Custom EPS Styrofoam Mould for Fish Box & Packaging – CNC Machined Aluminum Foam Mold for Lost Foam Casting Patterns, 0.2 mm Tolerance

This custom EPS styrofoam mould is CNC machined from aluminum alloy to a 0.2 mm tolerance and can be configured for fish box and packaging foam production, as well as for lost foam casting pattern tooling. The mold uses an aluminum body with steam and cooling channels to support uniform bead fusion and clean foam release. When used for lost foam casting, the molded EPS pattern is later coated with refractory material, embedded in sand, and replaced by molten metal during pouring. The tool can be supplied in single or multi-cavity layouts and adapted to customer drawings for both packaging foam and casting pattern applications.

Specifications

Mould Features

1. CNC-Machined Cavity with 0.2 mm Tolerance
   The cavity is machined to the specified tolerance, helping maintain consistent foam geometry for fish boxes, packaging inserts, and lost foam casting patterns.

2. Aluminum Alloy Tool Body
   The mold body is made from aluminum alloy, which provides rapid thermal response, resistance to steam exposure, and manageable weight for handling and setup.

3. Steam and Cooling Channel Integration
   Internal channels are arranged to deliver steam for bead expansion and water for cooling, supporting stable foam density and controlled cycle performance.

4. Venting and Ejection Provisions
   Vent paths and ejector locations are incorporated to promote complete cavity fill and allow clean removal of foam parts without damage.

5. Dual-Purpose Mold Configuration
   The same tooling platform can be adapted for fish box and packaging foam production or for lost foam casting pattern molding, depending on customer requirements.

Applications

• Fish Box Foam Production
  Molds for EPS fish boxes used in seafood storage, transport, and cold chain logistics.

Our Advantages
1. We are the biggest lost foam mould manufacturer in China, we focus on high challenge lost foam mould and we have large gantry machining centers,30 sets imported high speed machining center,more than 40 sets general machine tool equipment;
2. We have 36 senior mould designers, to ensure reasonable / safety / high efficiency mould design and ensure the fast mould delivery and rational mould structure, make the process more safer and the production efficiency more higher;
3. We using numerical control machine tool to manufacture the mould cavities, to ensure a even thickness ;
4. We using ZL104 Aluminium to casting the mould, to manufacture a high strength mould;
5. For the big mould, we using Ø22*1 copper tube as cooling pipe, with water spray system, to get a nice cooling effect;
6. We Have (TEF10N) coating on the mould surface, it can reduce the friction, anti water/static electricity/acid-base/high-temperature, with this we can ensure the pattern has smooth surface without distrotion, and easy to demould;
7. All the screws we using stainless steel screw, easy to disassemble during maintenance;
8. For the big mould chest, we using 18-20mm thick wrought aluminium plate, to offer high strenght cavity ;
9. For the complex mould which is difficult to demould, we can manufacture the automaitc mould with take out device ;
10. We produce the pattern sample to customer after finish the mould, when the pattern was qualified, then we do exceptance job for the mould ;
11. We have the Hexagon coordinate measuring instrument imported from the Switzerland to have a test make sure our mould qualified.
