The following are four points worth noting in the Chinese instrumentation industry: First, China is a developing country, and the instrumentation industry has a gap of 10 to 15 years compared with developed countries. However, in the developing countries, China is the largest and most complete and most powerful country in the instrumentation industry. Second, China has a large demand for instrumentation and is one of the fastest growing countries. The growth rate of instrumentation in the world is 3% to 4%. China has achieved an annual growth rate of more than 20% for four consecutive years, and some products already account for one-tenth of the world's total. The third and first phases are mainly joint ventures and technology exports. The joint venture was transformed into a holding company in the second stage around the 1990s. Now it has entered the third stage, which is dominated by wholly-owned and merged Chinese outstanding companies. Fourth, some middle- and low-end products already have scale advantages and international market competitiveness. For example, ordinary digital multimeters and other products account for a large amount of production in the world, and the production capacity of household electric meters accounts for 50% of the world. At present, China has become a power meter, microscope, telescope, thermometer, pressure gauge, water meter, gas meter, and optics. The export of high-end products, such as the production and export of components and other products, and container inspection equipment, have also begun to make breakthroughs. Plastic Injection Insert Molding 1. The combination of the easiness of molding and bending of resin and the rigidity, strength and heat resistance of metal can make complex and sophisticated metal-plastic integrated products sturdily.

2. In particular, the combination of the insulation of resin and the electrical properties of metal can meet the basic functions of electrical products.
3. The pre-forming combination of multiple inserts makes the post-engineering of product unit combination more reasonable.
4. Insert products are not limited to metal, but also cloth, paper, wire, plastic, glass, wood, wire ring, electrical parts and so on.
5. For rigid parts and flexible parts on rubber sealing pad, the complex operation of arranging sealing ring can be eliminated after the integrated products are made by injection molding on the matrix, which makes the automatic combination of the following process easier.
6. Because it is the fusion of molten material and metal insert, compared with the pressing molding method, the metal insert gap can be designed to be narrower, and the reliability of composite product molding is higher.
7. Suitable resin and molding conditions may be used for sealing and fixation of susceptible products such as glass, coils, electrical parts, etc.
8. Inserts can also be completely sealed into the resin by selecting the appropriate mold construction.
9. After the insert is molded, it can also be made into a product with hollow grooves along with the core hole.
10. The combination of vertical injection molding machine and manipulator, the whole row device of insert products, etc., the insert forming engineering can be mostly automated production.
