Revolutionizing Heavy Industry: Ductile Iron Castings for Railways, Trucks, and Solar Energy

🏭 Introduction: Why Ductile Iron Matters
For over 30 years, ALD Precision Manufacturing Co., Ltd. has specialized in the production of ductile iron castings that serve as the backbone of critical infrastructure worldwide. From railway braking systems to slewing housings in solar trackers, our high-strength cast components are trusted across the globe.
In today’s world of electrified vehicles and renewable energy, the material behind the machine matters more than ever.

🚆 Railways: High-End Brake Discs That Deliver
Train brake discs require thermal resistance, dimensional stability, and durability under heavy loads. Our ductile iron brake discs are manufactured to tight tolerances and heat-treated using our in-house ADI (Austempered Ductile Iron) line.
• Increased brake disc life by 30% compared to traditional grey iron
• Low warping rate during extended operation
• Used by national rail systems and export to Europe

🚚 Automotive Industry: Flywheel Housings & Pulleys
Ductile iron's shock resistance and load-bearing capacity make it ideal for automotive flywheel housings and belt pulleys.
• Common applications: commercial trucks, electric vehicles, tractors
• We serve OEM suppliers in Germany, the US, and South Korea
• Optional machining, painting, and sub-assembly included

☀️ Solar Energy: Slewing Drive Castings
As the solar energy market grows, our slewing bearing housings are in high demand for PV tracker systems.
• Precision-cast ductile iron parts, ready for machining
• Heat-treated for outdoor durability
• Lightweight design for rotational balance
