Question:
is how to do this kind of in this industry?
good or not?
Answer:
the direction of Chinas mold industry and prospect analysis
experts recently in an interview analysis, Chinas mold industry will be large, sophisticated, complex, high efficiency, long life and multi-direction.
At present, the electronics, automobile, electrical machinery, electrical appliances, instruments, meters, home appliances, communications and military products, 60% -80% of the parts depend on the mold shape. Molding of the workpiece with demonstrated high accuracy, high complexity, high consistency, high productivity and low consumption, other manufacturing methods can not match. Mold to a large extent determines the product quality, efficiency, and development capabilities.
Experts believe that Chinas mold industry will become increasingly large, and the accuracy will be getting higher and higher. 10 years ago, the accuracy of precision molds generally 5μm, now stands at 2-3μm. Soon, 1μm precision molds will be available. With the miniaturization of components and precision requirements increase, and some mold machining precision tolerance requires the following in the 1μm, which requires the development of super-finishing.
Experts believe that Chinas mold industry to further develop multi-functional composite die, a set of multi-die press forming parts in addition, also responsible for layers, tapping, riveting, and assembly tasks such as locking. Through this multi-functional out of the mold is no longer produced bulk parts, but the bulk of the components, such as contact with the bearing components, a variety of small motors, electrical and instrumentation of the core components. Multi-color and multi-material plastic molding mold will also have rapid development. This reduces the production mold cycle, the future will be developed in different areas and applications.
With the growing popularization and application of hot runner technology, hot runner molds in the plastic mold will gradually increase the proportion. Use of hot runner technology, the mold can improve productivity and quality of workpiece, and can greatly save workpieces of raw materials, the application of this technology has developed very rapidly in foreign countries has been very common. Domestic hot runner mold has also been produced, some enterprises has reached about 30%, but, in general, the ratio is too low, yet to be developed. With the plastic molding process of continuous improvement and development of mold and adapt to the high-pressure gas-assisted injection molding process will follow the development of mold.
Relevant experts believe that mold standard parts of the applications will be increasingly wide range of standard die and mold standard parts of the applications can greatly affect the mold manufacturing cycle. The use of mold standard parts can not only shorten the mold manufacturing cycle, but also to improve quality and reduce mold mold manufacturing costs. At the same time, rapid economic mold enjoy broad prospects. Because people asked mold production cycle as short as possible, so development of rapid economic die has drawn increasing attention. Such as the development of various superplastic materials, to produce mold; use epoxy, polyester, or in which the filling of metal, glass and other materials to enhance production of simple mold. Such mold manufacturing process is simple, precision, easy to control, less shrinkage, low price, a higher life expectancy. Can also be made with cement plastic auto panel dies. , The low melting point alloy mold, mold spray, electric molds, precision molds, stack mold, Plastic mold ceramic modeling and the use of light and heat curing rubber molds and other low-cost, rapid manufacturing will be further development of rapid economic mold. Quick-change die frame, quick-change red top will also be growing. Another use of computer control and mechanical hand-operated quick change die equipment, rapid test-mode device technology will be developed and improved.
experts believe that die-casting mold industry, the ratio will continue to increase. As the vehicles and lightweight motor and other products to develop in the direction of the die-casting mold number and complexity of life will make increasing demands. Along with the plastic on behalf of the steel, plastic and wooden parts of the development and product precision and complexity of the continuous improvement, the proportion of plastic mold will continue to improve its accuracy and complexity will also be along with a corresponding increase.

我国模具行业发展方向与前景分析
有关专家日前在接受记者采访时分析认为，我国模具行业将向大型、精密、复杂、gx、长寿命和多功能方向发展。
目前，电子、汽车、电机、电器、仪器、仪表、家电、通讯和军工等产品中，60％－80％的零部件，都要依靠模具成型。用模具成型的制件所表现出来的高精度、高复杂性、高一致性、高生产率和低消耗，是其他加工制造方法所无法比拟。模具在很大程度上决定着产品的质量、效益和开发能力。
专家认为，我国模具行业日趋大型化，而且精度将越来越高。10年前，精密模具的精度一般为5μｍ，现在已达2－3μｍ。不久，１μｍ精度的模具将上市。随着零件微型化及精度要求的提高，有些模具的加工精度公差就要求在１μｍ以下，这就要求发展超精加工。
专家认为，我国模具行业要进一步发展多功能复合模具，一套多功能模具除了冲压成型零件外，还担负叠压、攻丝、铆接和锁紧等组装任务。通过这种多功能的模具生产出来的不再是成批零件，而是成批的组件，如触头与支座的组件、各种微小电机、电器及仪表的铁芯组件等。多色和多材质塑料成形模具也将有较快发展。这种模具缩短了产品的生产周期，今后在不同领域将得到发展和应用。
随着热流道技术的日渐推广应用，热流道模具在塑料模具中的比重将逐步提高。采用热流道技术的模具可提高制件的生产率和质量，并能大幅度节约制件的原材料，这项技术的应用在国外发展很快，已十分普遍。国内热流道模具也已经生产，有些企业已达30％左右，但总的来看，比例太低，亟待发展。随着塑料成型工艺的不断改进与发展，气辅模具及适应高压注射成型工艺的模具将随之发展。
有关专家认为，模具标准件的应用将日渐广泛，模具标准化及模具标准件的应用能极大地影响模具制造周期。使用模具标准件不但能缩短模具制造周期，而且能提高模具质量和降低模具制造成本。同时，快速经济模具的前景十分广阔。由于人们要求模具的生产周期越短越好，因此开发快速经济模具越来越引起人们的重视。例如研制各种超塑性材料来制作模具；用环氧、聚酯或在其中填充金属、玻璃等增强物制作简易模具。这类模具制造工艺简单，精度易控制，收缩率较小，价格便宜，寿命较高。还可用水泥塑料制作汽车覆盖件模具。中、低熔点合金模具，喷涂成型模具，电铸模，精铸模，层叠模，陶瓷吸塑模及光造型和使用热硬化橡胶快速制造低成本模具等快速经济模具将进一步发展。快换模架、快换冲头等也将日益发展。另外采用计算机控制和机械手操作的快速换模装置、快速试模装置技术也会得到发展和提高。
专家认为，模具行业中压铸模的比例将不断提高。随着车辆和电机等产品向轻量化方向发展，对压铸模的数量、寿命和复杂程度将提出越来越高的要求。随着以塑料代钢、以塑代木的发展和产品零件的精度和复杂程度的不断提高，塑料模的比例将不断提高，其精度和复杂程度也将随着相应提高。
