    E-Fab is a Critical Manufacturer per Homeland Security Guidelines

     

    Dear E-Fab Customers,

    With the Coronavirus (COVID-19) situation developing quickly, we believe it is important to keep our customers informed. We want to let you know we are open for business. E-Fab Inc. serves customers involved in Communications, Military, and Health-Care industries, which are all considered “Essential Activities”.

    Appropriate measures have been taken to ensure the health and safety of our employees and their families, which is of utmost importance. We have implemented steps to avoid disruptions in service by:

    • Educating our staff on virus prevention and protection
    • Providing face masks, cleansers, and sanitizers to all employees
    • Securing our buildings to include employees only
    • Daily and thorough disinfecting procedures for each department
    • Working from home where possible and production/shipping/receiving departments have enlisted working in shifts
    • Efficiently using cross-trained employees.

    We have also reached out to our suppliers and, to date, we do not anticipate any delays. There may be a slight disruption with our vendors whom we use for secondary operations such as Plating, Cleanroom packaging, and Heat-Treating. If your parts require Etching only, we do not anticipate any delay in shipment. However, if the parts require secondary operations as listed above there could be a delay. We will keep you informed, remain in constant contact, and will continue to monitor our supply chain accordingly. We greatly appreciate your business and remain committed to providing the exceptional service and quality you have come to expect from E-Fab Inc.

    We continue to monitor the situation closely and will keep you posted on any changes. Stay Safe and Healthy! Together we will overcome this crisis!!

    Regards,

    E-Fab Inc.

  2. Is Photochemical Machining (PCM) Right For You? Yes!

    Comments Off on Is Photochemical Machining (PCM) Right For You? Yes!

    The Basics of Photochemical Machining (PCM)

    Photochemical machining (PCM) is an excellent alternative to traditional CNC machining operations. Thousands or millions of high precision parts can be manufactured at one time with substantially reduced tooling costs. Metal parts that are intricate in nature, with complex shapes and geometries, can easily be tooled using CAD/CAM software and printed on a phototool. This minimizes expensive mechanical and manual operation costs and reduces the overall turnaround time.

    We know that our customers want quality parts machined to specifications, with on-time delivery, and at the agreed-upon pricing. E-Fab engineers ensure that the processes used are in the best interest of getting you what you want. Whether this is a one-off prototype run or a multi-million production run, we are able to keep costs low and quality high.

    PCM Process

    1. Create Phototool – a component containing a negative image of the desired part used to block UV light from reaching specific sections of the workpiece
    2. Prep Metal – cutting, cleaning, and applying photoresist—a light-sensitive compound—to the sheet metal
    3. Exposing – applying UV light to the masked metal, which hardens the exposed photoresist
    4. Developing – washing off the unhardened photoresist to reveal raw metal
    5. Etching – specialized etching equipment and etchant removes the unprotected raw metal areas
    6. Cleaning – removing the remaining photoresist to reveal the finished part

    PCM Advantages

    Tolerances Photochemical machining (PCM), or photo etching, is ideally suited for most metals and alloys that are less than .050″ in material thickness depending on features and part tolerances. Parts requiring tighter tolerances can be easily stepped and repeated on larger panel sizes with high parts to panel density ratios. This substantially increases the yield ratio and decreases the material waste.

    Low Cost – Traditionally, CNC machining and milling have difficulty making thin metal parts. PCM can solve the complex thin metal part challenges, and at a fraction of the cost. E-Fab can beat the cost, time, and accuracy of traditional manufacturing methods like CNC turning, milling, laser cutting, waterjet, and wire EDM (electrical discharge machining).

    Quick Turnaround Engineering modifications can be done quickly and conveniently using CAD/CAM software. PCM allows the designer and engineer to significantly reduce the turnaround time involved with prototypes and improve the complete production time frame.

    Part Integrity The PCM process maintains surface quality without producing burring or tool markings as with CNC machining. Metal properties and structural integrity of the alloys are also sustained through the process.

    E-Fab PCM Applications

    Metals – The PCM process is well suited for manufacturing thin metal parts in a variety of metals including aluminum, beryllium copper, brass, bronze, copper, Kovar, molybdenum, nickel, nickel silver, spring steel, stainless steel, steel, tin, and other common and exotic materials.

    Products – With the design freedom of PCM, nearly any part can be made. E-Fab manufactures custom parts to customer specification, some of which had included stiffeners, busbars, flex circuits, mesh screens, antennas, micro bumps, connectors, contacts, filters, gaskets, heatsinks, lids, masks, RF circuits, sensors, shields (EMI/RFI/RF), shims, spacers, springs, step lids, and washers. The list is endless.

    Industries – E-Fab has had a long history of working closely with the military and many leading aerospace companies. We provide engineering, design, and technical support services for all types of applications for aerospace, defense, medical, aviation, electronics, laser technology, semiconductor, automotive, pharma/biotechnology, and renewable energy.

    Secondary Services – We not only want to provide thin metal etched parts, but we want them to be completed per your final needs. To get the parts from etched to application ready, E-Fab offers additional services including forming, shaping, bending, CNC machining,
