A method for manufacturing a skate shell has acts of providing an expandable sheet (10), providing a mold assembly (20), forming the sheet (10) into a three dimensional shape, mounting the shaped sheet (18) around an inner mold (24), closing the mold assembly (20), forcing molten plastic material into the mold assembly (20) and opening the mold assembly (20). The inner mold (24) has a mold block (242). The sheet (18) has a peripheral rim (12) squeezed by the mold assembly (20) when the mold assembly (20) is closed and positioned onto the mold block (242) with a positioning assembly. The plastic material is injected into the mold assembly (20) and combined with the shaped sheet (18) to make the sheet (18) smoothly bonded to one surface of the skate shell in a three dimensional arrangement.
