Hollow blow molding machine is one of the important equipment parts 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 problem, so today we will understand how to control the wall thickness problem together. .

The products produced by hollow blow molding machines generally have to control the wall thickness. There are two methods to control the wall thickness, which are the control devices of the blow molding machine parts and the parison wall thickness control.

The way to control the hollow blow molding machine equipment is to adjust the head gap, flow rate, and head temperature of the equipment to control the thickness of the output product.

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

Our commonly used wall thickness control method is a wall thickness controller. The equipment is generally designed to select a suitable controller during the production process of the hollow blow molding machine, and then install it on the equipment. During the production process of the hollow blow molding machine, The combined equipment controls and adjusts the wall thickness of the product together.

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

The thick-wall controller uses point-to-point control, that is, 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 is divided into multiple points. Click to control, narrow the control range, and achieve better control effect.
