LED lighting heat dissipation push heat conductive plastic material fin cost 20-30%

The thermal radiation coefficient of the heat-conductive plastic is higher than that of aluminum, and the surface has excellent heat dissipation ability. Although the thermal conductivity of the thermal conductive plastic is inferior to that of the metal, it can be improved by the design of the aluminum member added to the heat dissipating fin, and the heat dissipating fin using the thermal plastic material has a cost advantage over the aluminum.

When I saw an article on the development of thermal fins for LED lighting products, I decided to use the technical energy that I used to work in the high-end engineering plastics field for 25 years to develop thermal plastics that can enter the LED lighting market. After continuous experimentation, more than 3,000 formulas have been developed, first considering the cooling effect of the material, followed by the calculation cost, and then paying attention to the color performance and strength performance of the plastic. At the same time, the thermal conductive plastic is also subjected to the back-mixing experiment to show the recycling. The difference between thermal conductive plastics and new materials is not large, which can effectively reduce the cost of purchasing materials for customers.

The cost advantage of thermal plastics is the best material choice for LED lighting demand

"Cost" is the confidence that thermal plastics are expected to replace aluminum as the biggest factor in the mainstream of heat sink fins. Chen Xunsen does not swear, "We do the material to understand the importance of cost, the product is not good enough to be beautiful, and must meet the cost requirements of customers."

In terms of material cost, the price of thermal plastic sold is about 7-10 US dollars per kilogram, which is 20-30% lower than the cost of aluminum fins. On the other hand, the cost of working hours for customers in processing must also be included. The heat-dissipating fins of aluminum materials must be subjected to surface polishing, smoothing, drilling, and anodizing procedures. In contrast, thermally conductive plastics are formed by injection molding. In this link, the most special is the development of heat-resistant plastic materials that have low wear on the equipment. As a result, the overall cost of the customer system has a definite result.

The raw materials and manufacturing cost of the heat sink fins are the key to the customer's adoption. The heat dissipation performance is also the biggest consideration for the customer. The thermal conductivity of the thermal conductive plastic is not as good as that of the metal, but after the laboratory temperature test, the thermal plastic plastic is used in 8 watts and 10 The temperature of the LED LED bulb is lower than 80 degrees C, which is in line with the general standard of the LED lighting industry. The thermal radiation coefficient of the thermal conductive plastic is much higher than that of the metal, and the thermal energy can be quickly removed from the surface. When the user replaces the bulb, it is not easily burned by the high temperature of the fins, and the safety is better than the consumer.

The customer introduces the attitude of thermal plastics. The injection processing of thermal plastics is different from ordinary plastics. There are many processing techniques. The experience is shared with Reddike. From the experience of Radek, many related knowledge about optical and thermal conductivity is obtained. Completed and successfully introduced applications for LED lighting products such as candle lights, PAR lights, and patio lights. Comprehensive support measures and ample plastic experience are the biggest niche points.

At present, it has been developed with many Chinese customers, and many land factories have a high willingness to use thermal plastics. In the past, LED factories used aluminum as the main raw material for heat sink fins. The trend of using heat-dissipating plastics in the market has just started. The willingness of Taiwanese manufacturers to use heat-conductive plastics is also increasing. However, compared with the mainland manufacturers, Taiwan manufacturers consider the cost of molds. High, the pace of initial adoption is still cautious. Chen Xunsen said that the development cost of molds is about 300,000. Therefore, in addition to providing customers with small purchase and testing services, the company also cooperates with customers to develop molds. To enhance the burden of customer research and development.
