Process of molding and assembling three-dimensional ornaments

A method of molding and assembling a three-dimensional ornament, comprising the steps of:

• providing a mold that has a recess, an opening formed below the recess and a plurality of molding pattern slots formed below the opening;
• filling a first material in the molding pattern slots to form a plurality of protruded decoration patterns;
• charging a second material in the opening and the recess of the mold above the first material to respectively form a projection and a contact wall, and wherein the first and second materials together form an embossment;
• removing the embossment from the mold;
• providing a hollow pen tube with a sidewall opening having an area substantially equal to that of the projection, wherein the embossment is mounted on a wall of the hollow pen tube so that the projection fits in the sidewall opening of the hollow pen tube and the protruded decoration patterns protrude from the sidewall opening of the hollow pen tube;
• and
• inserting a sleeve inside the hollow pen tube to urge the contact wall of the embossment against the wall of the hollow pen tube and the projection into the sidewall opening.
