There is such a "legend" inside JAC. As one of the JAC Group's most popular companies, among the students of JAC University, only the best performers have the opportunity to join JAC Engine. It is not only a good working environment and good welfare, but also a high technological content and a large space for growth, which almost satisfies all the imaginations of graduates for future work. "In 2016, JAC Motor Co., Ltd. sold 375,000 units, an increase of 12.43% year-on-year, and both the sales volume, output value, and profit achieved the target." Wang Yunsheng, deputy general manager of Anhui Jianghuai Automobile Co., Ltd. engine company (abbreviated as Jianghuai Engine Company) told Commercial Automotive News reporter. In 2016, JAC Engine Company had a "small change" and a "big move." The small change means that the former engine company did not have a sales department, but now it has set up a sales project group; while the big move is a major marketing activity - at the Beijing International Auto Show that year, Ruijiete 2.0CTI diesel engine , 2.7CTI diesel engine held a listing launch ceremony, and Shuailing Bell, the country's five light trucks Junsui listed simultaneously. The combination of small changes and big moves is to strengthen sales and hit the market with the vehicle. In 2016, sales of light trucks in Jianghuai increased by 16.4% year-on-year, with the sales volume of domestic light trucks down 1.20% year-on-year. The reasons for this are directly related to the earlier preparations for the upgrade of the country's five countries, and great efforts in marketing and product competitiveness. “JAC Trucks ranks in the forefront of the domestic market and has a prominent industry status. However, if other brands are used, it is a shell manufacturing company that will lose its competitive advantage at any time. Improving the proportion of JAC engines is the key to enhancing competitive advantage. "Wang Yunsheng further explained:" Anjin, chairman of the JAC Group, said: 'Only selling cars does not sell engines, earning money for manufacturing; vehicle and machine integration, earning technical money' because of more technological content and added value of the engine." At the same time, the integration of the vehicle and the vehicle will also bring about the promotion of the brand, which in turn will earn the brand's money." JAC's famous "Golden Transmission System" together with the entire JAC vehicle, vividly interpreted what is called "JAC from the inside out." One of the advantages of Jianghuai is the integration of the vehicle and the vehicle. This advantage has already been verified on the JAC passenger car. “Before, Jianghuai Passenger Vehicle also adopted external distribution engines. By gradually building its own brand, now passenger vehicles will achieve 100% self-provisioning of engines, and the cumulative production of small-displacement engines will soon reach 1 million units.†Wang Yunsheng pointed out that passenger cars The successful experience of the engine can be copied to a commercial vehicle. Unlike the independent engine company, JAC Engine Company mainly provides internal support for the JAC Group; similar to the independent engine company, the JAC Engine Company also has to face competition from various brands of engines. "Competition with other engine brands depends on high quality and low cost," Wang Yunsheng said. Looking back to 2016, JAC Engine Company is well-received. 1.5 The TGDI products won the title of China's Top Ten Light Engines for the second time. This is also the reason why JAC has won 8 awards for 8 engines for 7 consecutive years. 1.5 TGDI Factory has won the national 5-star scene; under the background of self-branded automatic transmission or weak link , Jianghuai dual-clutch automatic transmission production and sales exceeded 20,000 units, to achieve bulk exports overseas. The Ruijie 2.7CTI diesel engine that was launched in 2016 and participated in the 6th IAC-reliable commercial vehicle selection is also commendable. This is a high-performance diesel engine independently developed by Jianghuai Automobile Co., Ltd. that satisfies the national five standard and possesses the potential of China VI. Its rated power is 112Kw, torque is 355N·m, and its power and torque are among the highest in the industry. The engine adopts 1800bar high pressure common rail injection system, adopts DOC+SCR emission control technology, adopts overhead camshaft single-cylinder four-valve gas distribution mechanism, and has high-performance turbocharging technology. Competing with mid- to high-end engines requires the establishment of a quality culture of excellence. Continuously advancing Six Sigma management is an important measure. In 2009, the company introduced Six Sigma management and continued the construction of Six Sigma quality culture, pursuing zero-defect quality. "About Six Sigma, we have 8 characters - true belief, true learning, true understanding, and true use. At the end of last year, after being awarded the advanced enterprise of the National Six Sigma Management Promotion in 2012, we were awarded the Advanced Enterprise of Six Sigma by the China Quality Association. He said. Today, JAC Engine Company has achieved the “Five Takes the Lead,†which is the first to introduce ISO/TS16949, take the lead in advancing Six Sigma management, take the lead in implementing nationwide site management star rating, take the lead in gaining CNAS certification, and take the lead in gaining an international QC Gold Award. In 2017, JAC plans to achieve 410,000 engines. The long-term goal of 2.7CTI diesel engines is to reach a production and sales scale of 100,000 units. “In the future, we will continue to develop products that meet higher emission standards, increase the proportion of commercial vehicles, and further expand into the pickup area and bus chassis.†Wang Yunsheng further stated that the sales volume of pickup trucks has improved significantly after lifting the ban. “The JAC 2016 The sales of 15,000 pickup trucks, especially the handsome bell T6, are very popular in the market, and Ruijiete 2.0CTI mainly matches pickup trucks." In view of future market expansion, JAC Engine Co., Ltd. mainly cooperates with Shuailing and Chunling Bell to participate in vehicle sales activities and display engine highlights, fully embodying the advantages of integration of vehicle and machine. In terms of services, the company has stationed dozens of service managers in various places, and has used its light truck marketing network to do a good job of engine service. “The management of “Running the customer†is one of Jianghuai’s core values. In terms of service, we emphasize customer care, increase customer information collection channels, and open 24 hours of 400 calls to solve 24 hours of general problems and solve problems. 2016 The company established a remote diagnostic capability for the engine, diagnosed engine faults and provided expert technical support through a remote diagnostic system to improve informationization capabilities, he said. Currently, Ruijiete 2.0CTI and 2.7CTI diesel engines are still in the start-up phase of the market, but they have been approved by users since they were put into batches. “The biggest advantage of the product is fuel saving. The minimum fuel consumption rate is 202g/KW·h, and the competing product is 210~215 g/KW·h. A customer in Dalian reported that under normal conditions, the average fuel consumption per 100 kilometers is only 9L.†Wang Yunsheng told reporters that at present, sales of Ruijiete 2.0CTI and 2.7CTI diesel engines are gratifying. Drainage, water comes. Just as JAC University students use JAC Engine as their ideal work unit, the products of Ruijiete with power, marketing, and service will become the ideal choice for light truck users.
At present, the five most commonly used thermosetting plastics in various fields are PU, epoxy resin (EP), silicone, unsaturated polyester (UP) and phenolic resin (PF).
Thermosetting plastic has the following advantages:
Thermosetting plastic has a large rigidity and is extremely elastic and plastic deformation.The temperature has little influence on stiffness, and under the same load and temperature, the creep variable is much smaller than thermoplastic.Good heat resistance;The plastic parts are quite stable when heated.The size of the plastic parts is good. Thermosetting plastic is less affected by temperature and humidity, and Thermosetting plastic can be reduced after forming, making Thermosetting plastic easy to make plastic parts with high precision than thermoplastic ruler.Excellent electrical performance.Resistance to arc and voltage, etc.Good corrosion resistance, weak acid, weak base and organic solvents;Good processability, can be processed by various molding methods and other advantages.
Most thermosetting plastics have the following characteristics:
(1) excellent chemical resistance.
(2) it is usually brittle hard plastic, which can be filled with various fillers to form composite materials.
(3) compared with thermoplastic resin, the molding cycle is longer.
(4) all kinds of modification can be carried out, depending on the combination of resin, crosslinking agent, additive, etc., which can form composite materials with different properties.
(5) good heat resistance, the use of high temperature, Tg of thermosetting polyimide (PI) is about 350 ℃.
(6) can be used as raw materials to meet the application of various fields.Only 5% is used as injection molding material.
(7) the waste is generally used as filler after pulverization, which is difficult to recycle and pollutes the environment.
Due to the high heat resistance of thermosetting plastic, good dimensional stability, good line performance, anti-aging properties are better than thermoplastic plastic and low price, so it is widely used.The disadvantage is that the mechanical properties are poor and need to be enhanced.
It is mainly composed of thermosetting resins, which are involved in various necessary additives to form the plastic of the products.In the process of manufacturing or forming, the liquid will be liquid, which will not melt after curing or melt or soften again.Common thermosetting plastics include phenolic plastic, epoxy plastic, amino plastic, unsaturated polyester, alkyd plastics, etc.Thermosetting plastic and thermoplastic plastics constitute two major components of synthetic plastic.
Thermosetting plastic heating for the first time can soften the flow, heated to a certain temperature, react a crosslinking reaction and curing hardens, this change is irreversible, since then, heating again, already no longer soft flow.It is the use of this characteristic to make the molding process, using the plasticization flow of the initial heating, filling the cavity under pressure, and solidifying to become the product that determines the shape and size.
Thermosetting plastic is distinguished by a chemical reaction that is hardened by heating, pressing or adding the hardener at a definite temperature.After hardening, plastic chemical structure changes, the texture is hard, dissolves in the solvent, heating also no longer softens, if the temperature is too high then decompose.In thermoplastic plastic, the chains of resin molecules are linear or branched, and there is not any chemical bond between the molecular chains, which soften the flow when heated.The process of cooling and hardening is a physical change.
Formaldehyde cross linked plastic includes phenolic plastic, amino plastic (such as urea-formaldehyde - melamine - formaldehyde, etc.).Other cross linked types of plastic include unsaturated polyester, epoxy resin, prevalence, diallyl ester resin, etc.
The commonly used thermosetting plastics are phenolic resin, urea-formaldehyde resin, melamine resin, unsaturated polyester resin, epoxy resin, silicone resin, polyurethane, etc.
Production:Phenolic resin PF (Bakelite sheet)
Phenolic resin is a part of the longest plastic varieties in history, commonly known as bakelite or electric wood, and the appearance is yellowish or black, which is the typical representative of thermosetting plastic.Bakelite sheet molding often use a variety of filling materials, according to different filling materials used, the product performance is also different, Bakelite sheet as molding material, mainly used in the field of need heat resistance, but also as a bonding agent used in plywood, grinding wheel and the brake pads.

The attraction of the car machine from the inside out
Facing competitive high performance more attractive
Advanced product technology, but also rely on production assurance, the company uses advanced manufacturing equipment and manufacturing processes to ensure product quality. “Before our products were mainly passenger car engines, passenger car users were more sensitive to product quality and required higher standards. When we built commercial vehicle engines, we followed the same philosophy and standards as those of passenger car engines. "Wang Yunsheng further explained that," For example, the company continued to carry out median management to improve noise, vibration and energy saving; perfect cleanliness management, each part has a strict cleanliness quality indicators, can be seen in some stations By drawing a big eye, this is where cleanliness is focused on the job, and the continued implementation of the 'eye-catching' project allows employees to receive bonus incentives if they spot defects at the production site. In short, various ways are used to encourage people to discover quality problems."
