In recent years, with the "house economy" and the acceleration of the post epidemic era and the pace of modern life, ready to eat, hot and ready to cook prefabricated dishes have quickly emerged, becoming a new favorite on the table. According to the Research Report on the Development Trend of China's Prefabricated Vegetable Industry in 2022, the market size of China's prefabricated vegetable industry will be 345.9 billion yuan in 2021, which is expected to maintain a growth rate of more than 20%. It is expected to exceed 516.5 billion yuan in 2023, and may exceed the trillion mark in 2026.
At present, the prefabricated vegetable economy is entering a period of rapid growth, and all parts of the country have been focusing on the layout from the policy level. In fact, prefabricated dishes have not only become a new track for competition in the catering industry, but also their packaging has stimulated the injection molding market - thin wall injection molding.
As the name implies, compared with traditional injection molding, thin-walled injection molding has much thinner wall thickness of work in progress, but the more core or professional difference is the difference in flow length ratio. When the flow/wall thickness ratio (flow length ratio) is greater than 150, it can be called thin-walled injection molding. For large auto parts, the concept of "thin wall" can be 2mm. Thin wall has become a research and development hotspot in plastic molding industry due to its advantages of reducing product weight and overall dimension, facilitating integrated design and assembly, shortening production cycle, saving materials and reducing costs.
Due to the unique shape characteristics, thin wall injection molding has different requirements in the selection of raw materials, product design, machine selection, mold manufacturing and molding process. The five key points are interlocking. In a word, thin-walled injection molding machines are often inseparable from high-speed injection molding machines, and thin-walled products need to change the processing technology: higher pressure and speed, shorter cooling time, and change the ejection and gate arrangement of products.
Following the trend of thin-walled prefabricated vegetable packaging, many plastic machine enterprises have innovated and upgraded injection molding solutions for thin-walled packaging.
With the gradual differentiation of prefabricated dishes, a large number of packaging demands brought by prefabricated dishes also provide a new outlet for the development of thin-wall injection molding industry. Thin wall injection molding will also break the limit in terms of thinner thickness, higher efficiency, higher precision and lower cost. In order to seize the huge business opportunity in the prefabricated vegetable packaging market, we will wait and see what innovative equipment and processes will be introduced in the thin wall injection molding industry in the future!
