Case Study: Hot Drop TipsThis was a polycarbonate part with four low-vestige hot drop tips, and the splay was appearing near the gates. The part needed to be filled fast to fill and pack out the part, but at these high velocities splay became a problem.Inspection of the gate and spreader tip showed that the gate orifice was 0.050 in and the spreader tip was 0.025 in, which resulted in a gate area of 0.00147 in 2. The gate orifices were opened up to a diameter of 0.0625 in, which resulted in a gate area of 0.00258 in 2 (a 75% increase in area). By opening this restriction at the hot drop tips the splay problem was resolved.
