A molding apparatus and method of use thereof. The molding apparatus has a stationary mold base, and at least one moveable mold core rotatable into and out of a facing relationship with the stationary mold base. When the moveable mold core is in its closed position, it cooperates with the stationary mold base to define a mold cavity. The mold base may be shaped so as to aid in forming a part, or to hold a sheet of material onto which molding material is to be deposited so as to encapsulate the part on one or more edges or surface regions. Structure may also be encapsulated onto the surface of the material during the molding operation.

A window frame assembly is provided with a sliding glass mechanism and seal system for vehicular backlites. The assembly includes a pair of fixed side windows secured in a frame in spaced-apart relationship, and one or more sliding windows positioned in channel brackets to close and open the aperture between the fixed window panes. A single gasket formed by a reaction injection molding process is formed around the periphery of the window assembly for mounting the window assembly in the opening of a body panel of a pickup truck. The gasket is integrally formed about the aperture during the reaction injection molding process and includes a flexible lip to engage the sliding window. The sliding window slides in the channels of the channel brackets and is positioned to engage the lip of the gasket to seal the aperture. The required sliding force to open and close the sliding window may be reduced by spring loading the sliding window in the channel. Channel guides with a spring mechanism are placed on the top and bottom edges of the sliding glass. A cam formed in the channel bracket is used to compress the springs and force the sliding glass window against the lip of the gasket to sealingly close the aperture. When the sliding window is in the range of open positions, the spring mechanism clears the cam and forces the sliding window away from the lip of the gasket to facilitate sliding of the glass.

The sliding window slides in the channels of the channel brackets and is positioned to engage the sealing lip of the gasket to seal the aperture. A channel liner continuously engages the horizontal edges of the sliding window to maintain the sliding window in tension in the channels. A leading edge gasket is formed on the vertical edge of the sliding window. The leading edge gasket is provided with a beveled outer edge to facilitate the movement of the sliding window past the sealing lip of the gasket.
