Box Forms

New Hampton Metal Fab offers a unique "Engineered" hydraulically collapsible core system. Each corner is built with high tolerance machined parts and is assembled in a fixture to ensure a perfect corner every time. The box corner collapsing mechanism is designed to lock over center preventing the core from collapsing after the product has been poured. The core is designed to maintain its shape and won't skew. The corner is available with a haunch or square corner.
