Big injection molding machines leave a big impression

Big parts — including car parts, water reservoirs, battery and data-storage systems and containers — require big machines to make them. In September, Plastics Machinery & Manufacturing covered the special demands and challenges of running these behemoths with clamping forces of 1,000 tons and up.

While it's hard to capture the size of these IMMs in photos, this gallery shows some of what goes into big-part molding.
