Lump & Neckdown Detector

Say goodbye to laser gauges.

The Lump and Neck-Down Inspector is the only tool that can provide images of your lumps and neck-downs on: cable jacket, pipe or tube. This is critical in assessing whether a measured diameter variation is in fact a defect and whether action must be taken. Your technical staff won’t have to rewind miles of product to try to locate a defect. They can use Taymer’s image viewing software to analyze and diagnose any detected defects.

Accurate, Multi Axis Diameter Measurement

The Lump and Neck-Down Inspector also provides you with very accurate, Multi-Axis diameter measurements. This diameter information can be integrated with other machinery in your line for complete automation of your line processes. The Lump and Neck-Down Inspector’s display also makes it easy for engineering and production supervisors to examine the outer surface of your product as it is being extruded.

Quality Assurance

The Lump and Neck-Down Inspector will capture images of your cable defects, save them to disk so you can print them out to include in your quality reporting both internally and to your customers. Defect locations are recorded together with the image of the defect allowing your operators to find and eliminate lumps and neck downs before they reach your customers or fail in the field. With Taymer’s Lump and Neck-Down Inspector, you can be sure the product going to your customers meets your high standards.
