In 2016, Xi'an Cummins ISM Engine was unique in many products with its highly reliable quality. It won the recognition of the majority of truck drivers and won the "2016 Most Reliable Heavy-duty Engine" award. In 2017, Xi'an Cummins' ISM 11-liter engine once again won the 2017 China Truck Users' Most Trusted, Reliable Heavy-Duty Engine Award and won this award for its superior quality. This time in the voice of many users, Xi'an Cummins ISM engine won the consistent reputation of product reliability, can be described as a matter of fact. From product design, parts procurement, production and operation, complete vehicle matching to customer use and maintenance, Xi'an Cummins' strict control of every link in the value chain has laid a solid foundation for the high reliability of the ISM engine. Boutique factory is a reliable cornerstone The micro positive pressure workshop and clean production assembly line ensure the superior quality of the entire process. Original imported Cummins standard test bench, off-line 100% will be checked, to ensure that each finished product meets Cummins quality standards, to meet user needs. From the upper line to the lower line of the engine, each process is strictly controlled under the production and quality execution system. The entire process is dust-free and error-proof, resulting in reliable and excellent quality. Xi'an Cummins strictly abides by the Cummins supplier management system. All parts use Cummins global unified procurement standards. The cylinders, cylinder heads, and electronic control modules (ECM boards) are imported from the United States to ensure that the engine is synchronized with the quality of the world and can withstand Continuous verification of various users and various working conditions. The unique and reliable design of the product is a winning weapon Cummins ISM 11-liter engine has a highly efficient and simple machine structure, modular design, effectively reduce the weight and improve operational efficiency. Both the surface and interior of the cylinder block are designed with stiffeners to ensure lighter weight and better strength and stiffness than competitive products. Stop-type cylinder liner eliminates deformation of cylinder liner and avoids abnormal wear between piston assembly and cylinder liner. Articulated pistons can withstand higher mechanical and thermal loads, preventing cold and hot cylinders. In addition, Cummins ISM engine, engine oil thermostat, radiator and radiator bypass valve combination design to ensure the best working condition of the engine, effectively extending the oil replacement cycle. Better than the industry's inlet heating device, -45 °C start easily. At the same time, the four-step valve of the supercharging system can increase the response speed of the supercharger, prevent overheating and abnormal wear of the supercharger, and improve the life of the engine. Whether it is snow-covered forests in the snow, or in the northwest Gobi in the yellow sand, Xi'an Cummins ISM engine with reliable quality, excellent performance, partners all over the world, known throughout the world. The engine B10 has a design life of up to 2 million kilometers, 450 billion kilometers of verified million kilometers without major repairs, setting an industry benchmark for efficient operations. Countless customers all over the world have witnessed the high reliability of this engine with their own personal experience, which fully proves that the Cummins ISM engine is indeed a rare classic product. Rely on trust and trust! Xi'an Cummins thanked users from all over the country and even the world for their trust and choice. We will surely adopt a more rapid and proactive service concept, a comprehensive and considerate response system, and unceasingly excellent operation and management methods to help truck users become better. Tomorrow! Precision Casting Of Pump Valve Accessories
Pump valve accessories precision casting or pump valve accessories investment casting, silica sol process. It is a casting process with little or no cutting.
Cast pump valve accessories is an excellent process technology in the foundry industry. Its application is very extensive. Pump valve accessories cast not only applies to the casting of various types and alloys, but also produces the dimensional accuracy of castings. The surface quality is higher than that of other casting methods, and even castings that are difficult to cast and which are difficult to cast have high temperature resistance and are not easily processed can be cast using investment casting.
In wax pattern process,we mix stearic acid and paraffin wax in wax pattern making,as you know,it is better than polyethylene,and the wax deformation is small.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
In shell hardening process,we use aluminium chloride to harden the shell.This can make the shell so hard that it can`t be distorted,at the same time the bug which the casting may have will be decreased.If there are letters or numbers in it,they will be much clearer.
In dewaxing process,about 95% of the castings suppliers adopt the original water dewaxing technics,but we using the advanced steam dewaxing technics,which we are very proud of.This can effectively avoid the air-hole and sand-hole,making the casting look much nicer.
In smelt process,we use middle frequency furnace,avoiding the emergence of the oxide; in molten steel control part,we use Germany-imported direct reading spectrometer machine,assuring its quality before the molten steel out of the furnace.During this process we use ERP production and management software to get the feedback information.
In shell-knock out process,we have special machines,which can decrease the hitting and knocking, easily made by manual shell knocking out.
In shot-blasting process,we have crawler-type and hanging shot-blasting machine,with steel shot 0.5-0.8,making the products smooth.Of course,if the customer wants it look much nicer,we also can carry out sand-blast treatment.
In heat treatment process,we use electric furnace,and adopt double-temperature control in order to heat the products equally.As a result, the products will have great metallurgical structure.
Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.
In machining process,we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.

"Finding Trust - China Truck User Survey and Selection Activities" 
Win the 2017 China Truck Users' Most Trusted Heavy Heavy Engine Award 
Xi'an Cummins Engine 
Two Discovered Trust Trophies 
Discovery is a process. Trust is an attitude. "Finding Trust - China Truck User Survey and Selection Activities" is a selection activity that focuses on the true voice of truck users. For six months, the China Truck Network reporter traveled to major logistics parks across the country, issued and collected more than 20,000 questionnaires, and collected the most genuine voices and opinions of Chinese truck users. Therefore, it is highly representative and credible.
