Solar Charging Pile

The solar charging pile has completely changed our view on renewable energy and electric vehicle (EV) charging. These innovative charging stations aim to use the energy of the sun to provide convenient and environment-friendly charging methods for electric vehicle owners. A key benefit of the solar charging pile is the ability to generate electricity from solar panels. These panels are mounted on the top of the charging station and can convert sunlight into electricity, which can then be used to charge the electric vehicle. This not only makes the charging process more efficient, but also reduces our dependence on fossil fuels, helping to reduce greenhouse gas emissions. The solar charging pile will generate a lot of heat in the process of energy conversion, and the aluminum heat sink produced by FINE will solve this problem well, improving the energy conversion efficiency and extending the service life of the solar charging pile. In general, the production of solar charging pile is an important step to promote the development of renewable energy and electric vehicles, and the radiator provided by FINE is the core. These innovative charging stations provide a convenient and environment-friendly charging mode for electric vehicle owners, and help reduce our dependence on fossil fuels and cope with climate change.

Blade Battery of CATL

Blade batteries, also known as pouch batteries, are a type of lithium-ion battery that are thin and flexible, resembling a blade or pouch. They have gained popularity in recent years due to their ability to be easily molded into various shapes and sizes, making them well-suited for use in electric vehicles (EVs).FINE, a professional aluminum profile production expert, is a Chinese company established in 2010.They specialize in the production of aluminum heat sinks, aluminum profiles and aluminum deep processed parts.FINE has established partnerships with several major automobile manufacturers, including Tesla and Toyota, the heat dissipation module of blade battery used in Geely Geometry A, BMW iNEXT and other electric vehicles has also been developed. CATL, or Contemporary Amperex Technology Limited, is another leading Chinese company in blade battery development .Founded in 2011, CATL has become one of the largest lithium ion battery manufacturers in the world, providing batteries to many automobile manufacturers, including Toyota, Volkswagen and Tesla.  FINE and CATL have both played an important role in promoting blade battery technology. Due to their flexibility, high energy density and long life, blade batteries may completely change the electric vehicle industry. With the growing demand for electric vehicles, companies such as FINE and CATL are ready, continue to lead the development and production of blade batteries.

Raw Materials of Aluminum Profiles

FINE is an aluminum heat sink manufacturer using high-quality aviation aluminum rods. These rods are used in a variety of applications in the aerospace industry, including aircraft structures, engine components, and airframe components. One of the key advantages of using aviation aluminum rods in these applications is their strength and durability. Aerospace aluminum alloys are designed to withstand extreme conditions encountered in flight, including high temperatures, high stresses, and corrosion. They are also light, which is crucial in the aerospace industry, which focuses on weight reduction. FINE uses a series of alloys to produce aviation aluminum rods. Aluminum rods used in aluminum heat sinks include 6063 and 6061. In addition to using high-quality aviation aluminum rods, FINE is also committed to sustainable development. The company uses recycled aluminum in the production process, reducing the impact of operations on the environment. They also developed a comprehensive recycling plan to ensure that any scrap aluminum is properly treated and reused. Overall, FINE's use of aviation aluminum rods is a key factor in the company's success in the aluminum heat sink industry. They are committed to producing high-quality and durable aluminum heat sinks, while reducing the impact on the environment, which makes them reliable partners for manufacturers around the world.

Moulds of Aluminum Heat Sink

Aluminum profile extrusion is a process used to create complex shapes and cross-sectional profiles from aluminum alloys. The process involves heating a billet of aluminum alloy to a high temperature and forcing it through a shaped opening, or die, to form a continuous profile. An aluminum profile extrusion mould, also known as a die, is a key component in the extrusion process. It is a custom-made tool that is designed to shape the aluminum billet as it is forced through the die. The design of the die determines the final shape and profile of the extruded aluminum. There are two main types of aluminum profile extrusion moulds : open dies and closed dies. Open dies are used to create simple, open-ended profiles, such as round or square tubes. Closed dies, on the other hand, are used to create more complex shapes with internal features, such as channels or grooves. The design of an aluminum profile extrusion mould is a complex process that requires precise engineering and attention to detail. The die must be carefully crafted to ensure that it can withstand the high pressures and temperatures of the extrusion process, while also producing a consistent, high-quality profile.In addition to the design of the die, the material used to construct it is also important. High-quality tool steels, such as H13 or D2, are often used to manufacture aluminum profile extrusion moulds due to their high wear resistance and ability to maintain their shape under high temperatures.


Aluminum Extrusion Heat Sinks

Aluminum extrusion is a process used to create complex shapes and cross-sectional profiles from aluminum alloys. It is a highly versatile manufacturing method that is used in a wide range of industries, including construction, automotive, aerospace, and consumer products. The aluminum extrusion process begins with the creation of a billet, or log, of aluminum alloy. The billet is heated to a high temperature, typically around 700 degrees Celsius, and then placed in a press. A shaped opening, or die, is used to shape the aluminum as it is forced through the press, creating a continuous profile. One of the key advantages of aluminum extrusion is its ability to create complex shapes and profiles with a high degree of precision. The die used in the extrusion process can be custom-made to create almost any shape, including tubes, angles, channels, and more. In addition to its versatility, aluminum extrusion also offers a number of other benefits. It is a cost-effective manufacturing method that allows for the production of large volumes of parts at a low cost. It is also a sustainable manufacturing method, as aluminum is 100% recyclable and can be reused in the extrusion process.

Advantages of FINE CNC Machining

Anodizing is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.

The process is called anodizing because the part to be treated forms the anode electrode of an electrical circuit. Anodizing increases resistance to corrosion and wear, and provides better adhesion for paint primers and glues than bare metal does. Anodic films can also be used for a number of cosmetic effects, either with thick porous coatings that can absorb dyes or with thin transparent coatings that add interference effects to reflected light.

Anodizing is also used to prevent galling of threaded components and to make dielectric films for electrolytic capacitors. Anodic films are most commonly applied to protect aluminium alloys, although processes also exist for titanium, zinc, magnesium, niobium, zirconium, hafnium, and tantalum. Iron or carbon steel metal exfoliates when oxidized under neutral or alkaline microelectrolytic conditions; i.e., the iron oxide (actually ferric hydroxide or hydrated iron oxide, also known as rust) forms by anoxic anodic pits and large cathodic surface, these pits concentrate anions such as sulfate and chloride accelerating the underlying metal to corrosion. Carbon flakes or nodules in iron or steel with high carbon content (high-carbon steel, cast iron) may cause an electrolytic potential and interfere with coating or plating. Ferrous metals are commonly anodized electrolytically in nitric acid or by treatment with red fuming nitric acid to form hard black ferric oxide. This oxide remains conformal even when plated on wire and the wire is bent.
