  • Detail

Pressing plastic cap is the inevitable core technology of beverage packaging.

since the mid-1990s, the plastic anti-theft cap has been used to replace the aluminum cap for PET bottled beverages produced by Coca Cola, thus pushing the plastic anti-theft cap to the front stage of beverage packaging. Since then, powerful domestic packaging enterprises and beverage manufacturers with a range of 0 ~ 10 mm have introduced foreign equipment, becoming a new material industry base with great influence in the province, and started 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 adopting the latest production processes and equipment, making China's capping machinery and plastic lid production technology level with the world's advanced level. For example, SACMI, Alcoa, husky, Demag, nestal, Engel and other world-famous capping machines have entered China

at the same time, in the field of plastic bottle cap production, the policy of coal and steel capacity reduction for injection molding and compression molding industry has taken effect rapidly, and the debate on technology has also begun. Undoubtedly, technological innovation is the driving force of development and progress

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

the pressure plastic process is very simple. The quantitative materials are put into the upper and lower molds, and the upper and lower molds are closed, that is, the materials are processed, then cooled, demoulded, and the cap making is completed. The injection molding process is like injection. The material is pushed to the gap of the mold until the gap is filled, and then cooled and demoulded 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 presents a powerful challenge to the 100 year old tradition of injectionmolding (IM). In terms of comprehensive cost from the perspective of energy consumption, material consumption and environmental protection, there is no need to discharge in the beverage industry, and pressure plastic capping is undoubtedly the development direction of capping methods at present and in the future

at present, the pressed plastic covers account for more than 80% of Coca Cola, Pepsi Cola, uni president and Master Kong; Wahaha's tea drinks, soft drinks and Huiyuan pet juice 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, 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 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 speeding up the process of single-chip caps into practical use

fashion choices for combination covers

people should still remember that the sports covers of Nongfu mountain spring first appeared in China in 1998. Within three months, the sports covers on the market were overwhelming. With the integration of various cultures, it is inevitable that technological achievements will be displayed in a fashionable way. Therefore, the timely appearance 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
