We have expertise in the manufacturing of both simple and complex extrusion dies, which are accurate and durable to a range of profiles.
The billet preheating process makes our billet precise and the temperature is controlled more precisely to achieve high extrusion consistency which enhances overall performance of a part.
We employ both direct and indirect extrusions, depending on what is the most appropriate to your aluminum profile and design requirements.
Once extruded, parts are cooled and cut to size with high precision to meet your specifications.
Aluminum Extrusion Finishes at Lewei Precision
We provide a range of the finishing types to aluminum extrusions to make them look good, durable, and functional. Finishing solutions that meet the unique requirements of your project are available in any combination of corrosion resistance, professional appearance, and added strength.
Anodized finishes that resist corrosion in various colors, which is suitable where the life and appearance of aluminum parts need to be improved.
Extra strong, durable powder coatings in any color or texture, ideal when a good coating is needed to withstand the outside elements such as extreme wear, corrosion and UV effects.
Electrocoating to increase durability, offer a high level of corrosion resistance and a high quality and smooth surface.
A uniform finish over the parts, with a linear texture that gives a satin effect, which is the best finish to use in both aesthetic and functional purposes.
You require unique finishes that match your specifications and we provide custom finishes that match your specifications in appearance and performance.
It is the perfect finish on steel-related parts; it not only improves the part corrosion resistance but also has a high-quality and professional look.

常见问题
1. What is aluminum extrusion?
Aluminum extrusion is a production process in which heated aluminum is forced through a custom die into producing parts with a specific cross-sectional shape. It is applied to make long aluminum profile in different industries.
2. What is the duration of the extrusion process of aluminum?
It is estimated that the lead time of extrusion of aluminum is 5-7 days when designing prototypes and lower volume production. The bigger production quantities can be more time consuming, based on part and quantity complications.
3. What are the possible materials to be used in aluminum extrusion?
Our extrusion products come in various aluminum alloys comprising of 6061, 6063 and custom alloys. This is because each alloy chosen will depend on the strength, corrosion resistance, and applicability of alloy to your particular application.
4. Is it possible to make custom shapes on the extrusion of aluminum?
Yes, we can make custom profiles of complicated geometry using aluminum extrusion, solid profiles, hollow profiles, or multi-chambered sections. We have the capacity to handle special design requirements according to the project requirements.
5. What industries are capable of utilizing the services of aluminum extrusion?
Automobiles, aerospace, construction, medical equipment, electronics and others are some of the industries where aluminum is used in extrusion. It is employed in the production of structural frames, heat sink and ornamental trims.
6. What are the tolerances of aluminum extrusions?
We have a standard tolerance of aluminum extrusions of ±0.1mm which is very precise on parts. Specific requirements can be tolerated more strictly.
7. What is the advantage of aluminum extrusion over other processes, such as die casting or CNC machining?
Aluminum extrusion is cost effective in high volume production, has better strength to weight ratio and more design capability than die casting and CNC machining, particularly in complex continuous profiles.
8. How do I obtain a quote of my aluminum extrusion project?
In order to receive a quote, you only have to upload your CAD files on our site. We will assess your design and offer you an elaborate design estimate depending on your specifications and needs.
9. Is it possible to change my design once extrusion process has begun?
The design could be changed at the early stages of the project, which might cost some extra money and time. The best thing is to design last and production first so that you can be in time, and at a reasonable cost.
10. What do you do to guarantee the quality of aluminum extrusions?
The high-level inspection procedures such as CMM ( Coordinate Measuring Machines ) are in use to ascertain dimensional accuracy, and a surface finish test and coating validation are in use to ascertain high quality results throughout production.
