Gate Puzzle Coil Heaters For Hot Runner

Gate Puzzle Coil Heaters are specialized heating elements designed for hot runner gate systems in plastic injection molding. They provide localized heating at the gate (entry point of molten plastic into the mold cavity), ensuring:

• Consistent melt flow

• Prevents gate freezing (cold slug formation)

• Reduces stringing & drooling

• Improves part quality & cycle time

Commonly used in multi-cavity molds, thin-wall molding, and high-precision applications (e.g., medical devices, electronics).

• Its compact and flexible design means it can fit into tight spaces in gate areas.

• It can be used at high temperatures:It works with engineering plastics (e.g. PEEK, PC, Nylon)

• Materials that do not rust:A stainless steel case or Incoloy to make sure it lasts a long time.

• You can choose from different shapes: helical, flat or cartridge-style, to suit different gate designs.
