Laser Compression Deformation Tester，Laser deformation measurement system
The Laser Compression Deformation Tester for sealing strips is designed for automotive sealing strips to precisely measure compression deformation and residual deformation. Using non-contact laser scanning technology, it captures linear compression curves with high accuracy and repeatability. The system evaluates elastic sealing strips throughout compression and release, generating quantitative data for quality control and R&D analysis.
Application
(1) Automotive sealing strip testing: door, window, trunk, and hood seals compression and permanent deformation evaluation.
(2) Automotive elastomer components: seals, vibration dampers, and elastic parts long-term compression performance testing.
(3) R&D and quality control: new material development, material selection, and batch consistency verification.
(4) Automotive supply chain: supplier quality inspection to ensure compliance.
(5) Environmental simulation: combined with temperature and humidity testing for deformation behavior under various conditions.
(6) Industrial rubber products: applicable to other elastic rubber profiles beyond automotive seals.
Standards
(1) GB/T 7759-2008: Determination of compression set of rubber and rubber products.
(2) GB/T 21282-2007: Compression performance testing for automotive rubber seals.
(3) QC/T 709-2007: Automotive rubber seal compression performance test specification.
(4) VW PV 3363: Determination of permanent deformation of automotive sealing strips.
(5) SMTC 3 C00003-2010: Sealing strip compression performance test.
