The mould industry in our country in developing, seek breakthrough in slowly. After many years of hard work now has a set of their own industry chain, although the technology gap still exists problems, but through the baptism of the time we go to a higher level of industry.
"Mold industry" twelfth five-year "development plan" points out the mould industry in China with the international advanced level of the main gap: mould service life by 30% ~ 50% lower, precision die life usually only 1/3 of the foreign advanced level; Production cycle should grow by 30% ~ 50%; Poor quality reliability and stability; Low degree of accuracy and standardization.
In the research and development capabilities, personnel quality, on the basis of mold design and manufacture theory and technology research also there exists a large gap, cause mould new areas of development and new product development speed is slower; Highly skilled mold with much lower abroad; Labor productivity is low; Standard parts production and supply lags behind that of mold production speed, some high-grade mold standard parts is still blank, so we have to import a lot of.
Although the mold standard parts industry in our country after decades of rapid development of China's reform and opening up, has been basically forming a more comprehensive, the basis of a larger industry as a whole. Especially in recent years, the increase in the number of new varieties has been die standard parts, production scale year after year to expand, constantly improve the technology level, basic can meet the demand of the market, but due to the market competition is intense, industry extension is relatively extensive, structural contradiction, lack of core technology, a disparity between the quality of the product, mid-range products supply, high-end product competitiveness is not strong, embodies in the following aspects:
1, the standard technology standards formulated or revised lags behind the development of mold industry. Along with our country of the mold into exports increased, imported mould maintenance, domestic and foreign-funded enterprises to form a complete set of mould standard requirements, all need mould standard parts production enterprises to master and use different national standards and enterprise standards to produce standard parts.
At present, the use of the standard sort is more, including Japan, Europe and the United States the famous standard dominant standard parts manufacturers. Level of mold standard parts production technology in China in recent years, although progress quickly, the quality has been improved, new varieties also increased considerably, but most directly use the well-known enterprise standards, such as Japan, the United States for complex standard parts, such as oblique wedge mechanism, in the process of the flanging linkage and other standard parts movement principle and the structure stress conditions, lack of theoretical analysis and data calculation, the accumulation of constraints to improve the innovation of the structure of standard size. So should speed up the precision mold localization of advance work abroad, actively formulate relevant national standards and industry standards.
2, the introduction of digestion and absorption of foreign standards, low technical content of standard proportion is still on the high side, the formation of foreign brands of domestic brands eroded. At present, the existing part of standard enterprise has a certain capacity for independent development, but due to the independent innovation ability is weak, weak foundation, development ability is insufficient, less input, not enough attention, lack of long-term sustainable development idea, cause the product technology content is not high. New mold standard parts in the research, development work is mold standard parts of the weak link in our country, needs to be strengthened. In addition, foreign brand into the domestic, the early looking for agency domestic suppliers, and many domestic enterprises become the OEM supplier, its own brand shrinking market coverage, the column in Shanghai international exhibition on die & mould technology and equipment, the "precision mold award" to declare the number and die standard parts production enterprises to obtain the number of technology patents, and not on the mould manufacturing enterprises, should be taken seriously.
3, the quality of raw materials, and poor equipment. Die standard parts need some special material and heat treatment process, the domestic is still unable to satisfy. On the one hand, domestic standard of raw materials in terms of variety, quality, quantity, to meet the needs of mold standard parts production enterprises. Most domestic die standard parts enterprises, on the other hand, using traditional general machinery processing equipment and tooling to production. If want to change this situation, we should adopt the introduction of absorption, joint development, development of key components, modular development and so on many kinds of ways, changes the backwardness of China's die standard parts manufacturing as soon as possible.
4, cost rapid increase, the enterprise pressure. In recent years, die standard parts falling prices, and raw material prices are rising, plus the enterprise first and second line of the labor cost is also rising, mold standard parts enterprises by the multiplicity of cost pressures. Therefore, to speed up the adjustment of enterprise operation structure and product structure, improve technology, strengthen the technological transformation and development, improve product technology content and productivity, has become the consensus of mold standard parts enterprises and enterprise managers conscious action.
5, is of great importance to regulation, market order is an urgent need to develop mould standard parts industry "guild regulations", so as to effectively curb the mold standard parts market competition. Parts enterprises at present, in order to fight for market share, not by the quality and level of ascension innovation ability to improve the development of the enterprise itself, but rather through frequent prices, disorderly competition, this will inevitably lead to decline in the quality, caused by cutting corners, the sham as the genuine and hurt many businesses, resulting in a decline in mold industry overall profits, some companies even to the edge of the losses.
6, backward sales link, weak. Marketing chain plays an important role in the mould standard parts market, trade type enterprise is the most main mold standard parts, small size, low inventory is not much, sales. Though an individual sales company, has begun to implement online marketing and e-commerce, but started the job soon, it will take time for to form scale.
To develop the key products and technologies
Die standard parts industry should be in accordance with the "twelfth five-year" state to formulate goals and strategies in the mold development plan. Is actively promote mold production informatization, digitization, refinement, automation, standardization, strengthening the combination of production, use, promote the improvement of innovation and research and development ability. Actively developing high-grade die standard parts and mold base parts. In the process of execution, to realize the requirements of the "twelfth five-year" plan key: "the key breakthrough of a batch of basic components manufacturing technology, product technology reached the international advanced level of the early 21st century".
Focus on the development of standard product is high-grade mold standard parts, mainly including hot runner components, nitrogen gas spring, special oblique wedge. National "twelfth five-year" mold development planning requirements, the biggest influence on mold production two standard should be first breakthrough, namely life 1 million times mold with high pressure nitrogen gas cylinder and temperature control accuracy is + / - 1 ° of hot runner system. In addition, inclined wedge mechanism plays an important role in stamping die, oil free putting ejector sleeve is also very important in precision plastic mold, all should belong to vigorously develop high-grade mold standard parts.
Focus on the development of mold standard parts production technology including: piston, piston and cylinder precision machining technology; Seal reliability and safety technology; Hot runner material and precision temperature control technology; Hot runner nozzle precision machining technology; The plastic flow in the cavity three-dimensional computer simulation technology; New high-grade inclined wedge design technology and research and development and processing technology of oil-free lubrication wear-resistant materials. The six production technology represents the current mold standard parts production and product of the advanced level, should be a period of time focus on developing direction in the future.
To sum up, both countries related departments and mold enterprise itself, the industry adjustment is inevitable. The formation of a new industry chain is not easy, to maintain and develop this chain is not easy. , and from the action on thought to consider all aspects.
