01、Hot runner technology has broad development prospects

Although the application proportion of hot runner plastic molds is not high, hot runner technology is developing rapidly in the plastic mold processing industry. It is estimated that more than a quarter of injection molds are used in hot runner technology in Europe and more than a sixth in the United States. Abroad, hot runner system components have been serialized and commercialized. At present, the application of hot runner technology in plastic mold processing has reached 33.33%. Common hot runner technologies include internal heat, manifold and external heat.

However, in China, hot runner technology has been gradually applied since the 1980s and is still in the development and application stage. In injection molds, its application proportion is only about 2%-3%. However, the development prospects are good and the potential market demand is huge.

02、Technology development is subject to mold steel productupgrades

Although my country's plastic mold industry is developing rapidly, the technical content of products continues to improve and the manufacturing cycle continues to shorten. However, compared with the level of advanced foreign plastic molds, there is still a big gap. The mold industry is a stable customer of the steel industry and the main driver of steel product upgrades. The upgrading of the mold industry is limited to a certain extent by the development of high-end steel product varieties, quality and services.

More than 80% of mold steel produced abroad is produced by vacuum refining and electroslag remelting. The steel has high purity and isotropy. However, the proportion of mold steel produced by electroslag remelting in China is very small, about 10%. The plastic mold steels included in the national standards are only 3Cr2mo and 3Cr2mni, while the plastic mold steels commonly used abroad have formed a relatively complete series.

03、Technology continues to develop towards efficiency, large-scale and refinement

At present, plastic mold manufacturing accounts for 30% of the entire mold industry. Innovation in plastic mold processing technology is of great significance to the mold industry. As the application scope of plastic products expands, the requirements for product quality, form and quantity also increase. The development of high efficiency, large scale, refinement, intelligence, and automation has become an inevitable trend in the development of plastic mold processing technology. Processing technologies such as CAD, digital rapid scanning systems, and hot runners are gradually used in the processing and production of plastic molds, improving the quality and service life of the molds.
