Pressing plastic caps is the direction of beverage packaging

since the mid-1990s, PET bottled beverages produced by Coca Cola company have used plastic anti-theft caps instead of aluminum caps, thus pushing the plastic anti-theft caps to the front stage of beverage packaging. Since then, powerful domestic packaging enterprises and beverage manufacturers have introduced foreign equipment and began the large-scale production and application of plastic anti-theft covers. Nowadays, plastic bottle cap packaging, which is both light and easy to open, is 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 using Jinan testing machine to compile the assembly process procedures. The latest production processes and equipment have made China's capping machinery and plastic lid production technology level with the world's advanced level. World famous capping machines such as SACMI, Alcoa, husky, Demag, nestal and Engel have entered China

at the same time, in the field of plastic bottle cap production, the debate between injection molding and compression molding technology has also begun. Undoubtedly, technological innovation is the driving force of development and progress

press plastic cap making leads the development direction of cap making in the future

press plastic process cap making is very simple. Put a certain amount of materials into the upper and lower molds, and the upper and lower molds are closed, that is, the processing of materials is completed, and then cooling, demoulding, and cap making is completed. The injection molding process is like injection, pushing the material to the gap of the mold until the gap is filled, mainly including reverse coating technology, and then cooling and demoulding to complete the capping

continuous com compression molding (CCM) is a new breakthrough in the manufacturing process of plastic products in recent 10 years. It poses a strong challenge to the 100 year old tradition of injection molding (IM). From the perspective of energy consumption, material consumption and environmental protection, in the beverage industry, plastic capping is undoubtedly the development direction of capping methods now and in the future

at present, pressed plastic covers account for more than 80% of Coca Cola, Pepsi Cola, uni president and Master Kong; Wahaha's tea drinks and soft drinks, Huiyuan pet juice and so on have reached 100%. The pressure plastic capping process accounts for 70% of the global share and more than 60% of China's share. Although the injection molding machine has successively adopted price reduction and various preferential promotions in terms of the testing and use of the experimental machine, we comply with the customer's standards, the development trend of cover making by compression molding process remains unchanged. Since 2001, Chinese customers have purchased more compression molding equipment than injection molding equipment

the cost of single piece hot filling cap is low

because the bottle mouth tolerance is difficult to control to the predetermined range, almost 100% of crystalline pet hot filling bottles need to use two pieces of caps to match it. Since the end of last century, many enterprises have tackled key problems and tried to replace them with single-chip covers

since 2002, the price of petrochemical raw materials worldwide has generally increased, while the price of bottle caps in China has decreased. Therefore, people are more stimulated to seek new technologies to reduce costs. The compression molding process has the advantages of accurate cap size and small shrinkage coefficient. SACMI has been actively cooperating with Chinese users in the research and development of single-chip caps for hot filling, thus accelerating the process of single-chip caps into practical use

fashion choice of combination covers

people should still remember the scene that the sports cover of Nongfu mountain spring first appeared in China in 1998. Within three months, the sports cover on the market was overwhelming. With the integration of various cultures, it is inevitable that technological achievements will be displayed in a fashionable way. Therefore, the timely emergence of new combined covers similar to sports covers in the gradually fashionable Chinese beverage industry will make the variety of Chinese beverage covers more colorful and eye-catching
