【Customer Story】YIZUMI UN3200DP Two-Platen Machine at Otto - a U.S. Company in Waste Container Manufacturing Business for 85 Years
At the beginning of 2019, Yizumi had a good start in the overseas market. A 3200T two-platen injection molding machine UN3200DP-N-75500 is going to be added to the plant floor of Otto Environmental Systems, a waste containers manufacturer in U.S. This is by far the largest tonnage injection molding machine exported by Yizumi. The after-sales support and services will be provided by Yizumi-HPM Corporation, Yizumi’s North American subsidiary.
With its headquarters in Charlotte, NC, Otto has focused on waste and recycle since 1934. It now has become one of the world-known brands. Its products include domestic waste and recycling vehicles, commercial waste and recycling bins, trash cans, document safety boxes and special containers, such as medical waste containers and pharmaceutical waste containers. There are more than 10 million garbage trucks/containers produced by Otto and used in North America, Europe, Asia, and other regions around the world.
To replace some existing equipment and expand its capacity, Otto purchased this new Yizumi large-tonnage two-platen machine recently to produce 65-gallon (246 L) and 95-gallon (360 L) outdoor large waste container. Among them, the 95-gallon waste container weighs up to 12.5kg with 1.5m in height and approximately 1 m in length and width.
Otto is well experienced in making such large deep cavity product. It expects that UN3200DP can realizing high plasticizing rate, high injection pressure, as well as the high injection pressure, and shorter cycle time.
Therefore, Yizumi made a customized configuration based on UN3200DP to satisfy Otto’s molding requirements. While the product requires larger amount of injection due to the product weight (12.5kg), Yizumi designed the special high-plasticizing screw and added the high speed electric melt system to enhance the plasticizing rate, and synchronization for shorter cycle time. In the meantime, by optimizing the injection unit, the requirement for high injection pressure is also met.
The injection unit of UN3200DP-75500 is the largest integrating electric plasticizing system developed in Yizumi with standard linear guide rail, low resistance. Together with high rigid injection unit mechanism and monitoring by digital displacement transducer, it has achieved more precise position control accuracy and higher product repeatability.
“We’re very pleased to provide a high-quality product to one of the leading manufacturers of waste containers in the U.S.,” said Bill Duff, YIZUMI-HPM sales and General Manager of Marketing. “In the end, I believe we offered the greatest value in terms of technology, quality, and engineering—all at a competitive price.”
According to the production schedule, Otto’s Eloy factory can expect the delivery of the UN3200DP in February. In addition to the new injection molding machine, YIZUMI-HPM also provided a full automation package, which includes a three-axis liner robot, safety enclosures and conveyors. It will enable Otto to significantly improve its productivity
As to the first cooperation with YIZUMI-HPM, Michael Henry, Director of Procurement at Otto said, “We were impressed with the aggressive lead time and their intention to establish technical service facilities throughout the U.S.”

Relatedinformation
The largest injection unit integrating electric plasticizing system developed by Yizumi---75500
1. High rigid injection unit: The injection unit is made of high rigid ductile cast iron. Less deformation, more stable injection;
2. Double-parallel-cylinder injection: Easy to modularize, low resistance, fast acceleration, and precise injection;
3. Standard digital displacement sensor: Resistant to signal interference, high measurement accuracy;
4. Self-tuning PID Temperature control: performed by Austria s KEBA controller, with control accuracy up to±1℃, the heater bands have long service life and low energy consumption;
5. Quick replacement structure of material pipe: The material pipe is installed by pressure plate, which can directly lift and replace the material pipe, reduce labor intensity and improve maintenance efficiency;
6. Standard electric plasticizing system: Improve productivity and reduce energy consumption
Advantages of electric plasticizing system
(1) Energy-saving; compared to ordinary hydraulic motor drive, it saves energy by 20-30%
(2) Improve productivity; synchronized plasticization during product cooling and mold opening
(3) Low noise: operation noise is below 70dB
(4) Room-saving; compared to traditional hydraulic motor, it mitigates oil pollution by reducing the oil piping
