BLASTING

Abrasive Blasting involves removing surface film from a part by using abrasive directed at high velocity against the part. Abrasive blasting includes bead, grit, shot, and sand blasting, and may be performed either dry or with water. The primary applications of wet abrasive blasting include: Removing burrs on precision parts; producing satin or matte finishes; removing fine tool marks; and removing light mill scale, surface oxide, or welding scale. Wet blasting can be used to finish fragile items such as electronic components. Also, some aluminum parts are wet blasted to achieve a fine-grained matte finish for decorative purposes. In abrasive blasting, the water and abrasive typically are reused until the particle size diminishes due to impacting and fracture.
There are numerous generic terms for this application usually related to the abrasive media in use; common terms include sand blasting, shot blasting, grit blasting, bead blasting and blast cleaning.
Abrasive Blasting is the operation of cleaning or preparing a surface by forcibly propelling a stream of abrasive material against it. Usually explained as the use of a material against another material to make it smoother, remove surface contaminants or to roughen a surface. It is also the appropriate term for what is known as glass bead blasting, sandblasting, sand carving
Abrasive Blasting is the cleaning or preparing of a surface by forcibly propelling a stream of abrasive material against the surface using sand, aluminum oxide, grit, slag, garnet, steel shot, walnut shells, and others. Abrasive blasting is being used in many different applications to:
Remove rust, scale, and paint;
Roughen surfaces in preparation for bonding, painting or coating;
Remove burr; and/or
Develop a matte surface finish.
Remove flash from molding operation.
Abrasive Blasting is used to clean surfaces such as steel, brick, cement and concrete. A stream of abrasive material is propelled at high speed at a surface using air pressure, water pressure, or centrifugal force. The purpose of the blasting is to remove substances such as rust, scale, paint and graffiti from a surface. Abrasive Blasting equipment involves the use of a blasting pot containing the abrasive material, and a blasting hose with a nozzle attached which is manually controlled by the operator.
Abrasive Blasting can be performed in a blasting chamber or cabinet, or inside temporary erected enclosed outdoor sites, or open sites such as buildings, bridges, tanks, boats or mobile plant.


Shot Blasting

We are using Two different shot blasting processes, and each one is used for a different reason. Unlike straight sandblasting, which is almost always used to remove paint, rust, or other surface material, shot blasting has many more options and uses. Shot medium is sent through a hose using compressed air. Chilled Iron · Chilled iron has much the same properties as garnet, and can be reused. As with the garnet medium, chilled iron should not be used on softer objects which may suffer damage. It has a very rapid cleaning rate and is highly abrasive Sand · Sand is the most commonly used medium in shot blasting. Different grades (size and hardness of the grains) will net different results, depending on the desired result. Sandblasting will remove paint, rust, grease and just about anything else in its way.




Sand Blasting

We provide Sand Blasting on heavy machines and equipment. It is process of smoothing, shaping and cleaning a hard surface by forcibly propelling solid particles across that surface at high speeds. The sand blasting gives similar effect, which produces by using sandpaper. However, it provides more even finish without causing problems at corner or crannies.

The blasting process takes place naturally when particles blown by wind causing aeolian erosion. For artificial blasting, compressed air and blasting equipment is used. In blasting equipment, the chamber is provided in which sand and air are mixed to create artificial blasting. The hand-held nozzle helps the mixture to travels towards the surface. We offer different types of nozzles which come in variety of shapes, sizes, and materials. The nozzles are mainly made of boron carbide which resists from abrasive.



Copperslag Blasting

We provide qualitative Copperslag Blasting service which is usually applied on ships, bridges, tanks, rail cars and water towers. The blasting is mainly used to remove thick, tough heavy dust, rust and paints from heavy machines and tanks. An ebonygrit is formed from a by-product of the manufacturing of copper that is processed into an abrasive by Opta mineral. It is consist of ferrosilicate (Fayalite, Fe2SiO4) material and oxides which is produced when the molten slag is quenched in cold water. The blasting slag is produced by cooling process which breaks the slag into coarse and angular particles.



Grit Blasting

We are a reliable firm, engaged in offering Grit Blasting services to varied industries. The grit blasting process is carried out in heavy and light MS vessels, frames and tanks. In grit blasting process, first the surface is prepared before painting and coating of tanks and frames. The dry abrasive such as steel, aluminum oxide grit is showered on the contaminated surface through jet nozzle. Grit blasting effectively cleans the surface from rust, paint, dirt, grease and exposes parent material.


Benefits:

The blast cleaned surface becomes free from surface contamination like rust and grease.The uniform surface roughness increases the surface area thus provides better bonding with paint or any other coat.It removes surface irregularities like minor dents, scratches, grinding or filing marks.
