Prevent die-casting of mould damage

 

　　1. Good casting structure design

　　The wall thickness of the casting is as uniform as possible, Die casting so as to reduce heat fatigue caused by local heat concentration. The corners of the casting should be properly cast round corners to avoid the stress caused by the sharp corners on the die.

　　2. Reasonable design of die structure

　　1) the components shall have sufficient stiffness and strength to withstand pressure without deformation. The wall thickness should be sufficient to reduce deformation.

　　2) design of pouring system to minimize the impact and erosion of the core.

　　3) select the tolerance and surface roughness of each component correctly.

　　4) keep the heat balance of the mould.

　　3. Standardize heat treatment process

　　The metallographic structure of the material can be changed by heat treatment to ensure the necessary strength, hardness, stability of the dimension under high temperature, Multi slider die casting machine thermal fatigue resistance and material cutting performance.

　　The correct heat treatment process will get the best mold performance, die casting machine while the steel performance is controlled by quenching temperature and time, cooling speed and tempering temperature.

　　4. Control of casting process

　　1) temperature control: preheating temperature and working temperature of mould; zinc die casting The casting temperature of the alloy is in a low casting temperature.

　　2) reasonable die-casting process: ratio pressure and filling speed.

　　3) adjust the clamping force of the machine, so that the die force is even. Pay attention to cleaning the debris on the surface of the mold, so as to avoid the uneven surface force of the mould.

　　4) strictly control the alloy smelting and reduce the gas in the metal liquid.

　　5. Maintenance and maintenance of mould

　　1) regularly eliminate stress

　　2) mould repair

Vulcanization process of rubber products

 

　　Early on, the main purpose of natural rubber was to make erasers. It was later used to make small rubber tubes. It wasn't until 1823 that the British chemist, Rubber O-Ring mackintosh, invented the rubber to dissolve in coal tar and then coated it with a tarp to make raincoats and rain boots. However, the raincoat and rain boots melt in summer and become hard and crisp in winter. To overcome this shortcoming, Rubber Parts many people were trying to find a way out.

　　American invention, Charles Goodyear rubber modification experiment was carried out, he put the natural rubber and sulfur on heating together, hoping to get a at all temperatures keep dry all year round and elastic material. He didn't succeed until February 1839. One day he mixed the rubber, sulfur, Rubber Gasket and turpentine into the pot (the sulfur was only for dyeing), and the mixture in the pot spilled over the hot stove. To his surprise, the mixture didn't melt after it fell into the fire, but it was burned as it was, Rubber Seal and the remaining unburned mixture in the furnace was elastic. He peeled the splash off the stove and found that he had prepared the elastic rubber he wanted. After continuous improvement, he finally invented the rubber vulcanization technology in 1844.

　　Vulcanization is the last process in the production of rubber products. Vulcanization is the crosslinking process of rubber macromolecule from linear structure to reticular structure under certain conditions. The vulcanization method is cold vulcanization, Custom Mold Rubber Parts room temperature vulcanization and hot vulcanization. Most rubber products use hot vulcanization. The heat-vulcanized equipment has vulcanized canister, plate vulcanizing machine etc.

How to select and deploy digital signage player

 

　　Digital signage Player is different from PC's software Player, such as: Windows Media Player and Real Player. It is an external hardware that can support and transmit digital signage system content, sunlight readable widely used in Banks, hotels, restaurants, shopping malls, hospitals, retail stores, outdoor billboards, etc.

　　The digital signage player is equipped with a high-end video card. The player seems simple, but the interior is very different. For example, panel PC some are based on Linux, some are based on XP or Microsoft embedded systems. These players are different from the one that is used to replace the disc player. The single-player player needs a built-in fan and is used in a ventilated place. As a result, All in one computer those industries that have low requirements for system stability and those that do not need mobile devices usually adopt single-player players.

　　How do we deploy digital message systems? How do we do that? "First of all, should understand that your players need to realize what function, and with continuous development of technology, so you have to consider that many players still can use the function in the years to come. Secondly, end users need to understand the development of the industry and understand the development direction of future applications. In this way, this technology investment will be used for a longer period of time."

　　The player function has simple, low price, also has the function complex, the price is high, but only through good union can play the content that the audience is interested.

　　In the deployment of digital signage system, select the players play content aspect, at present, many customers did not actually through the network to connect to the player, just by players play some repetitive content, but if the content of the need to play more, just need to choose more players and spend more money.

The future demand for digital signage will accelerate growth

 

　　Digital signage can play digital images, messages, or advertisements at one or more locations simultaneously. By being able to play multiple blocks simultaneously in the same image, media content will be able to be broadcast in a more intelligent way. For example, Industrial monitor specific content and activity messages are broadcast to a particular audience at a specific location.

　　Many broadcast devices are now used in digital signage, such as plasma televisions, Box PC LCD displays, CRT displays, LED displays, and digital signage machines. In terms of future development trends, the use of LCD screens in digital signage is the largest and future mainstream product.

　　Is outstanding in the field, IP66 should belong to the digital sign advertising content of Chinese enterprises' Focus Media (Focus Media), Focus Media in July 2005, listed in nasdaq, share price increase of 297, p/e ratio of about 40 times, caused a digital sign a whirlwind, obvious market expectations for digital signage industry vision.

　　And digital signage applications more as a panel industry embedded application to Taiwan emerging opportunities, Taiwan China digital signage industry leading companies, such as research, touch screen monitor such as melting process for digital signage was launched the overall Solution (Total Solution) and create the revenue growth.

　　According to iSuppli, a leading research firm, the global digital signage market will grow at a rate of 30 per year between 2005 and 2010, gradually replacing traditional advertising with thin screens. Using stores digital signage can stimulate the promotion of new product sales growth 30 to 300, also can let turnover increased 30, and make consumers reduce the waiting time for about 15, let consumers can more quickly find the required items.

　　Market is bullish on the application of digital platform became popular, digital signage demand will accelerate the growth of the future, as the market is vast, and belongs to the customization features a variety of products, expectations will be the fastest growing after TV entertainment and personal computer's third-largest LCD product applications.

Digital signs have become the third largest market for liquid crystal displays

 

　　Digital signage is a kind of new media concept, refers to the shopping malls, supermarkets, hotel lobby, restaurants, cinemas and other public places, Industrial pc which is full of people through the large screen display equipment, distribution business, financial and entertainment information professional multimedia audio-visual system. It aims at specific physical sites and specific time periods to advertise information to specific groups of people, so that it has the effect of advertising.

　　Digital signage market is the TV entertainment (TV) and personal computer (PC), Video wall the fastest growing application's third-largest LCD display products, show 'thin shape display ads' the time has come, is also the Chinese LCD industry embedded application of a new opportunity.

　　A new generation of cable digital signage also used broadband and wireless WiFi or 3 g communications and automatic fault response function to reduce operating costs and human needs, it also bring broadband providers corporate users of another successful application.

　　When you walk into the airport recently, MRT, buses, Fanless pc the building elevator, supermarket, store, or fast food restaurant, it is not difficult to find that the digital signage has gradually replaced the traditional entertaining diversions, such product presentation, for consumers to browse products, more pleasing, can also be product content and more flexible and diversified characteristics demonstrated, in the field of the new initiative, is currently the most popular digital signage.
