As the concept of intensive production gradually netrates into the food field, a large number of packaging containers are needed for the transportation and circulation of food. In areas such as fresh, cooked, and take-out food, disposable plastic packages are often used as containers due to the extremely high hygiene requirements for packaging containers, and for reasons of cost . Because of the advantages of  lightweight, hygiene and low cost, disposable plastic containers have a wide range of alications in the food field, favored by merchants and consumers.

As one of the three major synthetic materials, plastic has developed rapidly since its publication and has been widely used in various fields. The plastic molding equipment is technological equipment to mold and process plastic and other new types of polymer materials for the need of plastic applications.And plastic injection molding machine is an important branch in the field of plastic machinery.

Ningbo Tongyong(UWA) Plastic Machinery Manufacturing Co., Ltd. (hereinafter referred to as "Ningbo Tongyong") is a company that has gone through more than thirty years and plowed in the field of plastic machinery. The company regarded "plant science and technology" as the development guideline.They not only integrate the world's advanced technology into innovative elements, but also popularize plastic machine products which possess unique Chinese innovative technology to the world. In recent years, Ningbo GM researchers have fully developed the YH428SP servo energy-saving thin-wall high-speed injection molding machine based on the full understanding and research of consumer terminals and market demands, starting from the needs of users and the market through its own technological innovation.

“Thin-wall high-speed injection molding machines mainly product disposable lunch boxes, milk tea cu, fresh packaging and so on. These products owns high production efficiency, short cycle, and also put forward more requirements to the the rapid stable molding ability of the equipment.”Mr. Yanqing Du, a senior technical engineer at Ningbo Tongyong, said in an interview of SL168.
