It is important to know that the shape of the sand has an important impact on the surface finish of the casting. Circular sand is better than triangular sand because the triangular sand has a large gap, which is easy to lead to defects such as porosity; According to the nature of the casting, the sodium silicate quartz sand is selected to form a spalling layer, and combined with the characteristics of cooling and shrinkage of the casting, the surface defects are reduced. Coating a protective layer on the surface of large castings, such as the film on a coated sand mold, can improve the surface finish of the sand mold and reduce the surface defects of the casting.  

Ensuite, les barres de forage contribuent à améliorer l'efficacité du forage. Une barre de forage de haute qualité peut réduire le temps de forage, diminuer l'usure des équipements et améliorer la précision du perçage. Par conséquent, des barres de forage conçues avec soin peuvent traduire des économies considérables pour les entreprises qui opèrent sur le terrain.

Applications of DTH Hammer Drilling

Una de las funciones más importantes de los chocks es brindar estabilidad. Durante el proceso de laminado, las fuerzas ejercidas sobre el metal pueden ser extremas. Los chocks aseguran que los rodillos permanezcan en la posición correcta, evitando desplazamientos que puedan afectar la calidad del producto final. Además, una alineación inadecuada puede provocar una distribución desigual de la presión sobre el metal, lo que puede resultar en defectos o incluso en daños a la maquinaria.

- Repair Work Whether in vehicle repair or household fixes, having the right tool for specific tasks can make all the difference. A fractional head hammer provides the flexibility needed to handle various repairs effectively, ensuring that users can adapt the tool to the job at hand.
