    摘要： A method for filling polymer materials into a hot-mold for manufacturing a multizone polymer blank. At least one partitioning section is positioned in the blank mold cavity of a mold to partition the blank mold cavity into at least two independent compartments not communicating with each other. Different polymer materials are respectively filled into the corresponding independent compartments. After the filling of the materials is completed, the partitioning section is removed or the partitioning section is combined with the filled materials to form a multizone blank.

    摘要： A method of making a cover comprising a pair of welded thermoplastic polymer sheets having therebetween a stiffener. A stiffener is provided such that the stiffener has a leading edge, a trailing edge, and two side edges. A pair of thermoplastic polymer sheets are positioned on opposite sides of the stiffener. The thermoplastic polymer sheets each have two side edges substantially parallel to the side edges of the stiffener. The thermoplastic polymer sheets are ultrasonically welded around the periphery of the stiffener. The polymer sheets are cut to form a leading edge and trailing edge which are substantially parallel to the leading edge and trailing edge of the stiffener. The thermoplastic polymer is typically selected from the group consisting of polypropylene and a copolymer of ethylene or butene and propylene, the weight percent of ethylene or butene being between about 1 wt. % to about 10 wt. %, and containing a sufficient amount of a nucleating agent to raise the recrystalization temperature to between about 100° C. to about 140° C.
