openings however by placing the openings in the framing material one can increase the different types of plastic and the different types of framing materials used the molding can be done by injection molding this would allow the molded corners and the shipping base to be quickly and cheaply manufactured however several other types of molding could be used the corners could also be cast to make the shipping base the molds 32 are basically placed on a movable conveyor belt as the mold 32 moves along the conveyor belt the framing pieces 16 20 22 and 24 of the shipping base are inserted into the molds 32 then the mold 32 will roll under the plastic injection machine which will make contact with the mold 32 and inject the plastic into the mold 32 the mold 32 then rolls out of the plastic injection machine and the plastic cools and the shipping base is removed from the mold 32 and the mold 23 is sent back on the conveyor to make another shipping base also by using molded corners you can mold these corners into any shape which is necessary thus the shipping base can accommodate wheels on the appliances or feet this is shown in fig1 fig1 shows an opening 38 placed in two of the corners which could accommodate wheels or other items protruding from the bottom of the appliance the other two corners are also cut away to accommodate wheels or feet or other items protruding from the bottom of the appliance cut aways 42 are shown in the other two corners one also sees smaller openings 44 in two of the corners these smaller openings 44 were designed for locating devices.
