Abrasive blasting stands as a pivotal process in surface treatment, where the efficiency and outcome largely depend on the quality of the operating mix. This mix, a dynamic combination of abrasive particles, plays a key role in determining the efficiency and effectiveness of the blasting process.
In the world of surface preparation, the accuracy of cleanliness assessment is crucial. It not only influences the quality of the final application but also ensures the durability and adherence of the coating. A shift from traditional methods to more advanced, precise tools has revolutionized how cleanliness is evaluated.
Traditionally, evaluating surface cleanliness involved the use of a x30 magnifier, a method dependent on the operator's expertise and subject to a degree of subjectivity. This approach, while having its merits, pales in comparison
Airblasting operations are a critical component of surface preparation and finishing processes, demanding meticulous control over various parameters to ensure optimal outcomes. The effectiveness of airblasting is profoundly influenced by factors such as pressure, nozzle diameter, dust control, cleanliness, and surface roughness. Understanding the "why" behind the need for precise monitoring reveals the significance of achieving desired specifications, which in turn, enhances the quality, efficiency, and safety of airblasting operations.
Surface preparation for pipe coating in the oil and gas industry is a process that demands precision and attention to detail. Given the industry's stringent requirements, where pipes are often expected to have a lifespan exceeding 25 years, every aspect of the preparation process becomes critical. The dual goals of this process are to remove any scale or rust and to create the most suitable surface profile for coating adhesion.
Descaling in the metalworking industry, especially for coils and plates, is a vital process post-lamination. After being subjected to high temperatures during lamination, coils and plates often develop a layer of scale on their surface. This scale, if not removed, can hamper further processing and affect the quality of the final product. While acid bath treatments are commonly used, blasting is essential to maximize scale removal and prolong the life of these acid baths.
Effective April 1, 2024, Seoul Shot Industry Co., Ltd. will officially change its name to Winoa Korea Co., Ltd.
Since joining the Winoa Group, a global leader in metal surface cleaning, in 1999, Seoul Shot Industry has established itself as a frontrunner in the Korean metal abrasives industry, experiencing steady growth and success. This name change marks a significant milestone in the company's journey, solidifying its position as Winoa's Korean sales subsidiary and reinforcing its commitment to further growth and collaboration with the Winoa Group.
Desanding in foundry is a critical post-casting process that ensures the quality and functionality of metal parts. During casting, liquid metal is poured into a sand mold. Once the metal cools and solidifies, it emerges encased in a hard, sticky layer of sand. The primary objective in desanding is to remove this sand completely without damaging the part, preparing it for subsequent machining operations.

Metal surface treatment is an essential aspect of industrial manufacturing, impacting the durability, efficiency, and quality of metal products. This overview explores various critical applications, each tailored to specific needs and challenges in the field.
Forging processes often result in scale formation on metal parts. Descaling in forging involves removing this scale to ensure quality and prepare the surface for further operations. Techniques include abrasive blasting with specific materials like S390 to S660 and GP18 t
There are some low-priced shot ball suppliers who ignore quality.
However, Winoa Korea Co., Ltd. goes beyond being a supplier of quality products.
We aim to be a partner who can find the best solution with our customers.
The sandblasting process is a mechanical technique for the controlled cleaning of a surface, usually metallic. It is made by erosion thanks to the abrasion generated by propelling metal shots or grit with compressed air lances.
Another method uses wheel blasting machines. The sandblasting process, in addition to allowing the surface of a metal product to be cleaned from residues and corrosive scales, can also be used to obtain a particular
