  According to reports, the global temperature will rise to 60°C in 2030. Ordinary plastics are still treated by incineration and cremation, causing a large amount of greenhouse gases to be discharged into the air. Items made from Styrofoam and plastic wind up in landfills by the ton every year. These products take centuries to degrade and when they do, they can leave toxic residue behind. Food service enterprises were once notorious for producing much of that non-biodegradable waste. In recent years, many in the food service industry have switched to biodegradable products made from vegetable matter like corn and sugar cane. Since they are made with naturally-occurring materials, these products break down easily in the soil. while polylactic acid plastics are buried in the soil to degrade and produce The carbon dioxide directly enters the soil organic matter or is absorbed by plants, will not be discharged into the air, and will not cause the greenhouse effect. What is the 1...

With the popularity of the Internet, the development of mobile terminals. The emergence of smart phones allows everyone to operate everything with a single phone. People are becoming increasingly dependent on mobile phones. Think of how much time we spend with mobile phones every day, and the state of not leaving the hand must be a portrait of many people. But have you ever wondered how many bacteria there are in a mobile phone that can't be separated? It may become a huge hidden danger to our health. The bacterial content on the surface of the mobile phone is as high as 120,000 / c㎡, which is 18 times the bacterial content of the toilet handle. Various germs and viruses are hidden in it。 First let's take a look at our most commonly used disinfection method-alcohol alcohol disinfection. Can it really disinfect? The main component of alcohol is ethanol. Too high concentration of alcohol will form a protective film on the surface of the bacteria, preventing alcohol from ...

In October last year, Apple launched the third-generation TWS (True Wireless Stereo) headset, AirPods Pro, on the official website for $ 249. This price is higher than the previous two generations, but it has not hit consumer enthusiasm in the slightest. Earlier, the two generations of TWS headphones released by Apple reversed the decline in sales after the release of ordinary electronic products, and became absolute benchmarks for the TWS headphones industry. The TWS headset is not just a sound transmission tool. Its more important role is an AI assistant based on voice interaction technology. As a smart wearable device, the TWS headset is designed to provide a better human-machine interaction experience. For consumers of TWS headsets, the instant automatic connection can be achieved after the initial setting, so a smooth user experience is more important than sound quality. This can also provide some explanation for "why AirPods can produce word-of-mouth effect...

3.IML technology The outstanding features of in-mold insertinjection molding (IML) technology are: the surface is a hardened transparent film, the middle is a printed pattern layer, and the back is a plastic layer. Because the ink is sandwiched between, the product can prevent the surface from being scratched and resistant. It can rub and keep the color vivid for a long time. IML technology production process: IMLtechnolog y product effect: 1）   Diversification of printing appearance effects: By combining soft-touch transfer printing with printing technologies such as color and electroplating, various appearances can be realized. 2 ） The research and development of ultra-thin IML, the thinnest can reach 0.80mm, and the deformation is less than 0.5mm; the deformation of 6-inch battery cover is less than 1.0mm; the thickness of local glue reduction can be 0.6mm. development trend: In the existing equipment and process flow of IML technolog...

The 5G era is approaching. Mobile phone shell material from plastic to metal and non-metal material cycle, plastic because of the low cost, favored by the low-end market The evolution from the IML to the IMT process has made plastics more useful , which can approach the 3D optical texture of the simulated glass back cover, and has become the choice of many CMF designers. LDS has been widely used in plastic rear case antennas in the 4G era, but whether it can be adapted to the high-end curved glass 3D back cover of the 5G era needs to continue to be developed. IMT technology can be further extended to IME technology, which integrates electrical and decorative functions and is applied to the intelligent surface of future cars. Injection molded transparent PC back cover, as a lower cost and more efficient product form, with better impact strength and durability, is attracting more and more attention from traditional plastic factories. 1.LDS technology The principle of LDS techno...

The structure of the hot runner mold is generally the same as that of the thin nozzle. The biggest difference is that the runner is located in one or more hot runner plates and hot nozzles with constant temperature. There is no cold material demoulding, the runner and gate are directly on the product. Therefore, the runner does not need to be demolded. This system is also known as the nozzleless system, which can save raw materials. It is suitable for the product that the raw materials are expensive and the product requirements are high. Hot runner system, also known as hot sprue system, is mainly composed of hot runner sleeve, hot runner plate and temperature control electric box. There are two types of hot runner system: single point hot sprue and multi-point hot sprue. Single-point hot sprue is to use a single hot sprue sleeve to inject molten plastic into the cavity directly. It is suitable for plastic molds with single-cavity and single-gate; multi-point hot-gate ...
