Compression Molding Will Lead The Development Direction Of Future Packaging And Capping

Compression molding will lead the development direction of future packaging and capping

Since the mid-1990s, Coca-Cola's PET bottled beverages have replaced the aluminum cover with a plastic anti-theft cover, pushing the plastic anti-theft cover to the front of the beverage packaging. Since then, domestic powerful packaging companies and beverage manufacturers have introduced foreign equipment and started mass production and application of plastic anti-theft covers. Nowadays, the plastic bottle caps, which are both thin and easy to open, are spread all over the beverage market, which not only facilitates consumers, but also drives the rapid development of the beverage industry.

At present, due to the fierce competition in the domestic beverage industry, many well-known enterprises are adopting the latest production technology and equipment, so that China's production technology of capping machinery and plastic cover has the world's advanced level. World-renowned capping machines such as SACMI, Alcoa, Husky, Demag, Nestal, and Engel have entered China. Meanwhile,Jeepine have made a great progress in the  two technologies.We have wined the reputation of best quality,more stability,high precision in the world.

At the same time, in the field of plastic cap production, the battle for injection molding and compression molding has also opened. Undoubtedly, technological innovation is the driving force for development and progress.

1.Compression molding and capping lead the development direction of the future cap

The compression molding process is very simple, the quantitative materials are placed in the upper mold and the lower mold, and the upper and lower molds are closed, that is, the processing of the material is completed, and then the cooling, demoulding, and completion of the cover are completed. The injection molding process is like an injection, pushing the material to the gap of the mold until the gap is filled, then cooling and demoulding, and the cover is completed. Continuous Com-pression Molding (CCM) is a new breakthrough in the manufacturing process of plastic products in the past 10 years. It poses a strong challenge to the injection molding process (IM) that has a centuries-old tradition. In terms of comprehensive cost of energy consumption, material consumption and environmental protection, in the beverage industry, compression molding is undoubtedly the development direction of the current and future manufacturing methods.

At present, the compression-molded cover occupies more than 80% of Coca-Cola, Pepsi, Uni-President and Master Kong; Wahaha's tea drinks and soda, Huiyuan PET juice, etc. have reached 100%. The compression molding process accounts for 70% of the world's total, accounting for more than 60% of China's share. Although the injection molding machine has adopted the price reduction and various preferential promotions, the development trend of the compression molding process is not diminished. Since 2001, the number of compression molding equipment purchased by Chinese customers has greatly exceeded that of injection molding equipment.

2.Single piece hot filling cover is inexpensive

Since the tolerance of the bottle mouth is difficult to control to a predetermined range, the crystal PET hot-fill bottle is almost 100% matched with two pieces of cover. From the end of the last century, many companies have tackled the problem and tried to replace it with a single piece.

Since 2002, the world's petrochemical raw materials have generally increased in price, while the price of Chinese caps has declined. Therefore, it is more stimulating to seek newer technologies to reduce costs. The compression molding process has the advantages of accurate cover size and small shrinkage factor. Jeepine has been actively working with Chinese users to research and develop single-piece covers for hot filling, thus accelerating the process of the single-piece cover entering the practical process.

3.Combination cover fashion choice China Plastic Mould Net

People should remember that the sports cover of Nongfu Spring in 1998 first appeared in China. In less than three months, the sports on the market were overwhelming. With the integration of various cultures, it is inevitable that technological achievements will be presented in a fashionable way. Therefore, a new type of cover similar to the sports cover will appear in the gradual fashion of the Chinese beverage industry, which will make China's beverage cover more colorful and more eye-catching.
