In the precision chain of automotive manufacturing, the recycling of defective aluminum castings has always been a troublesome aspect. Their large volume and complex structure lead to a “triple-high” challenge in recycling: high difficulty, high cost, and high value, causing traditional processing methods to be inefficient and leaving valuable renewable resources in an awkward position—”unappealing to use yet wasteful to discard.”
Faced with this common industry problem, Wali, leveraging its profound technical expertise and innovative spirit, has delivered a satisfactory answer—our industry-first “One-Stop Shredding Solution for Aluminum Castings,” which has completely rewritten the processing model for recycling defective aluminum castings.
In the past, processing large defective aluminum castings often required multiple pieces of equipment and numerous steps, resulting in cumbersome processes and significant space requirements. Wali’s innovation lies in this: only one customized large dual-shaft shredder is needed to replace the traditional lengthy production line, achieving a one-step process from whole castings to ideal shredded material. This dramatically reduces the required footprint, enables cost-effective recycling, and helps customers maximize their benefits.
This is not just an upgrade in equipment; it is a revolution in processing philosophy. For the first time, Wali has deeply integrated “efficient shredding, safety protection, automatic feeding, and cost control” within a single system, offering customers unprecedented simplicity and efficiency.


Its core advantages are reflected in:
Je. Custom Alloy Blades
Specifically developed for the characteristics of cast aluminum materials, ensuring strong shredding power and lasting durability even within complex structures.
II. Large Dual-Shaft Shredder with 3-4 t/h Processing Capacity
Features low speed and high torque, providing high-intensity shredding power capable of handling large-volume castings while being extremely energy-efficient.
III. Panoramic Visual Safety Guard Mesh
Combines mesh guard panels with operational monitoring, ensuring absolute safety while making the feeding process clear and easy to manage and maintain.
IV. Fully Automatic Feeding System
An integrated hoist enables the automatic feeding of defective parts, fundamentally eliminating the risks associated with manual operation and enhancing overall efficiency.
√ Through this industry-first technical approach, we have opened a new value-recycling channel for industrial defective parts. When shredding is no longer the end point but the starting point for regeneration, every piece of cast aluminum will carry efficiency and benefit back into the manufacturing cycle.





Behind this “industry-first” lies Wali’s consistent commitment to its customers. We do not just provide a machine; we offer a one-stop service encompassing needs analysis, solution customization, equipment commissioning, and after-sales support. We delve into our customers’ sites, share their concerns and solve their difficulties, ultimately helping them maximize both resource recycling efficiency and economic benefits.
