2017 is a thriving year for the injection molding machine industry with strong results. According to incomplete statistics, the sale of entire market in 2017 has increased about 13% when compared with that in the same riod last year.

Plastic injection molding machine takes up a great percent of the plastic field and 80% plastics-made products are made through the way of injection. In recent years, with the expanding of high-precision injection molding parts alication area and the increasing of people’s awareness of environmental protection, demands for the  plastic injection molding machine with of high-quality are strengthened. Various types of precision, energy-saving, environment friendly injection molding machines continue to emerge, and the industrial structure is rapidly changing. Major manufacturers transformed to focus on all-electric injection molding machines production. All-electric injection molding machine trends to replace the hydraulic machine. Although the purchase cost in the early stage will be much higher than buying hydraulic ones, from the perspective of factory's long-term operation and product positioning analysis, the status of all-electric injection molding machine should not be underestimated.

When search the term of "all-electric injection molding machine", Ningbo Tongyong Plastics Machinery Manufacturing Co., Ltd. (hereinafter referred to as: Ningbo Tongyong) will  be impressively presented in the eyes.

SL168 as a professional media of plastic industry, with a lot of questions and curiosities, went to Ningbo Tongyong, and felt a great honor to have an interview with Mr. Yanqing Du, a senior engineer of Ningbo Tongyong.

"At present, the number of domestic manufacturers of all-electric injection molding machine is relatively small, and in this field we can be called the pioneers." Du Yanqing told the reporter confidently. "With technological accumulation in several years’, we do learn from the fusion technology, applying foreign advanced technology into the field of high quality all-electric injection molding machine. Many companies on the market just simply patch the technology together to form a complete product, which lacks core competitiveness.

When it comes to the difference between all-electric injection molding machines and traditional hydraulic injection molding machines, Yanqing Du said that all-electric injection molding machines own the advantages of energy saving, environmental protection, low noise and accurate metering. As one of the main products of Ningbo Tongyong, the all-electric injection molding machine avoids the defect of oil-spillage phenomenon of the conventional machines, abandons the hydraulic valve, adopts the servo motor, and controls the operation of the machine through the servo motor, the driver and the synchronous pulley. Compared with conventional hydraulic machines, the loss of energy be greatly reduced.

In 2017 Chinaplas exhibition, Ningbo Tongyong has exhibited a YE150W high-speed all-electric injection molding machine. The machine specializes in the medical, electronic and optic area. The machine is actuated by high-speed servo motors and high-load ball screw, A wide range of templates combined with the clamping device achieve high-speed cycle molding, the machine realizes the achievements of modular design with a variety of combinations of injection parts selection and a number of technologies won the national patents. YE all-electric series models meet the requirements of faster, more accurate and highly flexible demands and have greatly increased productivity and reduced costs.

The history of all-electric injection molding machine development in the domestic market is rather short. Then how can Ningbo Tongyong so quickly establish domestic and foreign markets of all-electric injection molding machine? What are the factors that make its all-electric injection molding machine stand out? Compared to the other all-electric injection molding machine industry, Ningbo Tongyong is equipped with what kind of advantages? Here are four points concluded by Yanqing Du ’s explanation.

1, Japan's leading technology support

Ningbo Tongyong has cooperation partnership with well-known Japanese injection molding machine manufacturers to fully orb the Japanese manufacturing process and technical standards. Compared with other firms, Tongyong’s all-electric manufacturing technology and mechanical structure are at top lists. In addition, employees have decades’ accumulation of all-electric precipitation and accumulation of technology and a wealth of experience in professional training. At present, Ningbo Tongyong’s all-electric injection molding machine production technology can almost be compared with Japanese. Also, it learned from the feedback from the market, combined with customers’ demand for products, launched domestic products for the Chinese market and reached the international advanced level at the same time.

2, Face the problem directly and Solve the problem efficiently

As the production of all-electric injection molding machine is still in the forefront in China, there are still many control system problems, including speed control and position control accuracy. When it comes to security, it is extremely important.

Yanqing Du gave an example during the research process, "Our control system was from Huichuan Technology Co., Ltd. When the first all-electric prototype is probed, something was wrong with response time of injection and it cannot meet our expectation. To solve this problem, Tongyong’s engineers together with the Huichuan presses control system research and development staff urgently discussed the response measures, and ultimately through the brainstorming of people put forward an effective solution. And this is one of the core technologies of all-electric injection molding machine.

3, Constant changes with the market feedback

After launching the all-electric injection molding machine to the market, Ningbo Tongyong’s technicians will regularly visit some of the larger agents and typical customers and go to the field factories to learn about the usage of the products, such as the current situation of all-electric machines and cost issues . Through the combination of market research feedback, Tongyong constantly updated the performance of products to meet market demands.

It is reported that in the current market, Ningbo Tongyong’s all-electric injection molding machine is already the second generation, and many improvements of key technologies have been achieved.

4, Fierce battles during the industry 4.0 to achieve intelligent manufacture

With the surging tide of Industry 4.0, the demand for intelligent injection molding machines has also become one of the focuses. It is reported that Ningbo Tongyong’s all-electric injection molding machines are equipped with a control system with networking capabilities, which could share data and parameters, and cooperate with the workshop management system (MES) to realize real-time monitoring. In the process of achieving Industry 4.0 and Smart Manufacturing, Tongyong created all-electric products that accord with the humane and intelligent requirements for our customers.

If an enterprise wants to be inherited through history, it should take measures with continuous innovation. This kind of innovation not only reflected in its own technology, but also in how to meet customers’ needs. "Science and technology plant" is Ningbo Tongyong’s strategic guidelines. Through scientific and technological innovation, it closely integrated with market demand and focused on researches and development of a series of high quality and efficiency of new products. Innovation is a long way to go, but Ningbo Tongyong is bound to step forward with determination and bring "China's intelligence-made products" to the world.
