A die-cast heat sink is a type of heat sink manufactured using the die-casting process and is widely used in the electronics, telecommunications and computer industries. Its main function is to help electronic equipment in high load work effectively heat dissipation, to ensure stable operation of the equipment. Compared with the traditional casting process, the die-casting process has higher precision and better heat dissipation performance, so it has become an important choice in the manufacture of modern heat sinks.What Is Die Casting?Die casting is a metal casting method in which molten metal is injected into a metal mold under high pressure and cooled to form the desired shape. The process is applicable to light metal alloys such as aluminum, zinc, and copper, and has the advantages of high productivity, high precision, and smooth surfaces. Die casting is usually used in the production of high-precision parts, such as automotive parts, electronic product shells, heat sinks and so on.The Production Process of Die-casting Heat SinkMold design and manufacture: first of all, designers according to the specific requirements of the heat sink, design the corresponding mold. The design accuracy of the mold determines the quality and performance of the heat sink.Molten metal injection: choose suitable metal material (such as aluminum alloy), heat it to molten state, and then inject the molten metal into the mold through die-casting machine.Cooling and demolding: After the metal is injected, it is rapidly cooled in the mold to form the desired shape of the heat sink. The cooling time is short and the production efficiency is high.Post-treatment: The cooled heat sink usually needs to go through deburring, surface treatment and other processes to ensure its quality and appearance. Advantages of Die-casting Heat Sink1.

In the design and manufacturing process of electronic products, heat dissipation has always been a core issue that designers and engineers need to focus on. With the continuous development of processors, graphics cards and other high-performance chips, how to effectively dissipate heat to prevent equipment overheating has become an important determinant of performance and life. In this process, Thermal Interface Material (TIM) plays a crucial role.Thermal Interface Material (TIM) is a material used between two heat sources, which is mainly used to enhance the heat transfer efficiency and reduce the thermal resistance between the heat source and the heat sink. Typically, in microelectronic devices, the contact surface between the chip and the heat sink usually has irregularities or tiny voids, which can significantly increase the thermal resistance and reduce the heat transfer efficiency. Therefore, thermal interface materials are used in electronic devices between processors, graphics cards and heat sinks, etc., to fill the tiny gaps between the two and ensure that heat can be efficiently conducted from the electronic components to the heat sink device.The Importance of Thermal Interface MaterialsIn modern high-performance electronic devices, thermal management is a key factor in maintaining system stability and extending service life. If heat dissipation is poor, excessive temperatures can lead to:-Performance degradation: Overheating can lead to downclocking or protective shutdown of core components such as the processor, seriously affecting the performance of the device.-Hardware damage: Long-term excessive temperature will accelerate the aging of hardware, and even cause irreparable damage.-Decrease system stability: An environment with large temperature fluctuations will lead to system instability, even leading to blue screen of death, lagging and other phenomena.Thermal Interface Material (TIM) can effectively reduce these risks, enhance the cooling efficiency of the device, and ensure that the device can still maintain good performance under high load for a long time. By choosing the right TIM, you can not only improve the thermal performance, but also reduce energy consumption, minimize noise, and extend the service life of your hardware.Types and Benefits of Thermal Interface MaterialsThere are many types of thermal interface materials, the following types are common, each with different characteristics and advantages.1. Thermal Paste (Thermal Grease)Thermal Paste is one of the most common thermal interface materials and is widely used between processors and heat sinks. It consists of components such as metal oxides and silicone-based oils, which are able to fill in the tiny voids on the contact surfaces, thus increasing the efficiency of heat transfer.Advantages: Thermal paste has high thermal conductivity and is suitable for most computer hardware. Easy to use and cost-effective.Disadvantages: After a long time of use, the thermal paste may dry up, resulting in a decrease in thermal conductivity.2. Thermal PadThermal pad is a solid material of uniform thickness, usually composed of silicon, polymers and fillers. It is commonly used between heat sinks and electronic components, especially where large areas need to be covered.Advantages: Easy to install, no need to apply; suitable for automated production lines. Compared to thermal paste, thermal pads are more stable and less likely to dry out.Disadvantages: Thermal conductivity is usually inferior to thermal paste.3. Heat PipesHeat Pipes are a common heat sink component. Although it is not a thermal interface material in the traditional sense, heat pipes are used with epoxy resins in some efficient thermal solutions to enhance heat transfer efficiency.Advantages:  High thermal conductivity, suitable for high power dissipation needs.Disadvantages: Higher price, complicated installation.4. Thermal AdhesiveThermal Adhesive is a solid state glue, commonly used in those occasions that do not require frequent disassembly. Its main advantage is that it can provide strong adhesive force to fix the radiator.Advantages: Strong adhesion to hold the heat sink in place.Disadvantage: Once applied, it is difficult to remove, and the scope of application is limited.5. Graphite SheetsGraphite Sheets are a flexible material with good thermal conductivity, and are commonly used in consumer electronics such as cell phones and tablets.Advantages: Good thermal conductivity, flexible, and suitable for large-area contact.Disadvantages: Slightly less thermally conductive compared to thermal paste.How to choose a thermal interface material?There are several factors to consider when choosing the right thermal interface material, including the device's heat dissipation needs, the environment in which it will be used, the material's performance and cost. Below are some key recommendations for selecting a thermal interface material:1. Thermal ConductivityDifferent types of thermal interface materials vary greatly in thermal conductivity. Generally, thermal paste has superior thermal conductivity and is suitable for high performance electronic devices. For general consumer electronics, thermal pads or graphite sheets may be sufficient.2. Application ScenariosWhen choosing a thermal interface material, it is very important to consider the environment in which the device will be used. If the device needs to run in a high-temperature environment for a long period of time, it is recommended to choose a material with excellent thermal conductivity and strong stability, such as high-end thermal paste or thermal conduit. For devices that are not often disassembled, thermally conductive adhesive can provide better fixation.3. Cost-effectivenessDifferent types of thermal interface materials vary greatly in price. For products with limited budget, thermal pads or thermal paste is a cost-effective option, while for high-end hardware, investing in some high-performance thermal materials, such as high thermal conductivity thermal paste or graphite flakes, can ensure the stable operation of the device for a long time.4. Ease of InstallationThermally conductive paste needs to be applied carefully, and is prone to uneven coverage due to improper handling. Thermal pads, on the other hand, are much easier to install and are suitable for mass production and automated production lines. Choosing the material that suits the needs of your production line can improve production efficiency.5. Environment and temperatureThe temperature resistance of different materials also varies greatly, especially in some industrial-grade applications, the selection of materials needs to consider the stability of the material in a high-temperature environment. Typically, high-quality thermal paste or thermal pads can withstand higher temperatures, while thermal adhesives may fail at high temperatures.Thermal interface materials play a critical role in the cooling system of electronic devices. the right choice of materials can significantly improve the thermal performance of the device, extend its service life and improve system stability. lori's thermal solutions will help you select the right thermal interface material based on a number of factors, including application scenarios, thermal conductivity requirements, cost budget and other factors, to effectively improve the overall performance of the device. In the future, as electronic technology continues to advance, thermal interface material technology will also continue to evolve, and Lori will provide more efficient and intelligent thermal solutions.

Hard anodizing is a more complex and advanced surface treatment process than anodizing, which is often applied in the production of aluminum heat sinks. Although hard anodizing and anodizing are similar in name, they have significant differences in process, characteristics and application areas.Thickness and Hardness DifferenceThe film thickness of hard anodizing is generally 40-100 microns, while the film thickness of ordinary anodizing is usually 15-25 microns, which gives hard anodizing a significant advantage in wear resistance and corrosion resistance. In terms of hardness, the hardness of hard anodizing generally reaches HV300-500, while ordinary anodizing is HV200-300, hard anodizing has higher hardness.Difference In Process ConditionsTemperature conditions:The temperature of hard anodizing is generally below 5 degrees Celsius, while the temperature of ordinary anodizing is usually 18-22 degrees Celsius, sometimes up to 30 degrees Celsius.Voltage and current: Hard anodizing adopts step-by-step increasing voltage, up to more than 100 volts, while ordinary anodizing adopts constant voltage. In addition, hard anodizing has a higher current density, usually 1.5-3A/dm², while ordinary anodizing is 1-1.5A/dm².                Lori Hard Anodized Heat Sink                Lori Yellow Anodized Heat SinkAppearance DifferencesThe oxide film of anodic oxidation is thinner, the color is lighter grey, and it can be tinted with multiple colors after post-treatment process to increase the aesthetics. Hard anode anodizing has a thicker oxide film, darker grey or black in color, and is usually not suitable for decorative purposes, but is more focused on functionality.Differences in Application AreasBecause hard anodizing has higher abrasion and corrosion resistance, it is particularly suitable for applications that require a high degree of protection, such as aerospace, automotive and precision instrumentation. Ordinary anodic oxidation is widely used in the surface treatment of general metal products, such as aluminum furniture, architectural decorative materials, etc., which is lower cost and can meet the basic protection and decoration needs. Anodizing and hard anodizing are two very important surface treatment technologies, each with unique advantages and application areas. Anodizing is more decorative and mildly corrosion resistant, while hard anodizing focuses on providing high hardness, high abrasion resistance, and greater corrosion resistance. Whether anodizing or hard anodizing, Lori can take a look at the longevity and functionality of aluminum radiators with different surface treatments based on an assessment of the thermal environment.

High-power lasers (fiber lasers, YAG lasers, CO2 lasers, etc.) are widely used in industrial applications such as laser cutting, welding, engraving, marking and other fields. Due to the high power and precision requirements of lasers in these applications, lasers generate a lot of heat during operation and must be cooled by an effective cooling system to ensure their stability and long-term reliability. Here are a few key reasons why high power lasers require a cooling system:1. The High Power Output of the Laser Generates A Lot of HeatHigh power lasers convert electrical energy into laser energy, but this process is not entirely high efficient. Most of the electrical energy input is converted into heat, which tends to build up inside the laser if not dissipated in a timely manner. Excessive heat will not only affect the performance of the laser, but may also lead to damage to the equipment and even affect the quality and stability of the laser beam.2. Preventing Performance Degradation Due to Temperature FluctuationsThe output power, beam quality and stability of a laser are all closely related to its operating temperature. High temperatures can cause deformation of the laser's optics, which can affect the focus, directionality and quality of the laser beam. Temperature fluctuations can also lead to wavelength drift or power output instability of the laser, which can affect processing accuracy and results. Therefore, maintaining a stable temperature is critical to the continued efficient operation of the laser.3. Extend Laser LifeWorking in a high temperature environment accelerates the aging and wear and tear of the laser's internal components, especially the optical components and circuitry. Overheating can cause these critical components to deteriorate or even fail, shortening the life of the laser. With an efficient cooling system, the laser's operating temperature can be controlled within the ideal range, slowing down the aging process of the components, extending the service life of the equipment and reducing the frequency of maintenance.4. Enhancement of Laser Working EfficiencyThe cooling system not only helps the laser to maintain a stable working temperature, but also ensures that the laser continues to output high power under high load for a long period of time. When the laser is in the right temperature range, it can operate at high efficiency and maintain low energy consumption and heat loss. Effective cooling also improves overall productivity by preventing breakdowns and downtime caused by overheating. 5. Reducing Equipment Damage from OverheatingLasers and their critical components, such as the laser gain medium and electrical parts, are susceptible to overheating in high-temperature environments. If heat is not dissipated in a timely manner, these components may malfunction or burn out, resulting in laser downtime or permanent damage. The cooling system can effectively take away the heat generated to ensure that the equipment will not be damaged due to overheating, to protect the long-term operation of the equipment.6. Ensure Laser Stability and SafetyHigh-power lasers in industrial applications are often in harsh working environments and must withstand long periods of high load operation. In this process, if there is no effective cooling, the laser temperature may rise rapidly, leading to system instability or even out of control. The cooling system ensures that the temperature is always kept within a safe range, thus avoiding safety problems caused by overheating and ensuring that the laser process is precise and controllable.7. Economy of High Efficiency Cooling SystemAlthough an efficient cooling system requires some investment, it reduces the costs associated with equipment failure, downtime and maintenance. Cooling systems help companies save significant operating costs by extending the life of the laser, increasing productivity, and reducing unnecessary maintenance. At the same time, liquid cooling systems are typically more energy efficient than air cooling, improving energy efficiency and reducing overall energy consumption.8. Accommodating High Loads and High Power ApplicationsIn industrial applications such as laser cutting, welding and marking, lasers often operate under high load and high power conditions. Lasers need to maintain efficient and stable performance under these extreme conditions. In this case, only through a strong cooling system can ensure that the laser's temperature is within acceptable limits and prevent performance degradation or damage caused by overheating. High-power lasers require cooling systems for a variety of reasons. A cooling system not only dissipates heat effectively and maintains a stable working temperature of the laser, but also extends the life of the equipment, improves efficiency, reduces maintenance costs, and ensures that the laser continues to operate stably under high load. Whether in laser cutting, welding or other high-precision industrial applications, Lori's laser liquid cooling modular cooling systems are an important safeguard for laser performance and safety.
