This Lunch Box Plastic Injection Machine is typically selected when production requirements include:
- Stable cycle performance in 24-hour operation
- Multi-cavity molds (4–8 cavities) as standard configuration
- Strict control of unit production cost
- High consistency in thin-wall injection molding
It is widely used in food packaging factories, disposable container manufacturers, and high-output injection molding production lines.
The price of the Lunch Box Plastic Injection Machine varies based on configuration level and production requirements for industrial food packaging lines.

Production Reference
Actual output depends on mold design, cooling efficiency, and cycle configuration:
|
Mold Cavity |
Cycle Time |
Output Range |
|
4-cavity |
18–25 sec |
800–1200 pcs/hour |
|
6-cavity |
15–22 sec |
1200–1800 pcs/hour |
|
8-cavity |
12–18 sec |
1600–2200+ pcs/hour |
Cycle time is affected by:
- Cooling system efficiency (main factor)
- Wall thickness of the lunch box
- Runner system design
- Injection pressure stability
- Mold steel thermal conductivity
Output is based on the PP material standard food container production conditions.
