Hot runner technology has a crucial impact on the cost-effectiveness and part quality in
injection molding. As a pioneer in hot runner technology, we focus on the development
and manufacture of Cylindrical Valve Gate Systems – recognized as the best hot runner
solution for achieving impeccable surface quality, part-to-part consistency, and process
reliability. All valve gate systems are custom tailored and designed to meet the specific
needs of our customers
