LED lighting module factory Liqing Technology pointed out that it has successfully entered the Sanli vehicle and obtained the certification of the brand car factory. It is expected to generate operational benefits in the fourth quarter, and the related expansion has been started in response to the order demand of Wuhan Xiaoyan customers. plan. Liqing's consolidated revenue in May was 302 million yuan (NTD, the same below). Due to the May 51 holiday in China, the revenue decreased compared with the previous month, but it still continues to benefit from LED lamp penetration. The increase led to a 30% increase in May revenue compared to the same period last year; the combined revenue for the previous five months was 1.709 billion yuan, an increase of 11% over the same period last year and a record high for the same period in history.
Li Qing said that as the mainland government pays more and more attention to the development of energy-saving and new-energy vehicles, it not only provides a management mechanism for “double points†for each brand car manufacturer, but also gives preferential policies for related subsidies to accelerate the application of new energy concepts in brand vehicles. The R&D technology process such as fuel efficiency improvement, LED lamp features are lightweight, energy-saving and carbon-reducing, high visual visibility and driving safety. It is one of the automotive component products actively introduced by brand car manufacturers.
According to the latest research report of LEDinside, the LED lamp market of China's new energy vehicles will grow at a compound annual growth rate of 54% from 2017, reaching US$95 million in 2022, highlighting LEDs. The huge market opportunities for headlights.
Li Qing stressed that according to the historical revenue performance of the past five years, the first half of the year has been paid for five consecutive years to maintain annual growth, especially in the second half of the year, with the entry into the automotive industry peak season, and currently there are more than seven LEDs in Liqing. The headlight module products continue to be mass-produced and shipped, and we are confident that the revenue performance in the second half of the year will be significantly better than the first half.
Die casting is the pressure of metal molds on a die casting machine and is the most productive casting process. Die-casting machines are divided into two categories: hot-chamber die-casting machines and cold-chamber die-casting machines. The hot chamber die casting machine has a high degree of automation, less material loss, and higher production efficiency than the cold chamber die casting machine. The aluminum alloy die castings that are widely used today can only be produced on cold chamber die casting machines due to their high melting point. The main feature of die casting is that the molten metal fills the cavity under high pressure and high speed, and is formed and solidified under high pressure. The air in the cavity is wrapped inside the casting to form subcutaneous pores, so aluminum alloy die castings should not be heat treated, and zinc alloy die castings should not be sprayed on the surface (but can be painted). Otherwise, the internal pores of the casting will expand due to thermal expansion and cause the casting to deform or bubble when the above-mentioned treatment is performed. In addition, the mechanical cutting allowance of die castings should also be smaller, generally around 0.5mm, which can not only reduce the weight of castings, reduce the amount of cutting to reduce costs, but also avoid penetrating the surface dense layer and exposing subcutaneous pores, causing The workpiece is scrapped.
