Parison control

The task of Parison control is to adjust the thickness of different parts of the product wall. The operation method is that the signals received from the LVDT along with the thickness value set by the device panel are issued as a command to the hydraulic valve. Then, using the programming done in the thickness board (PID controller), different parts of the product wall are controlled.

What does controlling the wall thickness of the product mean?

Parison control or parison means dynamic control of parison thickness to obtain a container with uniform thickness in air plastic machine. The control parison helps maintain the required thickness axially and radially on an extrusion/injection blow molded (BM) product.

Why should we control the wall thickness of the product?

The wall thickness of blow molding products is also the main factor for quality measurement. Therefore, during the production process, to ensure the quality of the molding products, it is necessary to evaluate the wall thickness with high accuracy and the tracking response speed to be fast enough.

Parison control of the extrusion machine

Parison Control is used in various industries, including plastic injection and molding industry, where there is a need to check a nozzle by hydraulic valves in a closed loop (with the ability to receive commands in digital or analog form).
