About FISA Corporation

FISA Corporation designs, manufactures, and supports hot runner systems and temperature control components for the plastic injection molding industry. Our website is the technical reference point for that work: it documents the PLAGATE valve gate system, the NH, AH, and NR nozzle series, and the thermocouples, cartridge heaters, and ring heaters that keep a mold at process temperature. Every product page carries the specifications, part numbers, and pricing a buyer or engineer needs before making a purchasing decision, alongside the operation and maintenance documentation required on the shop floor.

This site is built for the people who actually run molding operations — process engineers evaluating a valve gate retrofit, tooling shops specifying nozzles for a new mold, maintenance teams sourcing replacement heaters, and purchasing managers who need a clear part number and a real price. Rather than marketing abstractions, we publish the dimensions, wattages, resistances, and mounting guidance that let a technical reader make a decision quickly and correctly.

FISA has been manufacturing injection molding components since 1961 under the principle of Future Innovations Striding Ahead. The company operates from its headquarters and serves molders internationally through direct support and distribution. Our engineering and support staff maintain this site directly, publishing product updates, application notes, and industry insights through the blog so that the information here stays current with the hardware we ship.
