12x10 mm tunnel gate - banana gate 3D model

This is a real-dimension tunnel gate system (12×10 -1,2 mm) designed for use in plastic injection molding.Tunnel gates are critical components that guide molten plastic into the mold cavity in a controlled and efficient manner. Their tapered geometry helps reduce visible gate marks on the finished part, supports automatic part ejection, and ensures consistent flow and pressure during molding.

These gate designs are widely used in industrial production for their reliability, clean finish, and repeatability. Ideal for professionals who seek practical, production-ready components for mold making and high-volume plastic part manufacturing.
