Wire & cable production technical service, extrusion stranding, drawing, training. Bernard dougoud engineering provide technical service to the wire and cable industry, machines builders, cable manufacturer, second hand machines seller. Pgrade and retrofit of cable making machine will increase the quality of the products, reduce the scrap druring the start and the color change sequences, because of the higher stability of the line the product can be kept at the lowest limit of t^dimensional tolerance what can save up to 15 % of the insulating material. In the case of raio frequency cable the upgrade to the physical foaming process with injection of nitrogen will result in a lighter insulation with better electrical properties, less attenuation and return losses, the economy on the raw material can reach 60 % compared to the same product with solid insulation. Multilayer cable: Nowaday, it is possible to produce using a certain amount of reprocessed raw material, I that case the reprocessed compound will be extruded between two layers of virgin compound what will insure a good surface finish and the perfect adhesion of the insulation of the coating on the condutor. Jacketing + filling: Usually thes operation are performed in 2 passes with an important manutention of reels plus the requirement of a large floor surface t store the drums of product between the two operations, wit the filling jacketing in one path with one or two extruders, it is possible to reduce the inner layer diamter to a minimum, this layer can be made of reprocessed compound, the outer layer applied with a high precision cross head with a micro adjustment guarantee the electrical properties of the cable, the overall diameter will be reduced to a minimum saving a large a ount of expensive raw material. Upgrade to Fluoropolymer: Just changing the extruders barrel the line will be capable of extruding high performance compound, Highest value cable can be extruded with higher profit and less competition. Bernard Dougoud Engineering guarantees the successful of the Ugrade and/or retrofit because not only the modifications are carried out by our specialists but because we also perform the production tests and give the training to the customer. |
