Yizumi Develops an Eight-cavity Injection Molding System for Food Container Cover

Disposable food containers are low-value consumables. Generally, injection molding of such kind of thin-walled products requires high speed and low energy consumption to produce benefits. Only those manufacturers who are able to meet that requirement can be competitive in the market. But common injection molders still produce only 2 or 4 food containers every cycle. To create more value for customers, Yizumi’s technical team makes in-depth research on the trend of food container market and customer needs of the equipment, then works closely with the mold, material, manipulator suppliers and finally launches the first eight-cavity injection molding system for food container cover in the industry. The system consists of a PAC350 high-speed injection molding machine for thin-walled packaging, a 4 + 4 stack mold and a high-speed double-arm part removal manipulator.

Features of the system

Targeting the packaging industry, PAC series features high speed and high performance and it is widely applied to the manufacturing of thin-wall packaging, bottle caps, medical parts, etc.

According to Yizumi, the PAC350 thin-wall injection molding machine, which is part of the 8-cavity food container cover molding system, is equipped with a highly-efficient energy-saving efficient system, so that the cycle time is reduced to 4.3 seconds. Compared with the PAC250 injection molding system that produces 4 food container covers every 4.2-4.5 seconds, PAC350 doubles the production capacity and considerably reduces the energy consumption per part, which creates appreciable economic benefits for customers.

In terms of the quality of molded parts, the 8-cavity injection molding system has high degree of control accuracy so that the parts have high dimensional stability and flexibility and they are not fragile or not easily deformed, which ensures the food container is well sealed with the cover.

PAC series: more than high injection speed

When it comes to high-speed injection molding of packaging, it is generally believed that high injection speed is the only characteristic of a high-speed injection machine. But without coordinated support of appropriate design, “high speed” is just an empty talk. Adhering to Yizumi’s design ideas of high-speed injection molding, PAC Series has the features of a high rigidity, excellent configuration, high injection speed and low power consumption.  

In the production process, a high-rigidity and stable base is a strong guarantee for continuous high-speed operation of the machine. All mechanical parts of PAC series machines are designed to be highly rigid and more durable. The high-strength mechanical base increases the stability of the machine in operation. Devices with injection speed ranging from 100-800mm / s are also available and optional for PAC Series according to the needs of different configurations and processes, so that the machines can meet the needs of producing thin-walled packaging, bottle caps and medical products.

Custom and turnkey project

The packaging industry is a sector of rapid technological upgrades. When making the solution, Yizumi pays more attention to solve this problem: how to ensure that customers will not make repeated investment after buying Yizumi’s equipment and how to make sure the equipment meets diversified production needs in the future? Therefore, most of Yizumi’s solutions to high-speed injection molding of packaging are custom-made. Yizumi’s professional technical team gains insight into customers’ needs and the market    trends; they get familiar with customers' future product line planning and then create the best combination of an injection molding machine, mold, raw materials and auxiliary equipment, enabling customers to extend the production equipment if needed.

Yizumi can customize the equipment solution for different customers and also set up a turnkey project, covering earlier plant layout and planning, equipment selection, offer of auxiliary equipment, production line commissioning and personnel training. Whether hardware or software for high-speed injection molding of packaging, Yizumi is able to provide a one-stop, complete and detailed solution for customers.
