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

Extrusion blow molding machine is one of the important equipment components of plastic hollow products. It can produce a variety of plastic blow molding products. In 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 extrusion blow molding machine generally need to control the wall thickness. There are two ways to control the wall thickness, regulating the parts of the blow molding machine and the parison wall thickness control device. These two methods will be described below. introduce.

The methods that can control the extrusion 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.

Our commonly used wall thickness control method is the wall thickness controller. This equipment is generally used to select a suitable controller for the production process during the design and production process of the extrusion blow molding machine, and then install it on the equipment. During the production process of the extrusion 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. The control and adjustment of the wall thickness are made in a shorter time, with high efficiency and energy saving.

The thick-wall 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.
