At present, the die casting industry mainly die casts aluminum alloy, zinc alloy and magnesium alloy, as well as a small amount of copper alloy and other metal die casting parts. Since die-casting uses molds to form, a relatively long mold manufacturing cycle is required in the early stage, and the production efficiency is high after the mold is manufactured. Therefore, for die casting products, it is especially suitable for mass production, with relatively low cost and high efficiency. However, since the die-casting material is a metal material, it is more difficult to demould compared with the plastic material, so a relatively large demolding slope needs to be used, and the shrinkage of the metal itself causes the precision not to be very high. For positions that require precision assembly, subsequent secondary CNC machining is usually required to achieve the accuracy requirements. Die casting parts can be seen everywhere in industries such as automobiles, lighting, machinery, communications, electronics, and home appliances. Some die-casting products as shown below:

The price of LED bulbs fluctuated slightly in June, and the Chinese market experienced a significant decline.
According to LEDInside's latest LED bulb retail price survey conducted by research firm TrendForce, the average retail price of LED bulbs replacing 40W worldwide in June this year (June 2014) increased by about 0.9 micro-liters to $14.4. Among them, the price drop in the US is more obvious. The global average price of replacing 60W LED bulbs dropped by 0.6 to reach US$ 19.4. LEDinside observed that in the first quarter of China, the price of some of the products replacing 40W and 60W was more obvious, and the overall quarterly decline was 19.7 and 9.8 respectively. Mainly due to the rapid reduction of local brand commodity prices, such as Foshan Lighting, Hyde Lighting, etc. Both continue to lower the price of the product. In addition, some high-priced items of international brands temporarily withdrew from the market due to the adjustment of sales, which also contributed to the decline in average prices. At present, the overall price of the Chinese region is the lowest in all major regions of the world. LEDinside believes that there is still a significant difference between local brands and international brands in the Chinese LED bulb market. Different from the low-cost strategy adopted by international manufacturers in the United States and Europe, the price of brand bulbs such as Philips and Osram in China is still far above average. In addition, due to the weakness of cost and resources, international brands are currently more difficult to compete with Chinese brands in terms of price. The low-priced products of local brands are weak in overall brand image and product performance, which also leads to the rapid increase in consumer acceptance and reliability. Therefore, the growth rate of the LED bulb market penetration rate and the price decline rate can not match. The price movements in different regions were mixed, and the global average price fluctuated slightly. The average price of commodities replacing 40W in the US region showed a large decline in 5.3 in June. The price of some original products has dropped sharply during the promotion period. For example, GE's 9W bulbs have dropped by 30 in June. In addition, Philips' 8W dimmable bulbs have also been lowered this month. The average price of light bulbs replacing 40W in other regions has not been lowered significantly this month. In place of the 60W commodity segment, the price of the German region fell sharply in 25.4 in June. The prices of original commodities have basically stabilized or declined, and some commodity prices have been lowered significantly. For example, the price of LG12.8W bulbs has been lowered from US$14.8 to US$7.9. In addition, some of the original high-priced goods temporarily withdrew from the market. For example, some of the bulbs sold in OSRAM for more than $30 were discontinued this month. In Japan, the price in June showed a large increase of 9 to reach 18.3 US dollars. The price of the original commodity fluctuated, and some low-priced items were temporarily discontinued. For example, the KEIAN12W880LM bulb was sold for about $13.8. In addition, exchange rate changes have also led to an increase in average prices.
