Cooling is critical for multi‑cavity cutlery moulds to achieve short cycle times. The cooling channels in multi‑cavity cutlery moulds follow the contour of each fork tine. Baffles and bubblers are used inside multi‑cavity cutlery moulds to reach deep cores.

A conformal cooling insert for multi‑cavity cutlery moulds can reduce cycle time by 30%. These inserts are 3D‑printed from maraging steel for multi‑cavity cutlery moulds. The water lines in multi‑cavity cutlery moulds should be arranged in parallel circuits.

Each cavity of multi‑cavity cutlery moulds must have a water flow rate of at least 2 L/min. An infrared camera checks the surface temperature of multi‑cavity cutlery moulds during trial runs. Uneven cooling in multi‑cavity cutlery moulds causes warped spoons.

The sprue cooler of multi‑cavity cutlery moulds removes heat from the hot runner manifold. For multi‑cavity cutlery moulds, the mold temperature should be uniform within ±2°C. A chiller unit dedicated to multi‑cavity cutlery moulds improves consistency.

The cooling time often accounts for 60% of the total cycle in multi‑cavity cutlery moulds. By optimizing water connections, multi‑cavity cutlery moulds can run on a lower tonnage press. Some multi‑cavity cutlery moulds use pulse cooling to reduce stress.

After ejection, parts from multi‑cavity cutlery moulds drop into a water bath for post‑cooling. Proper cooling design makes multi‑cavity cutlery moulds profitable for mass production. Without it, the investment in multi‑cavity cutlery moulds would not pay off.
