The main problems that exist are:
Poor scientific and technological innovation, the core manufacturing technology lags behind that of foreign countries, there are few products with independent intellectual property rights, and the varieties are incomplete. The level of product technology is different from that of foreign countries by about 15 years.
The investment intensity is low, the research equipment and production technology equipment are backward, the achievement level is low, and the product quality is poor.
The disconnection between science and technology and production has affected the transformation of scientific research results. The overall strength is relatively low, and the potential for industrial development is insufficient.
By 2020, the field of sensors and instrumentation components should strive to achieve three strategic goals: focus on industrial control, automotive, communications, and environmental protection, and focus on sensors, flexible components, optical components, and special circuits to develop autonomous knowledge. The original technology and products of property rights; Based on MEMS technology, relying on integrated, intelligent and networked technologies, strengthening the manufacturing process and the development of new sensors and instrument components, leading the leading products to reach and approach similar foreign products Advanced level; with the main objective of increasing variety, improving quality and economic efficiency, accelerating industrialization, so that the occupancy rate of domestic sensors and instrument components reaches 70% 80%, and high-grade products reach more than 60%.
Aluminum Deep Drawing Sheet is a kind of Aluminum Sheet suitable for deep drawing process.It has wide applications.The advantage of aluminum deep drawing sheet is as follows:
1. Easy to process.
The results show that the casting aluminum alloy with good casting property or deformation aluminum alloy with good processing plasticity can be obtained by adding certain Ba Au Du element.
2. Good conductivity and thermal conductivity.
The electrical and thermal conductivity of aluminum is second only to silver, copper and gold.
3. The density is small.
The density of aluminum and aluminum alloy is close to 2.7 g / about 1 / 3 of that of iron or copper.
4. High strength.
The strength of aluminum and aluminum alloy is high. The matrix strength can be strengthened by cold working to a certain extent, and some brands of aluminum alloy can also be strengthened by heat treatment.
5. Good corrosion resistance.
The surface of aluminum is easy to produce a dense and firm protective film of Al2O3, which can protect the substrate from corrosion.
