The quality of any protective coating depends 70% on surface preparation. EMT's shot blasting and sandblasting equipment guarantee metal cleaning up to the Sa 2.5 standard.
Surface pre-treatment is the most critical yet most easily overlooked step in the entire coating process chain. Research shows that over 70% of coating failure cases are fundamentally caused by improper surface preparation. EMT understands this well and has invested significant resources in the development of surface pre-treatment equipment.
Metal surfaces typically have contaminants such as mill scale, rust, oil, and old coatings before painting. Without thorough removal of these contaminants, even the highest quality paint will develop blistering, peeling, and corrosion problems in a short time. EMT's shot blasting equipment uses high-speed centrifugal projection technology, striking workpiece surfaces uniformly with steel shot at speeds of 70-80 m/s. This not only completely removes all types of contaminants but also creates uniform surface roughness, providing an ideal adhesion base for subsequent coatings.
For workpieces of different materials and shapes, EMT offers multiple pre-treatment solutions: roller conveyor shot blasting machines for continuous processing of plates and structural steel; hook-type shot blasting machines for large structural components; and mobile sandblasting equipment for on-site work. All equipment is fitted with efficient dust collection systems to ensure a clean and safe working environment. Metal surfaces treated by EMT equipment consistently achieve Sa 2.5 cleanliness grade per ISO 8501-1, laying a solid foundation for long-term coating durability.
