Extrusion International 3-2022

36 Extrusion International 3/2022 Measuring Technology T he SIKORA diameter gauge heads of the LASER Series 2000 and 6000 are versatile applicable in the line. In addition to the common wall thickness measure- ment after the vacuum tank, for example by SIKORA's X-RAY 6000 PRO X-ray device, another LASER gauge head can be installed at the end of the line where the tube or pipe is already crystallized. On the one hand, the diameter values of the cold measurement provide information about the shrinkage behavior of the tube respective pipe. On the other hand, an additional ovality measurement is thus realized. Furthermore, the tube or pipe surface is inspected for defects and protruding defects are reliably detected. This fnal quality control leads to the avoidance of com - plaints by the end customer. The combination with an ECOCONTROL 600 processor sys- tem (with 8.4'' touch screen) enables the measuring val- ues to be logged in detail at the end of the line. The installation of a LASER gauge head is thus an at- tractive option for tube and pipe manufacturers for a fnal quality control at the end of the line. Depending on customer requirements, SIKORA of- fers flexible solutions from 2 to 12 measuring axes. The SIKORA sales team has developed its own tool for this purpose, which calculates howmany measuring axes are required for a 100 % surface detection. In a customer meeting the calculation is done together to determine the best solution for the customer.

However, a new comparison of product parameters at the end of the extrusion line also offers tube and pipe manufacturers attractive advantages.
