Types of EPS Box Molds
Here are the main classifications of EPS foam box molds, clear and easy for business communication.
1. By Molding Machine Type
A. Vertical EPS mold
work with vertical EPS shape molding machines
Simple structure, low cost, suitable for small factories, small batch production.
B. Horizontal EPS mold
Match automatic horizontal vacuum molding machines.
With vacuum system, faster cooling, smoother box surface, high output for mass production.
2. By Product Usage
A. Fresh food / Seafood box mold
Insulated foam boxes for fish, shrimp, seafood transport.
B. Fruit & vegetable box mold
Agricultural packaging boxes for oranges, apples, vegetables.
C. Cold chain logistics box mold
Thick-wall high insulation boxes for long-distance cold delivery.
D. Industrial packaging box mold
Custom buffer boxes for hardware, instruments, electronic products.
How to Choose the Right EPS Box Mold
A step-by-step guide for buyers, simple and practical for factory procurement.
1. Confirm your final foam box size & usage
• Measure inner length × width × height of your target box
• Clear application: Seafood / fruit / vegetable / cold chain / industrial packaging
• Confirm wall thickness: Standard thin wall or thick wall for better insulation
2. Match your existing EPS molding machine
• Vertical machine: Choose vertical manual/semi-auto mold
• Horizontal vacuum machine: Choose horizontal automatic mold
Make sure mold installation size, steam interface and water outlet match your machine.
3. Decide cavity quantity (production capacity)
• Small output / small factory: 1 cavity (1 out 1)
• Medium-high output: 1 out 2 / 1 out 4
• Large mass production: Multi-cavity design
More cavities = higher daily output, higher mold cost.
4. Select de-molding type
• Semi-auto manual demold: Low budget, small workshop
• Full-auto ejection mold: Save labor, fast cycle, for big factories
5. Check mold internal structure
• Reasonable steam channels & exhaust holes: Ensure even foaming, no hollow or uneven surface
• Good cooling system: Shorten cycle time, improve efficiency
• Precise mold closing: No flash (extra foam edge)
Quick selection summary
1. Box size & usage
2. Machine model matching
3. Output → choose cavity number
4. Auto or manual de-molding
5. Structure quality + price + delivery time
