Control System
Multistage Extrusion Line Control System
Increased automobile manufacturers requirements to car part quality with regard to precision fitting, product characteristics and safety features have increased requirements to the machines and production lines needed to manufacture these components with regard to precision and uniformity.
Multistep Extrusion Line Control (MELC)
Function Elements
In a series of tests carried out under production conditions, irregularities could be reduced by more than 50 % for the mentioned quality characteristics.
An additional desirable effect was that profiles manufactured with this control system held uniformity for a longer period of time when emptying the extruders e.g. during change of extrusion material.
Especially if frequent change of material is required, this will noticeably reduce scrap material and increase productivity of the extrusion line.
The system is not exclusively available for new extrusion lines, a retrofitting kit makes it easy to mount the system in existing production facilities as well.
The system, for which patents have been applied for, is suitable for multi-component extrusion lines with up to four extruders operating on a multicomponent extrusion head.
