Manufacturing of a Transmission Wire Harness Protection Sleeve for the Automotive Industry

An automotive industry client asked S&A Industries to produce a tubular heat protection sleeve to be used on a wire harness for a high volume automotive transmission application. S&A engineers assisted in the custom-design, then developed and built the automated tooling required to cut-notch, crimp, pierce and assemble an eyelet feature for securing the sleeve to the wire harness. The S&A team also validated the thermal effectiveness of the sleeve in accordance to SAE J2302.The composite assembly featured a combination of non-woven insulating materials and highly reflective aluminum foils. The wire harness maintained a temperature of under 125°C when in operation just 150 mm from the 550°C heat source. Online automated inspection ensured the finished product complied with the customer-supplied specifications. For details, please see below .
