Custom Lost Foam Molds – Professional Aluminum Tooling for EPS & STMMA Foam Patterns, OEM/ODM Accepted

These professional custom lost foam molds are engineered to produce expendable foam patterns used in the lost foam casting route. Each tool is built from aluminum alloy and machined to the customer's pattern geometry, with steam and cooling channels arranged to support even bead fusion and stable pattern dimensions. Venting and ejection features are incorporated to assist clean release of delicate foam shapes. The molds can be supplied in single or multi-cavity layouts and are intended for automotive, industrial, and machine tool casting programs. From design review through trial molding, the tooling is developed to match downstream metal pouring requirements.

 Specifications

Mould Features

• Pattern-Specific Cavity Machining – Cavities are cut to match customer foam pattern drawings, with draft and parting details suited to lost foam casting.

• Aluminum Tool Body – Aluminum alloy construction provides rapid heat transfer, resistance to steam service, and manageable tool weight.

• Steam and Cooling Channel Layout – Internal circuits are arranged for bead expansion and controlled cooling, helping maintain pattern density and dimensional consistency.

• Vent and Ejector Provision – Vent paths and ejector positions are selected to support complete cavity fill and clean removal of fragile foam patterns.

• Flexible Cavity Configuration – Single or multiple cavities, replaceable inserts, and split-block design allow adaptation to different production needs and maintenance.

Applications

• Automotive Component Patterns – Foam patterns for engine, transmission, and structural castings.

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

• Pump, Valve, and Compressor Patterns – Foam tooling for fluid handling and industrial machinery castings.

• Heavy Equipment Casting Patterns – Patterns for agricultural, construction, and mining machinery parts.

• Development and Trial Casting Patterns – Tooling for prototype evaluation, 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.
