Case Study: Upgrading Manual Stacking to a Fully Automated Robotic System
How a Middle-East aluminum recycling plant increased efficiency and eliminated safety hazards.

1. The Challenge (项目背景与挑战)：
A leading aluminum recycling plant in the Middle East was struggling with their ingot stacking process. They relied heavily on manual labor, which led to inconsistent stack shapes, frequent packing failures, and high safety risks due to the extreme heat of the ingots. Furthermore, the manual process could not keep up with their newly upgraded high-speed chain-type casting machine.

2. Our Solution (解决方案)：
We integrated a FANUC Robotic Palletizing System at the end of their casting line.

• Equipped with a heavy-duty 150kg gripper and 360-degree rotation.

• Synchronized with their double casting lines for multi-point grabbing.

• Implemented a custom PLC program to ensure perfectly aligned stacks tailored for their specific strapping machine.

• No pit foundation was required, saving significant installation time and civil engineering costs.

3. The Results (项目成果)：

• 100% Labor Reduction: The client completely eliminated manual stacking for this line, saving 3 operators per shift.

• 24/7 Continuous Operation: The robotic arm operates smoothly even in high-temperature environments, ensuring non-stop production.

• Perfect Stacking Quality: The automatic clamping mechanism ensured a neat and stable stack every time, reducing packaging material waste by 15%.

• ROI within 8 Months: The savings in labor and packaging costs allowed the client to recover their investment in less than a year.

Gantry vs. Robotic Palletizer: How to Choose the Right Stacking System for Your Aluminum Casting Line

Introduction: In the aluminum recycling and smelting industry, upgrading to an automated ingot casting line is a massive leap forward. However, many factory owners overlook the very last step of the process: stacking and palletizing. Manual stacking is not only extremely...

 Selection Guide: How to Choose the Right Palletizing System for Your Plant?
Tailored solutions for the specific needs of Southeast Asian and European aluminum manufacturers.

Choosing between a Robotic Palletizer and a Gantry Palletizer depends not only on your casting capacity but also on your factory layout and regional operational requirements.

🇸🇬 🇹🇭 🇻🇳 For Southeast Asian Markets: Focus on ROI and Space

In Southeast Asia, factories often face rising labor costs, space constraints, and the need for quick returns on investment.

• Choose the Robotic Palletizer if:

  • You don't want civil engineering works. Our robotic system requires no pit foundation, making it perfect for leased factories or quick installations.

  • You want to tackle labor shortages. The system fully replaces 2-3 manual workers per shift, solving the issue of high turnover and labor fatigue in hot environments.

  • Your factory has high humidity/temperatures. Equipped with globally recognized robots (FANUC, ABB), it operates stably under harsh tropical conditions with IP-rated protection.

• Choose the Gantry Palletizer if:

  • You have a limited initial budget. The gantry system offers excellent cost-effectiveness for single-line, high-volume production.

  • Your ingot specifications are fixed. It provides highly reliable, continuous stacking with minimal maintenance costs.

🇪🇺 🇩🇪 🇬🇧 For European Markets: Focus on Safety, CE Standards, and Automation

European clients prioritize stringent safety regulations, environmental protection, and seamless integration with existing Industry 4.0 systems.

• Choose the Robotic Palletizer if:

  • You require high flexibility. Ideal for handling varying ingot weights (5kg to 15kg) or switching between aluminum ingots and bars.

  • You need seamless multi-line integration. It can synchronize with double casting lines simultaneously, ensuring maximum throughput.

  • Strict safety compliance is a must. Our systems are designed with European safety standards in mind (light curtains, safety fences, CE-compliant components).

• Choose the Gantry Palletizer if:

  • You need ultra-low energy consumption. The simple PLC-controlled mechanical structure consumes less power during continuous 24/7 operation.

  • You want zero dust generation. The gantry design minimizes moving parts near the hot ingots, ensuring a cleaner working environment.

Quick Technical Comparison (选型速查)

• Robotic Palletizer: No pit required | Highly flexible | 360° rotation | Perfect for double lines | Higher initial cost.

• Gantry Palletizer: PLC controlled | Simple structure | Fixed stacking path | Lower maintenance | Requires larger footprint.
