In the world of lost foam casting, the quality of the pre-foamed beads determines the final success of the casting process. The AUTO SPECIAL LOST FOAM PRE-EXPANDER is engineered specifically to meet the demanding needs of high-performance foam production. With cutting-edge automation, precise temperature control, and intelligent material handling, this machine is the ideal choice for factories pursuing efficiency, consistency, and energy savings.

Key Features:

Tailored for Lost Foam

Unlike general-purpose pre-expanders, this model is purpose-built for the lost foam process. It ensures uniform cell structure, ideal bead density, and controlled expansion—critical for creating high-fidelity foam patterns.

Full Automation System

From feeding to discharge, every stage is automated. The PLC system offers intuitive operation, programmable cycles, and real-time monitoring, minimizing human error and maximizing productivity.

Accurate Density Control

The machine supports fine-tuned steam and temperature regulation, making it easy to achieve precise expansion ratios. Whether you’re working with EPS or other foam materials, density consistency is guaranteed.

Energy-Efficient Operation

Designed with insulation optimization and smart steam utilization, the AUTO SPECIAL pre-expander reduces energy consumption while maintaining top output performance.

Easy Integration & Maintenance

Modular structure and compact design make installation simple. Key components are easy to access, reducing downtime and simplifying routine maintenance.
