Applications of Rjcmold’s Stack Molds
Stack molds are two single-face molds that are mounted back to back. One half of the core is mounted to the injection-side machine platen while the other half is mounted to the clamp-side machine platen. Cavity plates are fastened to the hot runner system that is located at the center section of the mold. To prevent mold collision, the center section must be equidistant between both core halves at all times. Rjcmold’s stack molds boost productivity, often doubling or quadrupling output. This means less utility and maintenance costs.
Until recently, stack molds were used for fairly small, shallow-draw packaging and other disposable items. Today, innovation has taken hold and a variety of new concepts are broadening the capabilities of stack molds to include larger, multi-material products.
Soft-touch applications such as toothbrush handles, barrier packaging, caps and closures with molded-in liners, multi-color cell phone housings, and combination-material medical parts are in high demand. As knowledge of the benefits of stack molds increases, mold makers and customers alike look to them when applications justify their use.
