In the precision-driven world of aluminum casting, maintaining metal purity and controlling thermal distribution are the keys to high-quality output. Explorer is proud to present our industry-leading TF Combo Bag (Thermally Formed)—a revolutionary solution designed to optimize the filtration and distribution of molten aluminum for global foundries.
Why the Explorer TF Combo Bag Outperforms Traditional Alternatives
Unlike standard sewn bags, the Explorer TF Combo Bag is manufactured using an advanced thermal forming process. This eliminates loose threads—a major cause of inclusions—and ensures the bag maintains its rigid, three-dimensional geometry even under the intense pressure and heat of continuous casting.
Superior Advantages of the TF Combo Bag:
- Precision Metal Distribution: The TF Combo Bag is engineered to direct molten aluminum outward and evenly toward the mold walls, ensuring high-temperature metal is distributed where it’s needed most to optimize casting microstructure.
- Reduced Turbulence: By facilitating a smooth lateral flow beneath the metal surface, the TF Combo Bag significantly reduces turbulence and prevents the formation of oxide skins.
- Advanced Thermal Control: Our bags help manage thermal gradients, effectively reducing common defects like butt curl and scalping in VDC slab casting.
- Eco-Friendly Engineering: Utilizing next-generation environmental protection materials, the TF Combo Bag produces no smoke, fumes, or flames during operation, ensuring a cleaner and safer foundry environment.
Targeted TF Combo Bag Material Solutions for Every Temperature
Explorer offers two specialized material grades for the TF Combo Bag to meet the diverse demands of the metallurgical industry:
1. Fiberglass TF Combo Bag (700°C – 900°C)
Developed specifically for standard aluminum ingot and rolling slab casting, this version offers exceptional structural integrity for up to 150 – 600 minutes in molten metal, making it the ideal choice for high-volume VDC slab casting.
2. Carbon Fiber TF Combo Bag (1000°C – 3000°C)
For extreme environments and ultra-high-purity applications, our carbon fiber TF Combo Bag provides unrivaled heat resistance and chemical stability, preventing secondary contamination even at temperatures reaching 3000°C.

Technical Specifications and Customization of the TF Combo Bag
Explorer provides a comprehensive range of dimensions to ensure the TF Combo Bag fits perfectly into your existing mounting systems. We offer standard lengths of 330mm, 406mm, and 457mm (13, 16, or 18 inches), paired with heights ranging from 89mm to 152mm (3.5 to 6 inches).
To accommodate different distribution pan widths, our bags are available in 102mm, 127mm, and 152mm (4, 5, or 6 inches) options, featuring end patches between 25mm and 140mm (1 to 5.5 inches). Beyond these standard sizes, Explorer specializes in fully customized TF Combo Bag designs. We can adjust the fabric style, drainage hole configuration, and structural reinforcement to meet the specific requirements of your technical drawings.
Operational Guide: How to Use the TF Combo Bag?
- Selection: Match the TF Combo Bag dimensions to your distribution pan or spout to ensure a tight fit and prevent metal bypass.
- Installation: Simply slide the bag into the mounting hardware. The rigid, pre-formed structure of the Explorer bag allows for effortless “drop-in” installation.
- Orientation: Ensure the bag is aligned to facilitate lateral flow toward the mold walls for optimal thermal distribution.
- Removal: After the casting cycle, the bag can be cleanly removed once the metal has solidified, leaving minimal residue on your equipment.
Frequently Asked Questions about the TF Combo Bag
Q: Why is a “Thermally Formed” TF Combo Bag better than a sewn version?
A: Thermal forming uses a hot die to shape the bag, creating a rigid structure with zero loose threads. This ensures consistent flow patterns and significantly cleaner aluminum.
Q: Can the TF Combo Bag handle long casting durations?
A: Yes. Our fiberglass models remain rigid for over 90 minutes, while our carbon fiber models are designed for even more demanding, high-heat durations.
Q: Is the TF Combo Bag safe for operators?
A: Absolutely. Our bags use a non-toxic coating that does not release VOCs or harmful fumes upon contact with molten aluminum, protecting both your staff and the environment.
