OVERVIEW:
Gas & Water Assist Machines
Gas assist injection molding is process by which nitrogen is injected into the mold to create a hollow channel within a part. Among the reported benefirts are lower part weights and material costs and faster cycles. Water-assisted injection molding is a newer to mold hollow or partly hollow parts. It’s basically similar to gas-assist molding as a means to core out thick sections. But water-injection technology (WIT) comes with a big advantage: direct cooling inside the part
