The first way is more common, there are different grades of equipment and molds to choose from, and the low-end ones are very cheap. It is said that small workshops can make hundreds of cold runners, but. High-end injection molding machines and molds are also called gland systems. If the domestic injection molding machine can mold about 5 million sets of 48 cavities (high-speed injection molding machine and high-efficiency hot runner molding die), the shortest cycle of the current water bottle cap 2925 can reach 1.85 seconds/die (exhibited by manufacturers in Shanghai in April this year), and the domestic mold is currently more than 3 seconds/die.
The second type of continuous molding machine, commonly known as bottle cap machine, has much less choice. At present, Scami is the only high-end product, and there are some cottage products in China. Scami machine-equipped mold, the cavity is about 30 thousand.
