Shot peening is a cold working process in which the surface of a part is bombarded with small spherical media called shot. Each piece of shot striking the metal acts as a tiny peening hammer imparting a small indentation or dimple on the surface. In order for the dimple to be created, the surface layer of the metal must yield in tension . Below the surface, the compressed grains try to restore the surface to its original shape producing a hemisphere of cold-worked metal highly stressed in compression. Overlapping dimples develop a uniform layer of residual compressive stress. It is well known that cracks will not initiate nor propagate in a compressively stressed zone. Since nearly all fatigue and stress corrosion failures originate at or near the surface of a part, compressive stresses induced by shot peening provide significant increases in part life. The magnitude of residual compressive stress produced by shot peening is at least as great as half the tensile strength of the material being peened. In most modes of long term failure the common denominator is tensile stress. These stresses can result from externally applied loads or be residual stresses from manufacturing processes such as welding, grinding or machining. Tensile stresses attempt to stretch or pull the surface apart and may eventually lead to crack initiation . Compressive stress squeezes the surface grain boundaries together and will significantly delay the initiation of fatigue cracking. Since crack growth is slowed significantly in a compressive layer, increasing the depth of this layer increases crack resistance. Shot peening is the most economical and practical method of ensuring surface residual compressive stresses.

We are offering shot blasting glass beads use to clear moulds & surfaces.

Most glass fillers are short strands of glass fibre but there are an increasing number of long strand grades becoming available. The long strand versions can provide greater strength over the more traditional short strand varieties. It should be stressed at this point that the design of the part will still have a big impact on the final strength as the orientation of the fibres will be affected by the flow of the material. Also, the injection moulding process will break some of the fibres, particularly in the case of long strands. A coupling agent may be used to improve adhesion between the fibres and the polymer. This results in a more even distribution of the fibres which is retained during the moulding process. As a result, coupled materials, as opposed to filled, will often demonstrate higher impact strength properties. There are also nylons filled with glass beads. These will improve compressive strength, heat deflection temperature, tensile strength and modulus (stiffness) when compared with unfilled grades. Furthermore, when compared with glass fibres they are easier to process, have uniform and predictable shrinkage and minimum warpage. As a reinforcement filler for plastics and resins : Beads are being used as reinforcement filler in the plastic industry. Size of the glass beads being used for this purpose is 710 microns are below. Depending upon the job, bigger size is also being used. For better bond between Glass Beads and plastics, beads are silicon coated. Spherical shape gives better stress patterns than the irregular shaped particle conventionally used. Beads are easily and uniformly dispersed throughout the plastic compound and produce smooth flowing compound which distributes itself evenly, so that all parts of any shaped moulding can be reinforced and the strong corners and edges. Reinforcement with Glass beads will improve the tensile strength, reduce elongation, increase flexural modulus and in some plastic triple the compressive strength of the finished product. It can be used to reinforce thermosetting resigns, such as polyester, epoxy and phenolic. They are also used to reinforce ABS, Vinyl and nylon. Given below are the few examples :

• In adhesives to increase the bound strength.
• In Epoxy plotting compounds for electronic devices in dental fillings and appliances for good compressive strength.
• In fiberglass-epoxy laminates for improved flexural strength.
• In moulded phenolic motor housing for good insulation.
