Sand blasting is basically used to clean the surface of any material, mainly for the metallic surface. It is one of the most efficient and quick method which uses compressed air to blast fine sand through a nozzle to shape and smooth surface of any foreign material. It is well suited for the removal of rust which causes property damage.
It is used not only to remove rust but to prepare surface for high performance coatings or to treat final products to give them luster and surface texture desired by the retail consumer. Materials used in sand blasting are sand, copper slog, steel grit, pieces of walnut, powder abrasive, pieces of avocado and many others.
These different types of materials have different shape, hardness and density. Each of this material has some unique application within the industry. Use of silica sand as abrasive material in sand blasting is banned in many countries because silica sand easily breaks up cause’s large amount of dust. Extended inhalations of dust by workers who are involved in the process of sand blasting suffer from serious disease named silicosis of lungs.
Secondly sand contains high moisture content that can lead to the premature demise of blasting equipment. Instead of sand we use steel grit for removing rust sand layers of paint from thick metal surface and crushed glass for light surface which could be damaged, if we use other heavier materials.
There are many equipment used in sand blasting are batch type system, through feed system, hanger type system and manipulator type system.
Quality Spares Centre is one of the best Sand blasting machine manufactures in Farridabad, India and they are also an eminent organization that has become the primary choice of companies based in India and abroad due to a variety of factors. Some of the reasons that have enabled us to scale the pinnacle of this line of work are as follows:-
Normally, for a novice, sandblasting equipment is nothing but a machine to wipe out dust and debris from a surface. But it needs some basic study before going in to purchasing a sandblasting system. For guidance and reference purpose, we detail below a few points that the purchaser must adhere to:
Choice of Finish Required: Different sandblasting systems are intended for different needs and finish. Some use harsh abrasives while other machines have soft effect resin sand and there are also machines that use media mixed with water or liquid sandblaster to give a completely different result. So it is advisable to first identify what method customer needs. While grit blasting uses silicon carbide, walnut shells for surfaces where metal blasting could damage them, shot blasting is intended for heavy metal blasting in grit, grease and chip removal. Light work to smoothen down walls and surfaces is achieved by grit method.
Painting Requirement: If going for painting, texturing a rugged base on the surface will be ideally acceptable through abrasive shot blasting that is silicon dust free and less polluting.
Quality spares centre is manufacturers of metal Sand blasting machines & associated equipments that are used in various industries. The range is fabricated from various materials, ranging from aluminium to walnuts and from steel to specially formulated plasticized PVC compounds.
Sample Technique: We have various types of blasting equipments in the market that create different consistency and feel to the surface. By going through a trail of various samples created by the blasting machine on dissimilar media, our choice becomes quite apparent what we type of machine we should purchase.
Production Prerequisite: Selection of the right blasting system is judged by the essence of necessity and production efficiency of a company. Customer has to recognize his exact process needs so the best machine can be discovered. Finding the right one from automatic type, semi-automatic type, pressure feed or suction type all have their own processing capacity.
Small or Large Blasting Area: If the work piece size is small then a moderate sized blaster will suffice, but definitely for bigger areas or larger equipments, a wheel blasting machine is generally deployed.
Compressed Air Requirement: Since the blasting system has categories in power consumption and output and variation in air compressor output, one must only select machine of a higher power air compressor and that its compressor output should be 20% higher than necessitated to protect the compressor from stress.
After Sales and Service: After all conditions are met and the deal finalized, customer must clear every query related to service and maintenance of the machine if some trouble happens. It could include location of the repair center, onsite check and correction of the system, easy approach to repair center from workplace, satisfactory repairs, warranty and free checks.
Price: Definitely the last but the strongest point is the price of the blaster. Although there could be cheap blasters in the market, but regular use could compromise their quality. So it is always wise to buy a good product from a professional supplier so that its performance can cut cost after from its longer running period.
