Welcome to Shot blasting
Shot blasting is a rapid, environment friendly, cost effective surface finishing method which is used for cleaning or polishing metal or other surface by applying high speed stream of shot. In this method, role of shot is to remove impurities, rust, scattered pieces of rubbish or remains that may affect metal strength. This method is carried out to prevent metal fatigue or cracking as well as for cleaning and surface hardening.
Shot blasting process is used to prepare the surface of metal before applying any coating by removing debris and paint. Every industry that uses metal applies this method in daily practices for removing of corrosion, paint and other films and preparing surface for coating. This method produces a roughened texture that improves adhesion of decorative toppings. It leaves the substrate dry or clean which is ready for recoating. Cast iron work is also shot blasted to remove old paint layers.
Shot blast machine mainly consist of six basic parts: blast wheel, cabinet, work handling mechanism, elevator, separator, dust collector. Different machine are used for different purposes like table type machine is used for heavy components and portable air operated machine is used for cleaning casting. The numbers of wheels installed in machine depends on the type of job to be shot blasted and rate of work. Role of shot also depends on work For example: A smaller size steel shot can be used to produce smooth polished surface while large shot can be used to remove heavy flash. In most industries shot blasting works by using wheel with paddle type blades that propel steel shot at surface with high velocity. This entire process is done in an enclosed chamber that separates the dust which is sent to separate dust collector. This entire process is controlled by many factors such as shot impact force, size of shot, rate of machine level and concentration used. Blast machines are used in welded construction industries by facility owners for cleaning, controlling of corrosion and preparing surfaces.Welcom,e to
