Boron Nitride in Foundry
Boron Nitride coatings HeBoCoat® and powdered Boron Nitride additives HeBoFill® serve as effective lubricants and release agents for metal forming processes, such as casting, extrusion, rolling, and pressing, among others.
When used as high-temperature lubricants, the properties of Boron Nitride ensure that HeBoCoat® and HeBoFill® products help prevent carburisation, overloads that can lead to equipment failures, as well as contamination and surface build-up. Furthermore, HeBoCoat® and HeBoFill® are non-toxic and environmentally friendly.
In contrast to soot and graphite, powdered Boron Nitride is electrically insulating and can be electrostatically charged and efficiently applied to a wide range of surfaces. Boron Nitride powders HeBoFill® can also be used as a solid lubricant additive for oils and greases.
Boron Nitride lubricants and release agents HeBoCoat® are widely used in metal forming and transformation applications. Large areas can be efficiently coated using spray, brush, or immersion. Small areas can be coated using HeBoCoat® SPRAY LINE Boron Nitride aerosol.
HeBoCoat® SPRAY LINE is the range of aerosol-based Boron Nitride coatings.
When choosing among the various product ranges applicable in foundry operations, the following parameters should be considered:
HeBoCoat® – Boron Nitride Coatings in Foundry
Boron Nitride coatings, HeBoCoat®, available in both water-based and ethanol-based formulations, are tailored to meet each customer’s specific requirements.
Each foundry application needs coatings with distinct performance characteristics. As a result, there are three lines of coatings with different properties:
- HeBoCoat® Power Line: This is the most extensive range, featuring products in both ethanol-based and water-based formulations. It is designed for environments or situations requiring non-adhesive and lubricating properties.
- HeBoCoat® Expert Line: A specialised range of coatings designed for the most demanding applications. It is available in a water-based formulation and is the preferred coating when taking things to the next level.
- HeBoCoat® Spray Line: Boron Nitride coating in spray/aerosol form, known for its user-friendly and direct application. It allows for the swift application of non-adhesive and lubricating films without the need for any additional equipment.
HeBoSint® – Sintered Boron Nitride Parts in Foundry
On the other hand, sintered Boron Nitride parts – HeBoSint® – are precision-machined according to the 3D model or plan provided by the customer. This allows for obtaining sintered Boron Nitride parts with specific measurements for their application.
Depending on the environment and work requirements in their application, sintered parts offer different and specific compositions. Therefore, the HeBoSint® range has three product lines:
- HeBoSint® Pure Line: Parts made from pure Boron Nitride, without any binders, and specifically designed for applications requiring high thermal conductivity, low thermal expansion coefficient, and a working temperature of up to 2300°C in a vacuum.
- HeBoSint® Classic Line: A versatile and reliable range of sintered Boron Nitride components. Due to their properties, this range offers the most applications.
- HeBoSint® Strong Line: A line known for its mechanical properties. Exceptional results are achieved by sintering Hexagonal Boron Nitride with Zirconium Dioxide or Aluminum Nitride.
