How to adjust the wall thickness control of the hollow blow molding machine
Hollow blow molding machine is one of the primary equipment for the production of hollow plastic products. The wall thickness control problem during the production process has always existed. How to adjust the wall thickness of the hollow blow molding machine brought to us today gives us different wall thickness control solutions. Trust will definitely help us.
Hollow blow molding machine equipment is first of all the wall thickness control adjustment method for hollow blow molding machine equipment: the wall thickness control of the produced products can be completed by adjusting the head gap, flow rate, and head temperature of the equipment. The second is to choose some external cooperation methods.
What we often use is the wall thickness controller. This equipment is generally used in the design and production process of the hollow blow molding machine. According to the practical production process, the appropriate wall thickness controller is selected, installed on the equipment, and blow molded in the hollow blow molding machine. During the production process of the machine, the cooperative equipment controls and adjusts the wall thickness of the product.
Compared with the first method, the adjustment effect of the wall thickness controller will be more accurate and timely. It can be controlled and adjusted in time according to the actual production process and the setting of equipment parameters. It takes a short time, high efficiency, and energy saving. it is good.
The wall thickness controller selected for the hollow blow molding machine uses a control technology that is controlled at points during the processing of the preform. The so-called sub-point control means that after the plastic raw materials are melted into a molten state, they are extruded through the die to form a parison. The parison is divided into multiple points, and each point is controlled separately to reduce the size. Control range to achieve better control effect.
