1 the meaning of financial riskYe at "small and medium-sized financial risk assessment and control of research" that the financial risk is the possibility of corporate insolvency and shareholders, the proceeds of uncertainty, it is difficult because of enterprise funds, to adopt a different mode of financing brought about by from the analysis of financial risk on its meaning, characteristics and types of content; at this based on the causes of the financial risk to conduct in-depth analysis and detailed research, analysis concludes that the financial risks arising from internal factors and external aspects; in turn, establish a risk awareness, the establishment of an effective risk prevention mechanism; set up and improve the financial management system to meet the financial management of environmental change; set up the financial risk early warning mechanism, strengthen the financial crisis management; improve the scientific level of financial decision-making to prevent due to poor decisions arising from the financial risk; through internal systems to prevent the establishment of binding mechanisms to control and guard against financial risk in five areas of financial risk prevention measures as well as self-insurance, diversification of risk control, risk transfer, risk averse, risk reducing the five techniques. Only controlled enterprises to guard against and defuse financial risks, in order to ensure that enterprises in the fierce competition in the market in an invincible causes of the financial risks(A) external causes1, the national policy changes brought about by the financing risk. Generally speaking, small and medium-sized production and operation because of instability. A country's economy or monetary policy changes, there may be small and medium-sized production and management, market conditions and financing forms have a certain impact. Beginning in 2007, our country has increased the intensity of macroeconomic regulation and control, the central bank to raise the fourth time the deposit reserve ratio, in particular, are ready to implement the difference between a direct deposit system to make small and medium-sized service-oriented small and medium-sized commercial banks to tighten credit, SMEs First of all, the capital supply disruption, the risk of inviting a lot of financing, SMEs also in urgent need of funds can not be forced to stop production or the scale of downsizing. 2, bank financing channels for non-financial risks caused by fluid. Corporate sources of funds are nothing more than its own funds and external financing in two ways. In various modes of financing, the bank credit is also an important source of funds, but banks in the country's financial policies as well as their own sound system is not under the influence of such circumstances, the general enthusiasm for SME lending is not high, their loans more difficult to increase the the enterprise's financial risk.(B) internal factors one, blind expansion of investment scale. There is a considerable number of conditions are not ripe for the SMEs in the circumstances, only the experience of one-sided pursuit of companies to determine the expansion of the extension, ignore the company's content and core competitiveness, resulting in a major capital investment wasted. 2, the investment decision-making errors. For business, the correct selection of industries are the starting point for the survival and development strategy. However, some industrial enterprises in the selection process, the often overlooked "industry is a dynamic selection process" concept, should not a keen grasp of industry trends and direction of evolution. 3, improper selection of investment partners. Enterprises to make investment decisions, we must give full consideration to qualified partners, reputation, and should have to bear the corresponding risks. 4, less than honest. Lack of SME credit is a common situation. Therefore, small and medium-sized banks to provide loans or investments to small and medium-sized people had to step up investment on human resources in order to improve the quality of information collection and analysis.

Precision injection molding technology of progress Abstract: The polymer precision injection molding technology, impact on precision injection molding of factors, including the precision molds, injection molding machine control accuracy, precision injection process control and other computer control technology. These factors were discussed, and give the relevant solutions, finally introduces some advanced molding technology. Key words: precision injection; injection molding machine precision injection technology; Precision Injection Mold In recent years, as electronics, telecommunications, medical, automotive, and other industries of the rapid development of the high-precision plastic products, and high-performance requirements of growing precision molding technology to continue to progress, new technologies continue to emerge. Precision injection molding products not only require high dimensional accuracy, and low warpage, to write good, but there should also be excellent optical properties. Injection molding is the most important one of the plastic molding methods, including plastics plastics, injection, packing, cooling, and some of the basic process, thus affecting the precision injection molding of many factors. 1, precision molds To produce sophisticated products, precision molds is essential. Die Die in general, the accuracy of the temperature control, mold and die design precision manufacturing, use of plastic shrinkage rate impacts. Precision Mold temperature control In general precision injection molding of parts, control mold temperature is to increase productivity. However mold temperature control for precision injection molding of great impact, it affects parts of the contraction, shape, crystallization, such as stress, hot and cold circuit design mold temperature distribution at the request reasonable, precise control accuracy, a die temperature of the best and Lengshuiji control. Mold temperature control and cooling time on the products and their impact on performance of the following factors: (1) melt plastic injection molds and a two-cycle time will be produced in the mold temperature difference fluctuations, and should therefore be to minimize the volatility differential peak. (2) the heat transfer Die Die Die heat through the concrete and die in the transfer out of the media, mold is changed, the media control is the key, the general import and export of its cooling water temperature difference is less than 1 ℃ Application of theory to calculate the average temperature, which can guarantee the stability of heat transfer. Media flow and heat transfer are interlinked, mould surface temperature can be used to control the media flow sensor to compensate for environmental temperature changes caused by mold temperature changes. (3) To enable stable Die Die by the heat absorption and dissemination of balance, the injection molding machine to melt injection to strictly maintain a stable temperature. Die surrounding temperature on the mold had a great impact on the general will be affected to die within the melt convection coefficient of change, so the best set up in the mold surface temperature sensor, die at any time observation of the surface temperature, and keep it stable. (4) changes in the efficiency of heat exchange with mold after a long time in the cooling water pipes and Youban appears in the scale, then the interface to reduce the thermal conductivity should furring timely clearance. Precision Die Design and Manufacture Die design is good or bad is to ensure the dimensional accuracy of plastic parts premise, in order to enhance the accuracy of precision injection mold, in the process of designing a computer-aided analysis is necessary, especially for gating system and the flow of heat-conditioning systems mold temperature distribution the analysis. Applications should be as much as possible the use of simulation software and close to the actual loading conditions to melt in the mold simulation analysis in the pouring, cooling, and other non-steady-state process. Die manufacturing quality assurance plastic parts Size is the key to accuracy, precision die is the main characteristic of the manufacturing and assembly operations in addition to polishing, are no manual processing. Die general machining and manual processing ratio is about 6:4 to 7:3, and the machining precision molds and manual processing ratio of 9:1. Die materials and heat treatment is the protection of precision molds in the molding process, the die temperature in the state, which even the mould parts tempered by low temperature, high temperature melt production and will repeat parts tempering而使lower hardness, Consideration should also be given retained austenite caused by the volume expansion. Therefore general tempering temperature should be at least molding processing, more than double the die temperature and low-temperature processing is carried out properly in order to eliminate residual austenite. On the high-precision products for Molding precision parts, assembly accumulated precision die in the direction of the accuracy of the sub-surface as well as the parallel degree should achieve micron level. Mold should have sufficient strength, stiffness and abrasion resistance, in the injection molding deformation under the pressure of hard wear. To achieve the above processing can be three-dimensional precision machining centers, CNC machine tool and application of CAD / CAM / CAE and other new technologies. precision molds design shrinkage rate of use Thermoplastic plastic molding shrinkage volatile, to mold design, identify and control products cavity size dimensional accuracy difficult. Therefore, in plastic mold design should understand the characteristics and contraction caused by the shape of the parts of the difference in the rate of contraction site, and then use the necessary compensation measures. On the high-precision plastic parts can be manufactured in the design before simple mold, measured molding to the various parts of the actual shrinkage rate, this can greatly enhance the dimensional accuracy of parts. , the design of precision molds gate Gate type, size, location and quantity of all affected parts dimensional accuracy. At the gate of the jet, but the effects of poor feeding, thick-walled parts do not apply. Gate position and the flow of impact melt flow distance, the longer the process of the greater contraction. Multi-gate process can be shortened, but increasing weld marks. Gate parts should be designed in accordance with the size and the choice of materials and the use of software to help finalize practical experience. 2, the best precision injection molding process parameters set Choose the best molding process parameters to reduce plastic shrinkage rate. Plastic is that the contraction of the heat shrinkable plastic, elastic recovery, plastic deformation, contraction after contraction and a comprehensive reflection of aging, usually caused by absorbent material or molecular chain rearrangement caused, the specific performance linear shrinkage rate and volume contraction rate changes in value of common contraction said. Thermoplastic plastic injection molding products shrinkage volatile, particularly for crystalline plastics injection molding products even more obvious, and not only depend on the degree of crystallinity due to the chemical structure, but also by the process of cooling parameters (cooling rate, the melt temperature, mold temperature , product thickness) the impact of the mold cavity size and design determine the size precision control products and difficulties, there is an urgent need to be aware of parameters on the injection molding of plastic shrinkage rate of the impact of the law. Part of the difference in thickness is generally believed that the two factors: First, high-pressure melt the mold cavity caused minor deformation of a die when the elastic modulus material after the expansion. Generally speaking, quality control and accuracy can be very good dimensional accuracy, and at a higher temperature, mold low melt viscosity, viscosity smaller gradient, in a certain screw back pressure, the quality of precision parts can be accurately controlled. But for liquid crystal polymer (LCP), it just needs a lower mold temperature, it is because cold LCP case will be promptly after cooling amorphous. LCP have low melting heat and orderly structure of the state, in the liquid crystalline state to change between crystalline solid, smaller changes, when fully cooling, the liquid - solid transition is almost complete in an instant. Die in the colder, when a cavity, the cavity material and the bulk of gate has been cured, it is very difficult stage compression added melt, thus parts and the size of the cavity size of the deformation is very close. Plastic amorphous than crystalline plastics low shrinkage with a mixture of contraction rate of low-polymer materials, elastomers at the same time as the increase of the content, materials shrinkage rate decrease. The enhanced or plastic filling, heat capacity decrease stiffness increased significantly reduce shrinkage and fiber filler content or higher, the smaller the rate of contraction. Crystalline precision plastic products also affected by pressure. As pressure crystallization of the role of injection pressure (P1), the packing pressure (P2) and the feeding pressure (P3) to speed up the crystallization process, crystallization of the P1, P2, P3, the increase in upward trend. For P1, the pressure to improve the crystallization of the degree of crystallinity, the contraction rate of increase rose P2 and P3, on the one hand because of the degree of crystallinity increased shrinkage rate increase, on the other hand increased to P2 more pressure to melt, the type cavity has been fully compacted plastic; P3-feed increased to increase, and effectively prevent reflux is conducive to reducing shrinkage. Therefore, the plastic parts of the shrinkage rate is the result of both, with the shrinkage of P1, P2, P3, the first increases and then decreases increased. Precision plastic parts requires not only a stable size tolerances, but also requires strict mechanical properties. These characteristics mainly depend on the cooling phase of the melt in the heat - mechanical role of the historical process. Mold temperature and cooling time on the quality of products and have a direct impact on productivity. Study found that, given the die temperature, the dimensional accuracy of products with the cooling time is not the extension has been significantly improved, and only in a certain period of time, after a prominent role. In general cooling process in such a critical point in time there are two cooling, cooling time in the first point although production products also higher accuracy, but it is not the most stable state, and the second point-in-time cooling cooling relatively long time, However, the products enable the most stable state. 3, using precision injection molding machine to replace conventional injection molding machine Precision injection molding machine generally larger injection power, in addition to such injection pressure and injection to meet the requirements in terms of speed, power itself will be on the injection products improve the accuracy of a certain role. Precision injection molding machine control systems generally have high control precision, it is requested by the products themselves. High accuracy can be guaranteed control of injection process parameters has good accuracy, precision products in order to avoid fluctuations due process parameters change. Therefore precision injection molding machine generally of the injection, injection pressure, injection rate and pressure-pressure, back-pressure and screw speed process parameters such as a multi-level feedback control. Precision Injection requirements of its modulus system has sufficient rigidity, accuracy or products will be a model for the elastic deformation decreased. Second-Die-Die of the system must be able to accurately control the size, or too large or too small a model of precision products will have an adverse impact. So in the design, it should be considered Die rigidity, stiffness, as well as a model system in order to accurately control the size of the precision products, especially flat-panel thin-wall products. When Die larger, must-oriented column deflection check. Precision injection molding machine also must be able to work in the hydraulic circuit precise temperature control, work to prevent the oil due to temperature changes caused viscosity and flow changes, further injection process parameters leading to fluctuations而使products would lose their accuracy. parts molding cycle time consistency General typical injection molding machine with three modes: manual, semi-automatic and fully automatic. As the influence of various factors, each of the previous two models molding cycle time may be different, it would affect the temperature and materials to die in the Liaodong stay, thereby affecting the accuracy of parts, in precision Molding should try to use the automatic mode. precision injection molding machine screw temperature control and the design of new Injection Molding Machine cylinder automatic thermostat on the cycle of opening and customs led to the Liaodong, melting material density and viscosity changes, thereby affecting the quality and dimensional accuracy of parts of the cyclical fluctuations in the injection molding machine nozzle close to Die Therefore, the temperature of the nozzle molded parts also have a significant impact on. Modern injection molding machine equipped with a special process control software to control temperature fluctuation, which is proportional integral differential (P ID) control. At least from the barrel temperature difference galvanic point perspective, the P ID parameter optimization can completely eliminate temperature fluctuations. To the quality and stability of the plastic parts, plastics injection molding machine unit is very important. To the plastics unit is an important standard to judge: injection volume, plastics rate, injection rate, the polymers in the plastics unit at the time. As the quality of plastic parts for the dimensional accuracy error of a very important impact, and it should be precise injection control of the injection molding machine. Improve measurement precision injection molding machine of the most effective ways is to use technology to achieve the smallest screw diameter, especially for the light parts especially. The measurement of the relative screw length and the overall length of screw smaller, in the plastics materials unit at the time also become shorter. Screw thread is similar to widening the materials can be avoided stay longer so that the screw and stable operation. Lo deep groove width than correspondingly smaller, which create a lot of engineering plastics parts of the small diameter screw particularly effective. Melt homogeneity and are not small compression ratio decreases, it is because from the very shallow groove Lo caused very strong result of the shear rate. Feeding the difficulty of the design, it must ensure that all aggregates can be fed into evenly. Considering the need to shorter cycles, plastics rate must also be big enough, in the design of the feed must be effectively resolved the contradiction between. In addition, if adopted by a two-stage injection screw to achieve precise control injection error, which requires the measurement of the melt through spherical valve detected by injection to injection molding machine in the Detroit injection molding machine. Before microprocessor controlled by the injection molding process can not be obtained through injection precision voltage comparator has been successfully resolved. Voltage comparator allows Transmitter and other sensitive came with the very precise voltage signal passed, and when the set point appears to be following the true value of a timely signal immediately transmitted to the microprocessor control of the order, by order of the cycle of operational procedures Asynchronous from time to time through a direct transfer of the signal process to eliminate, greatly improving the control accuracy. 4, precision molding technology in the mold injection-compression molding applications (ICM) technology ICM technology is the means to open a certain distance die under the conditions of the beginning injection, injection to a certain amount, the mold cavity beginning of the closure of the melt compression, injection mold completely closed at the termination, and then packing, cooling until the removal products. Through injection-compression molding of compression products to compaction, making products on the surface of uniform pressure distribution, the compaction products such size high accuracy and stability, small deformation. It is in the mould open circumstances melt into the cavity and, therefore, mobile channel, for the low pressure injection molding, and reduce or eliminate the pressure caused by the resin-molecular orientation of the stress and products, which improve products, dimensional stability. ICM technology and flexible control capability than the injection mould has greatly improved. Therefore use of this technology can produce more precision parts, especially the high-precision cylindrical-shaped parts. high-speed injection molding High-speed injection molding method of filling melts faster rate than the traditional 10 to 100 times, melt in the mold cavity to produce high shear flow, decrease viscosity, injection speed, slow down plastic surface hardening, thus improving thin Forming products wall thickness limit, inhibit excessive molding pressure, as well as because of the low-voltage mobile mode, the products reduce stress. The thin-wall precision products, we can use the injection screw at the forward from the melt energy absorption in the screw after the cessation of movement through the expansion of high-speed melt full cavity to achieve. no-pressure injection molding No-pressure injection molding technology refers to the plastic melt high-speed, high-pressure filling into the mold, and then close in the nozzle needle to melt the plastic mold cavity products automatically compensate for different parts of the contract, such products can be greatly reduced warpage. However, this method requires prior estimate packing contraction added, hence the need for the injection of a higher cavity pressure value, and we need clamping force also high. Other Intelligent Control Technology Precision injection molding processing conditions in the process of continuous monitoring and implementation of precise control is very important. With the development of computer technology, computerized injection molding has been widely used. Among them, statistical process control (SPC), P ID technology, fuzzy logic control (FCC), network control center (NNC) method and the processing model based on the reverse of the backbone network size control. 5. Conclusion On the high-precision plastic products, and high-performance requirements of the growing precision injection molding technology is the impetus for moving forward, people on the principle of precision injection molding, the constant deepening of understanding of precision injection molding technology is the basis for progress. With new materials, new processes and new equipment has emerged, particularly in the plastics processing computer is the wide application of the precision injection technology to create good conditions. As long as a reasonable use of these technologies, we will be able to produce sophisticated products.
