Fiber plugs for aluminum casting
Our fiber plugs are designed to precisely control the flow of molten aluminum and aluminum alloys during casting processes.
Manufactured using vacuum forming technology, these plugs offer heat resistance up to 1,300 °C and higher, depending on the fiber, durability, and dimensional accuracy.
They are widely used in foundries, aluminum casting plants, and industrial furnaces, ensuring safe and reliable production under extreme conditions.

We make the plugs from ceramic fiber and from AES fiber. Which fiber is right depends on the metal and the temperature. Send us your drawing and we will recommend the fiber.
Focus on quality:
Every plug undergoes strict quality control to meet the demands of modern foundries and aluminum producers.Frequently Asked Questions (FAQ)
What is the maximum temperature the plugs can withstand?
Our fiber plugs are heat resistant up to 1,300 °C and higher, depending on the fiber, making them ideal for continuous use in foundries and industrial furnaces.
Do you offer custom-made fiber plugs?
Yes, we provide custom-designed plugs based on customer drawings and specifications, including unique shapes, diameters, and hardness levels.
What materials are used in the plugs?
Our plugs are made from high-quality ceramic fibers, biodegradable fibers, and mineral fibers, ensuring they are asbestos-free and safe to use.
Where are these plugs typically used?
They are primarily used in aluminum casting plants, foundries, and industrial furnaces to safely control the molten metal flow.
How quickly can orders be delivered?
We offer fast delivery times for standard products. Custom-made plugs may require additional lead time, depending on complexity and quantity.
