Custom Lost Foam Mold EPS/EPP Foam Tooling for Casting Patterns & Foam Boxes, Aluminum Mould

This custom lost foam mold is manufactured in China from aluminum alloy and designed for producing EPS or EPP foam patterns used in the lost foam casting process. The same aluminum mold platform can also be configured for foam box production where required. Cavity geometry, steam and cooling channels, venting, and ejection provisions are developed to match the customer’s pattern or box design. The mold is suitable for OEM and ODM projects, with machining, assembly, and trial molding carried out in-house. The resulting foam patterns are intended for subsequent refractory coating, sand embedding, and metal pouring, where the foam is replaced by molten metal.

Specifications

Mould Features

• Dual Foam Material Compatibility – The mold can be configured for EPS or EPP foam beads, allowing flexibility in pattern density and surface behavior for different casting and packaging needs.

• Aluminum Mold Construction – The tool body is machined from aluminum alloy, which supports rapid heat transfer during steam heating and cooling, and resists moisture in foam molding service.

• Pattern and Box Cavity Versatility – Cavity design can be adapted for lost foam casting patterns or for foam box shapes, depending on customer requirements.

• Integrated Steam and Cooling Layout – Internal channels are arranged to promote uniform bead fusion and controlled cooling, helping maintain consistent foam geometry.

• Venting and Ejection Provisions – Vent paths and ejector positions are incorporated to support complete cavity fill and clean release of foam parts.

Applications

• Lost Foam Casting Patterns – Production of expendable foam patterns for automotive, machine tool, and industrial metal castings.

• Machine Tool Component Patterns – Foam patterns for beds, columns, and housings used in machine tool manufacturing.

• Automotive Casting Patterns – Foam tooling for engine, transmission, and structural castings.

• Industrial Foam Boxes – Aluminum molds for EPS or EPP foam boxes used in packaging and logistics.

• Prototype and Trial Casting Patterns – Tooling for development projects, process validation, and small-batch production.

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.
