Kunshan thermal conductivity materials and aluminum profiles, can be used in many industries, but the price of the two is not the same, so what are they different?
Although aluminum material as a heat dissipation system technology has been relatively mature, but there are still some shortcomings, the same plastic thermal conductivity material is not without shortcomings, the following is the advantages and disadvantages of the two. The first is the advantages of plastic thermal conductivity materials relative to aluminum:
(1) Light weight in indoor lighting, the weight of the lamp has an impact on many aspects, such as the increase in weight will increase the installation and transportation difficulty of the lamp, and will also cause hidden dangers to personal safety. The density of pure aluminum is 2700kg/m3, the density of aluminum alloy will be greater, and the density of thermal conductive plastic is about 1420 kg/m3, about half of the aluminum alloy, so in the case of the same shape, the weight is only about half of the aluminum alloy.
(2) Safety plastic is an insulating material, and there is no need to worry about security risks caused by the conductive housing of the lamp. In terms of resistance to high pressure testing, plastics have advantages.
(3) Improve design freedom The fluidity of plastic is very good, so it can produce very thin parts, as well as design more complex shapes. The main production method of aluminum shell is die casting or stretch forming, and more complex shapes cannot be processed in the production process. In addition, in terms of apparent effect, injection molding products will be easier to produce, and they can also add their own marks different from other enterprises [2].
(4) convenient processing, higher efficiency Plastic thermal conductivity materials, like other plastic parts, can be formed at one time, without post-processing, and in injection molding, the mold can be designed as one out of four, so the work efficiency is high. Aluminum materials in the extrusion molding often have to remove the burring procedure, if the shape requirements are relatively high, aluminum materials also carry out nickel plating and other processes, the processing cycle will increase.
(5) The starting system is simplified in the case of aluminum alloy, because the shell is conductive, the internal isolation starting system must be used, the plastic itself is insulated, so the non-isolated starting system can be used as a heat dissipation system, because the non-isolated system is not only lower in cost and smaller than the isolation system, it can not only reduce the cost but also take up less space.
(6) Reduce system costs In terms of unit price, the price of thermal conductive plastics per unit mass is necessarily higher than that of aluminum, but the system cost is flat or lower, and the larger the number, the more obvious the cost advantage of plastics. In addition, plastic thermal conductivity materials are currently in an initial stage, and the future price will be reduced with the development of the industry and the increase in product volume, while the price of aluminum as a non-ferrous metal is unlikely to be significantly reduced.
