Coating Preparation: Essential for Foundry Applications

In foundries, coating preparation is key to ensuring the durability and performance of molds and cores. Proper preparation creates the ideal conditions for adhesion, heat resistance, and a flawless casting surface.

Achieving the right balance between density and viscosity is crucial:

Density ensures even application and prevents casting defects like metal penetration.
Viscosity allows the coating to flow smoothly, ensuring uniform coverage on complex mold geometries.

Modern foundry coatings are designed for thermal resistance, smooth surface finishes, and gas permeability to reduce casting defects. With precise preparation and advanced machinery, coatings help produce high-quality, defect-free castings, improving efficiency and end results.

At HBF Techniek, we are proud to have been a trusted partner of Foseco for nearly a decade. This long-standing collaboration has enabled us to play a key role in developing and manufacturing cutting-edge machines for the preparation and application of foundry coatings.

Our machines are designed to deliver precision and consistency, ensuring that coatings meet the highest standards for density, viscosity, and uniformity. By combining our engineering expertise with Foseco’s in-depth knowledge of coating materials, we provide solutions that enhance efficiency and quality in foundry operations.

This partnership reflects our commitment to supporting the foundry industry with innovative technologies that optimize every step of the coating process, from preparation to application, helping our customers achieve durable and defect-free castings.

Dipping single
H-ICU for Dipping Single: Controlling the coating mixture is important for achieving the correct coating layer thickness on the casting molds. The ICU-H can easily be installed on the existing dip-tank or mixing tank. It automatically maintains the optimal coating dilution by continuously measuring and precisely adjusting the mixture during coating batch preparations and operations. The process is displayed and recorded using the advanced data manager. The controls allow for easy adjustment of settings, such as optimal coating density. All measurement and mixture adjustment data can be accessed remotely through Ethernet, WebDAV, or via USB. The ICU-H basically performs three integrated functions: • Density control • Level control • Data logging The density of the coating mixture in the tank is determined using two high precision ceramic pressure sensors. Based on this measurement, the density is regulated by adding water and undiluted coating using automatically controlled valves. The flowmeters provide a feedback-loop on added volumes.
