The demand for LED dies is in short supply, and the quotation is bullish. Recently, Apple passed the patent of panel sensing technology and used micro LED (Micro LED) to sense the fingerprint on the touch screen. The price of LED has risen in the near future. Lido's frequent transmission of Taiwan's LED stocks has been buying for two consecutive days. Jingdian's 17-day attack rose to 26.45 yuan. The LED chip is in short supply, and the offer is bullish. Recently, Apple passed the patent of panel sensing technology. The micro LED (Micro LED) senses fingerprint recognition on the touch screen, and the price of LED has risen again in the near future. Lido's frequent transmission of Taiwan's LED stocks has been buying for two consecutive days. Jingdian's 17-day attack rose to 26.45 yuan, and the 18th rose more than 6%; Yiguang and Dongbei also surged more than the 17th. 5%, 4%. According to the joint news network, the mainland LED manufacturer Sanan Optoelectronics has taken the lead in raising the price of some products by 8%. The LED industry is expected to enter the price increase cycle driven by rising costs. The rest of the manufacturers said they will wait and see the market to issue the factory and then decide to raise prices. Whether or not. Ye Weifu, chairman of Everlight, said in an interview in January that 2017 LED industry development will be better than 2016, and the growth rate of Yiguang's operation has a chance to see double digits. As lighting products are becoming more popular, related needs and applications will increase, such as Internet of Things (IoT), autonomous driving, automatic vehicle identification systems, and micro LEDs. Regarding the price hike of LED, Ye Weifu believes that some of the representatives are recovering from the boom, and the other part is that lowering the low cost is not good for the manufacturers themselves.

Casting polyurethane prepolymers involves a process where a liquid mixture of polyols and isocyanates is poured into a mold or container and allowed to cure or solidify. This process is commonly used in various industries such as automotive, construction, and manufacturing.
Here is a step-by-step guide on how to cast polyurethane prepolymers:
1. Prepare the mold: Clean the mold thoroughly and ensure it is free from any debris or contaminants. Apply a mold release agent to facilitate the easy removal of the cured polyurethane.
2. Measure and mix the components: Measure the desired amount of polyol and isocyanate components. The specific ratio will depend on the desired properties of the final product, which can be found in the product's technical data sheet. Pour the measured components into a clean mixing container.
3. Mix the components: Use a mechanical mixer or a high-speed drill with a mixing attachment to thoroughly mix the polyol and isocyanate components together. Make sure to mix for the recommended amount of time specified by the manufacturer to ensure complete homogeneity.
4. Degassing: After mixing, it is important to degas the mixture to remove any trapped air bubbles. This can be done by placing the mixture in a vacuum chamber and applying vacuum pressure for a specified period of time. Alternatively, a vacuum degassing unit can be used.
5. Pouring the mixture: Once the mixture is properly degassed, pour it into the prepared mold or container. Take care to avoid introducing any additional air bubbles during the pouring process.
6. Curing: Allow the poured mixture to cure at room temperature or, if necessary, in a temperature-controlled environment. The curing time will vary depending on the specific polyurethane prepolymer used and the desired hardness or flexibility of the final product. Follow the manufacturer's recommendations for curing time and temperature.
7. Demolding: After the polyurethane has fully cured, carefully remove it from the mold or container. Use caution to prevent any damage to the cured part.
8. Post-curing (optional): Depending on the specific polyurethane prepolymer used, post-curing may be required to optimize the material's properties. This can be done by subjecting the cured part to elevated temperatures for a specific period of time.
It is important to note that casting polyurethane prepolymers requires proper safety precautions, such as wearing appropriate personal protective equipment (PPE) and working in a well-ventilated area. Always follow the manufacturer's instructions and guidelines for handling and working with polyurethane prepolymers.
