Cutting thermoform tool change times

Thermoforming machinery supplier Brown says the quick-change features it now offers on its C-series and CS-series thermoformers with T- or V-series trim presses can help processors achieve product-to-product changeover in two hours or less. Key process variables covering form, index, oven, feed, and eject variables can be stored and then downloaded into the process controllers during set-up. A note section within the recipe also allows for keeping key process notes and settings for auxiliary equipment setup.

The rails on the thermoformer incorporate v-tracks mounted on top of the rails to ease rolling of tools into or out of the form station. No additional tool carts are required. The upper and lower platens are coupled with utility quick disconnects. Motorized rails facilitate a quick repositioning of the rails for different sheet widths.

The trim press incorporates a side-loading feature that allows the trim tool assembly to be rolled in and out. This also can eliminate the need to remove parts tables, part handling equipment, and granulators during tool change. Quick-change cylinders within the moving platen permit the moving side of the tool to be quickly mounted for final alignment with the stationary tool side. The stationary side is then bolted into a rigid position. Brown Machine, Beaverton, MI; www.brown-machine.com.
