Current Situation Of Injection Molded Parts China Industry

Current Situation Of Injection Molded Parts China Industry

Injection molding parts are the basic technological equipment of industrial production. Formulas have been obtained. In electronic, automobile, television, electrical appliances, instruments, instruments, household appliances and telecommunications products, 60% and 80% of the parts are molded by injection molding parts. The injection molding parts have high precision, complexity, consistency, high productivity, and low energy consumption, which are incomparable with other manufacturing methods. It is also a "benefit amplifier". The value of the final product produced by injection molding parts is often tens or hundreds of times the value of injection molding parts themselves. Specifically, taking the popularization of integrated manufacturing units and technologies for injection molded parts as an example, in recent years, in addition to the functions of automatic feeding, stamping, lamination measurement, thickness grouping, iron core combination and product output, hinge assembly and connection, injection molded parts have also emerged complex motion structure, in-mold heating, forging, local thermal (tissue) control, in-mold welding, tapping, local injection, In-die cutting, in-die testing and other process combination. For example, the application of 3D printing to produce an injection molding cavity is a new trend in the development of injection molding parts. The technology of metal material addition and material reduction combined manufacturing is an important direction in the field of 3D printing nowadays. High precision manufacturing of complex metal parts is realized by 3D incremental forming and high-speed milling. At present, the top three applications are industrial machinery, aerospace, and automobile, accounting for 20.0%, 16.6% and 13.8% of the market share respectively.


Injection-molded parts China industry developed late. The modern injection parts industry did not start until the end of the 1970s. However, after many years of efforts, injection molded parts China manufacturing industry has established a research and development institution including injection parts technology and injection parts by introducing mature design and manufacturing technology and independent innovation from developed countries and regions. The industrial system of injection molding parts, including the production and supply system, has made considerable progress in scale and technical level of injection molding parts industry.


Since 2012, the number of patent applications related to injection molded parts China has steadily increased. In 2017, the number of patents filed reached 22,872, exceeding 20,000 for the first time, a record high. In 2018, the number of patents filed decreased, but still exceeded 17,146, to 17,146.
