4.Surface and edge quality
Slight scores, spallings or discolourations result from the manufacturing process. Scratches, scour
marks, indentations and other damage due to mechanical action cannot always be avoided.
An assessment of whether such defects are acceptable shall be based on the following:
- Large scores, spallings, cracks and damaged areas, incomplete slugs, flaking, formation of blisters and inclusions of foreign matter are not permitted. Slight damage due to production process, such as edge deformations, are unavoidable and hence is permitted.
- Slight scores, indentations and edge deformations, and discolourations due to a heat treatment or surface treatment, such as scouring or blasting, are unavoidable and hence are permitted.
5.Surface treatment
Surface treatment directly affects the appearance and performance of Aluminum Slug in processes like stamping and deep drawing. We offer a variety of surface treatments, primarily categorized into bright and roughened finishes.
After roughening, the aim is to improve the lubrication properties for better stamping efficiency. We provide coated, blasted, and tumbled surface treatments to meet the surface quality requirements of different industries.
The choice of surface treatment should take into account the final product's aesthetics, durability, and ease of subsequent processing.

FAQ
How is the aluminum electronic capacitor shell stamped?
1050 aluminum slugs are formed into electronic capacitor shells using a deep drawing process, which involves multiple stamping, trimming, and annealing steps.
The deep drawing process shapes the aluminum slugs into the desired shell, while the annealing treatment ensures good formability and mechanical properties.
Additionally, lubricants are used to reduce tool wear and ensure the products have smooth surface quality and consistent dimensions.
How is the aluminum collapsible tube stamped?
Aluminum Collapsible Tubes are typically manufactured using punched aluminum slugs through a combination of deep drawing and cold extrusion processes. In the production process, 1050 aluminum slugs are first subjected to precise stamping by a high-precision press, and then undergo multiple deep drawing operations to gradually extend the slug into a tube shape.
Lubricants are generally used during the stamping process to ensure smooth extrusion without tearing, followed by annealing treatment to enhance formability.
Can 1050 aluminum slug be used for stamping whole aluminum bottles?
Yes, due to the excellent machinability and deep drawing performance of 1050 aluminum slugs, they are well-suited for manufacturing whole aluminum bottles (such as cosmetic bottles, pharmaceutical bottles, and aerosol cans).
These aluminum bottles are typically formed through deep drawing and cold extrusion processes. The superior quality of the aluminum slugs ensures the final products are uniform and of high quality.
