    3D Printing and Rapid Prototyping

    3D printing and rapid prototype service allows cost effective prototype development. Ideal for development production capable of up to 100 off runs, the 3D printed parts can be made in a range of polymers including ABS and polypropylene, as well as specialist conductive plastics.  Added EMI shielding protection can also be applied in the form of our anti static/conductive or shielding paints.

Working with the customer, Shielding Solutions offers a full design service.  Once approved, Shielding Solutions will 3D print the design enabling the customer to trial his prototype product prior to committing to expensive metal machining or moulding. Boxes, enclosure, or indeed any other plastic part can be 3D printed offering the customer low cost, small runs, negating the use of expensive traditional tooling which also demands high minimum run quantities. The simplest and quickest method to get your design 3D printed is to send us your 3D model file which we can then convert and load into our systems.

  • Can be fitted to EMI and environmental gaskets to prevent over-compression or the distortion of mating surfaces with the aim of limitinggasket compressionto between 10% and 20%.

    Compression Stops and Collars for Gaskets

    We stock a range of compression stops and collars for EMI and environmental gaskets. Limit stops and collars can be fitted to EMI and environmental gaskets prevent over-compression or the distortion of mating surfaces. With surface mounted EMI and environmental gaskets, the aim should be to limit the compression of the gasket to between 10% and 20%. 10% being the minimum with a solid silicone style of gasket. This means some form of compression stop or limit is essential with surface mounted gaskets to prevent over compression. Compression stops can be built into many styles of gasket, or made as an integral part of the flange. Their height should equal that of the maximum compressed height of the gasket. Compression stops fitted into gaskets can be in the form of collars or washers so that fixing bolts can pass through them or as solid studs located either side of a fixing bolt. The thickness of the gasket for a known application can be calculated as follows e.g. Consider a gasket which can be compressed between 10% and 25% to be used on flanges which are not perfectly flat, i.e. the flanges without gaskets touch at some points and leave gaps in others. Since the gasket will compress between 10% and 25% we will require 25% compression at the high points and 10% at the low points (the “gaps”). The greatest gap is therefore 15% of the gasket thickness. If that gap is 0.45mm, then a gasket of 3.0mm thickness is required This is fine in theory provided that the flanges do not “bow” when placed under load. To overcome flange distortion, fixings may need to be added, the number of which will be determined by the flange stiffness/rigidity.
