ABSTRACT:
A hinged plastic housing and a process for making same wherein a hinge formed from a deformable lamina is integrated with first and second enclosing members during injection of the plastic material. The deformable lamina is placed between the first mold section and the second mold section of an injection mold unit before the first mold section and the second mold section are clamped together to form injection mold cavities for the first and second enclosing members. The deformable lamina at least partially extends into the mold cavity for the first enclosing member and the mold cavity for the second enclosing member as well as therebetween. The first mold section and the second mold section are then clamped together and a plastic material is injected into the mold cavities and in bonding securement of the deformable lamina. The resultant housing is then removed from the mold unit with the deformable lamina hinge integrated with the first and second enclosing members. The deformable lamina may extend over the entire exterior or interior surfaces of the first and second enclosing members to form a combined hinge and exterior covering or interior lining respectively.
