Pressing plastic caps has become the direction of technological innovation of plastic bottle caps for beverages.
since the mid-1990s, plastic anti-theft caps have been used to replace aluminum caps for PET bottled beverages produced by Coca Cola, thus pushing the plastic anti-theft caps to the front stage of beverage packaging. After this hydraulic system is easy to cause oil heating, domestic powerful 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 adopting the latest production processes and equipment, which will further expand the popularity of China's capping machinery and plastic products, and the production technology level of capping materials will reach 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 and demoulding are completed to complete cap making. The capping process of injection molding 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 capping
continuouscom pressonmolding (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). Considering the comprehensive cost from the perspective of energy consumption, material consumption and environmental protection, in the beverage industry, pressure plastic capping is undoubtedly the development direction of capping methods at present 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 adopted price reduction and various preferential promotions, the development trend of cover making by compression molding process has not decreased. Since 2001, Chinese customers have purchased a number of compression molding equipment. D) conditions save leather belt composites, plastic profiles, waterproof coiled materials, steel pipes, copper, profiles, tension spring steel, bearing steel, stainless steel (and other high hardness steel), castings, steel plates, steel strips, non-ferrous metal wires, etc.: experimental control data and sample conditions can be made into modules, which greatly exceeds the amount of 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
