Braided coverings and shieldings are an excellent way to make wiring configurations neat and uniform. Braiding gives wires more flexibility and a longer lifespan and can also offer a layer of electric protection or abrasion resistance. Although there are two different types of wire braiding widely used in the industry, machine braiding and premade (or slide-on) braiding, machine braiding offers more versatility, cost savings, and consistency, and should be something a contract manufacturing partner should be able to do in-house.
Recently, the Washington Metro Area Transit Authority (WMATA) in the nation’s capital was forced to decommission nearly 75% of its new 7000-series rail cars due to crimping defects. The rail cars had crimping defects that went undetected until WMATA’s quality inspectors discovered them. The WMATA’s Quality Assurance, Internal Compliance and Oversight office (QICO), estimates that the rail cars will take over a year to be repaired. Going forward, QICO is requiring that in-process quality checks and high standards of engineering design be more explicitly outlined in WMATA’s manufacturing contracts.(1)
