Twenty-five years ago, Liberty Electronics’ system for creating and distributing work instructions was 100% paper-based. At Liberty, as with most companies in the industry at that time, engineers created work instructions for each assembly, printed out each document, and distributed them to manufacturing personnel. These manufacturing employees, in turn, depended on these paper documents in order to assemble components according to contract. Upon completion of an order, the documents often had to be filed for reuse at a later time.
Original equipment manufacturers (OEMS) in the aerospace and military defense industries rely on efficient integration of many different parts with little margin for error. As a result, effective aerospace and military manufacturing relies heavily on maintaining good business relationships between different buyers and suppliers on the production chain.
Creating a quality product doesn’t just end with the manufacturing phase. Choosing the best packaging and shipping options to meet a client’s needs is also an important step in ensuring a product reaches the client in the same state it left the facility. Components are packaged according to specific standards and or client guidelines, and these may include special instructions or specifications, as well as quality assurance measures taken during the manufacturing and packaging process. A variety of packaging options can be used to achieve this goal, including ESD packaging and 3D-printed covers, as well as other more traditional packing products.
Strategic sourcing processes allow manufacturers to choose the best vendors based on more factors than cost alone. By evaluating other characteristics such as quality management practices, efficient operations, design capabilities, and sustainability, purchasing managers are using strategic sourcing techniques to look at the “bigger picture” for long-term growth.
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.
This November, Liberty Electronics will celebrate five years since producing its first in-house 3D printed part in 2013. The company added two additional 3D printers to its roster in 2016, another this month, and is looking ahead at the possibility of adding metal-capable machines in the future. The implementation of additive manufacturing has proven to be incredibly successful for the company and has continued to set Liberty apart as a versatile innovator in the industry.
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)
