to customisation. Working with these types of enclosures to produce prototypes for testing, or for relatively low production runs, an enclosure supplier with CNC machining capabilities can provide a wide range of customisation services such as drilling, milling, cutting, and tapping. For example, Spelsberg UK’s engineering team customises enclosures to accommodate a wide variety of equipment, and to suit virtually any integration configuration. A prototype can be created in 24 hours, and a production run is potentially available within days.
THE MODULAR TOOL CONCEPT
OEMs with high-volume demands might require orders in the magnitude of thousands, and production runs of this scale outstretch the advantages of customisation with CNC machining. For high-volume customisation, the modular tool concept is better suited. With this approach, a tool can be developed to create design features specific to the requirements of the customer, with custom cut-outs or bespoke fastening
pre-embossing to create partially formed outlines such as knock-out guides that can be completed by the user during installation, through to completed cut outs of virtually any form. The modular tool service also includes embossing, including raised or recessed features in the enclosure such as internal or external mounting points. From the customer’s perspective, the quality of production and the timescale are virtually the same whether a modular tool or CNC machine is involved as a blended approach to bespoke production can be used. Flexibility and rapid availability are still achieved for high volume orders as an initial run of enclosures can be provided with Spelsberg UK’s on-site CNC machining service while modular tooling takes shape, which requires approximately four to six days. The reality is that the transition between on-site customisation and modular tool production is seamless.
points directly injected thanks to the modular tool, to efficiently manufacture at volume. Spelsberg’s modular tool production includes a variety of design options, from
ENCLOSURE ENGINEERING PARTNERSHIP With OEM production, cost management is always a priority. However, for volume orders, customers receive a customised enclosure for the price of a standard product. Even for smaller volumes requiring CNC machining, the cost is significantly lower than involving internal resources or working with a third-party engineering team. Sometimes, customisation of an existing enclosure design still does not cover requirements, even when modular tooling changes or CNC machining is involved. For the most specialised projects, Spelsberg can also design and manufacture completely bespoke housings from scratch, ensuring that even the most complex challenges can be resolved.
