Abstract (en)
[origin: WO9626061A1] A large surface shaped structure having a smooth surface is formed by compression molding a charge (26) of reinforced molding material containing a thermoplastic material by placing a heated mold charge (26) in a mold (12, 14) which has its peripheral surfaces spaced apart to provide a shear gap (34). The width of the shear gap (34) is adjusted to accept a quantity of molding material sufficient to dissipate residual energy in the flow front of the charge to prevent rebound of the flow front as the structure solidifies.
