Abstract

The invention is basically a method of connecting two pieces of material with a molded object in between them. This method is basically done by a mold in which the material can be inserted within. In the preferred embodiment, the applicant is creating a frame in which all four corners are molded. In this embodiment the framing material forming the sides is inserted into the corner molds. The plastic then is injected or put in the molds. When the plastic hardens and the materials taken out of the molds, one has a frame in which the four corners have been molded and the framing pieces are securely attached to the four corners. In the preferred embodiment, to more securely attach the corner pieces to the molded corner, the framing material forming the sides has predrilled openings. This forms a more secure attachment between the molding corner and the material forming the sides of the frame.

Claims7

Dependent claims

A process for producing a shipping base for an item comprising:

a. using a mold which allows for at least three pieces of nonflexible material to be inserted within said mold;
and,
b. locating the mold on a platform;
and,
c. inserting the pieces of material into the mold such that the mold forms the corners of a frame such that the pieces of material inserted into the mold form the sides of the frame and are of sufficient strength that they can form and be used as the sides of a shipping base without breaking;
and,
d. moving the mold to a site for the addition of plastic to the mold;
and,
e. adding sufficient amount of plastic to the mold and said plastic flows around the ends and sides of the material such that the plastic forms the corners of the frame and the pieces of nonflexible material inserted into the mold to form sides of the frame and the plastic is of sufficient strength that when the frame is used as a shipping base it will not break and the bond between the plastic and the material is of sufficient strength that when the frame is used as a shipping base the plastic and the nonflexible material will not pull apart;
and,
f. moving the mold past the site where plastic is added;
and
g. waiting for the plastic to begin to harden;
and,
h. removing the frame from the mold.
