How Are Aluminum Slugs For Electronic Capacitors Made?

Aluminum slugs for electronic capacitors are made of high-quality, corrosion-resistant aluminum alloy.aluminum slugs for electronic capacitors They are characterized by a high formability, low-melting temperature, and moderate hardness (Brinell hardness 23HB). This allows them to be used in a variety of applications. These slugs are shaped into the shells of electronic capacitors using a deep drawing process that involves multiple stamping and trimming steps. This process ensures the aluminum slugs have good mechanical properties and consistent dimensions. They are also subject to a sizing and annealing treatment to enhance their appearance, durability, and reliability. The aluminum slugs are also treated with lubricants to reduce tool wear and improve their stamping performance.

A wide range of slug sizes are available.aluminum slugs for electronic capacitors The largest sizes are suitable for use as the base material for large-diameter extruded products. The smaller sizes are often used in the production of packaging for food, cosmetics, and pharmaceuticals. The slugs are also used in the manufacturing of automotive components and other mechanical parts. They are also often used for the production of sanitaryware.

The slugs are manufactured by melting and casting aluminum. The resulting molten metal is cooled and then formed into various shapes, including a round shape. The slugs are then sent for cold extrusion, where they are transformed into finished products. The slugs are also subjected to a number of surface treatments, such as rolling or shot blasting, to make them suitable for cold extrusion. These surfaces are usually rough, which is necessary to ensure they can be lubricated during the stamping process.

Once the slugs have been formed into the desired shape, they are annealed. This is a crucial step in the production of aluminum products, as it helps to strengthen the material and increase its ductility. They are annealed in a tunnel-type electric furnace at 530degC for about 10 hours, which allows them to achieve the desired properties. The slugs are then cold extruded to produce final products, such as aluminum collapsible tubes, aerosol cans, and aluminum bottles.

In addition to ensuring the quality of the slugs, the manufacturers of aluminum slugs also guarantee that they meet customer specifications. The slugs are tested for a range of properties, including their electrical conductivity and their resistance to fatigue and stress. They are also subjected to a strict inspection and weighing process. This ensures that the slugs are free of defects, such as oil stains, oxidation, and black spots.

After undergoing thorough testing and inspection, the aluminum slugs are packaged for export. They are placed into cardboard boxes, each containing 25kg of slugs. These boxes are then packed onto wooden pallets, each weighing 1125kg. The pallets are then plastic-wrapped for safe transportation to international destinations.

Once the aluminum slugs are ready for shipment, they undergo strict inspection and weighing. They are then placed into a box that is marked with the customer's information, and then placed onto a wooden pallet. The pallets can hold up to 45 boxes and are weighted to ensure that they meet the required shipping specifications.
