Precision Processes

Splices / Solder Joints are common in the construction of wire harnesses.  Producing a quality splice is essential as they are embedded within a harness and most of the time are very difficult to access once the harness is installed.  We construct splices using thru-splice equipment, but we also have the capability of performing ultrasonic welds.

Martin Interconnect has produced harnesses with numerous styles of coverings. Overbraiding is utilized in many applications and results in a harness that is abrasion resistant, doesn’t hold moisture and produces a smaller diameter bundle than split loom. Also, due to the special equipment required, harnesses are tamperproof. The yarn used in the process is flame retardant as well.
