Multi-Cavity Runner Balance
With high cavitation (24, 32, 48 or more), runner balance becomes critical. Naturally balanced runner layouts or rheological balancing ensure consistent filling and part weight across all cavities.
Plastic Spoon Injection Mold
High-cavitation injection mold for disposable and reusable plastic spoons, supporting food-contact product production with efficient multi-cavity design.
Overview
Plastic spoons are high-volume consumable products where per-part cost and production efficiency are paramount. Multi-cavity molds with balanced runner systems, fast cycling and consistent quality across all cavities are the standard approach.
Shengqi reviews the spoon design including overall shape, bowl depth, handle thickness, edge profile, stacking features and material certification before mold design.
For food-contact products, material traceability, mold cleanliness and production documentation are important considerations beyond the mold itself.
Engineering Focus Areas
Thin-Wall Filling Control
Spoon bowls and handles are thin sections. Fast filling, proper venting and controlled packing prevent short shots, flash and warpage.
Surface Finish and Gate Vestige
Food-contact surfaces must be smooth and clean. Gate position, vestige height and mold polishing level affect product feel and hygiene.
High-Volume Production Efficiency
Fast cycling, automated part removal, minimal downtime for cleaning and simple maintenance access are designed into the mold for sustained high-volume production.
Quote Requirements
- Spoon design drawing with dimensions and weight target
- Material specification and food-contact certification requirements
- Target cavity quantity and annual production volume
- Stacking, wrapping or packaging requirements
