Compression injection molding: it is an advanced form of traditional injection molding.Advantages: it can increase the flow length ratio of injection molded parts; Adopt less clamping force and injection pressure; Reduce the internal stress of materials; And improve processing productivity.Injection compression molding is applicable to products made of various thermoplastic engineering plastics, such as large-size curved parts, thin-walled parts, miniaturized parts, optical lenses, and parts with good impact resistance requirements.
Low pressure injection molding:Low pressure injection molding process is a packaging process that uses very
low injection pressure to inject hot-melt materials into the mold and solidify rapidly. With the excellent sealing performance and excellent physical and chemical properties of hot-melt materials, it can achieve the effects of insulation, temperature resistance, impact resistance, vibration damping, moisture-proof, waterproof, dustproof and chemical corrosion resistance, and play a good role in protecting electronic components.

At present, the LED industry has always been the focus of attention, it is worthy of LED entrepreneurs to ponder. Recently, LED industry experts released 10 questions on LED competition in the second half of the year, which clarified the future direction of the LED industry. 1. Where is the main battlefield of competition? The development of the LED industry is a gradual process, and it is impossible to explode at a certain point in time. At present, there are two changes in the LED lighting market in China: one is that outdoor lighting is turned to indoor lighting, and the other is that traditional lighting is turning to LED lighting. For the Chinese market, LED lighting products are currently not available in general home applications, mainly in the commercial sector. In addition, our eyes must be directed to sub-segments such as automotive lighting, agricultural greenhouse lighting, and medical lighting. In recent years, from the central to the local, the heat of developing LEDs has not diminished. There are advantages and disadvantages to heat. There are so many people who are concerned about the LED lighting industry is not a bad thing but a good thing. However, as a practitioner in the LED industry, the mind should be calm, consider the problem should be rational, reduce blindness, and increase scientific and rational. The development of the LED industry is a gradual process, and it is impossible to explode at a certain point in time. With the advancement of LED technology, its market scale is expanding, and its application fields are expanding. It has now expanded into sub-sectors such as automobile, agriculture and medical. At present, there are two changes in the development characteristics of China's LED lighting market: one is that outdoor lighting is turned to indoor lighting, and the other is that traditional lighting is turning to LED lighting. For the development of LED lighting, the current growth rate of the LED lighting market has not reached people's expectations, which means that people's expectations for the LED industry are too high, both in the global market and in the Chinese market. The size of the global lighting market is currently only about 120 billion US dollars. China's market size in 2010 reached 300 billion yuan, far lower than people expected. In 2011, the two markets at home and abroad as well as the industrial chain, the middle and lower reaches did not achieve the expected increase. For the Chinese market, LED lighting products are still not available in general household applications, mainly in commercial applications such as industrial, hotel, and shopping malls. For the shopping mall, it is mainly used in the public part, because the shopping mall has high requirements for lighting, involving a series of factors such as color temperature and color rendering. 2. What kind of category will become the main battlefield of competition? In the field of LED lighting applications, LED outdoor lighting, such as LED street lights, is more difficult to promote because of its high power and harsh outdoor working environment, which is currently not suitable for large-scale promotion. Indoor products have low power, the environment is not as harsh as the outdoor, and the temperature changes are not large. Therefore, the initial application of LED lighting should focus on indoor lighting. At present, there are many kinds of LED indoor lighting products, the most important ones are bulb type lamps, reflective lamps, downlights, fluorescent tube lamps, and flat lamps. The Japanese market is dominated by bulb-type lamps, while the European and American markets are dominated by reflective lamps. In addition, the LED has a strong sense of direction when it emits light, so the downlight is also one of the focuses of current applications. These three types of LED lights are worth encouraging and are suitable for the current domestic market and application environment. For fluorescent tube type LED lamps, development is currently not encouraged because of safety problems. If you want to use the flat panel light, the whole luminaire should be replaced, the cost will be higher, but the flat panel light may be one of the future application directions. 3. What is the effect of industry chain competition? At present, LED competition is becoming increasingly cruel. In this regard, I believe that enterprises in the LED era should abandon the competitive mentality of the traditional lighting era, and should use the pattern of competition in the whole industry chain to think about the choice and positioning of enterprises. In order to reduce the risk of business, it will not be ruthlessly eliminated in the big waves. And there are two points that need attention. First, the entire industry chain is from the upstream chip to the midstream package and downstream applications, as well as the supply chain of drive, heat, optics, and cost competition around the market share. The reason is that it is difficult for a single company to influence the cost changes in the system.
