and stable process control, the processing accuracy can reach ±0.01mm. This is also an important guarantee for many high-precision metal parts to meet assembly requirements.

Surface treatment: Enhancing Product Performance and Appearance

After the mechanical processing is completed, the product will enter the surface treatment stage. All surface treatment processes are carried out within the factory. Common processes include:

Quality Control Across the Manufacturing Process

High-quality products are not achieved through final inspection but are formed gradually throughout the manufacturing process. Therefore, we have established an independent quality control center. The testing equipment includes:
