1. The gate with the small core
2. The mold gate processing is simple
3. Color change is effective. As these gate styles have very small insulation layers for improved color changing
4. For the low melting point material, this style is suitable for multi-production by reducing the impact and abration to the mold gate material
5. Compared with D1 style nozzle. It is more suitable for amorphous due to the gate being little influenced by the mold cooling.
