Background

The injection-blowing filling-sealing four-in-one machine is a special mechanical device, and mainly adopts a mode of curing and double-layer secondary processing after the core is cured in the production of the core shooting machine and then enters a compound die. In short, the machine is suitable for high-speed continuous production, and can meet the requirements of producing high-precision and high-quality plastic products. Before the plastic product is subjected to a bottle blowing link, the plastic product is subjected to temperature-adjusting pre-blowing, and the temperature-adjusting pre-blowing link mainly aims at ensuring the quality and the production efficiency of the plastic product.
