Elaplus Case Study on Fixing Wiring Harness of Electric Tool Control Board

In the electric tool industry, the fixing and bonding of control board wiring harnesses are important links to ensure equipment stability and safety. The wire harness needs to withstand severe tests such as long-term vibration, mechanical impact, and environmental temperature and humidity changes, so choosing the appropriate adhesive is particularly crucial. Elaplus provided customers with PUR 1603 two-component solvent-free adhesive, helping them solve multiple challenges in fixing control board wiring harnesses. This article will share in detail this case, analyzing customer needs and how Elaplus provides ideal solutions for customers through PUR 1603. Case background: Fixed requirements for wire harness of power tool control boardThe client is a well-known power tool manufacturer specializing in the development of high-performance power tools and their accessories. The control board wiring harness typically needs to withstand complex working environments inside electric tools, including high-frequency vibrations, temperature fluctuations, and exposure to chemicals. Therefore, the customer has put forward the following key requirements for the adhesive fixation of the control board harness:After curing, the hardness is high, ranging from 50-70D: Due to the significant mechanical impact experienced by electric tools during operation, customers require the adhesive to be cured to achieve sufficient hardness and provide sufficient support to ensure that the wiring harness is not loose.Good adhesion performance of silicone wire: Silicone wire is often used as an insulation material for cables in electric tools, so when bonding silicone wire, the adhesive needs to have good adhesion.Room temperature curing: The customer hopes that the adhesive can be cured at room temperature to simplify the production process and improve production efficiency.Solution: PUR 1603 two-component adhesivePUR 1603 A/B is a two-component solvent-free room temperature curing adhesive. Low odor, low VOC, compliant with ROHS and REACH regulations. Wide process operability, high physical properties of finished products, suitable for machine…
