STP Equipment’s new High Volume Shuttle (HVS) machine combines an in-line shuttle with a rocking oven design in a single large-part roto-molding apparatus. The machine comes with a raised oven and uses up to 50 percent less floor space than traditional machines. Its modular structure permits easy assembly/disassembly, accommodating growth and the frequent need to reconfigure plant layout.

Productivity improvement is incorporated into the machine by a design feature that joins oscillating oven technology with a linear platform. As the mold travels along the platform to a convection oven equipped with three to five independent temperature zones, the oven collects the mold, rises, oscillates, and then lowers to repeat the process for a fresh part. Molded parts are removed directly at the cooling station.

The HVS machine is the result of several years of research, development and testing at STP Equipment’s new, 15,000 sq. ft. research facility in Bromptonville, Quebec.
