Elaplus Case Study on Potting of Electronic Lock Wiring Harness for Automotive Parts

In the modern automotive manufacturing process, the stability and reliability of automotive electronic systems play a crucial role in the overall performance of the vehicle. Especially in the application of electronic lock systems, the safety and durability of wiring harnesses are one of the core elements to ensure the normal operation of automobiles. In this field, Elaplus’ high-performance potting adhesive products have achieved significant results in the application of automotive electronic components, especially in the potting protection of electronic lock wiring harnesses. This article will provide a detailed introduction to the solution provided by Yilian for the sealing of automotive electronic lock wire harnesses and the recommended product used – SIPC 9400. Background and ChallengesWith the acceleration of automotive electronicization, electronic lock wiring harness, as an important component of automotive electronic systems, has increasingly strict performance requirements. The electronic lock harness not only needs to withstand harsh working environments, but also must ensure that there are no electrical faults, circuit damage, or short circuits caused by external environmental changes during long-term use.One of the biggest challenges for the encapsulation protection of electronic lock wiring harnesses is selecting suitable adhesive sealing materials. The specific requirements are as follows:▶ Material compatibility: Electronic lock wiring harnesses are usually composed of PVC wiring harnesses and PA66+30% GF (reinforced polyamide) materials. How to choose the appropriate sealant for these two materials and ensure good adhesion between the materials is the key to this project.▶ Hardness requirement: The hardness of the cured sealant should be moderate, neither too hard to cause brittle cracking nor too soft to affect the protective effect.▶ Pull test requirements: After the adhesive is cured, it must be ensured that the outer skin of the wire harness is not damaged during the pull test to meet the durability and safety standards of…
