On extrusion lines, even a slight dimensional deviation, eccentricity, or surface lump/depression defect can increase scrap rates or lead to customer complaints.

Building on years of R&D and industrial application experience in laser diameter measurement, length measurement, and wire-drawing die inspection, DALA Metrology offers a line-wide Full-Process Quality Inspection Solution for Extruded Wire & Cable, delivering reliable, stable, and efficient in-line quality control for manufacturers of metal wire, electrical wire, cable, and related products.

One Solution, Full Closed-Loop Inspection

DALA’s extrusion-line solution creates a closed-loop inspection process across the hot end, cold end, and end of line:

01 Bare Wire / Hot-End In-Line Diameter Measurement

02 Cold-End Eccentricity & Comprehensive Defect Inspection

Eccentricity + Lumps/Depressions + Dimensions in One System

The EF Series non-contact cable eccentricity gauge is designed for precision measurement of eccentricity, wall thickness, diameter, and ovality, while also enabling high-speed detection of surface lumps and depressions. Deployed during cooling and take-up, it captures eccentricity trends, surface irregularities, and local bulges or dents in real time—helping operators detect, locate, and address defects earlier to significantly reduce scrap.

03 Surface / Insulation Defect Inspection

New In-Line Spark Tester

DALA’s new-generation spark tester helps verify insulation integrity by detecting pinholes, thin spots, and other defects in time to prevent nonconforming products from moving downstream. On high-speed lines, it supports defect positioning and classification, providing data for downstream rejection or marking.
