How to control the wall thickness of the extrusion blow molding machine

The hollow blow molding machine is one of the important equipment components of plastic hollow products. It can produce a variety of plastic blow molding products. During the production process, some products need to control the wall thickness, so today we will learn about how to control the wall thickness. .

The products produced by using the hollow blow molding machine generally need to control the wall thickness. There are two ways to control the wall thickness. The parts of the blow molding machine and the parison wall thickness control device are controlled. These two methods will be described below. introduce.

The methods that can control the hollow blow molding machine equipment include adjusting the head gap, flow rate, and head temperature of the equipment, so as to control the thickness of the output product.

How to control the wall thickness of the extrusion blow molding machine?

Our commonly used wall thickness control method is the wall thickness controller. This equipment is generally used in the design and production process of the hollow blow molding machine to select the appropriate controller for the production process, and then install it on the equipment. During the production process of the hollow blow molding machine, Combined equipment to control and adjust the wall thickness of the product.

As for the wall thickness controller, when some hollow forming equipment with complex cross-sections is produced, the adjustment effect of the wall thickness controller will be more scarce and timely than the control of temperature and flow rate. At the same time, it can also be designed according to the parameters of the process and equipment. The control and adjustment of the wall thickness are made in a shorter time, with high efficiency and energy saving.

The thick-walled controller uses the control to use the point control, that is, after the plastic raw material is melted into a molten state, in the process of extruding through the die to form the parison, on the parison, it is divided into multiple points, respectively for each one. Click to control, narrow the control range, and achieve better control effect.
