On April 9, 2015, Shell launched two new products for natural gas engines, R5NG and R3NG, to enrich its brand's product portfolio for natural gas lubricants. It is reported that these two products will be launched in China and will be launched in other countries in the world this year. Currently, Shell Rimula's full range of natural gas products include R6 LM, R5 NG, R3 NG and R2 CNG. Among them, the newly introduced R5 NG lubricant is verified by natural gas engines and road tests, and has a longer oil drain cycle, which can effectively reduce metal corrosion up to 90% and increase oxidation resistance by up to 50%. Another new R3 NG lubricant can provide even more exclusive long-term protection for the engine, reduce engine wear, and avoid the engine's high temperature environment, helping drivers to easily cope with various road problems. The R6 LM is the top product in the series and offers the best performance and long oil change intervals. The R2 CNG is presented to Chinese consumers as an entry-level oil product. Shell Shangyu, general manager of Shell Lubricant China/Hong Kong Marketing Department, said at the event, "As the largest international lubricants manufacturer and supplier in the Chinese market, Shell has always been committed to being a trusted partner and lubricant expert to the driver's friends. Always taking technical innovation as the basis for ensuring product competitive advantage and keeping up with user needs, this time, it has gathered its rich experience in natural gas and lubricants and its leading scientific and technological strength. It has introduced natural gas engine exclusive lubricant products and is committed to consuming in China. To provide better products and jointly promote the advancement and development of the entire lubricant industry." Heavy-duty vehicles using natural gas fuels have different combustion systems than diesel engines, so natural gas engines require dedicated lubricants. Natural gas is an energy-saving and environmentally friendly fuel, but because of its clean and dry nature, it does not produce heavy fractions. After combustion, carbon black particles are hardly generated in combustion chambers or in lubricating oils. This may result in lack of lubrication of the engine's valves. Therefore, it requires lubrication with adequate ash content. The oil is adjusted and balanced. At the same time, the combustion temperature of natural gas is higher than other hydrocarbon fuels, resulting in higher thermal stress, stronger oxidation and nitration of lubricating oil, which may cause sludge, carbon deposition, and film deposition on the engine. Therefore, balance lubrication is required. Oil formulations to optimize wear control, control acidity and corrosion, etc. Shell Rimbu natural gas engine oil series products not only help owners solve the needs of different types of natural gas engine vehicles, but also enrich the natural gas engine oil products on the Chinese market. From large fleets to city bus companies, from independent truck owners to passenger car drivers, Shell Natural Gas Engine exclusive lubricants can help owners solve the needs of different types of vehicle natural gas engines.
A mold is a special injection molding tool. Custom molded component manufacturers design and fabricate the mold specifically for the part they'll produce. When the production run for a part is finished, specialists replace the mold with a new mold for the next part they need to manufacture. Several types of molds exist for injection molding.
The mold determines the part's shape and size. It's also the special tooling in injection molding. When making large, complex parts, a mold may cost hundreds of thousands of dollars. When it comes to smaller parts, manufacturers can create molds with multiple cavities, adding to its cost. Incidentally, injection molding is most economical for large production quantities.
