1 Precision gravity die casting

2 Bögra precision gravity die casting: The economical route If it is price and precision that count, then you can rely on Bögra precision gravity die casting. Achieving the precision of GTA14 with in the accordance of DIN1687, the results can provide a reduction in the need for further processing. By using sand and/or steel moulds we are able to continuously reproduce even the most difficult shapes with intersecting contours and holes. Furthermore, depending on the alloy and application requirements, Bögra precision gravity die casting can offer still more benefits: Outstandingly precise surfaces, requiring no further processing High strength characteristics Extremely corrosion resistant structural components Consistently high conductivity even in large castings of chromium copper and high-conductivity copper Gravity die casting can be used for casting weights from 10 grams to 30 kilograms. The gravity die casting method is particularly suitable for the following materials: Aluminium bronzes Brasses and special brasses Chromium copper and high-conductivity copper

3 Before manufacture, come planning and consultation Typical applications for Bögra gravity die cast components are the electrical industry, in pumps, in toilet and bathroom fittings, in drive trains, in printing machinery and many other industries. Bögra can advise you on detailed aspects of your design and offer assistance in the selection of the most suitable design shapes for casting and the optimum material for the product. You will have access to specialists from our foundry, our product-development, our laboratory and quality assurance staff.

4 Bögra competence in bronze Intensive research and continuous development work, coupled with the know-how acquired during many decades of specialisation in this field, enables us to guarantee to our customers the suitability of Bögra precision cast components for the widest variety of applications. Bögra has developed gravity die casting to the point where any requirements for dimensional precision, density, conductivity or pressure resistance can be met. Even complex shapes with undercuts are no problem for Bögra. Our precision die casting materials A selection from our range of materials (other materials on request) High-conductivity copper Cu-C according to DIN EN High purity copper of excellent quality and very high electrical and thermal conductivity. Used in the electrical industry for all current carrying parts in distribution and switching systems, for electrode arms and holders and for contact jaws. Chromium-copper CuCr1-C according to DIN EN A hard and strong conductive copper alloy with high wear resistance. Used in the electrical industry for current carrying parts, e.g. in switch manufacture, where high wear resistance is required together with high electrical conductivity. T48 CuAI10Fe2-C according to DIN EN This alloy exhibits high corrosion resistance to saltwater and acids. It is used in the food industry and for acid resistant fittings.
