Aluminum heat sinks are widely used don all kinds of electrical appliances and automobiles. Typical steps to make qualified aluminum heat sinks: precisely extrude the profiles(the extrusion conductivity need to be very good), cut to length, milling the bottom of base of fins to get perfect flatness(so that the bottom of heat sink can touch well with the unit in need of heat dissipating), drilling or milling some holes (for assembling the heat sink with the unit to be dissipated, usually screws are used), anodizing. Aluminum heat sinks are widely used in various electrical appliances and automobiles due to their excellent thermal conductivity and lightweight properties. They play a vital role in dissipating the heat generated by electronic components and ensure efficient and reliable operation of the equipment.

Anodizing is an electrochemical process that transforms the surface of aluminum profiles into a decorative, durable and corrosion-resistant surface. The process involves immersing the aluminum profile in an electrolyte solution and passing an electric current through it. This forms an oxide layer on the surface of the aluminum, which can then be dyed to achieve a variety of colors and finishes.To begin anodizing operations on aluminum extrusions, the first step is to prepare the surface by thoroughly cleaning and degreasing it. Any contaminants on the surface will interfere with the anodizing process, so it is critical to ensure that the aluminum extrusion is free of dirt, oil and other impurities.After the surface treatment is completed, the aluminum profile is immersed in an electrolyte, usually containing sulfuric acid or alkali. A direct current is passed through the electrolyte, causing an oxidation reaction on the aluminum surface. This forms a layer of aluminum oxide, which is an integral part of the metal and has the desired decorative and protective properties.

When it comes to machined aluminum parts, ensuring that the threads meet the required specifications is critical to the overall functionality and performance of the final product. One of the most effective ways to check if the threads on a machined aluminum part meet the requirements is to use a go and no-go gauge. Go and no-go gauges are used to ensure that threads are machined to the correct size and pitch, while no-go gauges are used to verify that threads do not exceed the maximum allowable size and pitch. To begin checking the threads on a machined aluminum component, first apply a go gauge to the threaded portion. If the go gauge fits smoothly and completely into the thread, the threads meet the minimum requirements and are within acceptable tolerances. On the other hand, if a stop gauge is used and fits into the thread, the threads exceed the maximum allowable size and pitch and therefore do not meet the requirements.

Twist inspection of aluminium extrusions are very necessary to make sure the extrusion can be fixed with other parts perfectly without failure of its function,especially for long extrusions. Firstly, we prepare a standard platform (please refer to the platform in the video), then put the article to be checked onto it, and use requested plug gauge (the thickness of the plug gauge can be 0.1mm , 0.2mm,0.3mm, 0.4mm,0.5mm, 0.6mm,0.7mm, 0.8mm, 0.9mm,1.0mm etc). If the gap between the extrusion and platform are out of tolerance, it has to be scrapped.

Aluminum tubes are widely used in various industries due to their lightweight, durable and corrosion-resistant properties. However, in order to enhance the appearance and provide a smooth, polished surface, it is often necessary to brush the surface of aluminum tubes. Brushing the surface not only improves the aesthetics, but also helps to remove any blemishes or stains, giving a high-quality, professional appearance. In this article, we will discuss the process of brushing the surface of aluminum tubes to achieve a smooth and even surface. Usually the hemp rollers are used to brush the tubes. Different grains on the hemp rollers create different density of brush or roughness. Brushing operation needs very skilled workers to obtain best effect. 

A very important process in the production of self-walking luggage frames is the deburring of the aluminum frame. Deburring is the process of removing sharp edges and burrs from the metal surface, which plays a vital role in ensuring the quality and safety of the luggage frame. When deburring is done properly, the assembly of the luggage body will become easier and more efficient and the safety. Deburring aluminum frames for self-propelled luggage requires the use of specialized tools and techniques to smooth the edges and remove any burrs that may be present. This not only enhances the aesthetics of the frames, but also ensures that they can be handled safely during the assembly process.

CNC milling machines are ideal for handling precision milling and drilling tasks in aluminum extrusions. Equipped with advanced technology and high-precision fixtures. Aluminum extrusions are used in a variety of industries including aerospace, automotive, and construction due to their excellent strength-to-weight ratio and corrosion resistance. CNC milling machines play a vital role in shaping and refining aluminum extrusions to meet the specific requirements of different applications. In addition, CNC milling machines are able to process large volumes of aluminum extrusions with consistent quality. This is particularly important for industries that need to mass-produce parts, as the machines can run continuously with minimal human intervention, increasing productivity and cost-effectiveness.
