Haochen 20 years of focus on multimode cavities and small spacing hot runner

Six major gaps and development space for hot runner in China's plastic machinery industry. Although the development of China's plastic machinery industry can meet the needs of the domestic market, there are still six gaps compared to developed countries and regions that cannot be ignored

There are gaps in development concepts and models

Haochen hot runner: The plastic machinery industry in China initially started with imitation, and then determined what type of model to produce based on the demand of the plastic market. This passive decision is more suitable for the weak and small industry, the shortage of high-quality talents, and the shortage of economic periods. After decades of development, the plastic machinery industry in China has now begun to take shape, with a certain strength and a foundation for further development. At the same time, various industries are using plastic machinery, and the original The plastic processing industry dominated by plastic factories can no longer represent the buyer's market for plastic machinery. Therefore, it is no longer possible to copy the previous model, but rather to think about issues under the premise of being characterized by the buyer's market

Haochen Hot Runner introduces that according to the internationally popular model, advanced plastic machinery manufacturers have already penetrated into the direct consumer market. They continuously research, search, and discover the needs of the consumer market (including civil and industrial consumption), develop new types of plastic products on their own, and then design machines and arrange process formulas for this purpose, until providing equipment users with a turnkey project that includes processing equipment and can successfully produce a new product.

Haochen Hot Runner understands that this approach is completely different from the traditional passive mode of "producing whatever the user needs" of hot runner equipment, but rather a positive mode of actively guiding market consumption. To achieve this step, a large number of high-quality management talents with innovative spirit are required; We need a large number of high-quality scientific and technological talents across disciplines and industries; An effective, extensive, and cross industry social information circulation system is needed.

There are gaps in design concepts

At present, the popular design of plastic machinery in foreign countries is based on the demand for the products to be processed, and the concept of hot runner equipment is to enable users to win in the market, designing and manufacturing specialized equipment for equipment users. As a result, a large number of new technologies have emerged, such as three-dimensional circuit technology, double bubble tube membrane method, metal plastic processing technology, mixing and injection combination technology, co rotating twin screw direct extrusion technology, melt pump and hot runner technology, gas assisted and water assisted injection technology, etc., leading to the so-called "modular" design method.

There is a gap in efficiency and energy conservation

High speed, high efficiency, and energy conservation have been the main themes of international plastic machinery development in recent years. In this regard, most plastic machinery in China has high energy consumption, which is mostly twice that of similar foreign machines, and the speed is generally half that of foreign equipment; The product development cycle is about three times that of foreign countries, but the product lifespan is half that of foreign countries. Taking efficient and energy-saving injection molding machines as an example, Su Dongping pointed out that the energy consumption of domestic machines is 2-4 times that of foreign high-efficiency fully electric injection molding machines. High production efficiency extrusion technology, the development of high-speed and efficient plasticizing systems, and energy-saving, efficient, and fast response dual axis servo control systems all need to be further improved.

There is a gap in control level

Internationally, advanced computer control systems have been adopted to make equipment faster and more efficient. For example, the CANbus bus layout used in the automotive industry, advanced digital line control, networked control of multiple equipment in the workshop, and the establishment of a remote service system through the Internet.

The measurement and control technology in China lags behind that of foreign countries by 10-15 years, and there is a significant gap in control accuracy, product repeatability, and other aspects compared to the advanced level of foreign countries.

There is a gap in competitiveness

At present, the annual production of plastic machinery products in China accounts for about 25% of the world's total production, but the output value only accounts for about 9%. According to internationally recognized evaluation methods for enterprise competitiveness, the overall level of Chinese enterprises is significantly lower than that of international peers in terms of four parameters that demonstrate enterprise competitiveness: sales revenue, return on investment, research and development investment, and production scale and capacity.

In terms of equipment products, the gap between China's plastic machinery products and industrial developed countries such as Germany, Japan, and Italy is mainly manifested in low added value, limited variety, high energy consumption, low control level, and unstable performance.

There is a gap in equipment update concepts

Compared with Chinese enterprises that often spend hundreds of thousands or millions of foreign exchange to purchase advanced hot runner equipment from abroad, foreign enterprises do not always spend money on new equipment for their own equipment updates, but constantly renovate old equipment when conditions permit. The main content of the renovation is the control system. They will continuously update the control system and key components of old equipment until the current fully closed loop digital control. This not only improves the processing accuracy and level of the existing equipment of the enterprise, but also incurs lower costs.
