In addition to high strength and toughness, the surface performance of high-precision mold accessories is critical to the working performance and service life of high-precision mold accessories. It is very limited and uneconomical to rely solely on the improvement and enhancement of matrix materials to improve these properties. However, through surface treatment technology, we can often get twice the result with half the effort, which is the reason why surface treatment technology has been developed rapidly. Die polishing technology is an important part of die surface engineering and an important post-treatment process in die manufacturing. Because there are still some problems in domestic polishing technology and materials, for example, injection molds for point and shoot cameras, CD, VCD discs and injection molds with high transparency requirements for tools still rely on imports. The mirror mold material is not only a problem of chemical composition, but also a series of advanced processes such as vacuum degassing, argon protecting ingot, vertical continuous casting and rolling, and flexible forging are required to be used during smelting, so that the mirror mold steel has a series of advantages such as fewer internal defects, fine particle size of impurities, high dispersion, fine metal grain size, and good uniformity, so as to meet the requirements of mold steel polished to the mirror. The surface treatment technology of mold accessories is a systematic engineering that changes the shape, chemical composition, microstructure and stress state of the surface of high-precision mold accessories through surface coating, surface modification or composite treatment technology to obtain the required surface properties. Nitriding process includes gas nitriding, ion nitriding, liquid nitriding, etc. In each nitriding method, there are several nitriding technologies, which can meet the requirements of different steel grades and different workpieces. From the way of surface treatment, it can be divided into chemical method, physical method, physical chemical method and mechanical method. It is worth noting that the mold surface polishing is not only affected by the polishing equipment and technology, but also by the mirror degree of the mold material. This has not attracted enough attention, that is, the polishing itself is restricted by the mold material. Although new treatment technologies aimed at improving the surface performance of precision die fittings are emerging, nitriding, carburizing and hardening film deposition are mainly used in the manufacturing of high-precision die fittings. As the nitriding technology can form a surface with excellent performance, and the nitriding process has a good coordination with the quenching process of high-precision die fitting steel, at the same time, the nitriding temperature is low, there is no need for intense cooling after nitriding, and the deformation of high-precision die fittings is very small, so the surface strengthening of high-precision die fittings is the earliest and most widely used nitriding technology.

For a long time, the establishment of enterprises in China has been affected by the large and comprehensive, small and comprehensive. The enterprise has set up a mold production workshop, and the molds produced serve its own enterprises. This has resulted in few professional high-precision mold accessories factories in Dongguan. Even if there are professional high-precision mold accessories factories, the scale is not large. The management and production of many enterprises still need to be improved. The domestic leading enterprises of high-precision mold accessories play a leading role in the industry. They have perfect information systems and technical level, open the overseas market, and ensure the healthy and smooth development of the industry. However, in China's high-precision mold parts industry, the number and strength of leading enterprises need to be further improved. In the current wave of economic globalization, international division of labor is taking shape. Due to the pressure of cost, many foreign investors purchase a large number of castings in China, and even set up casting production bases in China. On the other hand, the manufacturing level and capacity of China's casting mold have been greatly improved, and the gap between the quality of high-precision mold parts and the international level has been narrowing. The high quality and low price of Dongguan high-precision mold accessories drive the sharp increase of foreign procurement. The huge demand of overseas high-precision mold accessories market has played a great role in promoting China's high-precision mold accessories industry. The slow growth in the demand of China's tool market is mainly due to the increase in tool life. In addition, users put forward requirements for the entire manufacturing process, replacing many machine tools and tools, and the increasing application of multi-functional tools, replacing many simple tools with single function. At the same time, due to China's ongoing industrial transformation and upgrading, the independent innovation of Dongguan's high-precision mold accessories industry is also gradually improving, and domestic high-end high-precision mold accessories have been recognized and purchased by foreign manufacturers. Therefore, this is very beneficial to the development of China's high-precision mold accessories industry. China's export of high-precision mold accessories last year has made remarkable achievements, which fully demonstrates that, The future advantages of China's high-precision mold parts industry are still obvious and the competitiveness is still strong. In recent years, China has used nearly 1 billion dollars to import high-precision mold accessories every year, of which precision, large, complex and long-life high-precision mold accessories account for the majority. Therefore, from the perspective of reducing imports, the market share of such high-end high-precision mold accessories and hardware tools will gradually increase. In the future, China's high-precision mold parts and CNC tool industry will also be among the best in the world.

The 21st century is a generation of science and technology. Die casting machines and die casting mold accessories are undergoing tremendous changes, and the use of die casting mold accessories is becoming wider and wider, which has driven the rapid development of the die casting mold accessories industry. Many businesses have joined this industry, making customers' requirements for die casting mold accessories manufacturers become higher and higher.

The precision mold accessories have the following requirements: 1. Cold and hot fatigue resistance Some moulds are heated and cooled repeatedly during the working process, which makes the surface of the mould cavity subject to tensile and pressure variable stress, causing surface cracking and peeling, increasing friction, hindering plastic deformation, reducing dimensional accuracy, and thus leading to mould failure. Cold and hot fatigue is one of the main forms of failure of hot working dies. Such Dongguan precision die accessories should have high cold and hot fatigue resistance. 2. Strength and toughness Most of the working conditions of Dongguan precision die fittings are very bad, and some of them often bear a large impact load, which leads to brittle fracture. In order to prevent sudden brittle fracture of die parts during operation, the die shall have high strength and toughness. The toughness of the die mainly depends on the carbon content, grain size and microstructure of the material. 3. High temperature performance When the working temperature of the die is higher, the hardness and strength will decrease, leading to early wear or plastic deformation of the die and failure. Therefore, the die material should have a high tempering stability to ensure that the die has a high hardness and strength at the working temperature. 4. Corrosion resistance When some molds, such as plastic molds, are working, due to the presence of elements such as chlorine and fluorine in the plastic, they decompose and release strong corrosive gases such as HCI and HF after being heated, which erode the surface of the mold cavity, increase its surface roughness, and aggravate wear failure. 5. Fatigue fracture performance In the working process of Dongguan precision die fittings, fatigue fracture often occurs under the long-term effect of cyclic stress. Its forms include low energy multiple impact fatigue fracture, tensile fatigue fracture, contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the die mainly depends on its strength, toughness, hardness, and the content of inclusions in the material.

At present, the domestic mold accessories industry is mainly concentrated in the southeast coastal areas, of which Chang'an and Hengli are the two towns leading the domestic mold industry. In addition to its unique geographical advantages, Dongguan's mold accessories industry has achieved such remarkable results mainly due to its leading technical level. Guangdong has many industries such as petrochemical, automobile, plastic, and high-tech. Relying on the demand of downstream industries of mold accessories, Guangdong has gradually developed into the most important mold and mold accessories market in China. At present, the output value of mold accessories accounts for more than 30% of the country. At present, among the top 10 mold enterprises in China, Guangdong has 5, and the world's largest mold base supplier and Asia's largest mold parts manufacturer are also in Guangdong. At the same time, Guangdong is an important member of the East China Economic Zone in China, with convenient waterway transportation, which can facilitate the distribution of molds throughout the country and export overseas. The development of mold accessories industry not only depends on regional advantages and technology, but also on its main strength. Guangdong's mold processing equipment's numerical control rate and performance, mold processing technology, production specialization level and standard level lead other provinces and cities in China. It has great advantages in the mold industry nationwide. In addition to these advantages, the development of Guangdong mold industry has also received strong support from the local government. Many favorable factors have promoted the development of Guangdong mold industry to a large extent. Relying on these advantages, Guangdong mold industry will achieve more brilliant achievements in the future.

For precision parts, processing is very strict, processing processes such as undercutting, out of the tool. For the size of specific requirements, precision requirements, such as 1mm plus or minus how many μm, etc., if the size of the wrong too much will become scrap, then it is the same as having to process again, time-consuming and labor-intensive, and sometimes even prompted the destruction of all processing raw materials, which led to the cost of raising, in addition, the parts are no doubt can not be used. For precision parts processing is mainly dimensional requirements, such as the diameter of the cylinder is how much, there are strict requirements, plus or minus the difference in the requirements of the requirements within the scope of the standard parts, otherwise all failed parts; size also has specific strict requirements, plus or minus the difference as required, for example, an embedded cylinder (take very simple basic parts as an example), if the diameter is very large, beyond the tolerance range of the difference, it will lead to, can not be inserted into the situation, if the specific diameter is very small, beyond the tolerance negative low limit, it will lead to put in very loose, not solid problems. It will lead to the situation that can not be inserted, if the specific diameter is very small, beyond the negative low limit of the tolerance margin, it will lead to put in very loose, not solid problems. This is all substandard products, or the cylindrical length is too long or too short, more than the tolerance range, all failed goods, are required to abolish, or again processing, which will certainly lead to increased costs. Precision parts processing requirements is in fact the main size problem, must be strictly in accordance with another plus drawings for processing, processing out of the specific size is undoubtedly not easy and drawings based on theoretical size of the same, only, only processing size within the tolerance range of the difference is all up to standard parts, therefore, the requirements of precision parts processing is in strict accordance with the basic theoretical size for processing. The next is the excellent precision parts processing machinery and equipment and testing instruments, excellent production equipment to promote the processing of precision parts in the case of more simple, high precision, the actual effect is stronger. Testing equipment can test out the parts that do not meet the requirements, so that all the goods sent to customers really meet the requirements.

Precision machining in the process of operation is a kind of processing equipment on the size of the product workpiece or is the process of changing the characteristics, precision machining according to the temperature of the processed product workpiece in the case, at a certain level can be divided into cold drawing and heat treatment. Generally processed at room temperature, and does not cause organic chemical or physical transformation of the product workpiece, called cold drawing. Precision machining is generally processed at high over or less than room temperature, that will immediately cause the organic chemistry of the product workpiece or the phase transformation of the material, reasonably called heat treatment, cold drawing according to the difference in processing methods can be divided into drilling processing and work pressure processing. Heat treatment commonly has heat treatment process, calcination, forging and welding welding. Precision machining is mainly the process of modifying the size or function of the product workpiece according to its various mechanical equipment. According to the temperature situation of the processed product workpiece, it is divided into cold drawing and heat treatment. In which the process of machining manufacturing means that there are some professional skills processes that are completed continuously for a product workpiece or a group of product workpieces at a detailed address in a work. The main characteristic of a process is not to modify the overall goal of processing, machinery and equipment and workers, and the content of the process is completed continuously. The expertise process can be divided into the following 2 processes.

Today's mechanical parts processing customers have higher requirements, the general precision machining can not meet their requirements, high-precision parts custom-made into their choice. In the case of sufficient assets, such customers will certainly choose to collaborate with the spare parts processing custom service management center, although the cost of high-precision parts customization will be higher than many, but the effect of mechanical spare parts processing customization is certainly worth the money. For the new product development company, the choice of the mechanical parts processing partner will determine the quality of their new products. If they have developed a new product, choosing a general hardware processing factory to show the effect effect will not help them to improve the product design. Only mechanical parts processing custom service can find various problems in the design of the product, and early to improve the design. The tooling is what makes the mechanical parts take shape. The various ways of tooling, such as the side of the ruler, the tool edge and the rate of wear behind the tool, are very harmful to the cold work hard layer. During the production of mechanical parts, the depth and strength of the cold-worked hard layer expands along with the reduction of the tool's foot side and the expansion of the wear rate of the tool kerf and its back. Different rates and cutting speeds of drilling, the hazards of cold work hardening are not the same. The cutting speed of mechanical spare parts machining expands, the tool touches the product workpiece for a shorter time, the plastic deformation level is small, and the cold work toughness are reduced to some extent. And the tool travel rate expands, the surface cold work hardening level increases, plastic deformation level increases.

Precision machinery processing industry and the integration of Internet technology will always exist a trace of mustiness. After China's reform and opening up, the natural environment of business services is constantly producing changes , CNC precision machining factory along the previous dividend period of blindly following the trend of expansion, many repeated capital investment, resulting in extreme overproduction apparently unsustainable. Many high precision parts processing professionals are gradually thinking about the transformation of the industrial chain development. At this stage of China's investment atmosphere also caused by the precision machinery processing industry is difficult to do some long-term deposition, socialized assets provide for short-term gains, precision machinery production and processing field is just a more delayed gains in the field. And state-owned assets "can not lose", can not lose means that only investment in some scale, the second half of the link precision machinery production and processing companies. In short, the low rate of return so that the field of precision machinery production and processing is difficult to get the pro-assets. China's social aging level aggravated, human capital provides lower, the population aging fading, to CNC precision machining factory has produced an unprecedented dilemma. In addition, the cost of human capital fees gradually increased, resulting in precision machinery production and processing company's winning indoor space continues to shrink. China's statistics bureau data information shows that China's processing manufacturing industry employment population since 2013 to date gradually reduced, while precision machinery processing industry manpower costs are gradually increased. 2018 processing manufacturing industry average income level has posted nearly 60,000 yuan. The transformation of human capital factors will become a metal catalyst for the transformation and upgrading of CNC precision machinery processing industry, and it is urgent to improve work efficiency. Along with the gradual increase of salary cost fee, the work pressure on CNC precision machining factory is getting bigger and bigger, only with the help of industrial structure upgrade and automation technology upgrade, China can complete the continuous growth of CNC precision machinery processing industry output rate.
