Machine discovery tour with our moderator on YouTube

Recently, YIZUMI has finally unveiled its milestone product, 8500-ton ultra-large high precision injection molding machine. It is the largest injection molding machine by now in China.

The 8500-ton ultra-large high precision injection molding machine has been hailed as one of the noticeable breakthroughs of YIZUMI. It is not only the largest machine ever to be installed in China in terms of tonnage, but also could meet the customer requirements in molding process relying on its advanced technologies, such as precision control technology, two-shot units co-injection molding technology, injection compression molding technology.

Deputy Managing Director of YIZUMI Group & General Manager of Injection Molding Machine Division, Zhang Tao introduced: "The R&D of the 8500-ton ultra-large high precision injection molding machine has taken a leading role in the development of large-scale injection molding machine for the whole industry. Our ultra-large injection molding machine is also occupying the leading position among our counterparts worldwide."

The great machine

The clamping force up to 9000 tons, setting industry record

Walking into the workshop of YIZUMI Wujiang factory, people can see the 8500-ton ultra-large high precision injection molding machine standing quietly like a marvelous cruise. This super large injection molding machine reminds people of their smallness but also the greatness of the engineers. How did they create such a heavy machine with their tiny bodies?

Zhang Min, deputy head of development section of technology department (Two-platen IMM), said the machine is about 27 meters in length and it generally takes 22.5s to walk around one time.The overall height of the machine exceeds 6 meters, higher than a 2-storey building. It covers 251 square meters, an area larger than 3 badminton courts. When it comes to the core components, a single platen weighs over 140 tons, equivalent to 23 Asian elephants.

"It took 4 months to assemble the whole machine and at least 30 technicians worked on it ". Zhang Min stressed, "In the past, the core technology of super large injection molding machine was mostly grasped by foreign enterprises. Now, the success of YIZUMI 8500-ton injection molding machine, of which the rated clamping force is 8500 tons and the maximum can reach up to 9000 tons, marked a significant breakthrough in key technologies for domestic ultra-large two-platen injection molding machines, and also set a new record of the ultra-large precision injection molding machine in China ".

Created by the ingenuity

Solving the molding difficulties of large-sized transparent plastic part in China

The 8500-ton ultra-large high precision injection molding machine is a key product that YIZUMI built with great effort in recent years. "Compared with counterparts at home and abroad, the most important innovation of this machine consists in its mold opening and closing repeatability up to ±0.3mm and two injection units with a maximum shot weight of 80 kg, breaking the record of ultra-large injection molding machine in China." Zhang Min introduced. It can be used in one-step molding of large-sized transparent plastic parts (or with metal inserts) with high requirement in part shape, light transmittance and accuracy, solving the molding difficulties of large-sized transparent plastic part in China.

Besides, the machine incorporates cutting-edge technologies in the industry, including injection compression molding (ICM) technology, SmartClamp technology, internal circulation two-platen clamping unit and closed-loop pump technology special for optical products. The control system integrates smart control technology, information technology and Internet technology independently developed by YIZUMI. And the machine is of high precision, high speed and intelligence, energy saving attained 30% compared with traditional three-platen machine.

The success of the first domestic 8500-ton ultra-large high precision injection molding machine is inextricably linked to the great efforts of YIZUMI R&D team. The machine is specially designed for the production of large-sized products, especially suitable for the fields of aerospace, automobile industry, petrochemical pipeline, transportation facilities, etc. Also, our problem-solving team has tackled a series of challenges in processing, transportation and assembly for ultra-large equipment, providing customers with more cost-effective integrated solutions for the manufacturing of ultra-large transparent plastic parts.

Promising future

Extending machine range to provide customers with integrated solution of large-sized plastic parts

With the rapid development of domestic aerospace and automobile industry, the demand for super-large injection molding products is gradually increasing. YIZUMI will continually develop new products, new technology and new process, to improve the integrated solution for super-large injection parts.

"Before, the maximum tonnage of YIZUMI injection molding machine was 4,500 tons. In the future, we will continue to expand tonnage range for all series machine, from 4,500 tons to 8,500 tons." Zhang Tao introduced. "It took two years from the initial negotiation with customers to the final prototype. When building this machine, there were many parts that our original supply chain could not provide, so our project team had to spend a lot of time exploring new suppliers."

At present, the prototype of 8500-ton ultra-large high precision injection molding machine has been built on target and now it is waiting for the final operation test when customer’s mold is in place. Zhang Tao said: "This machine can be regarded as a milestone for YIZUMI because it is currently the largest injection molding machine in China in terms of tonnage and shot weight."

"It’s more than big. The machine also adopts new technologies including injection compression molding technology and two-shot units co-injection molding technology." Zhang Tao stressed that the successful development of this machine opens a window to the application of large plastic parts and provides a lot of possibilities. It also plays a leading role in the development of large injection molding machine in the whole industry.
