Recently, Yizumi’s 8,500-ton super-large injection molding machine finally revealed its “true face of Mount Lu”. This machine can be said to be a milestone product of Yizumi, because it is the largest one among the injection molding machines currently produced in my country.
It is reported that the development of this 8,500-ton super-large injection molding machine is a major breakthrough for Yizumi. It not only created the largest machine in China in terms of tonnage, but also adopted precise micro-opening control technology, dual-shot synchronous plasticizing and injection technology. , injection compression control technology and other advanced technologies to meet the molding process requirements of customer products.
In this regard, Zhang Tao, Deputy Managing Director of Yizumi and General Manager of the Injection Molding Machine Division, said: “The research and development of the 8,500-ton super-large injection molding machine has played a leading role in the development of large-scale injection molding machines in the entire industry. At the same time, we have also achieved The leading position of super large injection molding machine in the same industry in the world.”
Great power
Clamping force can reach 9000 tons, setting a new record in the industry
Walking into the production workshop of Yizumi Wujiang plant, Yizumi’s 8,500-ton super-large injection molding machine stands quietly and solemnly. Standing in front of this super-large injection molding machine is like taking a photo with a cruise ship. People can’t help but sigh at their own insignificance, and at the same time admire the greatness of engineers, lamenting that they can create such a “heavy weapon” with a small body.
People who come and go can’t stand to measure. According to Zhang Min, Deputy Chief of the Development Section of Yizumi’s Second Board Machine Technology Department, the machine is about 27 meters long and takes 22.5 seconds from start to finish. The overall height of the machine is more than 6 meters, which is close to the height of a two-story building; the machine covers an area of 251 square meters, which is larger than 3 badminton courts. Its core component, a single template casting weight exceeds 140 tons, which is equivalent to 23 Asian elephants the weight of.
“It took nearly 4 months to assemble this injection molding machine, and at least 30 technicians participated in the development of this machine.” Zhang Min emphasized, “In the past, the core technology of super large injection molding machines was mastered by foreign companies. The successful development of a large-scale high-precision injection molding machine with a rated clamping force of 8500T and a maximum clamping force of 9000T has achieved a breakthrough in the key technology of domestic super-large two-platen injection molding machines, and has also set a new milestone in my country’s super-large precision injection molding machine industry. record.”
Ingenuity
Solve the problem of forming super large transparent plastic parts
It is reported that the 8,500-ton super-large injection molding machine is a key new product that Yizumi has made every effort to build in recent years. “Compared with similar products at home and abroad, the innovation of this machine is to set a record for domestic super-large precision injection molding machines.” Zhang Min introduced that the machine’s opening and closing mold positioning accuracy reaches 0.3mm, and it is matched with two sets of injection molding machines with an injection weight exceeding 80KG. The injection system can form super-large transparent plastic parts with complex appearance, high light transmission requirements and precise dimensions or dense texture with metal inserts at one time, which solves the problem of difficult molding of super-large transparent plastic parts in China.
In addition, this machine adopts the industry-leading low-pressure injection molding process, intelligent clamping parallelism control technology, servo-precision inner-circulation two-plate clamping structure, and dedicated servo closed-loop pump technology for optical products. The control system integrates the independent research and development of Yizumi. The whole machine has the characteristics of high precision, high speed, energy saving and intelligence, and the energy saving is more than 30% compared with the traditional three-board machine.
As the first set of injection molding machines with the largest clamping force in China, the 8,500-ton super-large injection molding machine embodies the wisdom and hard work of Yizumi’s R&D team, and is the result of the continuous pursuit of excellence by experts participating in research and testing. The machine can meet the needs of super-large products in the fields of aerospace, automobile industry, petrochemical pipelines, and transportation facilities, and at the same time solve a series of special difficulties in processing, transportation, and assembly of super-large equipment, providing customers with more cost-effective solution for oversized transparent plastic parts.
The future can be expected
Expand the model to provide customers with an overall solution for large injection molding parts
With the rapid development of the domestic aerospace and automotive industries, the demand for super-large injection molding products is increasing. In this regard, Yizumi continues to develop new products, new technologies, and new processes to improve its overall solution capabilities for super-large injection molded parts.
“Previously, Yizumi’s largest tonnage was 4,500 tons. Next, we will continue to expand to achieve a full range of models, with tonnage ranging from 4,500 tons to 8,500 tons.” Zhang Tao introduced, “The 8,500-ton machine will go from negotiating with customers to the end. It took two years to complete the prototype. When we built this machine, there were many parts that our original supply chain could not meet, which required the project team to spend a lot of time developing some new cooperative suppliers to complete the parts manufacturing with delivery.
“At present, the 8,500-ton super-large injection molding machine has completed the prototype development according to the predetermined target, and is waiting for the customer’s mold for the final installation test. In this regard, Zhang Tao said: “This machine can be said to be a milestone product for Yizumi, because it has been In terms of tonnage and injection weight, it is currently the largest injection molding machine in our country. ”
“Largeness is only one aspect. On this machine, we have also adopted new technologies such as injection compression molding and dual-shot synchronous injection.” Zhang Tao emphasized that the development of this machine can be said to help us in large-scale plastics The application of parts opens a very good window, increases a lot of possibilities, and plays a leading role in the development of large injection molding machines in the entire industry.
