Experienced Aluminum Product Processing
In addition to extrusion, CNC, and surface treatment, our industrial park is also equipped with integrated stamping, bending, welding, silk screen, laser engraving and other equipment and production lines to provide our customers with comprehensive custom aluminum fabrication services.
Different from other aluminum processing factories, we have our own industrial park, which basically includes all the processing projects of aluminum custom processing. We do not need to outsource, which reduces production and transportation costs.
Full Services
We provide custom aluminum extrusion profiles and can combine extrusion with other custom processing services for aluminum profiles to create the final part.
Low MOQ Limit
We support sample production and small batch orders for testing purposes. Please contact our team to discuss the specific details of your project.
Fast Delivery
Our own extrusion lines allow us to control production schedules on our own, allowing us to deliver faster than the industry standard.
Finishing Options for Custom Aluminum Profiles
Aluminum parts are usually obtained after multiple processing steps. We are equipped with other equipment and production lines in the industrial park besides extrusion, CNC, and surface treatment. These processing projects mainly include:
- Stamping: The use of a stamping machine and a die to cut or shape metal sheets, usually used to make thin-walled aluminum parts. It is a fast and efficient production method suitable for parts that need to be produced in large quantities.
- Welding: We provide TIG Welding, MIG Welding, Stick Welding, Laser Welding. Please click here to learn more about our welding services and how to weld aluminum.
- Bending:The process of forming aluminum extrusions or thin sheets into specific angles and shapes using mechanical force. Often used to create components with complex geometries.
- Silkscreen: Adding text, graphics, or logos to aluminum surfaces by pressing ink through a screen. This provides a durable decorative effect.
- Laser Engraving: A high-precision process that etches text, patterns, or serial numbers onto aluminum extrusions using a focused laser beam.

Different of Electroplating and Electrophoresis: Which is better?
Among numerous industrial surface treatment methods, electroplating and electrophoresis are often compared because both utilize electric field action to form coatings on conductive workpieces. However, these two processes are completely

Complete Guide to Aluminum Electroplating
Aluminum electroplating is a surface treatment process that deposits a thin metal coating onto Aluminum or Aluminum Alloy parts. The finished products are commonly called Electroplated Aluminum parts. In most

Hard Anodizing vs Regular Anodizing: Key Differences & Uses
When buyers choose a surface treatment for Aluminum parts, one of the most common questions is: Hard Anodizing vs Regular Anodizing — which one is better for my product? The

Does Aluminum Rust?
It is widely understood that iron rusts and copper develops a green patina. This naturally raises the question: Does Aluminum Rust? The answer is not a simple “yes” or “no.”

Zheng Ji Aluminum FAQ
Generally, either laser engraving or silkscreen is used for applying text or patterns. Laser engraving offers high precision and durability, making it ideal for fine details or permanent markings, though it tends to be more expensive. Silkscreen provides vibrant colors and is suitable for large area patterns, with a generally lower cost.
Our die-casting machines are capable of handling a maximum pressure of 400 tons, enabling the production of aluminum parts weighing from a few grams to several kilograms, with dimensions reaching up to approximately 1 meter. By employing advanced die-casting techniques and utilizing high-quality aluminum alloys, we ensure exceptional strength and durability of the components.
The bending process indeed affects the strength of aluminum profiles. During bending, the aluminum alloy undergoes plastic deformation, often increasing strength due to work hardening. However, improper bending angles or parameters can lead to fatigue damage or cracking, reducing strength.
The stamping process is suitable for a variety of aluminum profile products, particularly those that require high efficiency, precise dimensions, complex shapes, and large-scale production, such as intricate components with multiple holes or parts featuring specific edges or recesses. This process enables the rapid manufacturing of lightweight aluminum parts while meeting stringent.
