The trend of the semi-automatic five liter bottle blowing machine market is moving towards high-speed and fully automatic direction. High speed fully automatic bottle blowing machines can greatly liberate productivity and improve production efficiency. On the other hand, with the high degree of automation of other production lines such as filling machines, only high-speed fully automatic bottle blowing machines can fully match modern production lines. Under such market trends, many manufacturers in the bottle blowing machine industry have announced full automation. However, the author believes that although the general trend is towards full automation, the special situation of the downstream market cannot be ignored. We all know that the production and processing of plastic bottles is a relatively low profit and low entry threshold field. This has led to the concentration of a large number of small and medium-sized plastic bottle manufacturers in the field of plastic bottle processing, some of which are even family workshops. For these small processing plants, the high equipment cost of high-speed fully automatic bottle blowing machines can be said to be difficult for them to afford. These companies are more willing and suitable to purchase semi-automatic or simple bottle blowing machines. As a blow molding machine manufacturer, when developing products towards full automation, we should also take into account this market and continuously adjust and improve the production of simple and semi-automatic blow molding machines. Nowadays, in the fierce competition, the price of fully automatic bottle blowing machines is getting lower and lower. The bottle blowing machine market not only looks at trends, but also considers various factors in order to be more stable.
