我国模具工业现状

由于历史原因形成的封闭式、“大而全”的企业特征，我国大部分企业均设有模具车间，处于本厂的配套地位，自70年代末才有了模具工业化和生产专业化这个概念。生产效率不高，经济效益较差。模具行业的生产小而散乱，跨行业、投资密集，专业化、商品化和技术管理水平都比较低。

据不完全统计，全国现有模具专业生产厂、产品厂配套的模具车间（分厂）近17000家，约60万从业人员，年模具总产值达200亿元人民币。但是，我国模具工业现有能力只能满足需求量的60％左右，还不能适应国民经济发展的需要。目前，国内需要的大型、精密、复杂和长寿命的模具还主要依靠进口。据海关统计，1997年进口模具价值6.3亿美元，这还不包括随设备一起进口的模具；1997年出口模具仅为7800万美元。目前我国模具工业的技术水平和制造能力，是我国国民经济建设中的薄弱环节和制约经济持续发展的瓶颈。

1、模具工业产品结构的现状

按照中国模具工业协会的划分，我国模具基本分为10大类，其中，冲压模和塑料成型模两大类占主要部分。按产值计算，目前我国冲压模占50％左右，塑料成形模约占20％，拉丝模（工具）约占10％，而世界上发达工业国家和地区的塑料成形模比例一般占全部模具产值的40％以上。

我国冲压模大多为简单模、单工序模和符合模等，精冲模，精密多工位级进模还为数不多，模具平均寿命不足100万次，模具最高寿命达到1亿次以上，精度达到3～5um，有50个以上的级进工位，与国际上最高模具寿命6亿次，平均模具寿命5000万次相比，处于80年代中期国际先进水平。

我国的塑料成形模具设计，制作技术起步较晚，整体水平还较低。目前单型腔，简单型腔的模具达70％以上，仍占主导地位。一模多腔精密复杂的塑料注射模，多色塑料注射模已经能初步设计和制造。模具平均寿命约为80万次左右，主要差距是模具零件变形大、溢边毛刺大、表面质量差、模具型腔冲蚀和腐蚀严重、模具排气不畅和型腔易损等，注射模精度已达到5um以下，最高寿命已突破2000万次，型腔数量已超过100腔，达到了80年代中期至90年代初期的国际先进水平。

2、模具工业配套材料，标准件结构现状

近10多年来，特别是“八五”以来，国家有关部委已多次组织有关材料研究所、大专院校和钢铁企业，研究和开发模具专用系列钢种、模具专用硬质合金及其他模具加工的专用工具、辅助材料等，并有所推广。但因材料的质量不够稳定，缺乏必要的试验条件和试验数据，规格品种较少，大型模具和特种模具所需的钢材及规格还有缺口。在钢材供应上，解决用户的零星用量与钢厂的批量生产的供需矛盾，尚未得到有效的解决。另外，国外模具钢材近年来相继在国内建立

了销售网点，但因渠道不畅、技术服务支撑薄弱及价格偏高、外汇结算制度等因素的影响，目前推广应用不多。

模具加工的辅助材料和专用技术近年来虽有所推广应用，但未形成成熟的生产技术，大多仍还处于试验摸索阶段，如模具表面涂层技术、模具表面热处理技术、模具导向副润滑技术、模具型腔传感技术及润滑技术、模具去应力技术、模具抗疲劳及防腐技术等尚未完全形成生产力，走向商品化。一些关键、重要的技术也还缺少知识产权的保护。

我国的模具标准件生产，80年代初才形成小规模生产，模具标准化程度及标准件的使用覆盖面约占20%，从市场上能配到的也只有约30个品种，且仅限于中小规格。标准凸凹模、热流道元件等刚刚开始供应，模架及零件生产供应渠道不畅，精度和质量也较差。

3、模具工业产业组织结构现状

我国的模具工业相对较落后，至今仍不能称其为一个独立的行业。我国目前的模具生产企业可划分为四大类：专业模具厂，专业生产外供模具；产品厂的模具分厂或车间，以供给本产品厂所需的模具为主要任务；三资企业的模具分厂，其组织模式与专业模具厂相类似，以小而专为主；乡镇模具企业，与专业模具厂相类似。其中以第一类数量最多，模具产量约占总产量的70%以上。我国的模具行业管理体制分散。目前有19个大行业部门制造和使用模具，没有统一管理的部门。仅靠中国模具工业协会统筹规划，集中攻关，跨行业，跨部门管理困难很多。

模具适宜于中小型企业组织生产，而我国技术改造投资向大中型企业倾斜时，中小型模具企业的投资得不到保证。包括产品厂的模具车间、分厂在内，技术改造后不能很快收回其投资，甚至负债累累，影响发展。

虽然大多数产品厂的模具车间、分厂技术力量强，设备条件较好，生产的模具水平也较高，但设备利用率低。

我国模具价格长期以来同其价值不协调，造成模具行业“自身经济效益小，社会效益大”的现象。“干模具的不如干模具标准件的，干标准件的不如干模具带件生产的。干带件生产的不如用模具加工产品的”之类不正常现象存在。

China's mold industry Status

Due to historical reasons for the formation of closed, "big and complete" enterprise features, most enterprises in China are equipped with mold workshop, in factory matching status since the late 70s have a mold the concept of industrialization and specialization of production. Production efficiency is not high, poor economic returns. Mold production industry is small and scattered, cross-industry, capital-intensive, professional, commercial and technical management level are relatively low.

According to incomplete statistics, there are now specialized in manufacturing mold, the product supporting mold factory workshop (factory) near 17 000, about 600 000 employees, annual output value reached 20 billion yuan mold. However, the existing capacity of the mold and die industry can only meet the demand of 60%, still can not meet the needs of national economic development. At present, the domestic needs of large, sophisticated, complex and long life of the mold also rely mainly on imports. According to customs statistics, in 1997 630 million U.S. dollars worth of imports mold, not including the import of mold together with the equipment; in 1997 only 78 million U.S. dollars export mold. At present the technological level of China Die & Mould Industry and manufacturing capacity, China's national economy in the weak links and bottlenecks constraining sustainable economic development. 1、Research on the Structure of industrial products mold

In accordance with the division of China Mould Industry Association, China mold is divided into 10 basic categories, which, stamping die and plastic molding two categories accounted for the main part. Calculated by output, present, China accounts for about 50% die stamping, plastic molding die about 20%, Wire Drawing Die (Tool) about 10% of the world's advanced industrial countries and regions, the proportion of plastic forming die die general of the total output value 40%.

Most of our stamping die mold for the simple, single-process mode and meet the molds, precision die, precision multi-position progressive die is also one of the few, die less than 100 million times the average life of the mold reached 100 million times the maximum life of more than accuracy 3 ~ 5um, more than 50 progressive station, and the international life of the die 600 million times the highest average life of the die 50 million times compared to the mid 80s at the international advanced level.

China's plastic molding mold design, production technology started relatively late, the overall level of low. Currently a single cavity, a simple mold cavity 70%, and still dominant. A sophisticated multi-cavity mold plastic injection mold, plastic injection mold has been able to multi-color preliminary design and manufacturing. Mould is about 80 million times the average life span is about, the main difference is the large deformation of mold components, excess burr side of a large, poor surface quality, erosion and corrosion serious mold cavity, the mold cavity exhaust poor and

vulnerable such as, injection mold 5um accuracy has reached below the highest life expectancy has exceeded 20 million times, the number has more than 100 chamber cavity, reaching the mid 80s to early 90s the international advanced level.

2、mold industry supporting materials, standard parts of present condition

Over the past 10 years, especially the "Eighth Five-Year", the State organization of the ministries have repeatedly Material Research Institute, universities and steel enterprises, research and development of special series of die steel, molds and other mold-specific carbide special tools, auxiliary materials, and some promotion. However, due to the quality is not stable enough, the lack of the necessary test conditions and test data, specifications and varieties less, large molds and special mold steel and specifications are required for the gap. In the steel supply, settlement amount and sporadic users of mass-produced steel supply and demand contradiction, yet to be effectively addressed. In addition, in recent years have foreign steel mold set up sales outlets in China, but poor channels, technical services support the weak and prices are high, foreign exchange settlement system and other factors, promote the use of much current.

Mold supporting materials and special techniques in recent years despite the popularization and application, but failed to mature production technology, most still also in the exploratory stage tests, such as die coating technology, surface treatment technology mold, mold guide lubrication technology Die sensing technology and lubrication technology, mold to stress technology, mold and other anti-fatigue and anti-corrosion technology productivity has not yet fully formed, towards commercialization. Some key, important technologies also lack the protection of intellectual property.

China's mold standard parts production, the formation of the early 80s only small-scale production, standardization and standard mold parts using the coverage of about 20%, from the market can be assigned to, is just about 30 varieties, and limited to small and medium size. Standard punch, hot runner components and other supplies just the beginning, mold and parts production and supply channels for poor, poor accuracy and quality.

3、Die & Mould Industry Structure in Industrial Organization

China's mold industry is relatively backward and still could not be called an independent industry. Mold manufacturer in China currently can be divided into four categories: professional mold factory, professional production outside for mold; products factory mold factory or workshop, in order to supply the product works as the main tasks needed to die; die-funded enterprises branch, the organizational model and professional mold factory is similar to small but the main; township mold business, and professional mold factory is similar. Of which the largest number of first-class, mold production accounts for about 70% of total output. China's mold industry, decentralized management system. There are 19 major industry sectors

manufacture and use of mold, there is no unified management of the department. Only by China Die & Mould Industry Association, overall planning, focus on research, cross-sectoral, inter-departmental management difficulties are many.

Mold is suitable for small and medium enterprises organize production, and our technical transformation investment tilted to large and medium enterprises, small and medium enterprise investment mold can not be guaranteed. Including product factory mold shop, factory, including, after the transformation can not quickly recover its investment, or debt-laden, affecting development.

Although most products factory mold shop, factory technical force is strong, good equipment conditions, the production of mold levels higher, but equipment utilization rate.

Price has long been China's mold inconsistent with their value, resulting in mold industry "own little economic benefit, social benefit big" phenomenon. "Dry as dry mold mold standard parts, standard parts dry as dry mold with pieces of production. Dry with parts manufactured products than with the mold" of the class of anomalies exist.
