On December 2nd, 2014, the “The 4th Identified Commercial Vehicle Power Evaluation†activity held an awards ceremony in Beijing. Sinotruk MC series engines won the “China’s Most Trusted National Heavy-duty Engine†award. Assistant President of CNHTC Group and CEO of China National Heavy Duty Truck (Hong Kong) Co., Ltd. Jinan Power Department, Mr. Hu Bokang, presented a speech on behalf of China National Heavy Duty Truck and made speeches on behalf of the winners. In the evaluation, the assessment team composed of the leaders of the association, industry experts, university scholars, representatives of logistics companies, etc. highly evaluated the technical indicators of China National Heavy Duty Truck MC series engines. Hu Bokang said in his speech that in order to achieve a leap from the domestic leading to the international advanced level, Sinotruk successfully reached a strategic cooperation with the German company in 2009 and introduced the synchronization technology of its flagship product. The award-winning MC series engine is a localized product of MAN Engine technology. Its power coverage can reach 310Ps-540Ps, meeting the Euro V emission standards. The application of vermicular cast iron materials, the up-and-down process, and the modular design of parts and components have greatly improved the reliability and economy of the product; the engine B10 has a life of up to 1.5 million kilometers and defines a new standard for domestic high-end heavy truck engines; The interval between oil changes in the normal maintenance and the later period is 80,000 kilometers or 12 months, which significantly reduces the user's use cost. Up to now, China's heavy trucks have installed MC series engines, the number of vehicles put on the market has exceeded 15,000, and the maximum mileage has exceeded 600,000 kilometers. The power, economy and reliability of the vehicles are well received by users. It is reported that in the face of the National IV switching that began on January 1, 2015, China National Heavy Duty Truck has fully prepared itself in terms of technology, products, and market development. Water-assisted injection molding: Water-assisted injection molding technology is an advanced injection molding process in which part of the melt is injected into the mold cavity and high-pressure water is injected into the melt through the equipment to finally shape the workpiece.
Due to the incompressibility of water, the water front creates a solid interface, squeezing the inner wall of the product into a cavity, and the water front also acts as a rapid cooling. Therefore, the water supplement has many advantages over the gas supplement. Research and application show that the water supplement can produce thinner and more uniform cavity wall, and the inner surface of the flow channel is very smooth. Especially for thick wall workpiece, the cooling time can be greatly reduced compared with gas auxiliary.

High gloss injection molding: Highlights the basic process of injection molding is prior to injection molding, through the use of high temperature and high pressure steam will mould surface rapidly warming, the forming die cavity surface temperature of resin plastic glass transition temperature (Tg) above, then the plasticizing good plastic melt into the closed mold cavity, the injection stage, mold temperature by high temperature and high pressure steam remains the same, When the injection is finished, the air supply is stopped, and the water vapor in the pipe is blown clean by air pressure of the air pipe. After that, the cooling water is injected to make the mold temperature drop rapidly until the mold is cooled and the product is removed by opening the mold
