Custom EPS/EPP Lost Foam Mold – Aluminum Alloy Styrofoam Tooling for LFC Casting Patterns, OEM/ODM

This custom lost foam mold is produced from aluminum alloy and configured to mold EPS or EPP foam patterns for the lost foam casting (LFC) route. The tool incorporates steam and cooling passages, venting, and ejection features that support uniform bead fusion and clean pattern release. Cavity geometry is machined to the customer’s pattern drawing, and the mold can be arranged for single or multiple cavities. The resulting foam pattern is intended for refractory coating, sand embedding, and metal pouring, where it is replaced by molten metal. OEM and ODM customization are available for automotive, machine tool, and industrial casting programs.

 Specifications

Mould Features

• EPS and EPP Foam Compatibility – The mold can be set up for either expanded polystyrene or expanded polypropylene beads, allowing flexibility in pattern density and surface behavior for different LFC applications.

• Aluminum Alloy Mold Body – The tool body is machined from aluminum alloy, which provides rapid thermal response during steam heating and cooling, and resists moisture in foam molding service.

• Steam and Cooling Channel Layout – Internal passages are arranged to deliver steam for bead expansion and water for cooling, helping maintain consistent foam pattern density and dimensions.

• Venting and Ejection Design – Vent paths and ejector provisions are incorporated to promote complete cavity fill and allow clean removal of fragile foam patterns without damage.

• Custom and Modular Cavity Arrangement – The tool can be built with single or multiple cavities, using replaceable inserts and split-block construction to simplify maintenance and future geometry changes.

Applications

• Automotive Casting Patterns – Foam tooling for producing expendable patterns used in engine, transmission, and structural castings.

• Machine Tool Bed and Column Patterns – Molds for foam patterns applied to machine tool beds, bases, columns, and housings.

• Pump, Valve, and Compressor Patterns – Tooling for foam patterns used in fluid handling and industrial machinery castings.

• Construction and Agricultural Machinery Patterns – Molds for foam patterns applied to heavy equipment, tractor, and implement castings.

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

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.
