All Fibox enclosures can be customized to meet your application’s requirements. Sophisticated CNC machinery can fabricate enclosures with holes, cutouts, recesses, and more. Enclosures can be laser printed with nomenclature, photo quality images and text. Any accessories can be installed…resulting in delivery of a completed mechanical assembly. At our Baltimore service center, FiboxUSA maintains a customization facility, staffed with application engineers, CAD and CAM programmers, and equipped with modern CNC machinery specifically designed and built for precision plastic machining. Many packaging solutions utilize Fibox accessories to improve the functionality of the enclosure system. Fibox can provide assembly services and install accessories specified by the end user, allowing delivery of “ready to use” mechanical packaging assemblies, saving labor and speeding manufacturing. The Fibox accessory program includes a large number of items ranging from hinges and latches, cable glands and wiring accessories, to inspection windows and ventilators.For the customer requiring modification of a Fibox standard enclosure, CAD drawing files are available for use with all major computer design programs. Factory technical assistance is available to help the engineer create the most cost-effective customized enclosure that will meet his needs.
Enclosure Customization Pointers
Customization impact on enclosure selection. Enclosure size, the operating environment, and the NEMA rating make up the main criteria for selecting an enclosure. Within Fibox’s wide range of product, you may find even more than one enclosure choice or you may narrow your selection based on your required features. For example, a cable gland may be needed for wire entry. If a threaded mounting hole is required, a thin wall enclosure may not be suitable for threading and a thicker wall (e.g. 3 mm) enclosure should be selected. If you are unsure of your enclosure selection or the impact of desired modifications, please contact our applications staff. Fibox can guide your enclosure selection and at the same time suggest cost effective customization methods.
Factors impacting cost – After the enclosure, many items can affect cost. From the beginning design phase, Fibox will work with you to advise how to reduce costs. There may be a one time engineering charge to review the design and to program our CNC machinery. As well, usually there is a cost required to set up the CNC machine which is a recurring cost with each machining run of enclosures. Of course, the actual modifications also affect cost. A large cutout for a DIN meter is typically more expensive than a small round hole. A milled recess is more expensive than an open slot. The total time to machine the modification determines the cost.
One of the more significant cost drivers is the number of enclosure sides being modified, because each side requires its own program and each side requires set-up. For example, two holes on each of two sides will be more costly than four holes on one side. Also, the cover, lid, or door is a separate part, requiring a separate set-up and program. The designer can control cost by understanding that different machining operations may require different tools.
Tool changes, even when automatically done, require time , effecting throughput. And, more time equals more money. In many cases a simple design change can minimize tool changes. For example, does that cutout corner radius really need to be 1 mm, or can it be 1.5 mm? Fibox personnel will review your design and offer suggestions to reduce cost.
Tight tolerances can be achieved in machining holes and hole pattern relationships, but specifying excessively tight tolerances will increase the cost. The repeatability of machined patterns, unit to unit, is excellent, but the nature of plastic means that overall enclosure dimensions may slightly change due to molding process variations. Dimensioning to piece part centerlines and mold parting lines minimizes the impact of these variations, and results in lower overall cost. Fibox staff is ready to assist with your specification.
Documenting the design – Ideally, the designer should provide Fibox with a computer-aided design (CAD) file indicating the modifications. Fibox provides CAD files of their enclosures, and these should be used by the designer as his starting point. This ensures dimensional accuracy and simplifies drawing interpretation. While a CAD file is ideal, Fibox can work with just about anything. However, additional drawing costs may result. Using Fibox’s CAD files during your design will speed the process and lower your overall costs.
Economies of scale – Larger production runs can lower costs, but only up to a point. Ideally, one wants to have a large enough production run to minimize the impact of set-up costs. Customization with CNC machinery is cost effective up to single runs of 1000 pieces. If larger volumes are required, Fibox can more cost effectively supply them using customized molding based upon standard enclosures. The cost for custom modifications of a standard mold is usually much less than the cost of an entirely new injection mold.
Now, more than ever, plastic enclosures offer cost effective value for customized electronics packaging. Specialized CNC machines permit enclosure manufacturers to offer extensive customization services at lower cost and faster turn around times. Then when the volume really takes off, plastic permits easy ramp-up by substituting customized molding for CNC customization. With a basic understanding of the process and the input required, the design engineer can now obtain the most cost effective solution for all ranges of piece part volume.
