CastoDyn DS800 CastoDyn DS800 Advanced modular oxy-acetylene thermal spray system, designed to spray a wide range of alloys and other materials for very many different applications. Can be integrated into automated installations for mass-production applications. Thermal spray torch for coating and rebuilding a very wide variety of mechanical components. For “cold” thermal spraying of RotoTec and ProXon alloy powders without deformation or structural change of the part. For “hot” thermal spraying of Eutalloy RW alloy powders for dense, porosity-free deposits. The range of alloys provides excellent resistance to wear from metal to metal friction, corrosion, abrasion to erosion.
