Abstract
A process for the manufacturing of non-reinforced load carriers ( ) of thermoplastic material. Sheet-shaped work pieces ( ) and extended bar sections ( ) are manufactured by means of an extruder. The work pieces ( ) and bar sections ( ) are allowed to cool and post-shrink after the manufacturing. An upper and a lower deck member ( and respectively) are molded in a number of molds comprising mold halves. A first mold contains shaping cavities being a negative representation of the upper deck member ( ). A second mold gives shape to a lower deck member ( ). The work pieces ( ) are molded against each one cavity by means of vacuum and are pressed together while still hot whereby a hollow unit is formed. Skids ( ′) are molded in a similar way. The parts are allowed to cool and post-shrink whereupon they are joined with each other via a number of joining areas ( ).
