INJECTION MOLDING PROCESS FOR FORMING A RETROREFLECTOR |
摘要 |
<p>An injection process for forming a retroreflector on a matrix mold having a plurality of prisms that each define a cavity. The process includes the steps of a) injecting a first layer of plastic on the matrix mold for partially filling up each prism up to a predetermined uniform thickness so as to define a recessed portion corresponding with each cavity of the prisms; and b) injecting a second layer of plastic onto of the first layer, the second layer filling up the recessed portion defined in each cavity of the prisms so that second layer defines a flat portion on an exterior side of the second layer.</p> |
