Coupons machining, metal, plastic and composite materials<\/h3>\n

For many years now, ORATECH has specialized in cutting and machining metal, composite and plastic coupons.<\/p>\n

Due to the strong market demand for composite coupons, particularly in aeronautics, we at ORATECH have organized ourselves to fully meet the expectations of customers (laboratories and contractors) in terms of volume management, quality and responsiveness.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/3″]

Machining composites coupons<\/h3>\n
    \n
  • Taking composite test pieces from a flat sheet or complex part (angle, stringers, beams, etc.)<\/li>\n
  • Coupons machining and cutting according to standards, precision drilling<\/li>\n
  • Dimensional \/ three dimensional control and verification<\/li>\n
  • Non-destructive testing (ultrasound) after test piece machining<\/li>\n<\/ul>\n

    Complementary services such as sheet manufacturing, stub bonding as well as mechanical, physico-chemical, and micro cutting tests are provided by our historical partners. The supply chain is fully integrated and allows for very short lead times with optimum quality.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_single_image image=”12995″ img_size=”585×520″][\/vc_column_inner][\/vc_row_inner][vc_empty_space][vc_row_inner][vc_column_inner width=”1\/2″][vc_column_text]<\/p>\n

        MACHINING OF COMPOSITE COUPONS FOR HYDROGEN TANKS<\/h3>\n

        [\/vc_column_text][vc_row_inner content_placement=”middle” gap=”35″][vc_column_inner width=”1\/2″][vc_column_text]The machining of composite coupons for hydrogen tanks enables to perform mechanical and\/or physico-chemical characterization testings. It can be used for prototyping, expertise or recurring sampling in manufacturing.<\/p>\n

        It allows to check the presence of material defect (for example: air bubble, lack of fibre and\/or resin\u2026) and to validate mechanical characteristics of \u00a0the tank cylinders.<\/p>\n

        We start by cutting out \u00a0cylinder sections (in washers) of the hydrogen tank. Then, we sample coupons in the longitudinal and radial direction, with or whitout thickness surfacing, in order to get flat coupons.<\/p>\n

        We have the possibility to stick resin beads in order to recover the curvature and performed testing with no need to impact the material.<\/p>\n

        Finally, we cut out the part containing the fitting (multi-materials) using water jet cutting. This one enables us\u00a0 to check the correct assembly of the metallic fitting with the composite cylinder of the hydrogen tank.[\/vc_column_text][\/vc_column_inner][vc_column_inner width=”1\/2″][vc_images_carousel images=”16218,16214,16212,16216″ img_size=”585×520″ onclick=”link_no” speed=”3000″ autoplay=”yes” hide_pagination_control=”yes” hide_prev_next_buttons=”yes” wrap=”yes”][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”64px”][vc_column_text]<\/p>\n
