Polyshot - Injection Molding Solutions with Hot Runner Systems

For over two decades, Polyshot Corporation has provided hot runner systems to injection molding customers worldwide. Our hot runner technology ensures user-friendly, reliable systems for processing molten plastic

Hot Runner Systems and Components

Hot runner systems consist of a core molding plate, hot runner components, and a hot runner temperature controller, which maintains optimal temperature and mechanical settings for the hot runner mold. The injection molding machine nozzle connects to the hot runner system, ensuring seamless integration.

Plate Fusion Technology: Hot Runner Technology

Plate Fusion Technology, our core technology for manifold construction, fuses 2 or more manifold layers, creating perfectly round, smooth flow paths. This hot runner technology eliminates abrupt 90-degree turns and turn plugs in manifold systems. Polyshot is the only company building 100% of its hot runners this way.

What Is a Hot Runner?

A hot runner is a system in injection molding that replaces traditional cold runners by internally heating and delivering molten plastic directly into mold cavities – reducing cycle time, waste, and energy consumption for a more sustainable manufacturing process.
