Heat shrink tubing lead-in section: Heat shrink tubing is applied to the wires, typically to protect splices and crimp areas (especially on wires with larger cross-sections). This type of section is simpler than others and the operations to be performed are very simple but must be done with care so as not to damage the equipment area. The operator threads the tube through the wire/connector and places it on top of the heat blower while rotating the assembly to evenly distribute the heat.
Before validating the use of a component that will be part of a wiring harness, the manufacturer performs the necessary tests to determine whether the component meets the required quality standards. Testing takes place in the Test Center, an area specially designed for the purpose, where wires, splices and crimp terminal-wire combinations are tested for durability against various aggressive factors.
Types of tests performed in the test center: drag chain test, torsional action test, bending test, burning test, media resistance test.
At the beginning of each production cycle, a representative sample of the splice (ultrasonic welding) and crimp terminal wire is subjected to durability testing and microscopic quality inspection to ensure that the parameters set for semi-automatic and fully automatic machines are consistent. required quality standards.
