50 Extrusion International 2/2025 QUALITY CONTROL – CASE STUDY Inline Measurement of Wall Thickness, Eccentricity and Diameter Wuxi Huacheng Cable Co., Ltd., based in Jiangyin City, is a specialist in manufacturing special high temperature resistant cables. The company relies on SIKORA’s X-RAY 6000 PRO to ensure optimal processes and the highest product quality. Since 2018, Huacheng Cable has used seven sets of SIKORA X-ray technology for quality control in seven new energy cable extrusion production lines that effectively leads to perfect monitoring and controlling of parameters of cable during the production. Q uality and performance requirements for new en- ergy cable are extremely high. All parameters, such as diameter, wall thickness and eccentricity must com- ply with speci cations. Several measuring methods for quality control are available on the market. Due to its functionality, however, SIKORA X-ray technology has proven itself as a leading method for measuring new energy cable. “With the X-RAY 6000 PRO we can use the full po- tential for process optimization and to deliver the highest product quality to our customers”, says Mr. Haihua Min, the general manager at Huacheng Cable. Directly integrated in the extrusion line the system al- lows to constantly monitor the wall thickness of up to three material layers and to reduce it to the minimum tolerance value. Safety margins can be successively reduced, and the automatic control keeps the dimen- sions within the speci cation. Quality control in combination with material savings leads to a signi cant increase in productivity. In addi - tion, by providing highest product quality, customer demands can be ful lled, and customer satisfaction is achieved.
