Designed with independent wirings/sides

Stack Molds
Stack Molds are designed with two electrical boxes that control the heaters on each side – the moving half and the stationary half. The sprue bar is accessible and removable from the face which makes transporting, maneuvering, and maintaining the mold easier. Production can be doubled by distributing the melt into two molds thereby reducing the price per part cost. Flat parts are typically better suited for stack molds than are deep core parts because of the machine opening stroke and the increased mold height of a stack mold. Nozzle sizes and gate styles are available to produce a wide variety of part sizes.
