A blow molding machine mainly consists of five parts: a feeding system, a heating system, a blow molding system, an unloading system, and a control system.
Blow molding machines are key equipment in modern plastic bottle production. Their efficient and precise workflow benefits from the close cooperation of each component. Below, we will take a closer look at each part of a blow molding machine.
Material Feeding System
The material feeding system is the starting point of the blow molding machine, primarily responsible for conveying the plastic raw material to the heating system at a stable speed and pressure. This system typically consists of a hopper, screw, and conveying pipes, ensuring a uniform supply of raw material and laying the foundation for subsequent heating and molding processes.
Heating System
The heating system is a crucial component of the blow molding machine, its function being to heat the plastic raw material to a suitable softening temperature. This system usually consists of multiple heaters, precisely controlling temperature and time to achieve the ideal plasticization state of the raw material, facilitating subsequent blow molding.
Blow Molding System
The blow molding system is the core of the blow molding machine, responsible for blowing the heated plastic raw material into a bottle shape. This process includes multiple steps such as mold closing, controlling the blowing pressure, and setting the molding time. The precision and stability of the blow molding system directly affect the quality and yield of the final product.
Removal System
The removal system is responsible for removing the molded plastic bottles from the mold and performing necessary cooling and shaping processes. This system typically consists of a robotic arm and a cooling device, which can efficiently complete tasks such as bottle picking, cooling, and shaping to ensure the smooth production of the product.
