As a core equipment in the modern foundry industry, fully automated sand mold casting machines exhibit the following trends and characteristics in their application and development:
Current Technological Applications
Innovations in 3D Printing Technology
Sand mold printers using binder jetting (BJ/3DP) technology have enabled mold-free production, supporting the manufacturing of extra-large sand molds up to 4 meters with a printing precision of 10 microns. This is suitable for small-batch production of complex castings in aerospace, automotive, and other industries. For example, Longyuan Forming’s AFS-J series equipment has passed 1,000-hour stability tests, significantly shortening new product development cycles.
Enhanced Intelligent Capabilities
Dazhan Machinery’s fully automated horizontal molding machines integrate servo drives, visual positioning, and IoT technology, achieving a clamping accuracy of ±0.15mm and a production efficiency of 300 molds/hour while meeting environmental standards with dust concentrations below 4mg/m³.
Equipment from companies like Delin Intelligent features PLC control systems and rapid mold-changing capabilities (within 10 minutes), supporting multi-process formula storage to meet the demands of complex castings such as long-head pumps and high-flange components.
Upgrades in Traditional Processes
The adoption rate of automated molding production lines (e.g., DISA230, FMEFA-SD6) has increased, with domestically produced equipment gradually replacing imports. However, technological gaps remain in the field of ultra-large castings (>5 tons).
Industry Development Trends
Green and Low-Carbon Transformation
The proportion of electric furnace melting is expected to rise from 40% in 2023 to 55% in 2025. The next-generation “carbon-neutral molding units” reduce carbon emissions per ton of castings by 50% through waste heat recovery and other technologies.
Closed sand-shooting systems and sand recycling devices minimize sand waste, with dust emissions complying with EU EN standards.
Market Structure Changes
China’s cast iron machine market is projected to reach ¥105 billion by 2025, with high-end equipment accounting for 35%. The Yangtze River Delta and Pearl River Delta clusters dominate 70% of production capacity.
Domestic equipment prices are only 60% of imported brands, and companies like Dazhan Machinery already hold a 28% domestic market share, accelerating import substitution.
Intelligent and Customized Solutions
5G + digital twin technology is being applied to new-generation machines, achieving an equipment utilization rate of 92% and mold lifespans of 500,000 cycles.
Customized dual-station solutions for ultra-large castings, such as wind turbine flanges, are becoming a key R&D focus.
Case Studies
Automotive Sector: A Zhejiang-based company reduced labor requirements by 75% and lowered casting porosity defects from 5% to 0.3% after adopting fully automated molding machines.
Precision Machinery: 3DP sand printing technology enables aluminum castings to match the precision of investment casting while reducing overall costs by 30%.
Future Outlook: With the implementation of the Foundry Industry Carbon Peak Action Plan, fully automated sand mold casting machines will continue evolving toward higher precision, lower energy consumption, and greater flexibility.
