Compression molding caps replace injection molding caps Although compression molding is a new process that has only appeared in the past 20 years, due to its characteristics of power saving, beauty, and high efficiency, it has issued a strong challenge to the century-old traditional injection molding process and has obtained an overwhelming advantage. At present, the market share occupied by compression molded caps is getting higher and higher. Coca-Cola, Pepsi, Uni-President, Master Kong, Wahaha, and Huiyuan have all switched to compression-molded lids. Since 2001, the number of Chinese customers buying compression molding equipment has greatly exceeded that of injection molding equipment.
The development direction of plastic anti-theft bottle caps
The application of single-piece caps and short caps has gradually increased. Since 2002, the price of petrochemical raw materials has generally increased worldwide, while the price of caps has dropped instead. Therefore, people are more stimulated to seek newer technologies to reduce costs. In order to better reduce the cost, people focus on the PET bottle mouth, and shortening the bottle mouth has become their favorable measure. Coca-Cola first implemented the 1881 bottle mouth standard in China, and the application of monolithic caps and 1881 bottle caps gradually increased.
