Extruded Seal Deflection, Insertion and Extraction Forces

Specification

Vintech Industries Inc. is a global tier 2 supplier of thermoplastic extrusion components to the automotive and non-auto RV industry. Internationally renowned OEM brands specify Vintech’s weatherstrips, seals and gimps as original equipment for glass, trim and closure sealing. Committed to continuous improvement and the production of defect-free parts, on time, the company’s Quality Control division tests to strict automotive industry standards, including GMW14685 and GMW14712. To further improve the performance of their co-extruded designs, Vintech moved to bring the testing processes in-house. This investment not only increased efficiency through reduced outsourcing costs, but most importantly brought faster turnaround times in design iterations for their customers, increased opportunities to win new customers, and added the capability to perform other tests to its own internal specifications—functions previously outsourced to material suppliers.

Complete solution: testing requirement, fixture design, results reporting to Vintech’s customers

To cover the variety of testing procedures, Mecmesin supplied a 2.5 kN computer-controlled single-column test stand with a range of grips and fixtures, a portable, 500 N digital force gauge and a selection of compression plates. Engineers from both companies worked on the specific requirements to provide a comprehensive suite of solutions, from custom fixturing—conveniently interchangeable on standard mounts—through to professional reporting back to the OEM client. EmperorTM software enables the accurate control of the test procedure, data acquisition and analysis of the results for a host of test methods dependent upon the part’s functionality and movement. Amongst the growing library of programs are compressibility of elastomeric components, to ensure effective sealing forces in vehicle closure systems, plus insertion and extraction forces of moldings to meet manufacturing ease-of-assembly and replacement—yet secure retention in service.
