ABSTRACT:
A laminate is made by first forming a substantially closed mold cavity between a pair of mold halves, then injecting a plastified synthetic resin into the cavity under pressure to substantially fill the cavity and at least partially curing the resin in the cavity to form a base body. The mold halves are then separated to leave the partially cured body in one of the mold halves with a face of the body exposed and a deformable sheet is laid over the face of the body in the one mold half. A die having a face conforming at least generally to the shape of the body face is then laid down against the sheet onto the body to press the sheet into intimate contact with the body face and bond the sheet and body together.
